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 leguminous plants after a cereal 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 farmers prefer to grow leguminous crops alternatively with cereal crops in their field?
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.
Why farmer grow beans in between two regular crops?
Plants between rows and in alley intercropping, in particular, mitigate erosion with their roots. Added nutrients for the main crop. The leguminous family is known for nitrogen fixation and thus provides nitrogen for the neighboring species.
Why do farmers prefer to grow a crop of legume family such as peas or gram after cultivating wheat for a season?
Answer. Answer: Farmers grows leguminous crops after harvesting of cereals: The farmers plant leguminous crops after harvesting cereals to replenish the nitrogen content of the soil. The leguminous plants contain the symbiotic nitrogen fixing bacteria that live in their root nodules.
What is crop rotation Class 8?
Crop rotation:
Crop rotation is a technique of systematic plating of crops in a specific order over several years in the same agricultural field. There is a specific level of nutrients in the soil, which is used by the plants. Every specific plant has a specific requirement of nutrients from the soil.
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.
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 farmers do not add fertilizers during cultivation of leguminous crops Class 7?
Answer: Farmers do not add fertilisers during cultivation of leguminous crop because roots of leguminous plants have symbiotic association with a bacterium called Rhizobium which fixes atmospheric nitrogen into the soil.
Why do some farmers plant legumes such as peas to improve the nitrogen levels in the soil?
Why might farmers plant legumes such as peas to improve the nitrogen levels in their soil? Legumes contain a high level of nitrogen, which are leeched into the soil. This allows the farmer to then plant crops such as corn that uses nitrogen.
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.
What are the advantages of growing beans?
Common beans provide farmers with high returns on investments, require less labor and external inputs than many other crops. Soil fertility improvement through biological nitrogen fixation: Where farmers have limited resources and poor access to input markets, organic sources of nitrogen are vital.
Why do farmers grow different crops in a field?
Farmers grow different crops in a field because different crops may vary in nutrient requirements. This ensures complete and uniform utilization of nutrients present in soil. In this way, it prevents the soil from being deficient of a particular nutrient.
How can a farmer grow a good and healthy crop Class 5?
After deciding what to grow, farmers often till the land by loosening the soil and mixing in fertilizers, which are nutrient rich. Then, they sow seeds or plant seedlings. When the crops are growing, farmers must water (or rely on rainfall), weed and kill crop pests.
Why do we need to grow crops Class 8?
Crops are the main need to feed our hunger. It is the source of income for farmers. Raw materials like starch, cellulose, and oil are extracted from the plants. Crops are the means of nutrition and are the source of survival.
How legumes and pulses are important in increasing soil and crop productivity?
Legumes improve soil fertility through the symbiotic association with microorganisms, such as rhizobia, which fix the atmospheric nitrogen and make nitrogen available to the host and other crops by a process known as biological nitrogen fixation (BNF).
What is humus 7th?
Answer: Humus is a dark-coloured organic matter formed by the decomposition of plant and animal remains present in the soil. It holds the topsoil in place. It absorbs and holds the water useful for growing plants. It provides food for various plants and animals present in the soil.
How does field fallow improve soil fertility?
Other benefits of fallowing soil are that it raises levels of carbon, nitrogen and organic matter, improves moisture holding capacity, and increases beneficial microorganisms in the soil. Studies have shown that a field that has been allowed to lie fallow for just a year produces a higher crop yield when it is planted.
What are weeds Class 9?
Weeds are the unwanted plants that grow in the garden or fields of crops and prevent the growth of desirable plants. They are the plants which are not grown by the farmers. Examples include grass, dandelions, plantain, thistle, etc. Was this answer helpful?
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.
What happens to the soil after growing cereal crops repeatedly in the same field?
If only one crop is grown repeatedly in the soil, it loses its fertility and gets devoid of nutrients. For this reason crop rotation is an important procedure, so that the fertility of the soil is retained and there is no loss of nutrients.
