Learnings from Long-term Experiments: Towards Regenerative Agriculture - B.S. Dwivedi - ICAR-National Bureau of Soil Survey and Land Use Planning

• The main aim of RA is to improve the soil health or to restore degraded soil, which symbiotically enhances the quality of water, vegetation and land-productivity. [...] • Generally set-up to study the effect of crop rotations, monocultures, organic and mineral fertilization, application of micronutrients, and response of new crop varieties. [...] • More changes were introduced in 1970s and thereafter in management, cropping, Mean long-term yields of winter wheat type of fertilizers, and crop varieties to (1852–2016) showing selected treatments, ensure that the experiments remain important changes in management and cultivars grown. [...] • Possibilities to be explored for need-based bifurcation of plots and expansion of the layout to adjoining uncultivated area. [...] ICAR-NBSS&LUP Path Ahead to strengthen soil health management towards RA • Greater emphasis on organics other than FYM e.g., enriched composts, crop diversification with legumes, CR and waste recycling, industrial by-products… • Develop/refine nutrient management protocols for RA and IFS based on nutrient fluxes and flows • Establish mechanized composting units in rural areas to promote availabili.
