How to collect soil sample
Collect the soil sample during fallow period.
In the standing crop, collect samples between rows.
Sampling at several locations in a zig-zagpattern ensures homogeneity.
Fields, which are similar in appearance, production and past-management practices, can be grouped into a single sampling unit.
Collect separate samples from fields that differ in colour, slope, drainage, past management practices like liming, gypsum application, fertilization, cropping system etc.
Avoid sampling in dead furrows, wet spots, areas near main bund, trees, manure heaps and irrigation channels.
For shallow rooted crops, collect samples up to 15 cm depth. For deep rooted crops, collect samples up to 30 cm depth. For tree crops, collect profile samples.
Always collect the soil sample in presence of the farm owner who knows the farm better
Procedure
Divide the field into different homogenous units based on the visual observation and farmer’s experience.
Remove the surface litter at the sampling spot.
Drive the auger to a plough depth of 15 cm and draw the soil sample.
Collect at least 10 to 15 samples from each sampling unit and place in a bucket or tray.
If auger is not available, make a ‘V’ shaped cut to a depth of 15 cm in the sampling spot using spade.
Remove thick slices of soil from top to bottom of exposed face of the ‘V’ shaped cut and place in a clean container.
Mix the samples thoroughly and remove foreign materials like roots, stones, pebbles and gravels.
Reduce the bulk to about half to one kilogram by quartering or compartmentalization.
Quartering is done by dividing the thoroughly mixed sample into four equal parts. The two opposite quarters are discarded and the remaining two quarters are remixed and the process repeated until the desired sample size is obtained.
Compartmentalization is done by uniformly spreading the soil over a clean hard surface and dividing into smaller compartments by drawing lines along and across the length and breadth. From each compartment a pinch of soil is collected. This process is repeated till the desired quantity of sample is obtained.
Collect the sample in a clean cloth or polythene bag.
Label the bag with information like name of the farmer, location of the farm, survey number, previous crop grown, present crop, crop to be grown in the next season, date of collection, name of the sampler etc.
After your soil is tested, you will get the results in the form of soil health card and will be sent through mail as well. These results will tell you if your soil needs more nutrients. Then you can decide to add more compost or to use fertilizer
Be careful with fertilizer

ஒரு ஏக்கருக்கு 4 முதல் 5 இடங்களில் மண் எடுத்துக் கொள்ள வேண்டும் மற்றும் ஏக்கருக்கு 20 இடங்களில் மண் எடுத்துக் கொள்ள வேண்டும்
ஐயா வணக்கம், மூன்று வயல்களில் வெவ்வேறு கலர் மண் இருக்கிறது. மூன்றையும் தனித்தனியாக (sample) எடுக்க வேண்டுமா இல்ல ஒன்றாக எடுக்க வேண்டுமா? உங்களுக்கு courier செய்தால் சோதனை செய்து சொல்வீர்களா?
