Farmable land talks are not only achieved through preventive and curative remedies to control soil erosion, but also through the use of innovative agricultural technologies.
i) Organic farming:
No modem farming system is completely self-reliant, and if the yield is maintained, then everyone has to rely on some forms of nutrient input. The nitrogen fixation in the soil provides an attractive alternate nitrogen source for soil from nitrogen fixation in the legume root node.
Increase in organic forms of fertilizers such as cow dung agricultural waste, improves soil nutrient status. It can also help in reducing toxic effects of prolonged use of inorganic nitrogen fertilizers in the past.
Microorganisms are important components of fertile soil. They participate in the development of soil structure, add available nutritious elements and improve the soil condition of the soil. If an important microorganism is absent from the soil then it may be necessary to present or apply that organism to the soil.
Occasionally, in an effort to supply an indigenous organism, the use of inoculation can also be used, which is of poor quality. This is more difficult to achieve. Introduction of the root nodule bacteria in the soil, usually represents the initial efforts on the use of bio-fertilizers by pasting a carrier substance on league seeds.
In order to improve the nutritional status of crop fields, today a large variety of microorganisms applied on suitable carrier substances are used as biofertilizers. The advantage of using bio fertilizers on chemical fertilizers is that they produce fertilizers in the place where nutrients are needed. This is contrary to chemical fertilizers, which should be manufactured in the factory and then transported to the agricultural areas.
In addition, organic fertilizers produce only the necessary quantity and provide such quantity to the plants in the filed. Whereas, in the case of chemically remaining areas, unused fertilizers are taken out and the cause of eutrophication of water bodies is made.
Once established in one area, organic fertilizers are not required for later anonymity, whereas chemical fertilizers should be combined with each crop and perhaps increasing quantity every year. The use of organic fertilizers can tolerate the biological control of plant root pathogen, but non-surviving chemical fertilizers do not provide protection from the pathogen to the plants. Organic fertilizers thus provide environment on chemical fertilizers for the modern agro-ecosystem and provide safe alternative to the environment.
iii) Biological Pest Control:
Another application of microbiology finds its place in protecting plants against pests. Pests generally have enemies in nature but they remain inactive because the development of highly agricultural production insecticides is encouraged. Organic insect control wants to set up this ecological tool to pay for the survival opportunities of insect population through biological agents.
It is taken care to see that the agent should be specific to the insect, that is, it should only destroy the insect and not be harmed by any other organization living nearby. You know that the non-specificity of chemical pest control agents leads to the death of non-targeted organisms. There is no such risk in organic pest control.
One good point about biological control is that biological agents die a natural death within a short period of time. You know that chemical pesticides are not biodegradable and have long been active for a long time after their target pests are destroyed and proved to be harmful to mankind. Which means that chemical agents are damaged for the environment for years to come.
In addition, they are likely to enter food chains and poisoning humans, while biological agents are not likely to harm humans on this account. Biological control of pests is therefore an ecological sound alternative for chemical pest control.
The first real application of biological control or insect was the discovery of the milk beetle of the Japanese Beetle. In this disease, seeds of bacteria are included, in which there are toxic toxic substances for this beetle. As a result of recent research, this bacterial spark has commercialization, in which crystalline endotoxin is an active ingredient for the control of beetle larvae.
Another group of toxins made by the subspecies of this bacterium kills mosquitoes and blackflies too. Some 1,500 naturally occurring microorganisms or microbial by-products have been identified as potentially useful insecticidal agents. Thus, the biological control of pests is an old practice and should now be adopted by our indigenous farmers.
In the race to save agricultural plants from insects, high organisms are also effective in the form of microorganisms. Some examples are as follows: The first large scale use of biological control was done against the pest introduced by mistake of citrus fruit. This pest, Cotton-Cushion Scale (Icaria Purchase) seriously threatens the citrus fruit industry. In this case, a beetle was introduced as a hunter in 1888. The effect of this hunter was that the insect had ended within two years. The name of the control agent is Ladybird Beetle, and this agent still effectively controls the insect.
Another example is the recovery of 20 million hectares of Australian grassland which comes out from thorn pear cactus. An insect kite was introduced to control this weed. The larvae of this kite was established within a few years on the cattles of the muscles of the leaves and kites. After some time, most cactus weed was destroyed, so that land could be used once for agriculture.
