Liming and fertilization effect on yield and phosphorus, potassium, calcium and magnesium content in Virginia tobacco

The influence of fertilization with phosphorus on tobacco yield on the mobile Al content in the soil, and on the potassium, calcium and magnesium content in tobacco leaves was investigated on calcified and non-calcified loess soil with an acid reaction. The experiment comprised six treatments randomized according to the block method with four repetitions. When 3.5 t/ha dolomite was applied, the soil acidity and the mobile aluminium content were reduced. The magnesium and phosphorus content in the tobacco leaf increased considerably, and so did the tobacco yield.
