Important Agriculture Statistics • Agro climatic zone 11 • Net cultivable area 150.75 • Fallow land 11.55 • Area sown : Kharif 118.59 • Rabi 104.32 • Double cropped area 72.16 • Cropping Intensity 148% • Area under irrigation 36.5% • Rainfed 63.5% • No. of Land holdings 79.08 lakhs • Spall and marginal farmers 53.47 lakhs (68%) • Fertilizer Consumption 80.19
Present Status of Soil Testing Labs in M.P. • There are 24 state Govt., 26 Mandi Board and 25 SAUs [Total 75] in working condition. • Maximum capacity of Departmental lab to analyze 10,000 soil sample per lab in a year . • From 2009 to till now 16.80 Lakh. Soil health cards has been distributed. • The status of organic carbon found low to medium. • The status of soil PH and EC mostly normal • Consumption of N P K fertilizer in the year 2011-12 is 88.28, in the year 2012-13 is 83.20 and in the year 2013-14 is 80.19 kg. per hectare.

Awareness programs for farmers to maintain soil health and increasing the soil fertility • Organic farmer field school 45420 farmers benefited during 12-13 & 13-14. • Exposure tour out of state and within state - 10,140 farmer benefited during last two year. • Conduction of organic farming training – 26,100 farmers benefited during last two year .
Application of organic matter and micronutrients to maintain the soil health • To prepare 16,655 vermicompost to promote for organic farming during last two year. • 21436 farmers are using biogas slurry during last two year. • Use of Zinc sulphate in 518979 hectares during last two year. • Use of gypsum in 116852 hectares during last two year.
Proposed work to maintain soil health in NMSA • Setting of 27 new soil testing lab is proposed. • Proposal for strengthening of 24 existing departmental soil testing labs. • Proposal for strengthening of 4 existing fertilizer quality control lab. • Proposal for promotion of organic farming and INM. • Project for promotion of micronutrient to improve the status of Zn in soil of M.P. • Establishment of organic agriculture research and teaching department. • Package and practices for different cropping systems under organic farming.
Action to be taken for better Soil health and NUE • Soil testing and scientifically sound management decisions about fertilizer. • Requirement and given recommendations. • • Increase yield by providing balance amount of nutrients. • • Base N P and K application rates on soil test and yield goals. • • Increase contribution of legumes, manures, crop residues and other organic wastes • • Synchronize application with crop demand and utilization of fertilizer nutrients. • • Use slow release N fertilizers and nitrification inhibitors to reduce leaching. • • Schedule irrigation to minimize leaching losses. • • Diversify crop rotations to include crops that utilize residual nitrogen. • • Place the fertilizer at right depth, right amount, right time with right source. • • Use variable fertilizer application rates in variable fertility soils.
Practices of N application for better soil health and NUE • Band placement reduces immobilization • Deep placement in reduced zone improves N use efficiency in rice • Band placement can prevent ammonia volatilization losses by 15-20% in wheat. • Where soil and environmental conditions favour NO3 loss, nitrification • inhibitors will increase N use efficiency. • Fertilizers like Neem coated urea are better suited for transplanted rice • Urease inhibitors have proven effective where ammonia volatilization is a problem especially when urea is surface applied. • Urea super granules when placed as basal have shown to increase N use efficiency by 6-30% compared to prilled urea.
Practices of P & K application for Better Soil Health and NUE • Placement/drilling to optimize use efficiency • • Deep placed P + restricted irrigation is on par with P broadcast unrestricted irrigation • • Most efficient when P is banded with or near the seed • • Band placement reduces surface contact between the soil and fertilizer • • Seed placed P & K is most beneficial when soil test P & K is low and soil moisture is • optimum • • Refine animal feed ration • • Use feed additives to increase animal absorption of P • • Move manure from surplus to deficit areas • • Apply conservation practices such as reduced tillage, buffer strips and cover crops. • In high rainfall areas with coarse texture split application of K gives higher efficiency • • In a sandy loam soil, split application resulted in a higher yield.
Practices for recycling manure nutrients • Soil test once in three years for recommending INM • • Develop a baseline for manure nutrient content and quality • • Prioritize manure application in fields testing low in P and K • • Apply manure before cereal rather than legume • • Calculate N credit from legumes and other N sources • • Apply manure uniformly to cover the entire field • • Keep records of what, when, where, and how much manure is applied to fields • • Limit manure application on untilled fields • • Avoid manure application to sloping or eroded soils
Manage organic C for better soil health • Residue retention on soil • Integrated nutrient management • Avoiding residue burning
