One of the most difficult issues at present is the land market. In the political direction, there is an extensive discussion about the land market, but almost no one raises the issue of its preservation for future generations. Many scientists, especially soil scientists, warn of the gradual loss of its fertile potential due to a sharp decrease in the soil of the main indicator fertility - humus. As a result of conducting intensive technologies in crop production in the agro-industrial complex, the main purpose of which is to obtain large profits, the recommended crop rotations are not followed, as crops such as wheat, corn, soybeans and sunflowers are grown.

With this attitude to the land, it will lose fertility in the near future, due to a sharp drop in humus. In many publications of soil scientists over the past 20 years, humus has decreased by almost 2% on average, while in the previous 100 years it has decreased by 1.5-2%.

Thus, it is urgent to change the adopted technology to soil-preserving, which, along with the preservation of the soil with their proper implementation are not inferior to the yield of industrial technologies.

It is necessary to pay attention to how energy and soil-saving technologies are used in most countries of America, Canada, and Europe. These are No-Till and Strip-till technologies. These technologies are based on minimal tillage with mandatory high-quality soil cover with crop residues. The technology is complex and requires proper implementation in the presence of appropriate machines.

In Vinnytsia National Agrarian University has developed a design of units most accessible to farms Strip-till strip tillage technologies.
