    Change detection techniques aim to identify changes between two or more images taken at different times. In this paper, we explore the capabilities of identifying changes in an unsupervised manner between different soil types using two laboratory HySpex imaging spectroscopy sensors in the visible near infrared (VNIR) and short-wave infrared (SWIR) spectral ranges. The experiment was carried under controlled laboratory conditions with the same lighting and no atmospheric distortions. The 69 selected soil samples covered the arid and semiarid climate zones of Israel. The well-known change vector analysis technique was used to generate the difference image, and several thresholding methods were tested to generate the final binary change map. The performance capabilities of the VNIR, SWIR and combined VNIR–SWIR sensors were examined. Our study demonstrates that changes in different soil types can be identified using imaging spectroscopy sensors; the SWIR sensor generated better change detection capabilities than the VNIR sensor, and the combination of the two sensors did not outperform the SWIR sensor alone. Results showed that it is important to combine a spectral domain thresholding approach with a spatial domain thresholding approach. The benefit of combining these approaches is a low false-alarm rate with a relatively high probability of detection. Although the change experiment was conducted under almost perfect conditions without any atmospheric or lighting differences, the change detection techniques did not detect all soil type changes and changes between spectrally similar soils remain undetected. The results of this study can be further extended to other spatial scales and can provide a foundation for soil change detection using upcoming imaging spectroscopy satellite platforms that acquire spatial–spectral–temporal information.

    WOS: 000278356000005 This study has been done to determine the effects of zinc, applied at different doses and in different ways in the fields where NPK was used and also not used as a base fertilizer on the yield and quality of the grape type of Hesapali grown widely in the environs of Aladag, Hadim, and Konya. The test has been applied to the vine grapevine at the doses of 0, 10, 20, 40g Zn/grapevine for both the ones to which NPK was not applied (N0P0K0.) and to which NPK was applied (150-50-50 g/grapevine N1P1K1) in the form of ZnSO(4)7H(2)O. Zn application has been performed in two different forms: I. By mixing all the zinc with the soil (20-30 cm depth) in the projection of the grapevine 15 days before blossom and II. By spraying j of all the zinc over the leaves with a fifteen-day interval at 4 times, which starts 15 days before blossom. According to results of the study: Wet grape yield obtained from each grapevine, which was exposed to the average of two different applications (N0P0K0 and N1P1K1) forms of zinc has statistically increased in an important proportion by increasing the dose of zinc applied to the grapevine. Comparing with the controls, the highest yield of wet grape with the proportion of 212% and 206% has been obtained in N0P0K0 and N1P1K1 applications by applying 10 and 40gram of zinc to each grapevine. Beside as an average of NPK and zinc levels, application of zinc over leaves has increased the yield of the wet grape more than the one applied to the soil (7.00 b and 8.4 a kg grape/grapevine). Moreover water soluble dry matter (%), and titratable acidity (g/100 cc) of grape with rising zinc doses, has increased as an average of NPK and zinc application and, the most water soluble dry matter (18.91%) and titratable acidity (2.74g/100cc) has been obtained by application of 20g Zn/grapevine.

It was aimed tofind the location and situation of drainage systems by ground penetrating radar (GPR)method, and to relate with inconsistent soil characteristics. Four (4) different area wereselected to represent the study area. For each of the selected area, seven (7) profiles of150 m (area 2, 3 and 4) and 200 m (area 1) were designated at 5 m intervals and datawas collected through ground penetrating radar, 228 soil samples from the whole areawere collected at the same time with ground penetrating radar. For the purpose ofcomparison, profile pit sampling was carried out on the surrounding fields 150 m awayfrom the study area. Analysis of pH, electrical conductivity, lime content, organicmatter content, particle size distribution, hydraulic conductivity, exchangeable Nacontent, cation exchange capacity and bulk density were performed on the soil samples.Analysis results were evaluated by inverse distance weighting interpolation method(IDW). Electrical conductivity, pH, organic matter, particle size, cation exchangecapacity, exchangeable sodium rate and bulk density results obtained by interpolationwere compatible with the results of the soil analysis. It was tried to determine theposition of current drainage line from the data collected in the study area by groundpenetrating radar; however, dense clay and high capillary fringe in the environmenthindered the determination of the exact location of the pipes. Ground water level in thestudy area was determined using ground penetrating radar data.Key Words: Drainage Systems, GPR, Drain Pipe, Spatial Variability, 291

    A pesquisa sobre a avaliação da disponibilidade de manganês tem apresentado resultados discordantes, em grande parte em decorrência dos teores considerados disponíveis pelos diversos extratores. O conhecimento das formas químicas em que se encontra o elemento e suas relações com os teores disponíveis são importantes para a previsão do seu comportamento no sistema solo-planta. Nesse sentido, este trabalho teve como objetivo estudar a influência da calagem e de doses de manganês sobre a dessorção, extração e fracionamento desse elemento em amostras de seis Latossolos. Essas amostras, submetidas ou não à calagem, receberam o manganês nas doses de 0, 16 e 32 mg dm-3 e permaneceram incubadas por 30 dias. Terminada a incubação, o Mn foi determinado utilizando-se os extratores Mehlich-1, Mehlich-3, DTPA e EDTA. As amostras foram submetidas a um fracionamento que separou o Mn na fração trocável (Tr), matéria orgânica (MO), óxido de manganês (OxMn), óxido de ferro amorfo (OxFeA), óxido de ferro cristalino (OxFeC) e residual (R), além dos teores totais. A dessorção foi avaliada mediante extrações sucessivas com resina de troca catiônica. Concluiu-se que o elemento foi retido, principalmente, na fração trocável e matéria orgânica. De modo geral, a calagem provocou redução nos teores trocáveis e aumento nas frações óxidos de ferro amorfo e de manganês. Na ausência da calagem, a ordem de dessorção apresentada foi Tr >> MO > OxFeA, com o Mehlich-3 sendo o melhor extrator para o Mn lábil. A calagem provocou acentuado decréscimo nos teores de Mn dessorvidos. O Mehlich-1 mostrou-se inadequado para a determinação dos teores disponíveis de Mn em solos corrigidos, condição na qual o DTPA foi o extrator mais indicado. Conflicting results have been achieved by the evaluation of manganese availability in soil, largely a consequence of varying values denoted as available by different extractants. Knowledge on the element's chemical forms in the soil and on relationships with the available concentrations are important to predict its behavior in the soil-plant system. In this study, six Oxisol soil samples were analyzed to evaluate the influence of liming and different manganese doses on desorption, extraction and fractioning. These soil samples, with and without lime application, were treated with manganese doses (0.0, 16.0 and 32.0 mg dm-3) and then incubated for 30 days. Hereupon, Mn was extracted with Mehlich-1, Mehlich-3, DTPA and EDTA. and determined by atomic adsorption spectrophotometry. Additionally, the samples were fractionated for determination of manganese in the fractions: exchangeable (Ex), organic matter (OM), manganese oxides (MnOx), amorphous iron oxides (AFeOx), crystalline iron oxides (CFeOx), and residual (Re), as well as the total concentrations of the micronutrient. Micronutrient desorption was evaluated by successive extractions with cation exchange resin. Results showed that Mn was mainly retained in the exchangeable and organic matter fractions. In general, liming reduced exchangeable contents and increased the oxide fractions of amorphous iron and manganese. Without lime, the desorption order for Mn was Ex >> OM > AFeOx, where Mehlich-3 proved to be the best extractor for the determination of labile Mn concentrations. Liming caused a considerable decrease in Mn desorption. Under the same condition, Mehlich-1 proved to be inefficient to determine available Mn contents, while DTPA was the best extractant.

    In order to determine the nutritional status of olive orchards in Hatay-Altınözü district, texture, lime (CaCO3), pH, electrical conductivity (EC), organic matter and some macro-micro nutrient element analyzes were performed on 30 soil and 15 plant samples taken from selected olive orchards. According to the results obtained from the research, the soils were found to be in clay and clay-loam texture class, with slightly alkaline reaction, unsalted, excessively calcareous and insufficient in organic matter. it was determined that all the soils were insufficient in nitrogen (N), except for one sample, 100.0% zinc (Zn) and boron (B), 6.66% phosphorus (P), 13.33% potassium (K), 10.0% iron (Fe) contents. In the olive leaf samples, 20% N, 6.66% P, 36.66% K, 53.33% calcium (Ca), 73.33% magnesium (Mg), 46.66% both manganese (Mn), It was determined that it was deficient in terms of Zn and B contents. In the study, when soil and leaf analyze are examined, some plant nutrients are sufficient or more (Ca, Mg) in the soil, while they are deficient in the plant. Some plant nutrients are deficient in the soil (Zn, B), but they are found to be sufficient in the plant. This shows that there are nutritional problems and unconscious soil and leaf fertilization is done in the region. As a result, it is suggested that the producers should make fertilization programs by a specialist according to the missing or excess plant nutrient element status by having plant and soil analyzes done.

    Small balsam, or Impatiens parvifl ora, is one of the most invasive herbaceous alien species in European temperate forests, and is increasingly found in the same sites as its native congener I. noli-tangere. The aim of this study was to explore the habitat range of both species and determine whether overlap occurs. Vegetation surveys were conducted in 13 Belgian sites. We performed 139 relevés according to the following stratifi cation: pure plots of the invasive balsam, pure plots of the native balsam, mixed plots with both species and plots without either of the two species. Soil characteristics were analyzed (pH, organic matter, C/N ratio and cations) and Ellenberg indicator values were used for light and soil moisture. We assessed species affi nities for both Impatiens using indicator species analysis. Discriminant analysis was carried out to assign the sample plots to certain vegetation types. Vegetation and soil characteristics indicated that the species have considerable habitat overlap. This overlap is indicated by similar communities among relevés and by the failure of discriminant analysis to correctly assign plots. Populations of both Impatiens species are surrounded by an unsuitable habitat that probably limited their spread. In conclusion, we predicted that the alien balsam could spread rapidly with the help of human disturbance and transport, and could compete with the native congener.

    Authors: Štula, Uroš;

    U današnje vrijeme trendovi proizvodnje hrane sve više rastu, a dodatna opterećenja za poljoprivrednu proizvodnju predstavlja i kontinuirani rast stanovništva uz sve izraţenije klimatske promjene. Trenutno se pokušava poljoprivredna proizvodnja prilagoditi novonastaloj situaciji, a jedan od načina je primjenjivati gnojiva u dozama koje neće negativno utjecati na okoliš i prinos usjeva. Istraţivanje se temeljilo na uzorkovanju i kemijskoj analizi tla, a dobiveni podaci korišteni su za izračun optimalne gnojidbe uz pomoć ALRxp modela za pet ratarskih usjeva. Najveće potrebe za NPK gnojivom (7:20:30) imala je šećerna repa u iznosu od 476,8 kg ha1,a najmanje potrebe je imala pšenica sa 253,7 kg ha-1. Prema preporuci kukuruz je imao najveću prosječnu preporučenu dozu dušikom u iznosu od 132,9 kg ha-1, a najmanju je imala soja sa 62 kg N ha-1. Ovakav način izračuna gnojidbenih preporuka temeljen na stvarnim podacima uvelike moţe pomoći poljoprivrednim proizvoĎačima prilikom planiranja proizvodnje kao i kod odabira optimalnog gnojiva za odabrani usjev. Nowadays food production trends are growing and additional load for agricultural production presents a continuous growth of population with all the more pronounced climate change. Currently agricultural production is attempting to adapt to a new situation and one way is to apply fertilizer in doses which will not have a negative impact at environment and crops yield. The research was based on sampling and chemical analysis of soil, and obtained data was used for calculation optimal fertilization with ALRxp model for five crops. The greatest need for NPK fertilizer (7:20:30) has sugar beet in the amount of 476.8 kg ha-1, and the smallest need has wheat with 253.7 kg ha-1. According to the recommendation maize has the highest recommended dose of nitrogen in the amount of 132.9 kg ha-1, and the smallest has soybean with 62 kg N ha-1. This way of calculating fertilization recommendations based on real data can help agricultural producers when planning production as well with selection optimal fertilizer for selected crops.

    The determination of total organic carbon in soils, fertilizers, sewage sludge, sediments, and humic extracts is widely performed by chemical oxidation methods with K2Cr2O7. The Yeomans-Bremner (YB) method is currently the one that stands out the most. The drawback of these methods is the large amount of concentrated H2SO4 used, which generates a large amount of hazardous waste. This work proposes using KMnO4 as an alternative to K2Cr2O7 for a lower consumption of H2SO4. The method uses the back titration of Fe2+ added to consume both the MnO2 produced and the excess KMnO4 that was not consumed in the OM oxidation. A non-trivial and yet not explored stoichiometry was applied for this purpose, providing a success not yet achieved in using permanganate to determine TOC by titration. The ideal condition for the oxidation of OC was determined by the analysis of a potassium hydrogen phthalate standard and involved the use of 0.125 mol L-1 H2SO4 and temperature of 70 °C, obtaining a significant advantage over the YB method (concentrated H2SO4 and 170 °C). The proposed method was applied to the analysis of soil samples, producing conversion factors for soil organic carbon that varied between 0.652 and 1.12.

    Change detection techniques aim to identify changes between two or more images taken at different times. In this paper, we explore the capabilities of identifying changes in an unsupervised manner between different soil types using two laboratory HySpex imaging spectroscopy sensors in the visible near infrared (VNIR) and short-wave infrared (SWIR) spectral ranges. The experiment was carried under controlled laboratory conditions with the same lighting and no atmospheric distortions. The 69 selected soil samples covered the arid and semiarid climate zones of Israel. The well-known change vector analysis technique was used to generate the difference image, and several thresholding methods were tested to generate the final binary change map. The performance capabilities of the VNIR, SWIR and combined VNIR–SWIR sensors were examined. Our study demonstrates that changes in different soil types can be identified using imaging spectroscopy sensors; the SWIR sensor generated better change detection capabilities than the VNIR sensor, and the combination of the two sensors did not outperform the SWIR sensor alone. Results showed that it is important to combine a spectral domain thresholding approach with a spatial domain thresholding approach. The benefit of combining these approaches is a low false-alarm rate with a relatively high probability of detection. Although the change experiment was conducted under almost perfect conditions without any atmospheric or lighting differences, the change detection techniques did not detect all soil type changes and changes between spectrally similar soils remain undetected. The results of this study can be further extended to other spatial scales and can provide a foundation for soil change detection using upcoming imaging spectroscopy satellite platforms that acquire spatial–spectral–temporal information.

    WOS: 000278356000005 This study has been done to determine the effects of zinc, applied at different doses and in different ways in the fields where NPK was used and also not used as a base fertilizer on the yield and quality of the grape type of Hesapali grown widely in the environs of Aladag, Hadim, and Konya. The test has been applied to the vine grapevine at the doses of 0, 10, 20, 40g Zn/grapevine for both the ones to which NPK was not applied (N0P0K0.) and to which NPK was applied (150-50-50 g/grapevine N1P1K1) in the form of ZnSO(4)7H(2)O. Zn application has been performed in two different forms: I. By mixing all the zinc with the soil (20-30 cm depth) in the projection of the grapevine 15 days before blossom and II. By spraying j of all the zinc over the leaves with a fifteen-day interval at 4 times, which starts 15 days before blossom. According to results of the study: Wet grape yield obtained from each grapevine, which was exposed to the average of two different applications (N0P0K0 and N1P1K1) forms of zinc has statistically increased in an important proportion by increasing the dose of zinc applied to the grapevine. Comparing with the controls, the highest yield of wet grape with the proportion of 212% and 206% has been obtained in N0P0K0 and N1P1K1 applications by applying 10 and 40gram of zinc to each grapevine. Beside as an average of NPK and zinc levels, application of zinc over leaves has increased the yield of the wet grape more than the one applied to the soil (7.00 b and 8.4 a kg grape/grapevine). Moreover water soluble dry matter (%), and titratable acidity (g/100 cc) of grape with rising zinc doses, has increased as an average of NPK and zinc application and, the most water soluble dry matter (18.91%) and titratable acidity (2.74g/100cc) has been obtained by application of 20g Zn/grapevine.

It was aimed tofind the location and situation of drainage systems by ground penetrating radar (GPR)method, and to relate with inconsistent soil characteristics. Four (4) different area wereselected to represent the study area. For each of the selected area, seven (7) profiles of150 m (area 2, 3 and 4) and 200 m (area 1) were designated at 5 m intervals and datawas collected through ground penetrating radar, 228 soil samples from the whole areawere collected at the same time with ground penetrating radar. For the purpose ofcomparison, profile pit sampling was carried out on the surrounding fields 150 m awayfrom the study area. Analysis of pH, electrical conductivity, lime content, organicmatter content, particle size distribution, hydraulic conductivity, exchangeable Nacontent, cation exchange capacity and bulk density were performed on the soil samples.Analysis results were evaluated by inverse distance weighting interpolation method(IDW). Electrical conductivity, pH, organic matter, particle size, cation exchangecapacity, exchangeable sodium rate and bulk density results obtained by interpolationwere compatible with the results of the soil analysis. It was tried to determine theposition of current drainage line from the data collected in the study area by groundpenetrating radar; however, dense clay and high capillary fringe in the environmenthindered the determination of the exact location of the pipes. Ground water level in thestudy area was determined using ground penetrating radar data.Key Words: Drainage Systems, GPR, Drain Pipe, Spatial Variability, 291

    A pesquisa sobre a avaliação da disponibilidade de manganês tem apresentado resultados discordantes, em grande parte em decorrência dos teores considerados disponíveis pelos diversos extratores. O conhecimento das formas químicas em que se encontra o elemento e suas relações com os teores disponíveis são importantes para a previsão do seu comportamento no sistema solo-planta. Nesse sentido, este trabalho teve como objetivo estudar a influência da calagem e de doses de manganês sobre a dessorção, extração e fracionamento desse elemento em amostras de seis Latossolos. Essas amostras, submetidas ou não à calagem, receberam o manganês nas doses de 0, 16 e 32 mg dm-3 e permaneceram incubadas por 30 dias. Terminada a incubação, o Mn foi determinado utilizando-se os extratores Mehlich-1, Mehlich-3, DTPA e EDTA. As amostras foram submetidas a um fracionamento que separou o Mn na fração trocável (Tr), matéria orgânica (MO), óxido de manganês (OxMn), óxido de ferro amorfo (OxFeA), óxido de ferro cristalino (OxFeC) e residual (R), além dos teores totais. A dessorção foi avaliada mediante extrações sucessivas com resina de troca catiônica. Concluiu-se que o elemento foi retido, principalmente, na fração trocável e matéria orgânica. De modo geral, a calagem provocou redução nos teores trocáveis e aumento nas frações óxidos de ferro amorfo e de manganês. Na ausência da calagem, a ordem de dessorção apresentada foi Tr >> MO > OxFeA, com o Mehlich-3 sendo o melhor extrator para o Mn lábil. A calagem provocou acentuado decréscimo nos teores de Mn dessorvidos. O Mehlich-1 mostrou-se inadequado para a determinação dos teores disponíveis de Mn em solos corrigidos, condição na qual o DTPA foi o extrator mais indicado. Conflicting results have been achieved by the evaluation of manganese availability in soil, largely a consequence of varying values denoted as available by different extractants. Knowledge on the element's chemical forms in the soil and on relationships with the available concentrations are important to predict its behavior in the soil-plant system. In this study, six Oxisol soil samples were analyzed to evaluate the influence of liming and different manganese doses on desorption, extraction and fractioning. These soil samples, with and without lime application, were treated with manganese doses (0.0, 16.0 and 32.0 mg dm-3) and then incubated for 30 days. Hereupon, Mn was extracted with Mehlich-1, Mehlich-3, DTPA and EDTA. and determined by atomic adsorption spectrophotometry. Additionally, the samples were fractionated for determination of manganese in the fractions: exchangeable (Ex), organic matter (OM), manganese oxides (MnOx), amorphous iron oxides (AFeOx), crystalline iron oxides (CFeOx), and residual (Re), as well as the total concentrations of the micronutrient. Micronutrient desorption was evaluated by successive extractions with cation exchange resin. Results showed that Mn was mainly retained in the exchangeable and organic matter fractions. In general, liming reduced exchangeable contents and increased the oxide fractions of amorphous iron and manganese. Without lime, the desorption order for Mn was Ex >> OM > AFeOx, where Mehlich-3 proved to be the best extractor for the determination of labile Mn concentrations. Liming caused a considerable decrease in Mn desorption. Under the same condition, Mehlich-1 proved to be inefficient to determine available Mn contents, while DTPA was the best extractant.

    In order to determine the nutritional status of olive orchards in Hatay-Altınözü district, texture, lime (CaCO3), pH, electrical conductivity (EC), organic matter and some macro-micro nutrient element analyzes were performed on 30 soil and 15 plant samples taken from selected olive orchards. According to the results obtained from the research, the soils were found to be in clay and clay-loam texture class, with slightly alkaline reaction, unsalted, excessively calcareous and insufficient in organic matter. it was determined that all the soils were insufficient in nitrogen (N), except for one sample, 100.0% zinc (Zn) and boron (B), 6.66% phosphorus (P), 13.33% potassium (K), 10.0% iron (Fe) contents. In the olive leaf samples, 20% N, 6.66% P, 36.66% K, 53.33% calcium (Ca), 73.33% magnesium (Mg), 46.66% both manganese (Mn), It was determined that it was deficient in terms of Zn and B contents. In the study, when soil and leaf analyze are examined, some plant nutrients are sufficient or more (Ca, Mg) in the soil, while they are deficient in the plant. Some plant nutrients are deficient in the soil (Zn, B), but they are found to be sufficient in the plant. This shows that there are nutritional problems and unconscious soil and leaf fertilization is done in the region. As a result, it is suggested that the producers should make fertilization programs by a specialist according to the missing or excess plant nutrient element status by having plant and soil analyzes done.

    Small balsam, or Impatiens parvifl ora, is one of the most invasive herbaceous alien species in European temperate forests, and is increasingly found in the same sites as its native congener I. noli-tangere. The aim of this study was to explore the habitat range of both species and determine whether overlap occurs. Vegetation surveys were conducted in 13 Belgian sites. We performed 139 relevés according to the following stratifi cation: pure plots of the invasive balsam, pure plots of the native balsam, mixed plots with both species and plots without either of the two species. Soil characteristics were analyzed (pH, organic matter, C/N ratio and cations) and Ellenberg indicator values were used for light and soil moisture. We assessed species affi nities for both Impatiens using indicator species analysis. Discriminant analysis was carried out to assign the sample plots to certain vegetation types. Vegetation and soil characteristics indicated that the species have considerable habitat overlap. This overlap is indicated by similar communities among relevés and by the failure of discriminant analysis to correctly assign plots. Populations of both Impatiens species are surrounded by an unsuitable habitat that probably limited their spread. In conclusion, we predicted that the alien balsam could spread rapidly with the help of human disturbance and transport, and could compete with the native congener.
