Red soil is one of the best types of soil we can find in our country. Especially in states such as Tamil Nadu, southern Karnataka, north-eastern Andhra Pradesh and some parts of Madhya Pradesh, Chhattisgarh, and Odisha. Red soil is formed by combining rock material and mountains. Hence red soil is mainly found in the mountain regions. The red colour is due to the high iron content. As they are found in less rainfall region, the soil turns red in colour due to sun. best soil suppliers chennai
The reason why red soil is preferred for gardening and horticulture is the drainage. Some of the major crops of India including groundnut, millet, ragi, rice, potato, sugarcane, wheat and tobacco are grown in red soil.

When you pour water onto your soil and drains quickly. It is most likely to be sandy or gravelly soil as with clay soil the water will take longer to sink in. [ Best Soil and Sand Suppliers Chennai VAT ]
Grab some soil and press it. If it is sticky and retains the shape when you let go, it is clay soil. If the soil is spongy, it is peaty soil. Sandy soil will fall apart easily. Loamy soil will have a very smooth texture but will retain the shape for a small period of time.
Add soil to a transparent container, add water, shake well and then leave to settle for 12 hours.
Clay & silty soils will leave cloudy water with a layer of particles at the bottom. Sandy soils will leave the water clear. Most of the particles will fall, forming a layer on the base of the container. Peaty soils will see many particles floating on the surface; the water will be slightly cloudy with a thin layer at the bottom. Soils that are chalky will leave a layer of white fragments on the bottom of the container. If the water is quite clear with layered particles on the bottom of the container with the finest particle at the top – this soil is likely to be a loamy one.
The pH for soils usually ranges between 4.0 and 8.5. Plants favour soil which has a pH between 6.5 and 7 because this is the level where nutrients and minerals naturally thrive. As a general rule, in areas with soft water you will have acid soil and hard water areas will tend to have alkaline soil.
Use a soil test kit to assess primary nutrients (N-P-K) as well as pH levels. By testing your soil, you determine its exact condition so you can fertilize more effectively and economically. Soil should be tested periodically throughout the growing season.
