Residue recycling options and their implications for sustainable nitrogen management in rice–wheat agroecosystems

Ecological Processes 2023年第4期12卷 91-109页

Background In the Indo-Gangetic Plain, rice–wheat is the most extensively practiced crop rotation. the escalating issue of crop residue burning, particularly rice straw, and the necessity to lower the exorbitant expenses associated with fertilizer inputs stand out as significant challenges for farmers in the region. A well-suited integrated nutrient management（INM） strategy that focuses on recycling crop residues can serve as a solution to address these issues. Such a strategy not only mitigates air pollution resulting from residue burning but also helps combat water pollution due to nitrate losses from agroecosystems. Field experiments were used to evaluate the suitability of eight INM-modules that included various combinations of inorganic fertilizer rates（50%, 100%, 150% of recommended dose）, crop residues（wheat and rice stubble retention at 30 cm standing stubble equivalent to 1/3 the straw yield）, rice straw compost（RSC）, farmyard manure（FYM）, and green manuring（GM）, compared to 100% recommended dose of fertilizers（F） and no fertilizer *** there was a considerable improvement in nitrogen mineralization, grain yields, and nitrogen use efficiency under GM + RSC-F50 and GM + FYM-F50. these INM modules would permit a 50% reduction in the use of chemical fertilizers. there was a little yield penalty with in situ rice residue incorporation at 100% F; however, this could be overcome with 150% F fertilizer application. In situ retention of wheat straw with a full application of fertilizer resulted in steadily rising crop yields over time. Changes in the redox potential, soil p H, and soil organic carbon best accounted for the observed trajectories in nitrogen use *** the most promising INM modules for adoption by farmers in the Indo-Gangetic Plain to judiciously use crop residues and curtail chemical fertilizer inputs are green manuring with Sesbania aculeata + rice straw compost at 5 t ha-1+ only 50% of recommended dose of fertilizers
