Why is it important to add fertilizer and manure to the soil?

When crops are grown one after the other, it decreases the productivity of the soil. However, this can be overcome by adding manures and fertilizers to the soil. This increases the yield of the plants and also restores the productivity of the soil.

Why do farmers use manure and fertilizers in their fields?

Farmers use a combination of manures and fertilizers in their field to replenish the nutrients. The use of fertilizers has helped farmers to get better yield of crops because they are very rich in plant nutrients. The use of manure improves the porosity of the soil to make the exchange of gases easy.

Why does a farmer add manure or fertilizer to the soil class 7?

Farmers add fertilisers and manures to the field because fertilisers and manure conserves and enriches the fertility of the soil. When plants are grown again and again on the same soil, the soil becomes deficient in nutrients. Thus it is necessary to replenish the soil with these nutrients.

Why do farmers use fertilizer?

Fertilizer provides plants with all sorts of nutrients that they need to grow strong and healthy, including, most importantly, nitrogen, phosphorus, and potassium. That’s why farmers all over the world, in countries rich and poor, put manure on their crops.

What is manure and its advantages?

Manure is a nutrient-rich organic matter used as organic fertilizer in agriculture. The advantages of adding manure to soil or in agricultural fields:- 1) It helps to improve the soil structure. 2) It increases the nutrient content in the soil.

Why are manure and fertilizers used in fields class 9th?

Manure is made from decomposing plant’s parts and animals waste. Therefore, it is rich in nitrogen, phosphorus, potassium and other nutrients. – All these nutrients are essential for plant growth, thus using manure as fertilizers in fields provide crops with all required growth factors.

How do farmers add manure to the soil?

To make manure, decomposition of plants and animal waste is done by farmers. The product of this decomposition is a material rich in organic matter which we call manure. Manure does not have a high content of nutrients. Instead, it gives fertility to the soil by adding humus (an organic component of the soil).

When farmers add fertilizer to soil What are they normally adding to the soil?

Most fertilizers that are commonly used in agriculture contain the three basic plant nutrients: nitrogen, phosphorus, and potassium. Some fertilizers also contain certain “micronutrients,” such as zinc and other metals, that are necessary for plant growth.

When farmers add fertilizer to soil What are they normally adding to the soil what forms of nitrogen?

Most commercial fertilizers contain plant-available N in one of two inorganic forms: ammonium (NH4+) or nitrate (NO3-). Another form of N that can be synthesized by fertilizer manufacturers and is commonly used by growers is urea.

What are the advantages of adding manure to the field?

Environmental Benefits of Manure Application

• Increased soil carbon and reduced atmospheric carbon levels.
• Reduced soil erosion and runoff.
• Reduced nitrate leaching.
• Reduced energy demands for natural gas-intensive nitrogen(N) fertilizers.

What is manure and fertilizer Class 9?

Manures are natural fertilizers. They are bulky sources of organic matter which supply nutrients in small quantities but organic matter in large quantities. Manures are prepared by the decomposition of animal excreta and plant waste. Manures include farmyard manure (FYM), compost, green manure etc.

Why do we use fertilizer in field?

Fertilizers replace the nutrients that crops remove from the soil. Without the addition of fertilizers, crop yields and agricultural productivity would be significantly reduced. That’s why mineral fertilizers are used to supplement the soil’s nutrient stocks with minerals that can be quickly absorbed and used by crops.

Why do farmers add manures and fertilizers to the field?

Manures and fertilizers help in conserving and enriching the fertility of the soil. By growing plants again and again on the same soil, the soil becomes deficient in nutrients. Thus it is necessary to replenish the soil with these nutrients. That’s why farmers add manures and fertilizers to the field.

What does manure do to soil?

Manure feeds microorganisms…worms…black gold for sure. Adding manure to soil is a WIN WIN proposition. It adds nutrients and improves the soil by making it looser and helps it hold water better. And if you raise animals, you will have a lot of manure on hand.

Can you make money with manure as fertilizer?

In these areas it will be much more difficult to use fertilizer value of the manure to significantly offset transportation costs to fields with fertilizer need. There are excellent opportunities to make money with manure as fertilizer by closely linking new facilities with nearby row crop production ground.

What do you mean by the term manure?

The term manure implies to the any material with the exception of water which when added to the soil makes it productive and promotes plant growth. Some useful microbes are useful to plants like nitro bacter,azerobacter, etc.. this can only grow in the manures .
