Annually 500 M t organic wastes are produced in India from the agriculture sector. Transportation of bulky organic manures for centralized collection, processing and distribution to farms is cost prohibitive. Hence, recycling of agricultural wastes using vermicompost technology at the farm level is a practical way of managing agriwaste for meeting the plant nutrient requirement. Our experience with a 1.584 ha farm for three years (2015-2016 to 2017-2018) revealed that 8.1 t vermicompost was produced in three batches from 24 t agriwastes produced within the farm area. The system productivity by recycling these farm generated agriwastes and run-off water was 18.05 t (≈11.4 t ha-1) rice equivalent yield which was higher by 2.6 times as compared to rice fallow (4.46 t ha-1). Also, the net return from this system (Indian rupees 70141 ha-1) was higher by 2.3 times, after considering the fixed cost towards construction of a water recycling pond. An increase in carbon stock in soil for the four years study period was 0.66 Mg ha-1 year-1 with the agriwaste recycling system under organic nutrition. For the inorganic fertilizer plot, the increase in carbon stock was 0.53 Mg ha-1 year-1. A decrease in bulk density from 1.56 to 1.46 Mg m-3, increase in water holding capacity from 0.43 to 0.52 cm3 cm-3 and increase in available P and K content in soil from 38.0 and 174.7 kg ha-1 to 45.8 and 186.5 kg ha-1, respectively, were noted. Thus, recycling of agricultural waste at the farm level is useful in improving soil health and crop productivity.

通过自力更生的耕作系统在农场一级进行可持续的农业废料管理。

印度每年从农业部门生产5亿吨有机废物。将大块有机肥料集中收集，加工和分配到农场的运输成本很高。因此，在农场一级使用vercompostcompost技术回收农业废物是管理农业废料以满足植物营养需求的实用方法。我们在一个1.584公顷的农场中三年（2015-2016至2017-2018）的经验表明，在该农场区域内生产的24吨农业废料中，分三批生产了8.1吨ver麦。循环利用这些农场产生的农业废料和流失水的系统生产率为18.05 t（≈11.4t ha-1）水稻当量产量，比休闲稻（4.46 t ha-1）高2.6倍。也，考虑到建造回用水池的固定成本后，该系统的净收益（印度卢比70141 ha-1）提高了2.3倍。在有机营养条件下的农业废料回收系统的作用下，四年研究期的土壤碳储量增加了0.66 Mg ha-1 year-1。对于无机肥田，碳储量增加了0.53 Mg ha-1 year-1。容重从1.56 Mg m-3降低到1.46 Mg m-3，持水量从0.43 cm3 cm-3增加到0.52 cm3 cm-3，土壤中的有效磷和钾含量从38.0和174.7 kg ha-1增加到45.8和186.5 kg分别指出ha-1。因此，在农场一级回收农业废弃物对于改善土壤健康和提高作物生产率很有用。在有机营养条件下的农业废料回收系统下，四年研究期的土壤碳储量增加了0.66 Mg ha-1 year-1。对于无机肥田，碳储量增加了0.53 Mg ha-1 year-1。容重从1.56 Mg m-3降低到1.46 Mg m-3，持水量从0.43 cm3 cm-3增加到0.52 cm3 cm-3，土壤中的有效磷和钾含量从38.0和174.7 kg ha-1增加到45.8和186.5 kg分别指出ha-1。因此，在农场一级回收农业废弃物对于改善土壤健康和提高作物生产率很有用。在有机营养条件下的农业废料回收系统下，四年研究期的土壤碳储量增加了0.66 Mg ha-1 year-1。对于无机肥田，碳储量增加了0.53 Mg ha-1 year-1。容重从1.56 Mg m-3降低到1.46 Mg m-3，持水量从0.43 cm3 cm-3增加到0.52 cm3 cm-3，土壤中的有效磷和钾含量从38.0和174.7 kg ha-1增加到45.8和186.5 kg分别指出ha-1。因此，在农场一级回收农业废弃物对于改善土壤健康和提高作物生产率很有用。容重从1.56 Mg m-3降低到1.46 Mg m-3，持水量从0.43 cm3 cm-3增加到0.52 cm3 cm-3，土壤中的有效磷和钾含量从38.0和174.7 kg ha-1增加到45.8和186.5 kg分别指出ha-1。因此，在农场一级回收农业废弃物对于改善土壤健康和提高作物生产率很有用。容重从1.56 Mg m-3降低到1.46 Mg m-3，持水量从0.43 cm3 cm-3增加到0.52 cm3 cm-3，土壤中的有效磷和钾含量从38.0和174.7 kg ha-1增加到45.8和186.5 kg分别指出ha-1。因此，在农场一级回收农业废弃物对于改善土壤健康和提高作物生产率很有用。
