Water balance for agriculture production

Water is the most important component of agriculture production, especially during the dry seasons when all water sources are scarce yet water needs are very high. The Mekong river delta in Vietnam is the largest agricultural and aquacultural region in the country where about half of the Delta’s land area is used for rice and upland crop cultivation.

Regarding yield of the crops and growth regulation fertility of soil is most important but today’s scenario of agriculture farming in India is not care about it. Without any analysis farmer used unwanted and abundant quantity of fertilizer and water, both results reduce fertility of soil. For sustainable agriculture development and production, analysis, chemical composition, micronutrient, macronutrients and micro fauna from soil is must. Soil is an important natural resource and plays a crucial role in maintaining environmental balance.

Both biotic and abiotic stresses are major constrains to agricultural production. Under stress conditions, plant growth is affected by a number of factors such as hormonal and nutritional imbalance, ion toxicity, physiological disorders, susceptibility to diseases, etc. Plant growth under stress conditions may be enhanced by the application of microbial inoculation including plant growth promoting rhizobacteria (PGPR).

Setting up water-saving irrigation strategies is a major challenge farmer‟s face, in order to adapt to climate change and to improve water-use efficiency in crop productions. However, there is an increasing need to strategize and plan irrigation systems under varied climatic conditions to support efficient irrigation practices while maintaining and improving the sustainability of ground- water systems.

Water is a critical input for productivity enhancement especially of field crops. Its judicious and optimum use is needed utmost for realizing higher resource use efficiency and plugging gaps in production. Key technological interventions, which could alter or rectify the usage pattern or strategies in freshwater utilization in agriculture, are the need of the hour. Precision water management approach could help in conserving and making more-efficient use of scarce water resources through integrated management combined with selected external inputs/technologies.

The advance of chemicals in industry during the XX century gave rise to a number of highly aggressive compounds to human beings, and that altered the ecosystems balancing. Human population is inevitably exposed to environmental pollution through air-degraded products, water, the soil and food and their introduction into the food chain (Gomez et al, 2011). The use of pesticides has been recognized and accepted as an essential ingredient in the modern agriculture for the control of pests, which damage crops and as a result, they produce a severe loss in food production.
