Soil is a rich source of macro and micronutrients. The crop nutrient availability depends on various factors. Such as

1. Total nutrient content in the soil.
2. Soil texture.
3. Organic matter content.
4. Soil pH.
5. Soil aeration.
6. Nutrient interaction.

Nitrogen, Phosphorus and Potassium are considered major nutrients for plant growth. They form an integral part of the plant system. Sometimes, the soil may not be capable of providing these essential nutrients to crops, which in turn affects crop growth at later stages. 

Nutrient deficiencies lead to poor crop growth in turn affecting the total yield. Some of the deficiencies include:

1. Lack of Nitrogen results in Chlorosis of leaves- loss of chlorophyll content. Leaves turn yellow.
2. Phosphorus deficiency leads to stunted growth, and leaves turn reddish-purple colour and fall off.
3. Potassium deficiency in plants results in yellowing at the tip and edges. Dead or yellow patches or spots on leaves.

The lack of each nutrient has several effects on the individual crop. It should be rectified and corrected immediately with the right amount of fertilizers to overcome future crop loss. Your soil must be tested to know which fertilizer and how much quantity of fertilizer is to be added to the soil. 

Physical soil testing has many limitations:

1. Time-consuming 
2. Requires physical soil sampling
3. Reports are not available instantly
4. Not a very cost-effective solution

It is possible to test soils without physically sampling them using http://sat2farm.com/ technology.
