METHOD FOR PRIMARY TILLAGE OF USED PEAT Russian patent published in 2004 - IPC

Abstract RU 2222125 C1

FIELD: agriculture and forestry, in particular, reclamation of used peat for plant growing and forestation. SUBSTANCE: method involves leveling peat surface before plowing operation; providing breaking plowing and laying turned layers of peat and underlying ground layers one onto another with inclination of 40-70 deg to horizontal layer; determining depth of mineral ground to be plowed through from formula: Hgr = [Hp•ρgr•(Accm

-Acp
)]/[ρgr•(Acgr
-Accm
)], where Hgr is thickness of plowed-through mineral ground, m; Hp is thickness of residual peat layer after leveling operation, m; ρp is peat density, kg/cu.m; ρgr is density of mineral ground, kg/cu.m; Acp
 is peat cinder content, %; Acgr
 is cinder content of underlying layer, %; Accm
 is cinder content of peat and underlying layer mixture, %. EFFECT: increased efficiency in reclaiming of used peat soils. 2 cl, 1 tbl
