How is nitrogen from the atmosphere brought into the ground?
Nitrogen in the atmosphere is converted into nitrogen in the soil by a process called nitrogen fixation, which is carried out by a number of different types of bacteria. Some of these bacteria grow on the roots of certain plants, such as clover, alfalfa, and peanuts, and provide nitrogen to the plant and the soil. ----------------------------------------- Lightning also causes some atmospheric nitrogen to be converted into oxides of nitrogen. These dissolve in rain water and are brought to the ground in the rain.
Some farmers feel that lightning helps produce a better crop.What is the scientific basis for belief?
The belief among farmers that lightning helps produce a better crop has no basis in science. This is simple considered an old wives tale. Perhaps during years of heavy lightning, farmers give the crops extra attention being motivated by the belief and this results in increased production.
What do many crops deplete from the soil?
Many crops deplete essential nutrients from the soil, such as nitrogen, phosphorus, and potassium. Continuous farming of the same crop can lead to nutrient depletion in the soil, which may require fertilizers or crop rotation to replenish the nutrients.
How can a farmer protect the nitrogen content or soil?
Farmers can protect the nitrogen content in soil by practicing crop rotation, using cover crops, and reducing the amount of synthetic fertilizers applied. These practices help to maintain a healthy nitrogen balance in the soil, which is essential for plant growth and soil fertility.
Cure for too much nitrogen in soil?
Nitrogen is water soluble, the easiest way to do that is to water the plants with straight water for a few times, especially if you are using nutrients. If you are growing outdoors, then flood the plants twice. Over water them a couple of times, and the N should work itself out.
What makes agriculture land a major source of nitrogen fixation?
Agricultural land is a major source of nitrogen fixation because of the cultivation of leguminous crops that have symbiotic relationships with nitrogen-fixing bacteria in their roots. These bacteria convert atmospheric nitrogen into a form that plants can use, thereby enriching the soil with nitrogen. Additionally, the use of fertilizers and manure in agriculture also contributes to nitrogen fixation in the soil.
Why must farmers constantly and nitrogen when this element recycles naturally?
Farmers need to constantly add nitrogen to their fields because crops remove nitrogen from the soil as they grow. While nitrogen does cycle naturally through processes like nitrogen fixation and decomposition, the rate at which crops deplete nitrogen often outpaces natural recycling, leading to nutrient depletion in the soil. By adding nitrogen through fertilizers, farmers ensure that their crops have an adequate supply for optimal growth.
How is nitrogen fixation helpful to crops?
Because elemental nitrogen is unusable by plants. It must be converted in the soil to a usable form and adsorbed by soil particles for plants to be able to utilize it.
What 2 things an increase the amount of nitrogen in the nitrogen cycle?
Two factors that can increase the amount of nitrogen in the nitrogen cycle are the use of nitrogen-based fertilizers and the process of nitrogen fixation. Nitrogen-based fertilizers, when applied to crops, enhance soil nitrogen levels, promoting plant growth. Additionally, nitrogen-fixing bacteria in the soil or in the root nodules of legumes convert atmospheric nitrogen into a form that plants can use, naturally enriching the nitrogen content in the ecosystem.

Producing genetically-engineered major crops to carry out nitrogen fixation has been hampered because?
the bacteria do not function properly when they are introduced into the plants.

Why is nitrogen fixation important to living things?
Plants need nitrogen in order to grow. Nitrogen is abundant in the earth's atmosphere, but plants cannot use it in that particular form (nitrogen gas). Certain bacteria which reside on some plant roots are able to change atmospheric nitrogen into a form that plants can use (ammonia).
Why is nitrogen used in fertiliser?
Nitrogen is very important to many crops; without nitrogen the production is decreased.
Why do farmer need more nitrogen than carbon to grow their crops?
Plants draw carbon dioxide out of their environment and use it to build biomass, as in carbon respiration or the Calvin cycle, a process of carbon fixation. Nitrogen fixation, natural and synthetic, is essential for all forms of life because nitrogen is required to biosynthesize basic building blocks of plants, animals and other life forms, e.g., nucleotides for DNA and RNA and amino acids for proteins. Therefore nitrogen fixation is essential for agriculture and the manufacture of fertilizer.
How can I improve the nitrogen content in soil?
To improve nitrogen content in soil, you can use nitrogen-rich fertilizers, plant nitrogen-fixing crops like legumes, rotate crops, and add organic matter like compost or manure.
How does the legumes impact the nitrogen cycle?
Legumes play a crucial role in the nitrogen cycle through a process called nitrogen fixation. They host symbiotic bacteria, such as Rhizobium, in their root nodules, which convert atmospheric nitrogen into ammonia, a form that plants can use. This natural fertilization enhances soil fertility, reducing the need for synthetic fertilizers. Additionally, when legumes decompose or are incorporated into the soil, they release nitrogen, further enriching the soil and benefiting subsequent crops.
