Question

Describe two types of Manures?

Answer 1

Hint: Manure is a type of organic fertilizer used in the field of agriculture.
Manure helps in improving the fertility of the soil by adding organic matter and lots of nutrients such as nitrogen that is trapped by bacteria in the soil.

Complete answer:
Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life.
Earth's body of soil is called the pedosphere.
It has four important functions:
1. As a medium for plant growth
2. As a modifier of Earth's atmosphere
3. As a habitat for organisms
To increase the fertility of soil, farmers add some manures and fertilizers into the soil.
Manures are the organic matter used as fertilizers by the farmers in the field of agriculture.
Fertilizers are the chemicals used by the farmers to increase the crop yield and to increase the fertility of soil.
Two types of manures are discussed below:
Animal manure:
Animal manure is mainly composed of faeces.
There are two types of animal manure:
1. Farmyard manure
2. Farm slurry.
Farmyard manure contains the plants materials for as bedding animals which has absorbed faeces and urine.
In a farm slurry, it consists of bedding concrete or slats.
Green manure:
Green manure is a special kind of fertilizer where the specific plants are grown and plowed under the soil in order to enrich the soil.
It is used both domestically and industrially because it nourishes soil by releasing nitrogen, potassium, and phosphorus which are great value nutrients for crops.
We can increase Production or yield of crops by using green manure.
It can also be used to prevent soil erosion, increase water holding capacity of soil and improve the soil marginally.

So, the correct answer is Animal manure and Green manure.

Note: Some properties contribute to soil fertility in many conditions:
1. Adequate soil depth for proper root growth and water retention.
2. Topsoil or horizon is with sufficient soil organic matter for healthy soil structure and soil moisture retention;
3. Soil pH in the range 5.5 to 7.
4. Adequate concentrations of essential plant nutrients.
5. Presence of a proper range of microorganisms that support plant growth.
