Legumes fix the atmospheric nitrogen, release in the soil high-quality organic matter and facilitate soil nutrients’ circulation and water retention. Based on these multiple functions, legume crops have high potential for conservation agriculture, being functional either as growing crop or as crop residue.
Why does a farmer grows leguminous like peas grams and beans in his field?
Leguminous plants such as peas and beans have Rhizobium. It is a bacterium which resides in their root nodules. It helps in fixing the atmospheric nitrogen and transforms it into nitrates and nitrites which are absorbed by the plants.
Why do farmers prefer to grow leguminous plants?
Farmers use leguminous crops to provide nitrogen to the soil because nitrogen-fixing bacteria found in roots of leguminous plants like as peas, pulses crop etc. These bacteria (like rhizobium) atmospheric nitrogen fixed in the soil. Was this answer helpful?
Why do farmers grow legume crops in field after growing the wheat crop?
The leguminous plants have nodes in their roots where the nitrogen-fixing microbes reside. These microbes help by fixing the nitrogen in the soil. Hence increasing the nitrogen level of soils. So the farmers plant the leguminous plants to maintain the nitrogen level of the soil.
Why do farmers often plant legumes between cropping seasons?
Changing crops routinely allows the land to remain fertile, since not all of the same nutrients are being used each season. For example, planting a legume, such as soybeans, helps to replenish necessary nitrogen in the soil.
Why do farmers prefer to grow beans and peas in nitrogen deficient soil Class 8?
Beans and pea are the examples of leguminous plants. These plants contain Rhizobium bacteria in their root nodules which help in fixing atmospheric nitrogen. This results in the enrichment of soil with nitrogen and increases its fertility. Therefore farmers prefer to grow pea and beans in nitrogen deficient soil.
Why do farmers grow leguminous plants after a cereal crop Class 7?
After the leguminous plants utilize some of the nitrogen compounds, the rest of it is left in the soil to enrich it. Thus, planting a leguminous plant will result in nitrogen rich soil and when a cereal is grown in this soil there is increase in food grain production.
Why do farmers grow legumes and cereals alternately in field Class 8?
farmers grow leguminous alternatively in thier fields. This is because a microorganism called Rhizobium lives in the roots of leguminous plants. these microorganism help in fixing nitrogen in the soil.
Why do farmers grow beans and peas after cereal crops like wheat maize or rice?
When farming cereals like maize and wheat, farmers have improved yields and soil fertility by incorporating pulses into crop rotations (rotating different crops on the same land) or intercropping (growing two or more crops among each other).
How are legume plants important to farmers?
Legumes fix the atmospheric nitrogen, release in the soil high-quality organic matter and facilitate soil nutrients’ circulation and water retention. Based on these multiple functions, legume crops have high potential for conservation agriculture, being functional either as growing crop or as crop residue.
Why do farmers Plough a crop of legumes into the ground rather than harvest it?
Leguminous plants have a symbiotic relationship with N-fixing bacteria held in nodules on their roots. They can capture nitrogen from the atmosphere and turn it into nitrates – a form plants can use. By plowing these roots into the soil, the nitrogen content in the soil would increase.
What are the benefits of planting legumes?
Soil quality benefits of legumes include: increasing soil organic matter, improving soil porosity, recycling nutrients, improving soil structure, decreasing soil pH, diversifying the microscopic life in the soil, and breaking disease build-up and weed problems of grass-type crops.
Why do farmers rotate crops so that a field that has grown mostly corn will grow soybeans another year what do they need to replenish?
Rotating corn and soybeans allows farmers to use less nitrogen fertilizer when growing corn. That benefits the environment and allows farmers to save on input costs.
What is the advantage of planting a leguminous crop between two grain crops?
A leguminous crop fixes atmospheric nitrogen with the help of nitrogen fixing bacteria. It helps in the addition of nitrogen into the soil without adding extra nitrogenous fertilizer to the soil.
How do you think growing peas will help in replenishing the soil Class 8?
Pea is a leguminous plant. The roots of leguminous plants contain the nitrogen-fixing bacteria known as. They convert atmospheric nitrogen into a usable form (nitrates) that can be utilised by plants easily. Nitrogen increases the fertility of soil, thereby replenishing the soil fertility.
Why are pea plants sown in a field after a crop of wheat is harvested Class 8?
So, farmers grow leguminous plants between main crops to enrich the soil with nitrogen and to reduce the use of chemical fertilizers. Therefore, Pea is a leguminous plant. Growing pea plant along with wheat crop helps in enrichment of soil due to nitrogen fixing property of leguminous plants.
Is pea a leguminous plant?
For example, a pea pod is a legume, but the pea inside the pod is the pulse. The entire legume plant is often used in agricultural applications (as cover crops or in livestock feed or fertilizers), while the seeds or pulses are what typically end up on our dinner plates.
What is the role of legumes in a crop rotation Programme Class 8?
Answer. legumes fix the atmospheric nitrogen into soil so that the next crop can use the nitrogen components which helps in the high yield of the crop.in this way the nutrients of the soil will not get depleted.
Why do farmers plant leguminous crops in crop rotation mixed cropping in Tamil?
They help to convert atmospheric nitrogen to nitrate salts in the soil thereby adding to soil fertility.
3. Hence growing leguminous crops in crop rotations / mixed cropping helps to maintain fertility of the soil.
How does growing legumes alternatively with wheat in the same field improve soil nutrition class 8?
The root nodules of leguminous plants have nitrogen fixing bacteria(called Rhizobium)which can directly convert atmospheric nitrogen into nitrogen compounds. These nitrogen compounds go into the soil and improves the fertility.
What are leguminous plants for Class 8?
Answer: A leguminous plant is a group of flowering plants that have vegetables or as foods grown from the ground knobs that enhance the ability of nitrogen-rich material. Examples: acacia, peas, clover, beans and gorse.
