Abstract

After green revolution era India agriculture encountered the several problems of soil health, slightly stagnation of food grain production, reduce the ecological resilance etc. resulting overall declining in the system productivity. Integrated application of nutrients for rice-wheat (RW) and agroforestry system is necessary for maintaining soil properties. In sequence to assess the impact of various nutrient management approaches on RW and agroforestry field experiment was conducted during 2016-17 and 2017-18 in which four treatments were taken in an ongoing Long Term Fertilizer Experiment (LTFE), and two treatments from Agroforestry system i.e. Poplar and Eucalyptus based agroforestry systems. Results showed that the organic soil carbon, nitrogen, phosphorus and potassium content increased by 92.41 and 97.60%, 0.396 and 0.390%, 56.34% and 54.84%, 60.39 and 65.06% and 31.99 and 28.68%, respectively over 100% NPK application in R-W cropping system for surface soil in both kharif and ra

Conclusion

Continuous application of inorganic fertilizers alone or integration with any of the organics did not influence soil pH. The inorganic fertilizers with organic manure maintained or improved available N, P, K and soil organic carbon content in comparison to application of NPK fertilizers alone in both the cropping system i.e. R-W and agroforestry based cropping system. It is concluded that continuous application of inorganic fertilizers alone could not sustain the soil fertility status and productivity. Thus, integrated nutrient management in continuous cropping system and agroforestry based cropping systems proved effective for sustainability of soil on long term basis.
