Zusammenfassung: | The invention relates to a process for treating an acid soil for cultivating cereals and industrial plants. According to the invention, the process consists in ameliorating acid soils of the reddish preluvosoil type by applying, before planting, a dose of 3 t/ha steel slag resulting from secondary steel refining, which has an average composition of 20.7% SiO, 10% MgO, 55.5% CaO, 6.1% AlO, 0.74% MnO, 0.3% TiO, 1.59% SO, 3.53% F, 0.01...0.04% potassium, phosphorus, vanadium and chromium oxides, with a return period of 3...4 years, providing improved physical and chemical properties of agricultural soil.
Invenţia se referă la un procedeu de tratare a unui sol acid pentru cultivarea cerealelor şi plantelor tehnice. Procedeul, conform invenţiei, constă în ameliorarea solului acid de tip preluvosol roşcat, prin aplicarea, înainte de plantare, a unei doze de 3 t/ha zgură de oţel rezultată de la rafinarea secundară a oţelului, având o compoziţie medie de 20,7% SiO, 10% MgO, 55,5% CaO, 6,1% AlO, 0,74% MnO, 0,3% TiO, 1,59% SO, 3,53% F, 0,01...0,04% oxizi de potasiu, fosfor, vanadiu şi crom, cu o perioadă de revenire de 3...4 ani, asigurând o îmbunătăţire a proprietăţilor chimice şi fizice ale solului agricol. |
