PEAT NUTRIENT MIXTURE Russian patent published in 2003 - IPC

FIELD: peat processing technology. SUBSTANCE: nutrient mixture contains peat, mineral components and trace elements. Mixture contains sand additionally and following mineral components: powdered lime and/or dolomite, simple or binary superphosphate, ammonium nitrate, potassium sulfate, magnesium sulfate. Mixture contains the following trace elements: copper sulfate, zinc sulfate, iron citric-ammonium, ammonium molybdate, borax or boric acid, manganese sulfate. Ratio of component, kg per 100 l of mixture: peat, 75.0-85.0; sand, 8.0-25.0; powdered lime and/or dolomite, 7.0-11.0; simple or binary superphosphate, 0.3-3.0; ammonium nitrate, 0.15-0.85; potassium sulfate, 0.4-1.0; magnesium sulfate, 0.1-0.5; copper sulfate, 0.005-0.030; zinc sulfate, 0.003- 0.007; iron citric-ammonium, 0.015-0.03; ammonium molybdate, 0.001-0.006; borax or boric acid, 0.006-0.0012; manganese sulfate, 0.003-0.008; water, the balance. Ready product shows the following composition (form available for plants), mg/l: nitrogen (NH₄ + NO₃), 70-275; phosphorus (P₂O₅), 100-250; potassium (K₂O), 150-500; moisture mass part is 65%, not above; acidity: pH value of saline substance is from 5.0 to 6.5. Invention provides creation of the novel peat-base composition of nutrient mixture as soil and can be used for growing different species of flower, berry, vegetable, decorative cultures, room plants and for topical addition in vegetable cultures planting. EFFECT: expanded assortment of peat nutrient mixtures, reduced cost, simplified preparing and storage of peat nutrient mixture. 3 ex
