During 3 years (1990-1992) the pot experiment on 15 soils with the red clover and Italian ryegrass were conducted. Each of soil was without Mg treatment or with treatment of 0.04 g Mg/1 kg of the soil. The soils were very differentiated in the content of various forms of magnesium (2.9-22.7 mg Mg/100 g of the soil), humus (0.9-2.7%) and soil particles <0.02 mm (6-25%). The content of different form of Mg in the soil (active, exchangeable, available after Schachtschabel and EUF and nonexchangeable) depended first of all upon thDuring 3 years (1990-1992) the pot experiment on 15 soils with the red clover and Italian ryegrass were conducted.

The content of different form of Mg in the soil (active, exchangeable, available after Schachtschabel and EUF and nonexchangeable) depended first of all upon the sorption capacity, the content, later on the humus and at least on the content of soil particles <0.02 mm. Application of magnesium increased the yields of red clover and Italian ryegrass when soil contained 1 3.5-4.5 mg of exchangeable magnesium per 100 g of the soil. The increase of yield of plants after Mg application could be predicted most accurately on the basis of the content of Mg (extractable in 0.01 M CaCl₂) and in smaller degree on the basis of the content of available detected by EUF, and Schachtschabel methods.e sorption capacity, the content, later on the humus and at least on the content of soil particles <0.02 mm.

During 3 years (1991-1993) on 3 soils the pot experiments with red clover and Italian ryegrass were conducted. Increased doses of magnesium (0; 0.2; 0.4 and 0.6 g Mg per pot with 6.5kg of the soil) were applied. The soils were differentiated in the content of humus (0.90—4.90%), particles <0.02 mm (13-27%), and exchangeable magnesium (2.6-9.5 mg) and calcium (17-212 mg per 100 g of the soil). On the soil with the smallest content of soil particles <0.02 mm, humus, and exchangeable Mg and Ca and the increase of yields under Mg treatment were the highest. The highest yields were also on soil with the largest amount of exchangeable Mg, but middle a of humus and soil particles <0.02 mm. Even by very different rates of magnesium fertilizer, sum of cations K + Mg + Ca, and the ratio of K:(Ca+Mg) in plants were similar. This ratio in red clover was more narrow (0.71) than in Italian ryegrass (1.69).
