In Soil testing kit following parameters can be tested:-

1. Ph - Most greenhouse crops can grow satisfactorily over a fairly wide pH range. The action to take on pH depends on the specific requirements of the plants being grown in that particular soil.

2. Electrical Conductivity - Soluble salts are the total dissolved salts in the root substrate (medium) and is measured by electrical conductivity (EC). Measuring EC or soluble salts provides a general indication of nutrient deficiency or excess.  A high EC reading generally results from too much fertilizer in relation to the plant’s needs, but inadequate watering and leaching or poor drainage are other causes.  Sometimes high EC levels occur when root function is impaired by disease or physical damage.  

3. Organic Carbon-It is the basis of soil fertility. It releases nutrients for plant growth, promotes the structure, biological and physical health of soil, and is a buffer against harmful substances.

4. Nitrogen / Phosphorous and potassium are Major nutrients.

• Nitrogen is an important building block of proteins, nucleic acids and other cellular constituents which are essential for all forms of life. Nitrogen is such an important key nutrient element for plants that it requires careful management, and – if mismanaged – can lead to severe environmental problems.

Testing for these major nutrients is majorly done to facilitate the farmer with the knowledge towards the required fertilizer composition and dosage selection for the land under agriculture or horticulture.

• Phosphorus is a component of the complex nucleic acid structure of plants, which regulates protein synthesis. Phosphorus is, therefore, important in cell division and development of new tissue.
• Potassium is an essential plant nutrient that plays a role in a wide range of physiological processes, from regulation of the stomata to enzyme activation.

The tests on all the above parameters can be performed easily as can be seen in the demonstration performed by the lab technician. Based on the efficiency of the person performing test around 50 individual soil samples can be tested using this kit.

These kits have been packed such that you can have a lab at field – thus making testing at source a reality. Soil chemistry changes over time, as biological and which chemical processes break down or combine compounds over time. These processes change once the soil is removed from its natural ecosystem (flora and fauna that penetrate the sampled area) and environment (temperature, moisture, and solar light/radiation cycles). As a result, the chemical composition analysis accuracy can be improved if the soil is analyzed soon after its extraction — usually within a relative time period of 24 hours. With this background the “Testing at Source “concept provides more accurate results.
