Sub zone IV
� Low water retentive capacity of the soil particularly that of uplands.
� Late arrival and early cessation of monsoon and erratic and uneven distribution of rainfall
� Lack of safe disposal of runoff water during monsoon and water storage and moisture conservation practices for raising Rabi crops.
Drying of tanks and wells by February results in no Rabi crop production.

� Soil acidity is a limiting factor for crop production particularly for
legumes oil seeds, maize, wheat and vegetables etc. The problem of
acidity is likely to increase due to erosion of surface soil and use of only
nitrogenous fertilizers by the farmers.
� Based on the analysis of 12,823 soil samples of the 22 districts of � Based on the analysis of 12,823 soil samples of the 22 districts of
Jharkhand it was found that soils of about 49 per cent of the total
geographical area (TGA) of the state are extremely acidic to strongly
acidic (pH <5.5); about 36 per cent area suffering from moderate to
slight soil acidity (pH 5.6 to 6.5)
� soil acidity was the core problem in getting optimum agriculture
production.
Jharkhand soil in general, are low to very low in available phosphorus and sulphur,
medium in available nitrogen & potassium status and deficient in available boron.
� The organic carbon content of soils of about 47 per cent of TGA are low to medium
(<0.5% to 0.75%)
� Soils of majority area (about 70% of TGA) of the state have medium status of
available nitrogen (280 to 560 kg/ha) and about 19.6 per cent area have low
available N content (<280 kg/ha).
� Soils of about 66 per cent area are low (<10 kg/ha) in available phosphorous � Soils of about 66 per cent area are low (<10 kg/ha) in available phosphorous
content while about 28 per cent area are found to be medium (10 – 25 kg/ha) in
available P content.
� Most of the soils (about 51% of TGA) have medium potassium content and about
18 per cent are low (below 108 kg/ha) in available potassium content.
� Soils of about 38 per cent area are low (<10 mg/kg) whereas soils of about 31 per
cent are medium (10-20 mg/kg) in available sulphur content.

Soil degradation, diagnosis, conservation and
management
�For managing poor soil structure, residue incorporation and
mulching , manuring, and some forms of agro forestry, cover
cropping, contour ploughing, minimum tillage and efficient

considered ideal for indian soils, the present use ration of is wide
�The imbalance and low nutrient use has resulted in a wide gap
between crop removal and fertilizer application. Long term fertilizer
experiments in India have in general, showed that P and K status in
soil have gone down when only N was applied and soil become hard .

Strength
� Basic information on soil pH,Org.C,Avail.P&K,Texture are provided by STLs of the state
� State has STLs in each district,which caters to the need of soil health assessment. Besides University, need of soil health assessment. Besides University, KVKs and NGOs have soil testing facilities.
� Soil test based information is superior to Blanket recommendation.
� Farmers in general have idea of native soil health based on their ITKs(Indigenous Tech. Knowledge)
Weakness
� Most STLs in the state are poorly equipped in terms of building,tech. personnel, Instruments etc.
� No. of such Labs are meagre & this needs to be increased to meet the state needs.
� Soil test recommendations are not made for different � Soil test recommendations are not made for different crop yield targets.
� Functioning of Soil testing Labs is poor & there is lack of coordination among them.
� In general, soil testing is not a priority for farmers in the state, due to aforesaid reasons.
Opportunities
� Soil test data base for the state is essential for sustainable crop production through balanced input use.
� Soil Nutrient maps at district/block level will help in soil health planning.
� Soil health assessment must include Secondary & Micronutrients, � Soil health assessment must include Secondary & Micronutrients, beside major ones.
� Soil health assessment must be done with farmers as partners for greater benefits.
� Soil health assessment will improve Nutrient & water use efficiency by crops.
� New Concepts on soil test based nutrient use in crops, such as SSNM,STCR, IPNM etc. must be tested with large scale farmers field trials for higher profits from input use.
Threats
� Generalised soil testing is not of much use. It should be site specific & tuned to farmers need.
� Soil testing should be integrated with water use, crops& cropping systems, land holding & economic condition of farmers.condition of farmers.
� Without liberal support of State Govt.,this will not make much headway.
� Analytical methods used & interpretation of soil tests, determine the effectiveness of soil tests.
� Soil test reports often do not reach farmers in time.
Short term initiatives
� Soil sample collection should be GIS based and also land situation based. Areas under high value crops, area under intensive cropping should be priority areas.
� Ready reckoners for lime use based on Lime � Ready reckoners for lime use based on Lime requirements of soils to be available with STLs.
� Secondary & micronutrients analysis in STLs to be included.
� Soil health assessment done should indicate required input use for different yield targets.
Continued ------
� All facilities for infrastructure, equipments, personnel must be in place .
� Regular training of farmers, extension personnels, soil testing staff etc. must be provided.soil testing staff etc. must be provided.
� Quality of soil test needs improvements, based on periodic checking of samples & their analysis in University lab .
� All KVKs, ATMAs, NGOs must be linked under the soil health assessment programme.
Long Term Initiatives
� Emphasis to be laid on efficiency of input use based on soil tests under crops/cropping systems.
� Soil health information must be complete. This should help to manage problem soils, soil errosion, water resources use, better Nutrient recovery by crops, resources use, better Nutrient recovery by crops, sustaining Soil organic matter levels etc.
� Data interpretation ,data storage ,monitoring and follow-up mechanisms should be in place.
� Soil Nutrient Mapping must be done at Block Level for planning & execution purposes.
Continued ------
� Soil health indicators in each Agro-climatic zones need to be identified.
� Multi-nutrient soil tests should be developed in Research Labs for use by STLs.
� Soil health information should be digitized and communicated through IT-based services.
� Soil health information should be digitized and communicated through IT-based services.
� Adoption of Soil Test based Nutrient Use by majority of farmers should be the target. This will require regular interaction with all concerned and a mission mode implementation.
� To standardize soil health indicator for acid soil
� Management practice to overcome the issue of surface crusting , subsurface hardness , low rate of infiltration ,
� Termite is a big issue in acid soil .Crop residue left in the field further aggravate the termite population and may cause damage the crop . To get the benefit of crop cover cause damage the crop . To get the benefit of crop cover there is a need to do research on crop as well as termite population along with measures to control it .
� Identify farm implement for the farmers having land holding <50 decimal or 0.5 acre.
� Standardize the time and amount of crop residue incorporated in soil for getting better soil health.
� To develop rapid method of soil analysis for different physical ,Chemical and Biological parameters.
� Generate soil resource inventory data base for physical chemicalbiological and soil pathogen parameter under different land situationand suggest management practices to address the issue of soil health inJharkhand .
� Boron and Molybdenum is deficient in acid soil .In soil health indicatordue wattage has to be worked out .
� Calcium and Magnesium deficiency, and measures to overcome thesame needs to be addressed .
� Use of beneficial fungi needs to be workout .
� Control of soil born pathogen specially problem of wilt needs to beaddressed.
