Nutrition in Plants_LS_LA_3

Explain How Nutrients Are Replenished in the Soil. How is the growing of Leguminous crop in the field beneficial to the farmer? The first statement of this video is:

• How nutrients are replenished in soil. In this module let us learn how nutrients are replenished in soil.

• As we already know, plants absorb mineral nutrients from the soil.

• Hence their amounts in the soil keep on declining.

• Fertilizers and Manures contain plant nutrients such as nitrogen, potassium, phosphorus, etc.

• Hence, fertilizers and manures need to be added from time to time to enrich the soil.

Explain How Nutrients Are Replenished in the Soil. How is the growing of Leguminous crop in the field beneficial to the farmer? The second statement of this video is:

• Usually, crops require a lot of nitrogen to make proteins.

• As we already know, plants absorb mineral nutrients from the soil.

• Hence their amounts in the soil keep on declining.

• Fertilizers and Manures contain plant nutrients such as nitrogen, potassium, phosphorus, etc.

• Hence, fertilizers and manures need to be added from time to time to enrich the soil.

Explain How Nutrients Are Replenished in the Soil. How is the growing of Leguminous crop in the field beneficial to the farmer? The third statement of this video is:

• Usually, crops require a lot of nitrogen to make proteins.

• After the harvest, the soil becomes deficient in nitrogen.

• Hence their amounts in the soil keep on declining.

• Fertilizers and Manures contain plant nutrients such as nitrogen, potassium, phosphorus, etc.

• Hence, fertilizers and manures need to be added from time to time to enrich the soil.

Explain How Nutrients Are Replenished in the Soil. How is the growing of Leguminous crop in the field beneficial to the farmer? The fourth statement of this video is:

• Usually, crops require a lot of nitrogen to make proteins.

• After the harvest, the soil becomes deficient in nitrogen.

• The nitrogen gas is available abundantly in the air.

• Fertilizers and Manures contain plant nutrients such as nitrogen, potassium, phosphorus, etc.

• Hence, fertilizers and manures need to be added from time to time to enrich the soil.

Explain How Nutrients Are Replenished in the Soil. How is the growing of Leguminous crop in the field beneficial to the farmer? The fifth statement of this video is:

• Usually, crops require a lot of nitrogen to make proteins.

• After the harvest, the soil becomes deficient in nitrogen.

• The nitrogen gas is available abundantly in the air.

• Plants cannot use it.

• Hence, fertilizers and manures need to be added from time to time to enrich the soil.

Explain How Nutrients Are Replenished in the Soil. How is the growing of Leguminous crop in the field beneficial to the farmer? The sixth statement of this video is:

• Usually, crops require a lot of nitrogen to make proteins.

• After the harvest, the soil becomes deficient in nitrogen.

• The nitrogen gas is available abundantly in the air.

• Plants cannot use it.

• They need nitrogen in a soluble form.

Explain How Nutrients Are Replenished in the Soil. How is the growing of Leguminous crop in the field beneficial to the farmer? The seveth statement of this video is:

• The bacterium called But Rhizobium can take atmospheric nitrogen and convert it into a soluble form.

• After the harvest, the soil becomes deficient in nitrogen.

• The nitrogen gas is available abundantly in the air.

• Plants cannot use it.

• They need nitrogen in a soluble form.

Explain How Nutrients Are Replenished in the Soil. How is the growing of Leguminous crop in the field beneficial to the farmer? The eighth statement of this video is:

• The bacterium called Rhizobium can take atmospheric nitrogen and convert it into a soluble form.

• But Rhizobium cannot make its own food.

• The nitrogen gas is available abundantly in the air.

• Plants cannot use it.

• They need nitrogen in a soluble form.

Explain How Nutrients Are Replenished in the Soil. How is the growing of Leguminous crop in the field beneficial to the farmer? The ninth statement of this video is:

• The bacterium called Rhizobium can take atmospheric nitrogen and convert it into a soluble form.

• But Rhizobium cannot make its own food.

• So it lives in the roots of leguminous plants like Peas, Moong, etc, and provides them with nitrogen.

• Plants cannot use it.

• They need nitrogen in a soluble form.

Explain How Nutrients Are Replenished in the Soil. How is the growing of Leguminous crop in the field beneficial to the farmer? The tenth statement of this video is:

• The bacterium called Rhizobium can take atmospheric nitrogen and convert it into a soluble form.

• But Rhizobium cannot make its own food.

• So it lives in the roots of leguminous plants like Peas, Moong, etc, and provides them with nitrogen.

• In return, the plants provide food and shelter to the bacteria. This is called a symbiotic relationship.

• They need nitrogen in a soluble form.
