Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality. [3] It also refers to the soil's ability to supply plant/crop nutrients in the right quantities and qualities over a sustained period of time.

A soil test is a laboratory or in-situ analysis to determine the chemical, physical or biological characteristics of a soil. Possibly the most widely conducted soil tests are those performed to estimate the plant-available concentrations of nutrients in order to provide fertilizer recommendations in agriculture.
Soil texture triangle showing the USDA classification system based on grain size Map of global soil regions from the USDA. For soil resources, experience has shown that a natural system approach to classification, i.e. grouping soils by their intrinsic property (soil morphology), behaviour, or genesis, results in classes that can be interpreted for many diverse uses.
Regenerative agriculture is a conservation and rehabilitation approach to food and farming systems. It focuses on topsoil regeneration, increasing biodiversity, [1] improving the water cycle, [2] enhancing ecosystem services, supporting biosequestration, [3] increasing resilience to climate change, and strengthening the health and vitality of farm soil.
V. Dokuchaev with chernozem The scientific basis of soil science as a natural science was established by the classical works of Vasily V. Dokuchaev.Previously, soil had been considered a product of physicochemical transformations of rocks, a dead substrate from which plants derive nutritious mineral elements.
Research Evaluation is a quarterly peer-reviewed academic journal covering the "evaluation of activities concerned with scientific research, technological development and innovation". [1] It was established in 1991 and is published by Oxford University Press .
For instance, soil fertility in Paraiba, Brazil is generally low. To rectify this, animal manure is often used to supply agricultural crops with nutrients. [9] However, researchers in Brazil hypothesized that planting and incorporating Crotalaria juncea with animal manure could enhance the nutrient mineralization pattern for agricultural crops. [9]
