Net mineralizable soil phosphorus cannot be measured by non‐isotopic approaches

Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Abstract While radioisotopic pool dilution is widely regarded as the most reliable method for estimating soil phosphorus mineralization (Pmin), high costs, low throughput, and safety requirements limit its use. We evaluated the potential of non‐radioisotopic approaches to estimating net Pmin by difference before and after aerobic incubation, analogous ...

Analyzing soil-available phosphorus by the Mehlich-3 extraction method to recommend a phosphorus fertilizer application rate for maize production in northern Mozambique

Plant Production Science, 2019
The available phosphorus (P) in soil is a major limiting factor for maize productivity in the Nacala corridor, Mozambique. In this study, soils were collected from three representative sites, Ribaue, Nampula, and Nacala, in the area, and each was used ...

Fósforo disponível determinado por lâmina de resina enterrada Soil phosphorus availability determined by anionic-exchange resin membrane in the soil

Revista Brasileira de Ciência do Solo, 2009
O uso de lâminas de resina de troca aniônica enterradas no solo permite simular, em parte, o comportamento das raízes das plantas em relação à absorção de P. Essa técnica, utilizada diretamente no solo nas mesmas condições que se cultivam as plantas, sem

Spatiotemporal changes in soil chemical properties when cover crops are integrated into raised, stale seedbed corn production systems

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Commercial row crop production in the midsouthern United States is characterized by extensive application of inorganic soil inputs and management practices that contribute to degraded soil health. This study was conducted to determine if cover crops affect spatial or temporal changes in soil chemical properties in a raised, stale seedbed ...

Corn response to broiler litter total cleanout frequency

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Broiler (Gallus gallus domesticus) litter is a valuable nutrient source for corn (Zea mays L.) production in the southeastern United States; however, differences in total cleanout frequency of broiler houses may influence the agronomic value of broiler litter. A 3‐year field study was established on Decatur silt loam and Malbis sandy clay loam

Cover crops and nitrogen rates: Impacts on no‐till corn and soil health in Louisiana

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Use of cover cropping systems to improve soil health is still limited in Louisiana. This study aimed to examine the interaction between cover crops and nitrogen (N) fertilizer rates on crop yield, soil chemical, and biological properties. Winter cover crop treatments, including legumes, a grass and brassica, and a fallow control, were combined

Soil properties and pH of the extractors influence extraction and availability P in alkaline soils from the São Francisco Valley, Brazil

Revista Brasileira de Ciência do Solo
Phosphorus (P) is one of the most used nutrients in agriculture due to its high degree of interaction with the soil. It is susceptible to calcium precipitation in poorly weathered and alkaline soils, such as those in the Brazilian Semi-Arid region ...

Changes in soil test phosphorus are not predictable using fertilizer input and crop removal

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Volatile fertilizer prices have led to many producers and researchers exploring different immobile nutrient stratagems to increase the efficiency of fertilizer applications, leading to greater economic return. While many nutrient recommendations are based upon a soil test for that one season, for immobile nutrients such as phosphorus (P ...
