METHOD OF LONG-STEMMED FLAX CULTURING Russian patent published in 1999 - IPC

FIELD: agriculture. SUBSTANCE: method involves liming acid soils with ash residue of shale thermic processing with solid heat-carrier, treatment of soil, addition of mineral fertilizing, sowing and protection of planting against weeds, pests and pathogens. Liming is carried out with an ash residue of burning unit UTT-3000 containing, %: CaO 30.5-43.6; MgCO₃ 6.2-12.5; potassium and iron up to 5; phosphorus and sulfur 1.5, and the following components, mg/kg: Mn 1200; Mo 0.56-6.14; Zn 54.6-260; Cu 22-44; sulfide sulfur, thiosulfides and toxic organogenic compounds - up to 0.3-1.9%. Invention can be used for the long-stemmed flax culturing in acid soils. EFFECT: decreased damage of sowing with bacteriosis, enhanced quality of flax production. 1 tbl
