Question

What are the benefits of applying manure to the crops?


Full Explain it!!!​

Answer 1

Explanation:

Manure is the decomposed form of dead plants and animals, which is applied to the soil to increase production. It is a natural form of fertilizer and is cost-effective. The human and animal excreta is also used as manure. The livestock manure is rich in nitrogen, phosphorus, and potassium.It is highly rich in organic matter and humus and thus improves the soil fertility. These are better in the long run and does not cause any pollution. It is a valuable and renewable resource.

Cattle dung, urine, and slurry from biogas plants.

Wastes from human habitation such as human urine, night soil, sludge, sewage, domestic waste.

Droppings of goat and sheep

Waste from the slaughterhouses such as bones, meat, horn and hoof meal, fish waste

By-products of agricultural industries

Crop waste

Weeds, water hyacinth

Types of Manure

Manure can be grouped as farmyard manure, green manure and compost manure. Following are the different types of manure used by the farmers:

Green Manure

Green manure increases the percentage of organic matter in the soil. The roots of such manures go deep into the soil. These help in the suppression of weeds and the prevention of soil erosion.

Farmyard Manure

Farmyard manure improves the soil structure and is used as a natural fertilizer in farming. It increases the soil capacity to hold more water and nutrients. It also increases the microbial activity of the soil to improve its mineral supply and also the plant nutrients.

Compost Manure

It improves the soil structure and water and nutrient holding capacity of the soil. Thus, it increases the nutrient value and thereby improves the health of the plants.

Advantages of Manure

These are a good source of macronutrients.

• Improves soil fertility.
• Cost-effective
• Reduces soil erosion and leaching.
• Improves the physical properties of the soil and aerates the soil.
• Improves the water and nutrient holding capacity of the soil.
• It can be transported easily.

Methane gas is evolved as the by-product of manure that can be used for cooking and heating purposes.

The crops grown on the land treated with manure produces healthy crops.

Manure is an ideal soil amendment. When it is applied to the agricultural fields it acts as a field residue. Farmers can sell the manure to people who need to improve their soil fertility. Thus, it can bring income to farmers. They add to the overall soil ability and sustainability. Manure increases the water holding capacity of the soil. The organic content of the soil can also be improved by applying raw manure like biochar, compost, etc.

Advantages of Manures

1)It enhances the water holding capacity of the soil.

2)It makes the soil porous due to which the exchange of gases become easy.

3)It increases the number of useful microbes in the soil.

4)It improves the texture of the soil.Improves soil fertility.

Reduces soil erosion and leaching.

Improves the physical properties of the soil and aerates the soil. Improves the water and nutrient holding capacity of the soil.

Manure has been applied widely in the production of many produce crops to provide organic matters and nutrients, especially among organic producers.
