Why are manures and fertilizers added to the soil in a farm Brainly?

manual and fertilizers are added to the soil in farms to increase the fertility of soil and the production of crops.

Why is it necessary to add manure and fertilizers?

It is important to add manure and fertiliseres to the soil because in some places the soil as less nutrients for crops because the farmers grow crops after a crop in the same field. The process of adding manure and fertilisers is called manuring. If the manuring is not done on time the results seen on weak plants.

What are manures and why are they added to the soil?

Manures contribute to the fertility of soil by adding organic matter and nutrients, such as nitrogen, that are utilised by bacteria, fungi and other organisms in the soil. Higher organisms then feed on the fungi and bacteria in a chain of life that comprises the soil food web.

Why manure is added to the soil?

Manure is added to soil when soil is too acidic. Nitrogen, phosphorus and other nutrient elements are supplied by manure to increase the fertility of the soil and also speeds up decomposition, and lowers the soil’s acidity level, or pH, less than chemical fertilizers.

What do manures and fertilizers supply to the soil?

Why do we add manure to the soil?

Adding manure to soils is an excellent way to increase soil organic matter. In addition to slowly releasing plant nutrients over time, organic matter improves soil structure and the soil’s ability to hold water.

What are manures and fertilizers?

Manure is an organic substance that is obtained from decomposition of vegetables and animal waste. Fertilizers are inorganic substances manufactured in factories. Manures are relatively less rich in plant nutrients, they only remove general deficiency of soil.

Why do farmers add manure and fertilizers to the soil class 7?

Answer: As plants absorb mineral nutrients from the soil, their amounts in the soil keep on declining. Fertilizers and manures contain plant nutrients such as nitrogen, potassium, phosphorus, etc which need to be added from time to time to enrich the soil.

Why is manure added to the soil?

Why manures are advantageous for the soil?

Manure organic matter contributes to improved soil structure, resulting in improved water infiltration and greater water-holding capacity leading to decreased crop water stress, soil erosion, and increased nutrient retention.

Why are manures used?

Manure is organic matter used as fertilizer in agriculture. Manures improve the fertility of the soil by adding organic matter and lots of nutrients, such as nitrogen that is trapped by bacteria in the soil. Higher organisms then feed on the fungi and bacteria in a chain of life.
