Technology of the main tillage of the abandoned fields

Abstract

The lands that turned out to be unclaimed for agrarian production pass into the category of waste, due to the spread of weeds on them. At the first stage, such lands pass through a wild grass stage with typical weed-field vegetation, where annual dicotyledons predominate, subsequently these plants are supplanted by perennial grasses, overgrown with shrubs and tree growth, and waste lands become uncultivated deposits. The presence of vegetation cover with a height of 1-1.7 m not only complicates the conduct of mechanical tillage, but also requires large amounts of energy. On lands left out of agricultural use, there is a noticeable change in soil properties. All agrochemical parameters of deposits have a lower value than arable land. On abandoned fields, along with a decrease in nutrients in the soil, there is a change in water and air conditions, which complicates the process of tilling. Entering abandoned fields in crop rotation for the production of agricultural products is an important economic problem of the day. The aim of the work is to develop the technology of the main tillage and dump plow for its implementation, ensuring the incorporation of tall plants in abandoned fields at low energy costs and high agrotechnical indicators.

Revisiting weed infestation of agricultural lands from zones near utility poles

“…In conducting field works in the power lines zones, the question of compensation payments to landowners and land users from energy companies is often raised. The main rationale for these payments is the assertion that there are limited possibilities for cultivation of soil around utility poles constructed for power lines support, which results in weeds centers [1]. As a result, the general background of agricultural lands infestation increases and leads to reduction in yields and escalation of weed control costs [2,3,4].…”
