How do the microbes help to increase soil fertility?
Answers
Answer:
microbes is also helps in a biological nitrogen fixation
Explanation:
it receives nitrogen from the atmosphere and change them into soluble form then the plants receives nitrogen by root from soil which results in its growth . BY THIS process the plants also replenish and maintains the nitrogen level in the soil.
Some microbes changes the garbage waste into humus which works as like as manures
Micro-organisms are the most essential resource for a farmer because they nourish soil with essential nutrients. Soil contains numerous minerals in forms which plants cannot absorb directly. Microbes like fungi and bacteria with the help of their enzymatic machinery break down these minerals into forms that can be absorbed by crops.
The best example is mineralization of phosphorus, which is an essential mineral for plant growth. When present in its inorganic form, plants cannot absorb it. Micro-organisms from soil solubilize the insoluble phosphate and make it available for plants.
Nitrogen is another important element required for plant growth. Our atmosphere contains 78.09 per cent of nitrogen. Despite its abundance, neither plants nor animals have the ability to consume this nitrogen for their nutrition. Microbes fix the atmospheric nitrogen and make it available for all living forms.
Along with essential elements, microbes also provide one of the most influential factors required for overall development of plants - plant hormones. Some of these plant hormones play crucial roles in seed formation, growth and ripening. These hormones also impart immunity against invading pests.
Lastly, soil micro-organisms, especially fungi, form mesh-like structures with the roots of plants. By residing along with roots, they provide plants with nutrients and also help maintain moisture. This builds capacity in plants to withstand water scarcity and also help soil become resistant towards dehydration.
