3. Black soil is also called as……..soil
4. The excessive spraying of chemical and use of chemical fertilisers lead to …….​

Answer 1

Answer:

Weathering

Soil organic matter contains glomalin, dopplerite and humic acid.

Regur

soil degradation

Step-by-step explanation:

1. :- The process of disintegration of rocks and formation of soil due to the various elements of weather such as wind, rain etc.

2. In soil science, organic matter is referred to as organic matter. Soil organic matter contains glomalin, dopplerite and humic acid.

• Organic matter or bio-derived material is any material derived from living things.
• Most of these substances contain carbon and are capable of decay.
• Examples of biological materials are wood, straw, humus, manure, bark, crude oil, cotton, spider silk, chitin, fibrin and bone.
• Soil is made up of both bio-living and once-living things, such as plants and insects and inorganic matter inanimate elements, such as minerals, water, and air.
• Soil contains air, water and minerals as well as plants and animals, both living and dead.
• These soil components fall into two types.

3. Black soil is also known as regular soil. The soil comprises various amounts of vital nutrients necessary for cultivation. The soil is the top part of the earth’s surface, including disintegrated rock, humus, inorganic, and organic materials. Soil is classified based on size, colour and texture. Black soil is a type of soil that comes under the category of soil classification based on colour.

4. The excessive spraying of chemical and use of chemical fertilisers lead to soil degradation

Answer 2

1. The weathering of rocks turns them into a powdery material.

2. The biotic material produced that gets mixed with the soil is called Organic Material.

3. Black soil is also called Regur soil.

4. The excessive spraying of chemicals and use of chemical fertilizers leads to soil degradation.

Weathering of the rock due to environmental conditions like rain.

The huge source of carbon-based chemicals found in natural and manmade, terrestrial and aquatic habitats is referred to as organic matter, organic material, or natural organic matter. It is organic matter made up of organic compounds derived from the excrement and remains of living organisms such as plants and animals.

Black soil: This is also known as regur soil. It is usually seen in Gujarat, Maharashtra, Karnataka, and Madhya Pradesh.

Soil degradation is described as a deterioration in soil health that causes the ecosystem's ability to offer goods and services to its beneficiaries to be harmed.
