Management practices for soil carbon sequestration
About 336 million tonnes of crop residues are produced per year which can supply about 5.1 million tonnes of K in addition to organic matter.
Balanced fertilisation beyond NPK- - - ?
S, Zn, B……
The K balance of Punjab, Haryana and other Northern Indian states appears to be worst in the country as the K consumption is very low.
Deficiencies of S, Zn and B has become critical
• Application of 5 kg Zn/ha is sufficient on alluvial, red and
• 10 kg Zn/ha is optimum on Vertisols.
• 1-1.5 kg B/ha to alternate crops for oilseed based cropping
• Regular application of FYM 8-10 t/ha can control
• When 4-5 t/ha FYM is applied, Zn rate can be reduced by
Mining of nutrients from soil
Projected Food Grain Production, Fertilizer Demand, likely Consumption and Gap
•Integrated Nutrient Management
• Balanced Fertilization through Inorganic
Fortified and Coated Fertilisers
Customised and 100% Water soluble fertilisers
• Soil Test Based Fertilizer Recommendations
• Improved Nutrient Management Practices
Integrated nutrient management (INM) aims at achieving efficient use of chemical fertilizers in conjunction with organic manures and biofertilizers and improves soil health, crop yields and profitability
Need to augment supplies of organic manures, fortified, coated & customized fertilizers supplying secondary and micronutrients, biofertilizers and soil amendments to have INM on a sound footing.

Fertilisers policy was modified to create an environment to motivate industry towards development of new products based on soil and crop requirement.
To increase the use and availability of SSP (16% P2O5, 11% S) as an alternative source of P, the GOI modified its specifications
Phospogypsum, a by-product of fertilizer industry containing 16% S and 21%Ca, a potential source of S and Ca has been incorporated in FCO. About 7MT of phosphogypsum generated per annum has a potential to supply 1 mt of S and 1.4 mt of Ca
The neem coated urea , a slow release fertilizer was included under Schedule- I Part –A of the Fertilizer Control Order.
To encourage the balanced fertilizer use, the basket of complex fertilizers is broadened and some new complex fertilisers have been incorporated in FCO
Production (thousand tonnes)
Nutrients needs of Indian agriculture are now bigger and more wider (balanced fertiliser beyond NPK)
The challenge ahead is to precisely monitor key soil health parameters and adopt integrated nutrient management practices that improve soil health
Ensure that nutrients are managed in a balanced and efficient manner
