Soil testing is an effective process to maintain sustainable soil health. Main reason of decreasing soil health is intensive cropping pattern & continuous use of imbalance fertilization. Due to this the quality & productivity of the crops adversely affected. Regular insufficiency of plant nutrients in soil creates so many problems in farmers field. Fertilizers recommendations for different crops based on the available plant nutrients in the soil resulting better yield. Soil fertility depends upon the fertilizer use on soil test basis (including pH & EC). Soil analysis is a valuable tool for farm as it determines the inputs required for efficient and economic production. A proper soil test will help ensure the application of enough manure & fertilizer to meet the requirements of the crop while taking advantage of the nutrients already present in the soil. Proper nutrition is essential for satisfactory crop growth and production and use of soil tests can help to determine the status of plant available nutrients to develop fertilizer recommendations to achieve optimum crop production. Efficient application of the correct types and amounts of fertilizers and manure for the supply of the nutrients is an important part of achieving profitable yields and minimizing environmental impacts.

KRIBHCO Krishi Pramarsh Kendra (KKPK) continues to provide free consultancy on farm-related issues through Kisan Helpline (Ph-0120-2535628 & E-mail: krishipramarsh@kribhco.net), propagated efficient and balanced use of fertilizer through providing farmers free of cost Soil Health Cards by testing including pH & EC more than 4.95 lakh soil samples in which 4.45 lakh soil samples for Macro-nutrients( %OC, P, K) and more than 49,000 soil samples for Micro-nutrients(Zn,Cu,Fe,Mn) collected from 16 states of the country. Soil samples collected from farmer’s field send through courier to KKPK for testing. All the soil health cards with results & recommendation send to farmers by e-mail through our Field Officers as well as farmers. The results are also uploaded regularly on KRIBHCO website for easy & prompt access by farmers. All the farmers get benefited by using balance fertilizer on soil test basis.

Why Soil Testing?

Soil testing is an effective process to maintain sustainable soil health. The main reason of decreasing soil health is intensive cropping pattern & continuous use of imbalance fertilization. Due to this the quality & productivity of the crops adversely affected. Regular insufficiency of plant nutrients in soil creates so many problems in farmers field. Fertilizers recommendations for different crops based on the available plant nutrients in the soil resulting better yield. Soil fertility depends upon the fertilizer use on soil test basis (including pH & EC).Soil analysis is a valuable tool for farm as it determines the inputs required for efficient and economic production. A proper soil test will help ensure the application of enough fertilizer to meet the requirements of the crop while taking advantage of the nutrients already present in the soil. It is very important that your sampling technique is correct as the results are only as good as the sample you take. Proper soil sampling will provide accurate soil test results and reliable nutrient recommendations.

Objectives of Soil Testing:

  • Measuring the level of Macro & Micro plant nutrients in the soil & to determine the relative ability of soil to supply crop nutrients in a particular growing season.
  • Measuring salinity, acidity & alkalinity of the soil.
  • For proper management & application of plant nutrients through manures & fertilizers.
  • Optimization & application of lime & gypsum for soil reclamation.
  • To lay-out the specific zones on fertility status for particular crop cultivation.
  • Recommendation of crop verities susceptible to salinity, acidity & alkalinity of the soil by applying proper crop rotation.

When Soil Sampling?

One month before seed sowing or transplanting is the right time of taking soil sample. Problem soil areas may be sampled anytime.

How Soil Sampling?

Soil sampling has become an important tool for assessing soil fertility. The main problem in the effective use of soil testing is obtaining proper representative soil sample. Proper soil sampling will provide accurate soil test results and reliable nutrient recommendations for a particular crop.

Collecting Sample: Sample must truly represent the field it belongs to. A field of one acre area generally treated as a single sampling unit. Larger area may be divided in to smaller homogeneous units for best representation of the soil. Areas near trees, wells, compost pit, recently fertilized plots, bunds, irrigation channels etc. must be carefully avoided during sampling. An area of about 2-3 meters along all the sides of the field should be left. Sample should be drawn from 0-15 cm i.e. plough layer of furrow slice in case of cereals, vegetables and other seasonal crops & take the sample from 8-10 cleaned marked spots of entire field. Samples should be collected from different depths in case of deep rooted & longer duration crops like sugarcane or under dry- farming conditions. In case of garden of fruit or other trees, composite sample from 0-30, 30-60 and 60-90 cm depth should be made from 4-5 pits dug in one acre field. Collect a small portion of soil up to the desires depth side by means of suitable sampling tools (Khurpi, Kassi or Phawda, Screw/Tube/Post hole Auger) from well marked 8-10 spots, moving in to zigzag manner from each individual sampling site in the entire field. Fields having standing crops in row, draw the soil sample in between the rows.

Preparing Soil Sample: Collected soil from all the spots with in one field may be mixed uniformly & thoroughly by hands on clean floor or plain sheet under the shed. Reduce the bulk sample soil to about 250-500 gm. by quartering process. Spread the entire clean bulk sample soil, divide it in to four quarters, discard two opposite ones & remix the remaining two, repeat this process until soil is left about 250 gm. & dry it properly in the shade. It may be the representative soil sample of the particular field. Transfer the sample minimum 150 gm in to clean small polythene bag. Fill all required information in Soil Sample Identification Slip and Place it in another polythene bag to avoid spreading of ink/ missing information and again put it in soil sample bag before sending to KRIBHCO Krishi pramarsh Kendra ,NOIDA for testing.
