Nitrogen fertilizer being applied to growing corn in a contoured, no-tilled field in Iowa.. Nutrient management is the science and practice directed to link soil, crop, weather, and hydrologic factors with cultural, irrigation, and soil and water conservation practices to achieve optimal nutrient use efficiency, crop yields, crop quality, and economic returns, while reducing off-site transport ...
Nitrogen leaching occurs when nitrogen compounds, primarily nitrates, move through the soil profile and enter groundwater, potentially contaminating drinking water sources. [2] To mitigate these environmental impacts, various nitrogen management strategies are employed in agriculture.
Energy efficiency is the goal of efforts to reduce the amount of energy required to provide products and services. The general term "energy efficiency in agriculture" reflects changes in technology, government policies, weather patterns, and farming management practices. There is not a single measure to describe, ensure, and improve energy ...
Extensive use of agrochemicals in agricultural practices has been found to cause environmental disturbances and public health hazards affecting food security and sustainability in agriculture. [22] Biofertilizers offers an alternative solution for such agrochemicals, and show yield increase of up to about 10–40% by increasing protein contents ...
Together with anaerobic condition, increases in soil water saturation can increase denitrification processes in the soil. Possible consequences are an increase in N 2 O emission, decreases in available nitrogen in soil and reduced efficiency of nitrogen usage by crops. [29] This may cause in an increase of fertilizer use. [9]
Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
A February 2011 article in the magazine Science Illustrated states, "In commercial agriculture, CEA can increase efficiency, reduce pests and diseases, and save resources. ... Replicating a conventional farm with computers and LED lights is expensive but proves cost-efficient in the long run by producing up to 20 times as much high-end ...
Agricultural productivity is an important component of food security. [4] Increasing agricultural productivity through sustainable practices can be an important way to decrease the amount of land needed for farming and slow environmental degradation and climate change through processes like deforestation.
