Why farmers do not apply nitrogenous fertilizers during cultivation of leguminous crop?

Why farmers do not apply nitrogenous fertilizers during cultivation of leguminous crop?

The nitrogen fixed gets into the soil and make it fertile. Leguminous plants utilise some of the nitrogen compounds, leaving behind the rest to enrich the soil. So farmers do not add nitrogenous fertilisers to soil in which leguminous plants are grown.

Why farmers who cultivate gram crops do not add nitrogenous fertilizers to the soil?

do not apply nitrogenous fertilisers during cultivation. Explanation: Plants such as grams and pulses have a special type of bacteria in their roots which transforms atmospheric nitrogen into compound. and therefore there is no need of nitrogenous fertilizers.

Which crop does not require nitrogenous fertilizers examples?

A legume crop does not require nitrogenous fertilizers because its roots have root nodules that have nitrogenous bacteria called Rhizobium.

Why do farmers add nitrogen fertilizers?

To be used for growing, nitrogen needs to be combined with hydrogen to make ammonia. When it comes to growing healthy, mature plants, nitrogen is necessary because it’s a part of the chlorophyll molecule. Using the process of photosynthesis, chlorophyll helps plants create food they can use to grow.

Is it not necessary to add nitrogenous fertilizers for the cultivation of pulses?

But farmers who cultivate pulse crops like green gram, Bengal gram, black gram, etc. do not apply nitrogenous fertilizers during cultivation.

Why is it not necessary to add nitrogenous fertilizers for the cultivation of pulses leguminous Class 9?

Here’s your answer mate : Legume crops contain the nitrogen fixing bacteria (Rhizobium spp.) These bacteria fix atmospheric nitrogen into nitrates for the plant use. Hence, supply of nitrogenous fertilizers to the leguminous crops is not necessary.

Why farmers do not apply nitrogenous fertilizers during cultivation Class 7?

do not apply nitrogenous fertilizers during cultivation because these crops have rhizobium bacteria. Roots of pulses (leguminous plants) have a symbiotic association with a bacterium called Rhizobium which fixes nitrogen. Hence, farmers need not use nitrogenous fertilisers.

Which of the following crops does not require more nitrogen fertilizers Maize Paddy clover Berseem sugarcane?

Berseem clover does’t required more nitrogen fertilizers. Because Berseem clover is an erect-growing, good nitrogen-fixing, annual legume with ablong, slightly-hairy leaflets lacking a watermark.

Why is Azolla a Biofertilizer?

Azolla consists of cyanobacteria which are used as a biofertilizer. The cyanobacteria produce a range of toxins which are dangerous for the human and animals are known as cyanotoxins. It contributes nitrogen up to 60 kg and enriches the soil with organic matter.

Why is it not necessary to add nitrogenous fertilizers for the cultivation of pulses?

because pulses are leguminious plants. they have a bacteria on their root nodules which convert atmospheric nitrogen into nitrogenous compounds which was later absorbed by plant . they gain enough nitrogen for that so the farmers didnt need to apply nitrogenous fertilizer seperately.

Why are NPK fertilisers important to farmers?

Fertilisers provide elements needed by plants to grow well, such as nitrogen, phosphorus and potassium. They can make crops grow faster and bigger so that yields are increased. The compounds used must be water-soluble so plants can absorb them through their roots.

Why farmers who cultivate crops like green gram Bengal gram black gram etc do not use fertilisers during cultivation?

Leguminous plants like green gram, Bengal gram and black gram have enough root hairs and root legumes for the optimal growth of the Rhizobium bacteria. Hence, farmers do not apply nitrogenous fertilizers during cultivation.
