2. Soil management - Wikipedia

   en.wikipedia.org/wiki/Soil_management

   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.

3. Soil conditioner - Wikipedia

   en.wikipedia.org/wiki/Soil_conditioner

   The soil conditioning technology was presented at a symposium on "Improvement of Soil Structure" held in Philadelphia, Pennsylvania on December 29, 1951. The technology was strongly documented and was published in the June 1952 issue of the journal Soil Science , volume 73, June 1952 that was dedicated to polymeric soil conditioners.

4. Vacuum consolidation - Wikipedia

   en.wikipedia.org/wiki/Vacuum_consolidation

   Vacuum consolidation (or vacuum preloading) is a soft soil improvement method that has been successfully used by geotechnical engineers and specialists of ground improvement companies in countries such as Australia, China, Korea, Thailand and France for soil improvement or land reclamation. [1]

5. Soil regeneration - Wikipedia

   en.wikipedia.org/wiki/Soil_regeneration

   Organic amendments improve biological activity, water permeability, and soil structure. [4] Mulch , for example, reduces erosion and helps to maintain the temperature of the soil. [ 3 ] Compost is rich in organic matter, [ 4 ] it is composed of decomposed matter such as food, vegetation, and animal wastes. [ 3 ]

6. Soil salinity control - Wikipedia

   en.wikipedia.org/wiki/Soil_salinity_control

   Soil salinity control refers to controlling the process and progress of soil salinity to prevent soil degradation by salination and reclamation of already salty (saline) soils. Soil reclamation is also known as soil improvement, rehabilitation, remediation , recuperation, or amelioration.

7. Soil fertility - Wikipedia

   en.wikipedia.org/wiki/Soil_fertility

   Soil scientists use the capital letters O, A, B, C, and E to identify the master horizons, and lowercase letters for distinctions of these horizons. Most soils have three major horizons—the surface horizon (A), the subsoil (B), and the substratum (C). Some soils have an organic horizon (O) on the surface, but this horizon can also be buried.
