In-situ conservation is the on-site conservation or the conservation of genetic resources in natural populations of plant or animal species, such as forest genetic resources in natural populations of tree species. [1] This process protects the inhabitants and ensures the sustainability of the environment and ecosystem.
Example research projects are to examine the biogeochemistry and microbial ecology of septic drain field soils used to treat domestic wastewater, the role of anecic earthworms in controlling the movement of water and nitrogen cycle in agricultural soils, and the assessment of soil quality in turf production.

The benefits were increased plant growth, increased phosphorus uptake [105] and soil nitrogen content, higher soil organic matter content, and soil aggregation, attributed to higher legume nodulation in the presence of AM fungi, better water infiltration, and soil aeration due to soil aggregation.

The term later expanded beyond catalysis and is now applied across various disciplines of materials science, alongside the opposite designation ex situ. [4]: 1534 For example, in situ describes the study of a sample maintained in a steady state [c] condition within a controlled environment, where specific parameters such as temperature or ...
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.
In-situ conservation of seed-producing plant species is another conservation strategy. In-situ conservation involves the creation of National Parks, National Forests, and National Wildlife Refuges as a way of preserving the natural habitat of the targeted seed-producing organisms. In-situ conservation of agricultural resources is performed on-farm.
Plant conservation strategies generally combine elements of conservation on farm (as part of the crop production cycle, where it continues to evolve and support farmer needs), ex situ (for example in gene banks or field collections as seed or tissue samples) or in situ (where they grow in the wild or protected areas).
It is known that the biocrust does play a role in the absorption and retention of moisture in the soil. In arid and semi-arid environments biocrust can cover over 70% of the soil not being covered by plants, indicating that the relationship between soil, water, and biocrust is extremely pertinent to these environments.
