Bezpośrednie i następcze działanie wzrastajacych dawek dolomitu na glebie silnie kwaśnej

On loamy sand, with low content of humus, strongly acid (pHKCl 3.9), without application of lime during last tens of year doses of dolomite limestone according 0; 1; 2 and 3 Hh in pot experiment were applied. During 3 following years after use of dolomite yields of barley and triticale, their chemical composition and some more important physicochemical properties of soil were investigated. In circumstances of losses of Ca and Mg it is enough to apply lime according single Hh. Higher doses of lime only slightly improve properties of soil and do not affect the yields. In straw of studied cereals the increase of Mg and P and decrease of the content of K, Ca, Mn and Fe was observed. On the other hand in grain only slight increase of Mg and decrease of the content of Mn was found.
