Agrophysics is a branch of science bordering on agronomy and physics, whose objects of study are the agroecosystem - the biological objects, biotope and biocoenosis affected by human activity, studied and described using the methods of physical sciences.
NCERT has a comprehensive extension program in which departments of the National Institute of Education, Regional Institute of Education, Central Institute of Vocational Education, and field coaches' offices in the states are engaged in activities. Several programs are organized in rural and backward areas to reach out to functionaries in these ...
Agriculture concerns techniques, including the application of agronomic research. Agronomy is research and development related to studying and improving plant-based crops. Geoponics is the science of cultivating the earth. [10] Hydroponics involves growing plants without soil, by using water-based mineral nutrient solutions in an artificial ...
Agricultural chemistry often aims at preserving or increasing the fertility of soil with the goals of maintaining or improving the agricultural yield and improving the quality of the crop. Soils are analyzed with attention to the inorganic matter (minerals), which comprise most of the mass of dry soil, and organic matter, which consists of ...
Indian agriculture benefited from the developments made in the field of biotechnology, for which the Department of Biotechnology was created in 1986 under the Ministry of Science and Technology. [18] Both the Indian private sector and the government have invested in the medical and agricultural applications of biotechnology. [18]
The Soil Conservation Service worked with state governments and universities with established agriculture programs, such as the University of Nebraska, to promote the method to farmers. By 1938, the introduction of new agricultural techniques, such as contour plowing, had reduced soil loss by 65% despite the continuation of the drought.
The dry bulk density of a soil greatly depends on the mineral assemblage making up the soil and on its degree of compaction.The density of quartz is around 2.65 g/cm 3 but the dry bulk density of a soil can be less than half that value.
