    An assessment of soil nutrient status based on farmers’ samples was carried out in the Capricorn, Sekhukhune, and Waterberg Districts of the Limpopo Province of South Africa. A total of 336 soil samples were collected and analysed for pH, phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg). The results showed that the pH of more than 80% of the submitted soil samples was suitable for the production of most field crops ,while less than 20% required liming to make them productive. Phosphorus levels were very low (<8 mg kg-1), with most soils (≥95%) needing P fertilisation to improve crop yields. Potassium was adequate (>250 mg kg-1) for most districts' crops. Between 70% and 74% of soils from Sekhukhune and Waterberg Districts were deficient in Ca (<200 mg kg-1). Magnesium was adequate (>300 mg kg-1) in more than 60% of the analysed samples. Apart from soil pH, all soil properties showed a high degree of variability across all districts. Further studies are needed to investigate the role of field management, crop rotation, field position in the landscape, lithology, and socioeconomic conditions of the farmer on the observed trends of soil nutrients.

  • Authors: Jonkershoek Forestry Research Center;

    This is a scanned copy of a soil analysis report in Kogelberg, site 3418BD, including a map. The Jonkershoek Forestry Research Center (part of the former South African Forestry Research Institute) was established in 1935 at Jonkershoek, near Stellenbosch, under the directorship of Dr C. L. Wicht. The initial aim was to determine how forestry activities in state plantations would affect climate, water conservation and erosion, and was later expanded to include studies of fynbos ecology, fire and alien species. Studies from the 1930s to the early 1990s saw the accumulation of a large amount of data dealing with fire experiments, detailed vegetation plot surveys, rare plant surveys and ecological studies, hydrological studies and the development of management plans for catchments around the Western Cape. SAEON now houses the archive of data collected by the Jonkershoek Forestry Research Center, which was originally held by the Council for Scientific and Industrial Research (CSIR).

    Authors: Ertaş, Cemal;

    Ahlat, Doğu Anadolu Bölges'inde patates tarımının en fazla yapıldığı yerlerin başında gelmektedir. Bu çalışmanın amacı; Ahlat'ta üretimi en fazla yapılan Granola patates çeşidinde, toprak ve yaprak analizleriyle verimliliğin ve bitki beslenme durumunun belirlenmesidir. Bu amaçla, Ahlat ilçesine bağlı patates üretiminin en fazla yapıldığı 10 farklı köy/mahalleden (Güzelsu, Kırklar, İkikubbe, Harabeşehir, Taşharman, Saray, Yıldızlar, Orta, Kurtuluş ve Kültür) ve her köy/mahalleden 4 çiftçi tarlası olmak üzere toplam 40 patates tarlasından toprak ve bitki örnekleri alınmıştır. Alınan toprak örnekleriyle yapılan analiz sonuçlarına göre; toprak örnekleri genel olarak, tınlı bünyede, organik madde miktarları düşük, (% 0.39-1.90) tuzluluk problemi olmayan, nötr-hafif asidik reaksiyonda (5.46-7.34) ve kireç miktarı bakımından (% 1.18-2.36) kireçli gruba dahildir. Denemeye alınan toprak örneklerinin % 88'inde yarayışlı P miktarı yeterli-fazla, % 98'inde değişebilir K miktarı yeterli, değişebilir Ca miktarı örneklerin % 60'ında yeterli ve % 40'ında düşük ve değişebilir Mg miktarı % 85 örnekte yeterli bulunmuştur. Toprakta DTPA ile ekstrakte edilebilir Fe, Zn ve Cu içeriklerinin genel olarak yeterli ve yüksek olduğu belirlenirken, DTPA ile ekstrakte edilebilen Mn içeriğinin toprakların % 58'inde yeterli ve % 42'sinde düşük olduğu belirlenmiştir. Yaprak analiz sonuçlarına göre; genel olarak yaprak N, P, Ca, Fe, Mn, Cu miktarları yeterli bulunurken, K, Mg ve Zn miktarları düşük bulunmuştur. Toprak analiz sonuçlarına göre; toprağa organik gübre ilavesinin patates yetiştiriciliği için faydalı olacağı kanaatine varılmıştır. Ayrıca, toprakta yeterli olmasına rağmen, bitkide K, Mg ve Zn miktarlarının düşük olması uygulanan azot ve fosforlu gübre düzeylerinin yüksekliğinden kaynaklanan antagonistik bir ilişkilerin varlığını göstermektedir. Ahlat is taken an important place among places which are cultivated potatoes in Eastern Anatolia. The aim of the study is to determine status of the fertility and plant nutrition through soil and leaf analysis of the most produced potatoes `Granola` in Ahlat. For this purpose, soil and plant samples were taken 40 potato fields in total; 10 different villages and neighborhoods (Güzelsu, Kırklar, İkikubbe, Harabeşehir, Taşharman, Saray, Yıldızlar, Orta, Kurtuluş, Kültür) and 4 farmer fields from each places. Productivity and various nutrient elements were analyzed by using these soil and plant samples. According to the results of the soil samples are generally determined in the group of loamy texture, low amount of organic matters (0.39-1.90%), no salinity problems, neutral- slightly acidic reaction (5.46-7.34) lime according the lime content (1.18-2.36 %). 88% of the sample soils in the resarch was found sufficient-excess for available P amount; 98 % of the sample soils was found sufficient for exchangable K amount. Also 60 % of the sample soils was found sufficient for exchangable Ca amount and 85 % of the sample soils was found sufficient for exchangable Mg amount. The amount of DTPA Mn was found sufficient in 58 % and low in 42 % of the soils while the amount of Fe, Zn and Cu extractable with DTPA in the soil was determined sufficient high. According to the results of the leaf analysis; N, P, Ca, Fe, Mn and Cu amounts of the leaf were found sufficient; K, Mg and Zn amount of the leaf was fount low. According to the results of the soil analysis, it can be said that the organic fertilizer addition would be benefical. Also, although they are sufficient in the soil, low amount of K, Mg and Zn in the plant shows antagonistic relationship between high amounts of nitrogen and phosphorus fertilizer applied. 66

    Up-to-date information on soil properties and the ability to track changes in soil properties over time are critical for improving multiple decisions on soil security at various scales, ranging from global climate change modeling and policy to national level environmental and development planning, to farm and field level resource management. Diffuse reflectance infrared spectroscopy has become an indispensable laboratory tool for the rapid estimation of numerous soil properties to support various soil mapping, soil monitoring, and soil testing applications. Recent advances in hardware technology have enabled the development of handheld sensors with similar performance specifications as laboratory-grade near-infrared (NIR) spectrometers. Here, we've compiled a hand-held NIR spectral library (1350-2550 nm) using the NeoSpectra Handheld NIR Analyzer developed by Si-Ware. Each scanner is fitted with Fourier-Transform technology based on the semiconductor Micro Electromechanical Systems (MEMS) manufacturing technique, promising accuracy, and consistency between devices. This library includes 2,106 distinct mineral soil samples scanned across 9 of these portable low-cost NIR spectrometers (indicated by serial no). 2,016 of these soil samples were selected to represent the diversity of mineral soils found in the United States, and 90 samples were selected across Ghana, Kenya, and Nigeria. 519 of the US samples were selected and scanned by Woodwell Climate Research Center. These samples were queried from the USDA NRCS NSSC-KSSL Soil Archives as having a complete set of eight measured properties (TC, OC, TN, CEC, pH, clay, sand, and silt). They were stratified based on the major horizon and taxonomic order, omitting the categories with less than 500 samples. Three percent of each stratum (i.e., a combination of major horizon and taxonomic order) was then randomly selected as the final subset retrieved from KSSL's physical soil archive as 2-mm sieved samples. The remaining 1,604 US samples were queried from the USDA NRCS NSSC-KSSL Soil Archives by the University of Nebraska - Lincoln to meet the following criteria: Lower depth <= 30 cm, pH range 4.0 to 9.5, Organic carbon <10%, Greater than lower detection limits, Actual physical samples available in the archive, Samples collected and analyzed from 2001 onwards, Samples having complete analyses for high-priority properties (Sand, Silt, Clay, CEC, Exchangeable Ca, Exchangeable Mg, Exchangeable K, Exchangeable Na, CaCO3, OC, TN), & MIR scanned. All samples were scanned dry 2mm sieved. ~20g of sample was added to a plastic weighing boat where the NeoSpectra scanner would be placed down to make direct contact with the soil surface. The scanner was gently moved across the surface of the sample as 6 replicate scans were taken. These replicates were then averaged so that there is one spectra per sample per scanner in the resulting database. The repository contains: Neospectra_database_column_names.csv: describes the variables (columns) of site and soil data, and the range of NIR and MIR spectra. Both Neospectra_WoodwellKSSL_avg and Neospectra_WoodwellKSSL_reps share the same columns. The CSV is composed of the file name, column name, type, example, and description with measurement unit. Neospectra_project_summary.txt: the summary of the project with purpose, the origin of soil samples, instrumentation, and brief SOP. Neospectra_WoodwellKSSL_avg_MIR.csv: the equivalent MIR spectra of neospectra samples' list that was fetched from the KSSL database and formatted to the OSSL specifications. Neospectra_WoodwellKSSL_avg_soil+site+NIR.csv: soil, site, and Neospectra's NIR. Each row contains the averaged spectra for a given scanner and soil sample (1 spectra per scanner per soil sample). Soil and site info is filled within the same soil sample. Neospectra_WoodwellKSSL_reps_soil+site+NIR.csv: soil, site, and Neospectra's NIR. Each row contains one replicated spectra of a given scanner (6 repeats per scanner per soil sample). Soil and site info is filled within the same soil sample. We thank the USDA NRCS National Soil Survey Center for providing access to their soil archives and for continuing to promote the use of soil spectroscopy. This project was funded by USDA National Institute of Food and Agriculture Award # 2020-67021-32467; USDA National Institute of Food and Agriculture Award # 2018-67007-28529; Woodwell Fund for Climate Solutions; and Foodshot Global.

    An assessment of soil nutrient status based on farmers’ samples was carried out in the Capricorn, Sekhukhune, and Waterberg Districts of the Limpopo Province of South Africa. A total of 336 soil samples were collected and analysed for pH, phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg). The results showed that the pH of more than 80% of the submitted soil samples was suitable for the production of most field crops ,while less than 20% required liming to make them productive. Phosphorus levels were very low (<8 mg kg-1), with most soils (≥95%) needing P fertilisation to improve crop yields. Potassium was adequate (>250 mg kg-1) for most districts' crops. Between 70% and 74% of soils from Sekhukhune and Waterberg Districts were deficient in Ca (<200 mg kg-1). Magnesium was adequate (>300 mg kg-1) in more than 60% of the analysed samples. Apart from soil pH, all soil properties showed a high degree of variability across all districts. Further studies are needed to investigate the role of field management, crop rotation, field position in the landscape, lithology, and socioeconomic conditions of the farmer on the observed trends of soil nutrients.

  • Authors: Jonkershoek Forestry Research Center;

    This is a scanned copy of a soil analysis report in Kogelberg, site 3418BD, including a map. The Jonkershoek Forestry Research Center (part of the former South African Forestry Research Institute) was established in 1935 at Jonkershoek, near Stellenbosch, under the directorship of Dr C. L. Wicht. The initial aim was to determine how forestry activities in state plantations would affect climate, water conservation and erosion, and was later expanded to include studies of fynbos ecology, fire and alien species. Studies from the 1930s to the early 1990s saw the accumulation of a large amount of data dealing with fire experiments, detailed vegetation plot surveys, rare plant surveys and ecological studies, hydrological studies and the development of management plans for catchments around the Western Cape. SAEON now houses the archive of data collected by the Jonkershoek Forestry Research Center, which was originally held by the Council for Scientific and Industrial Research (CSIR).

    Authors: Ertaş, Cemal;

    Ahlat, Doğu Anadolu Bölges'inde patates tarımının en fazla yapıldığı yerlerin başında gelmektedir. Bu çalışmanın amacı; Ahlat'ta üretimi en fazla yapılan Granola patates çeşidinde, toprak ve yaprak analizleriyle verimliliğin ve bitki beslenme durumunun belirlenmesidir. Bu amaçla, Ahlat ilçesine bağlı patates üretiminin en fazla yapıldığı 10 farklı köy/mahalleden (Güzelsu, Kırklar, İkikubbe, Harabeşehir, Taşharman, Saray, Yıldızlar, Orta, Kurtuluş ve Kültür) ve her köy/mahalleden 4 çiftçi tarlası olmak üzere toplam 40 patates tarlasından toprak ve bitki örnekleri alınmıştır. Alınan toprak örnekleriyle yapılan analiz sonuçlarına göre; toprak örnekleri genel olarak, tınlı bünyede, organik madde miktarları düşük, (% 0.39-1.90) tuzluluk problemi olmayan, nötr-hafif asidik reaksiyonda (5.46-7.34) ve kireç miktarı bakımından (% 1.18-2.36) kireçli gruba dahildir. Denemeye alınan toprak örneklerinin % 88'inde yarayışlı P miktarı yeterli-fazla, % 98'inde değişebilir K miktarı yeterli, değişebilir Ca miktarı örneklerin % 60'ında yeterli ve % 40'ında düşük ve değişebilir Mg miktarı % 85 örnekte yeterli bulunmuştur. Toprakta DTPA ile ekstrakte edilebilir Fe, Zn ve Cu içeriklerinin genel olarak yeterli ve yüksek olduğu belirlenirken, DTPA ile ekstrakte edilebilen Mn içeriğinin toprakların % 58'inde yeterli ve % 42'sinde düşük olduğu belirlenmiştir. Yaprak analiz sonuçlarına göre; genel olarak yaprak N, P, Ca, Fe, Mn, Cu miktarları yeterli bulunurken, K, Mg ve Zn miktarları düşük bulunmuştur. Toprak analiz sonuçlarına göre; toprağa organik gübre ilavesinin patates yetiştiriciliği için faydalı olacağı kanaatine varılmıştır. Ayrıca, toprakta yeterli olmasına rağmen, bitkide K, Mg ve Zn miktarlarının düşük olması uygulanan azot ve fosforlu gübre düzeylerinin yüksekliğinden kaynaklanan antagonistik bir ilişkilerin varlığını göstermektedir. Ahlat is taken an important place among places which are cultivated potatoes in Eastern Anatolia. The aim of the study is to determine status of the fertility and plant nutrition through soil and leaf analysis of the most produced potatoes `Granola` in Ahlat. For this purpose, soil and plant samples were taken 40 potato fields in total; 10 different villages and neighborhoods (Güzelsu, Kırklar, İkikubbe, Harabeşehir, Taşharman, Saray, Yıldızlar, Orta, Kurtuluş, Kültür) and 4 farmer fields from each places. Productivity and various nutrient elements were analyzed by using these soil and plant samples. According to the results of the soil samples are generally determined in the group of loamy texture, low amount of organic matters (0.39-1.90%), no salinity problems, neutral- slightly acidic reaction (5.46-7.34) lime according the lime content (1.18-2.36 %). 88% of the sample soils in the resarch was found sufficient-excess for available P amount; 98 % of the sample soils was found sufficient for exchangable K amount. Also 60 % of the sample soils was found sufficient for exchangable Ca amount and 85 % of the sample soils was found sufficient for exchangable Mg amount. The amount of DTPA Mn was found sufficient in 58 % and low in 42 % of the soils while the amount of Fe, Zn and Cu extractable with DTPA in the soil was determined sufficient high. According to the results of the leaf analysis; N, P, Ca, Fe, Mn and Cu amounts of the leaf were found sufficient; K, Mg and Zn amount of the leaf was fount low. According to the results of the soil analysis, it can be said that the organic fertilizer addition would be benefical. Also, although they are sufficient in the soil, low amount of K, Mg and Zn in the plant shows antagonistic relationship between high amounts of nitrogen and phosphorus fertilizer applied. 66
