Modern agriculture is an evolving approach with innovations in farming practices that helps in increasing agricultural efficiency and reduce the loss of natural resources. By applying this modern technology, farmers are gaining more profits and able to increase their productivity of field.
Some of the modern techniques like selected variety of hybrid seeds of a single crop; bio-fertilizers and bio-pesticides; technologically advanced equipment and energy subsidies in the form of irrigation water are commonly employed by the farmers. The sensors used to detect moisture in the soil help farmers to create irrigation systems for crops based on soil moisture and temperature. Working in low visibility field conditions like rain,dust and fog is possible with the help of modern technologies. Agricultural robots automate agricultural processes of fruit picking, crop harvesting, soil maintenance, irrigation, ploughing, planting, weeding and others. These robots automate slow and repetitive tasks for farmers to ensure focus on improving overall production yields. Land-augmenting technological changes involve technical, chemical and biological modifications to beintroduced in agriculture.
