Historically, a common method described in literature was "to sow salt." In practice this does not actually work, as salt is soluable and easily carried away by rain.
Soil is partially sterlized through the use of herbicides, such as Agent Orange or Round Up. Covering patches of soil with black plastic is another method of sterilization that does not require adding chemicals. Herbicides are often sprayed along road ways and side walks to prevent the roots of trees and brush from cracking the concrete or pavement. Of course, covering land with asphalt is another effective "sterilization" technique.
Finally, if one can afford the energy, running soil through an autoclave will sterilize it. This might be done for certain Biology experiments in university laboratories. Soil is not typically autoclaved for regular agricultural use.

Three methods which farmers use to conserve soil is Contour Plowing, Conservation Plowing,and Crop Rotation.
Soil conservation is methods of ways to protect the soil from being moved to different places.

The three types of microbial control methods are: disinfection, sterilization, and commerical sterilization.
Sterilization is the complete removal of all microorganisms ( e.g: becteria, virsues,...etc) from the surface area of 'anything' While Disinfection is an in-complete removal of microorganisms from" inanimate or nonliving" objects. and has three distinctive levels. High level disinfection, intermediate level, and low level. Both sterilization and disinfection have chemical and physical methods. And since the question is about the methods of sterilization then there are: physical methods: Heating and radiation chemical methods: some chemicals like 'Etheline Dioxide', or by chemical evaporation.

The purpose of the Sterilization Process is the destruction of all pathogenic organisms together with spoilage/non-pathogenic microorganisms, to achieve the Safe Preservation at Room Temperature of treated products.

Direct sterilization is the destruction of a normal functioning, healthy organ to prevent future conception of children. There are two methods of direct sterilization; a male vasectomy and the ligation of the fallopian tubes of a woman.
It's tubal ligation for women and vasectomy for men.
Because CJD is hardy, it remains infectious for years in a dried state and resists all routine sterilization and disinfection procedure. Nadia real
Sterilization by various means such as steam sterilization (autoclave), dry heat (hot air oven), radiation (ionising & non-ionising),chemical methods etc. kills microorganisms.

Cold sterilization, where the instruments are put in a chemical solution, and it takes around 12 hours for them to become sterilized. Heated sterilization, which is done in an autoclave, under high heat and high pressure. It only takes a few minutes for the instruments to be sterilized.
