Question

The plants which grown specially and are ploughed back into the soil for more production

Answer 1

Yeah.It is done.
In this way there is less chance for a plant to get less nutrition in its young stage.Because sometimes it may happen that the soil is not able to meet the needs for nutrition of so many young plants at a time.

Answer 2

Answer:

Black gram, cluster beans, cowpeas, and other plants are produced especially to make manure. They are known as "green manure" and are plowed back into the ground. synthetic fertilizers Chemical fertilizers are man-made plant nutrients created in factories.

Explanation:

A crop that is grown expressly to be absorbed into the soil while still green is known as "green manure" in agriculture. [1] As is frequently done with (brown) manure, the biomass of green manure is typically mixed with a plow or disk. The main objective is to enrich the soil with organic matter for its beneficial effects. Green manuring, especially in organic farming but also in conventional farming, is frequently employed with legume crops to supply nitrogen to the soil for the next harvests.

• By producing humic acid and acetic acid, green manure primarily serves as a soil-acidifying material to lower the alkalinity/pH of alkali soils.

• The nutrients stored in the green manure may be liberated and made available to the subsequent crops by incorporating cover crops into the soil. This happens right away as a result of an increase in the number of soil microorganisms that help decompose this new material by degrading plant matter. The re-incorporation of nutrients contained in the soil in a specific form, such as nitrogen (N), potassium (K), phosphorus (P), calcium (Ca), magnesium (Mg), and sulfur (S), is also made possible by this extra breakdown (S).
• Mycelium and viscous materials are created as a result of microbial activity from the integration of cover crops into the soil, improving the soil's structure and promoting soil health (i.e. by aggregation). [3]
• The higher proportion of organic matter (biomass) enhances soil aeration, water infiltration, and retention. Compared to non-aggregated soil, the soil may be turned or tilled more readily. The capacity of many green manure species' root systems to readily penetrate dense soils contributes to further soil aeration. With increased rates of decomposition, the quantity of humus in the soil also rises, which is advantageous for the growth of the crop that replaces the green manure crop. The main purpose of non-leguminous crops is to boost biomass.
• Some types of green manure have deep-rooted root systems that can get nutrients that shallower-rooted crops cannot.
• Typical cover crop weed suppression functions. The majority of crops are non-leguminous, such as buckwheat[4]. Many green manure crops are effective weed suppressors due to their deep rooting capabilities.
