Due to the short life of valuable Papilionaceous plants in the grassland greenness growth, the effect of soil conditions on these species was investigated. The research was carried out in 1993-1995 on the wane meadows of the Lublin Upland. Relations of pH and soil nutrient content on the Papilionaceous content in the greenness growth and the content of macro- and microelements in fodder was analysed. The research showed that Papilionaceous occurrence was clearly related to the soil kind, reaction, and phosphorus and magnesium content. The collected greenness growth contained too little P, Mg, Cu, and Zn. Only the pH and Mg, out of the investigated soil components, affected the content of some individual elements in the plants.
