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.
Soil management is the application of operations, practices, and treatments to protect soil and enhance its performance (such as soil fertility or soil mechanics). It includes soil conservation , soil amendment , and optimal soil health .
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.
A myriad of practices can be used to increase soil organic content, like cover cropping, composting, and crop rotation to improve soil fertility, water retention, and ability to resist soil erosion. Research supports that soil microbial diversity is critical for maintaining fertility and resilience against the changing climate, and regenerative ...
A study showed increased soil fertility following the addition of mature compost to a clay soil. [171] High soil tannin content can cause nitrogen to be sequestered as resistant tannin-protein complexes. [172] [173] Humus formation is a process dependent on the amount of plant material added each year and the type of base soil.
Cover crops manage soil erosion, soil fertility, soil quality, water, weeds, pests, diseases, biodiversity and wildlife in an agroecosystem—an ecological system managed and shaped by humans. Cover crops can increase microbial activity in the soil, which has a positive effect on nitrogen availability, nitrogen uptake in target crops, and crop ...
Soil bulk density is equal to the dry mass of the soil divided by the volume of the soil; i.e., it includes air space and organic materials of the soil volume. Thereby soil bulk density is always less than soil particle density and is a good indicator of soil compaction. [ 47 ]
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 contamination
