SOIL CONDITIONER COMPOSITION FOR SALTY LAND WHICH USES ILLITE CAPABLE OF PREVENTING LACK OF REARING AND WITHER AFTER PLANTING TREES DUE TO ALKALI SOIL AND SALINE SOIL IN SALTY LAND OR RECLAIMED LAND AND A PLANTING METHOD BY USING THE SAME

摘要

PURPOSE: A soil conditioner composition for salty land and a planting method by using the same are provided to suppress inflow of sodium ions into salty water and to stably supply inorganic nutrient components necessary for planting while suppressing loss of long-term potassium ion of soil.;CONSTITUTION: A soil conditioner composition for salty land which uses illite comprises 20-50 wt% of illite powder, 20-50wt% of dihydrate gypsum (CaSO4.2H2O), 5-20wt% of vermiculite and 1-10wt% of xanthan gum. 1-10wt% of boronic acid based compound selected from boric acid, ammonium borate and boric acid esters is additionally added to the soil conditioner composition.;COPYRIGHT KIPO 2013;[Reference numerals] (A1,A6,A11,A16) Experimental group A; (A2,A7,A12,A17) Experimental group B; (A3,A8,A13,A18) Experimental group C; (A4,A9,A14,A19) Experimental group D; (A5,A10,A15,A20) Experimental group E; (BB) Acidity, PH; (CC) Organic matter OM(%); (DD) Exchaneable cation (ma/100g) NA+; (EE) Exchaneable cation (ma/100g) K+; (FF) Exchaneable cation (ma/100g) Ca++; (GG) Exchaneable cation (ma/100g) Mg++; (HH) Valid phosphoric acid (mg/kg)
