Balanced nutrition based on soil test value is the key to sustain and improve soil productivity. Integrated management of organic, secondary and micronutrient inputs along with inorganic fertilizers in soils is required to prevent decline in soil fertility, crop productivity and sustainability. In present investigation is conducted to study the influence of farmyard manure (FYM), sulphur and zinc along with inorganic NPK fertilizers either alone or in combination on the nutrient availability in soil. Results revealed that use of FYM increased the organic carbon content and availability of nutrients over soil alone and soil treated with only inorganic fertilizers. Results further revealed that the beneficial effects of FYM got enhanced when it is applied along with S and Zn.

Restoration of soil has been identified as the option; to ensure crop sustainability. However, as per Trophobiosis Theory of French Scientist F. Chaboussou, focus on development of healthy plants is necessary to abate pest and disease invasion so as to ensure sustained crop performance, even under unfavorable environmental conditions. The present study, in randomized block design with green gram as test crop; was undertaken in Krishi Vigyan Kendra (Howrah, West Bengal) to evaluate the effectiveness of Inhana Rational Farming (IRF) Technology towards crop yield and soil quality development under different sustainable models viz. organic cultivation, integrated soil with organic crop management and non-chemical crop management; as compared to conventional farming practice. Highest yield was recorded under organic (933 kg ha ). The results were well corroborated with the plant development index obtained under these treatments. Favorable trend of soil quality under sustainable models especially in terms of microbial properties indicated the role of quality compost towards speedy rejuvenation of soil dynamics. The study indicated that reduction of synthetic fertilizers and qualitative management of soil is essential to restrict yield decline. However, plant management shall be prerequisite for ensuring crop sustainability without any time lag and under the changing climatic patterns. In this respect the potential of IRF Technology has been well accounted.
