Agronomy is the science and technology of producing and using plants by agriculture for food, fuel, fiber, chemicals, recreation, or land conservation. Agronomy has come to include research of plant genetics , plant physiology , meteorology , and soil science .
Conservation agriculture (CA) can be defined by a statement given by the Food and Agriculture Organization of the United Nations as "Conservation Agriculture (CA) is a farming system that can prevent losses of arable land while regenerating degraded lands.It promotes minimum soil disturbance (i.e. no-till farming), maintenance of a permanent soil cover, and diversification of plant species.
The rows formed slow surface water run-off during rainstorms to prevent soil erosion and allow the water time to infiltrate into the soil. Soil conservation is the prevention of loss of the topmost layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil ...
Agronomy – science and technology of producing and using plants for food, fuel, feed, fiber, and reclamation.. Organic gardening – science and art of growing fruits, vegetables, flowers, or ornamental plants by following the essential principles of organic agriculture in soil building and conservation, pest management, and heirloom variety preservation.
In some systems residues are burned. This is a fast and cheap way to clear a field in preparation for the next planting, and can assist with pest control, but has a number of drawbacks: organic matter (carbon) is lost from the system, soil is exposed and becomes more susceptible to erosion, and the smoke produced is an atmospheric pollutant.

The technocentric approach argues that sustainability can be attained through a variety of strategies, from the view that state-led modification of the industrial system like conservation-oriented farming systems should be implemented, to the argument that biotechnology is the best way to meet the increasing demand for food.
Agricultural soil science is a branch of soil science that deals with the study of edaphic conditions as they relate to the production of food and fiber. In this context, it is also a constituent of the field of agronomy and is thus also described as soil agronomy .
Sustainable land management (SLM) is a process in a charged environment between environmental protection and the guarantee claim of ecosystem services on the one hand. On the other hand, it is about productivity of agriculture and forestry with respect to demographic growth and increasing pressure in land use.
