Experiences on studying influence of acidity level of sod-podzolic light loamy soil on fibre flax yield and its quality have been conducted in 2005-2006 in collective Suvorov-farm Uzdensk district Minsk region. It is established that prevalence chlorosis in flax crops depends on acidity of sod-podzolic light loamy soil, weather conditions, a mineral nutrition level. Results of researches have shown that acidity of sod-podzolic light loamy soil has influence on fibre flax yield productivity and its quality. However, at exact performance of all technology elements, correct system macro-and microfertilizer productivity of flax stock at pH 6,3-6,5 was enough high, the output of a fibre changed on the average for two years from 30,5 up to 33,5 c/ha, percent of long fibre come to 56,1-64,2. The output of fibre flax is the most important index of flax yield. During the first year of investigations 29,3-30,2 c/ha of flax fibre was received in control variants. In variant N15P55K80 at 4,8-4,9 ph the fibre flax output has made 29,5 c/ha, at 5,3-5,6 - 31,7c/ha, at 6,3-6,5 - 31,1 c/ha. The higher dosage of nitrogen is conditioned increase from О, 3 up to 2,6 c/ha. Folia application of flax sowings by trace elements was more effective at higher nitrogen dosage. So, fibre flax output was higher in variant N15P55K90+B90+Zn180 on 0,4-2,8 c/ha, and on 1,9-6,5 c/ha in variant N25P90K130+B90+Zn180. It being known that minimum increase was observed at рh 6,3-6,5
