Question

What nutrients is loamy soil composed of and where can it be found in India ?

Answer 1

Answer:

Loam is soil composed mostly of sand (particle size > 63 micrometres (0.0025 in)), silt (particle size > 2 micrometres (7.9×10−5 in)), and a smaller amount of clay (particle size < 2 micrometres (7.9×10−5 in)). By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively.[1] 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.[1] In the United States Department of Agriculture 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.[2] Loam soil is suitable for growing most plant varieties.

Bricks made of loam, mud, sand, and water, with an added binding material such as rice husks or straw, have been used in construction since ancient times.

Answer 2

Answer:

In my opinion this is your answer:-

Loam is soil composed mostly of sand, silt, and a smaller amount of clay .

By weight, its mineral composition is about 40% concentration of sand, 40% concentration of silt and 20% clay.

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.

It is rich in potash content but lacks phosphate, humus and nitrogen content.

Loamy soil is found in regions such as Tamil Nadu, Madhya Pradesh, Jharkhand, Odisha, some parts of Karnataka and southeast Maharashtra.

Explanation:

Three layers of subsurface loam; surface layer is dark brown fine sandy loam, subsurface layer is pale brown fine sandy loam, subsoil is red clay loam and sandy clay loam.

I hope it helps.

Thank you.
