- ... Converting straw to biochar (BC) followed by successive application to soil has been increasingly suggested as a multi-win approach for soil fertility improvement, carbon (C) sequestration and efficient disposal of straw residues in intensive cropping agroecosystems. However, different soil types response differently in terms of crop growth and non-CO2 greenhouse gas (GHG) emissions after BC appli ...

- ... Achieving reductions in nitrogen (N) losses and carbon (C) emissions without enduring a yield penalty is an environmental and economic challenge in sustainable rice production. The use of legumes as a winter crop in rice rotations may provide environmental benefits by reducing synthetic N inputs, yet few studies have integrated long-term field measurements of cropping system N and C dynamics with ...
