Effects of irrigated cover crop cultivation period on common bean and soybean yield
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 ...

Crop and soil responses to 24 years of wheat residue removal and tillage
Abstract Retaining crop residue on agricultural land mitigates soil erosion and conserves nutrients, but its removal generates a valuable commodity for competing uses in agriculture and industry. Understanding long‐term effects of crop residue removal on crop performance and soil condition is essential to guide management decisions regarding ...

Implementing potential climate‐smart practices through diverse partnerships
Climate change is one of the greatest threats to society, negatively impacting agriculture and crop yields. Globally, agriculture is also one of the largest greenhouse gas (GHG) emitting sectors. Climate‐smart practices that are developed through diverse partnerships with scientists and practitioners are needed to decrease GHG emissions. We implemented
