Nutrient management can help to improve the fertility of the soil and the amount of organic matter content, which improves soil structure and function. Tilling the soil, or tillage, is the breaking of soil, such as with a plough or harrow, to prepare the soil for new seeds. Tillage systems vary in intensity and disturbance.
A soil scientist examining horizons within a soil profile. Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils.
Soil management involves practices and techniques used to increase and maintain soil fertility, structure, and carbon sequestration, etc. [4] Soil management techniques are heavily utilized in agriculture, because of the need to regulate the various practices, such as tillage techniques, fertilizer application and crop rotation (among others ...
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 ...
Soil management tools include maintaining soil nutrient and organic matter levels, reduced tillage and increased cover. [231] These practices help to control erosion and maintain productivity during periods when moisture is available. Continued land abuse during droughts, however, increases land degradation.
The study also highlighted the need for a uniform definition of soil organic carbon sequestration among researchers. [54] The study concludes, "Additional investments in soil organic carbon (SOC) research is needed to understand better the agricultural management practices that are most likely to sequester SOC or at least retain more net SOC ...
Soil quality can be evaluated using the Soil Management Assessment Framework. [5] Soil quality in agricultural terms is measured on a scale of soil value (Bodenwertzahl) in Germany. [6] Soil quality is primarily measured by chemical, physical, and biological indicators because soil function cannot easily be measured directly. [7] Each of these ...
Soil Profile on Chalk at Seven Sisters Country Park, England. Pedology (from Greek: πέδον, pedon, "soil"; and λόγος, logos, "study") is a discipline within soil science which focuses on understanding and characterizing soil formation, evolution, and the theoretical frameworks for modeling soil bodies, often in the context of the natural environment.
