How can nitrogen be replenished in soil naturally?

Plant and animal wastes decompose, adding nitrogen to the soil. Bacteria in the soil convert those forms of nitrogen into forms plants can use. Plants use the nitrogen in the soil to grow. People and animals eat the plants; then animal and plant residues return nitrogen to the soil again, completing the cycle.

How can nitrogen be replenished in soil naturally Class 8?

How can nitrogen be replenished in soil naturally? Answer: Through crop rotation with a leguminous crop the nitrogen can be replenished in soil naturally. The leguminous plants, like peas, beans, soybeans, peanuts, etc., have nitrogen-fixing bacteria in their root nodules.

How are nutrients replenished in soil naturally?

Nutrients can be replenished in the following ways: Fertilisers and manures contain plant nutrients such as nitrogen, phosphorous and potassium, etc. So, when fertilisers and manures are added to the soil in the fields, then the soil gets enriched with nutrients like nitrogen, phosphorous and potassium, etc.

How are nutrients replenished in the soil naturally and artificially?

Why do we need to replenish the nutrients in soil Class 8?

It is necessary to replenish the nutrients into the soil because all the nutrients that soil has are used up by the plants during their growth so for the continuos supply of nutrients to the plants it is necessary to replenish the soil again and again.

How do leguminous plants replenish nitrogen?

Leguminous crops, such as peas, pulses and gram, have Rhizobium bacteria in their root nodules. The Rhizobium bacteria have the ability to convert the atmospheric nitrogen into a form that can be used by the plants. Thus, these bacteria help in replenishing nutrients in the soil by providing nitrogen to the plants.

How is humus helpful in replenishment of soil?

Answer: When we leave the field undisturbed without growing any crop on it, a lot of humus grow in it along with soil bacteria. This way soil becomes rich in nutrients. Thus, vitality of the soil is regained for the next crop.
