Question

please tell me something about all types of soil

Answer 1

Here's ur answer..

There are 4 main types of soil:-

1. sandy soil = it consist of whethered rocks.
2. clay soil = the particles are tightly packed together without any airspace.
3. loamy soil = combination of sand, silt and clay soils.
4. silt soil = smooth and quite fine quality of the soil that holds water better than sand.

hope it helps..
pls mark brainliest..

Answer 2

Chalky Soil

Sometimes called basic soils, they are always very alkaline. Chalk is a solid, soft rock which breaks down easily. It is very free draining, and chalky soils hold little water and dry out easily. Chalky soils are fertile, but many of the nutrients are not available to plants because of the high alkalinity of the soil, which prevents the absorption of iron by plant roots.

Clay Soil

The clay forms a heavy mass which makes it difficult for air, water and plant roots to move through the soil when wet. Once dry they form rock-hard clots. Blue or grey clays have poor aeration and must be loosened in order to support healthy growth. Red colour in clay soil indicates good aeration and a "loose" soil that drains well. Plants can take advantage of the high level of nutrients if drainage is adequate.

Loam Soil

Considered to be the perfect soil, a mix of 40 % sand, 40% silt and 20% clay. Due to mix variations loam can range from easily workable fertile soils full of organic matter, to densely packed sod. Characteristically they drain well, yet retain moisture and are nutrient rich, making them ideal for cultivation.

Peat Soil

Provided they are not too acid and have effective sub drainage, these are rich in plant foods. Converting existing soil into a peat type soil is achieved by adding large amounts of organic matter. You must avoid making your soil too acid though, and careful choice of organic matter is needed.

Sandy Soils

Sandy soils generally have a fine grained texture. They retain very little in the way of water, fertilizers or nutrients which means they are extremely poor. Prone to over-draining and summer dehydration, and in wet weather can have problems retaining moisture and nutrients and can only be revitalized by the addition of organic matter. Sandy soils are light and easy to dig, hoe and weed.

Silty Soil

Silty soil is considered to be among the most fertile of soils. Silt is often found in river estauries, because the fine particles are washed downstream and deposited when the water flows more slowly. It is also soft and smooth, with individual pieces close together. It too holds a lot of water, but the slightly larger particles make it a little better at draining than clay.
