what is meant by sandy soil clay soil and loamy soil give any two properties of each of sandy soil clay soil and loamy soil
Answers
Sandy soils have a light texture and loose structure, which cause them to drain quickly and not hold water well. This can lead to low fertility, but with the addition of some compost, manure or leaf mold, sandy soil can grow a satisfactory garden. This type of soil is dries quickly and is easy to work.
Loam is soil composed mostly of sand in)), silt and a smaller amount of clay By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively.These proportions can vary to a degree, however, and result in different types of loam soils: sandy loam, silty loam, clay loam, sandy clay loam, silty clay loam, and loam. In the USDA textural classification triangle, the only soil that is not predominantly sand, silt, or clay is called "loam". Loam soils generally contain more nutrients, moisture, and humus than sandy soils, have better drainage and infiltration of water and air than silt and clay-rich soils, and are easier to till than clay soils. The different types of loam soils each have slightly different characteristics, with some draining liquids more efficiently than others. The soil's texture, especially its ability to retain nutrients and water are crucial. Loam soil is suitable for growing most plant varieties.

Properties of Soil
The upper layer of earth in which plants grow is called soil. It is black or dark brown material typically consisting of a mixture of organic remains, clay, and rock particles. The soil has the following special properties:
1. Texture
The texture of the soil depends upon the relative amount of these particles. Clay has the smallest sized particles. Because of very small size, the clay is felt smooth. Silt particles are larger than the clay particles. There size range from0.002 to 0.02mm in diameter. So silt does not feel smooth. Sand particles are largest sized particles of soil. Their diameter is more than0.02mm
2. Absorption of water
Water holding capacity in different types of soils is different. Soil absorbs water because it is porous. Sandy soil holds less water than clay soil and loamy soil. Clay soil holds more water than sandy soil. Sand absorbs less water than clay. Some plants require more water to grow; they grow well in clay soil and loam soil, since sand hold less water, so less vegetation is found in sandy soil.
3. Moisture
Texture decides the water holding capacity of the soil. The soil has some amount of water inside it as a moisture. Water is usually present as a thin film around the soil particles. It is absorbed by the roots of the plants. The capacity of a soil to hold water is important for the growth of various crops. Even a dry soil has some water in it.
