文摘
The reclamation resource is an increase in crop yield under the influence of forest shelterbelts. The reclamation effectiveness of pine plantations exceeds that of deciduous plantations formed by ash, honey locust, and elm. The greatest value of the reclamation resource is characteristic of stands with a width of 15–18 m at the age of 80 years. One-ha forest belts can form a zone of reclamation effect with an area of 9 ha in which it is possible to obtain an increase in winter wheat yield up to 1.6 t at a cost of up to RUR 15300.
