14 Oct Contribution of bio-inoculants in agriculture sector
कृषि क्षेत्र में जैव-आवेगों का योगदान The increase in the world's population, coupled with the limitations in the world's supply of natural resources and widespread degeneration of the environment presents a major challenge to agriculturalists. Chemical fertilizer is used to give the plant nutrient requirements within a short period to get faster results. Newly improved varieties of crops need high proportions of fertilizer. But chemical fertilizer has certain limitations and entails a lot of disadvantages. No doubt, the application of chemical fertilizer provides nutrition in high concentration in the soil and plants. When chemical fertilizer is applied, the entire contents would not be absorbed by the plants and the remaining parts would react in the soil. Part of it would be washed away and would contaminate water and some part of it would evaporate to the atmosphere; thereby the environment is polluted. Intense activity is involved in efforts to create plants that by themselves are able to fix nitrogen from the atmosphere i.e convert nitrogen gas into nitrates that can be used by plant’s metabolic machinery. At present, only certain plants called legumes are naturally able to do so and even legumes require the aid of symbiotic bacteria. Further soil is reservoir of nutrients. But in some cases the nutrient remain in fixed forms which...
