The aim of the paper is to recapitulate the results of the lysimetric experiment obtained during 1977-94 on the balance of phosphorus in relation to the soil kind and NPK fertilization level. Double and triple NPK rates significantly increased crop yields and also, to a smaller degree phosphorus uptake by plants. After 16 years of the experiment the phosphorus balance was negative at single rates of fertilization, and it was marked positive at the triple NPK rates
