What is the Process of Soil Testing?

Agricultural Soil Testing – Why its done

Soil testing is extremely vital for agriculture. A good soil pH and conductivity will help a plant to provide better crop yields because the soil fertility and structure is ideal for the plants growing conditions. Experts suggest that competent use of key information obtained from soil testing can help ensure better management of soil. Farmers can use soil testing to evaluate the fertility level of their agricultural land. Based on the results obtained, they can use organic or inorganic fertilizers to improve their soil.

Soil Testing Equipment

Additionally, contractors and civil engineers can use soil testing results to assess the suitability of land for construction purposes. What kind of foundation should be used and what construction material is needed – all this information can be easily determined using the soil test.

What is a Soil Test?

Soil testing refers to any physical or chemical measurement performed on the soil. The main objective of soil testing is to assess the physical and chemical characteristics and composition of the soil.

The soil test results carry valuable information but the accurate and precise results can be obtained only when performed using professional soil testing equipment.

Why is Soil Testing Important?

• To evaluate soil fertility and productivity by analyzing its nutritional level.
• To determine specific issues in the soil.
• To determine the suitability of soil for different applications.
• To anticipate the response of crops to fertilizers.
• To recommend the right use of fertilizer.

How Is A Soil Test Performed?

Performing soil tests requires the use of specialized Soil Testing Lab Equipment and accessories. The process to perform soil testing is divided into the following phases:

• Collection of the sample.
• Extraction of nutrients.
• Determination of physio-chemical properties of soil.
• Analysis of analytical results.
• Recommendations and follow-up of results.

How to Perform Representative Soil Sampling?

As soil is a heterogeneous mass the highest probability of discrepancy arises from soil sampling itself. The sample should be uniform and representative of the area from where it is collected. Also, all disparities in color, slope, textures should be precisely considered.

For fast and efficient sampling use soil drilling and extraction equipment, including:

• Augers.
• Handles and extensions.
• Quick connect auger adapter.
• Quick connect pins.
• Test Sieves.
• And one-piece soil samplers.

For sampling first divide the area to be sampled into different zones depending on color, texture, and slope. And once you have classified the site, make a V shape cut into soil extending to (0-15) cms of depth. From this extract 2-3 cm thick vertical slices. Similarly, collect 10-15 samples. Next mix samples using a sample quartering kit. The sample should be carefully stored in a Polythene/paper/cloth bag for further laboratory analysis.

Precautions To Be Taken While Soil Sampling

• Remove debris, gravel, and stones from the surface before collecting a sample.
• Wet the soil first and then collect samples.
• If soil is moist and has lumps make sure to break them into smaller pieces.
• Take different samples from areas of different appearances.
• Store samples in a clean bag.
• Air dry the soil sample and sieve it through a 2 mm sieve.
