Impact of integrated farming system on residue recycling, nutrient budgeting and soil health

In this study, the effects of integrated farming system on residue recycling and soil quality in rice-based systems have been examined. The effective nutrient budget for nitrogen was found higher with rice-fishpoultry- cowpea negative values were obtained rice-chili rice-baby corn systems. However, budgets phosphorus potassium all these cropping results indicated that, about ten tonnes organic matter recycled, major share from dairy unit (~52%) form dung cow urine. Total internal supply due to estimated at 55 kg nitrogen, 17 76 potassium, which is equivalent 118 urea, 106 single super phosphate 126 muriate potash, thus reduction cost inputs. rice+fish+poultry-cowpea system, indices showed values, improvement fertility availability poultry manure, plankton production, continuous fish activity. current study confirmed that available N, DHA, Zn, B Fe as key indicators under humid tropics west coast India, greatly influence functions productivity. conclusively reveals integration dairy, fishery, components diversified coastal lowland ecosystem essential improve use efficiency enrichment fertility.
