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

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 ...

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 ...

Does rotational bale grazing affect the distribution of soil nutrients across pastures?

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Rotational bale grazing (RBG), the strategic feeding of round hay bales directly on pasture with controlled access, offers an alternative to continuous winter hay feeding in a single paddock. This study evaluated RBG's potential to redistribute nutrients by increasing soil concentrations in field areas with lower phosphorus (P) and potassium ...

Comparing the effects of soil test interpretations for P and K on a creeping bentgrass putting green

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Soil testing provides golf course superintendents with the information needed to apply fertilizers at optimal rates, thereby avoiding nutrient deficiencies and unnecessary applications. However, nutrient rate recommendations vary depending on how soil test results are interpreted.
