Effects of irrigated cover crop cultivation period on common bean and soybean yield
Crop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.Abstract Cover crop inclusion is essential for improving soil management in tropical no till systems; however, the optimal duration of irrigated off‐season cultivation remains uncertain. This 3‐year field study evaluated nine cover crop species or mixtures and four cultivation periods (60, 75, 90, and 105 days) on biomass production, soil chemical ...

Soil carbon stock and physical attributes under land‐use chronosequence in the Brazilian Cerrado
Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.Abstract Land‐use changes impact soil physical quality and carbon stocks. Most studies evaluating the conversion of native Brazilian Cerrado to agriculture focus on surface soil layers (up to 40 cm), with fewer examining deeper layers (0–100 cm). This study assessed the impacts of different land‐use systems on soil physical attributes and soil organic ...
