What is Soil Testing:
In Soil Testing Procedure we make the chemical analysis of soils. The chemical analysis helps us for the quick classification of the fertility position of soils.We can also use this test for the classification of other properties like structure, texture, action capacity exchange or PH.
By using this process, we can separate out the non-deficient areas and nutrient deficient areas. The maximum and best crop production can be done by the soil. By testing the soil, we can check that which place is better for fertilization of which crop.
We can fertilize the appropriate crop on the best place by using the values which are founded by using the accurate soil analysis. It is a best tool for rational fertilizer.
Procedure of Soil Testing:
We use a variety of instruments to analyze soil samples which are:- Alpkem rapid flow analyzers
- Atomic absorption spectrophotometers
- Colorimeters
- General laboratory equipment
- Inductively coupled plasma spectrometers (icps)
- Lachat flow injection analyzer
Need of Soil Testing:
- To create a soil fertility map we need the calculation of all the important particles of soil.
- Soil Testing is also important to regulate the fertility status of soil, and by using the organic manure and chemical fertilizers we can provide the suitable nutrient.
- By using chemical fertilizers and organic manure we can provide the suitable nutrient which are required for the appropriate place.
- By this process we can take the Measurement of salinity, acidity, and sodicity of soil.
- The effective remedial measurement is also can be determined by using this process.
Most common types of Soil:
- Alluvial Soils
- Black Soils
- Desert Soils
- Laterite Soils
- Mountain Soils
- Red Soils
Tools required for sampling and Testing:
You need the following Equipment for the Soil Testing Procedure:- Atomic absorption spectrophotometer (AAS)
- Buckets
- Balances
- Centrifuge
- Flame photometer
- Labels if more than one sample is collected
- New plastic bag or sample container (located in soil kit)
- Ovens
- pH meter, conductivity meter
- Record sheet to record sample site and sample.
- Soil corer or spade
- Spectrophotometer
- Water still
