Influence of soil acidification on chemical composition of tobacco leaves
1994
Wisniowska-Kielian, B. (University of Agriculture, Krakow (Poland). Dept. of Agricultural Chemistry)
Similar yields of tobacco leaves were obtained on soils with various acidification degree and share of exchangeable Al in exchangeable acidity. The fact may testify a low sensitivity of this plant to an increased content of aluminium. Top dressing with nitrogen slightly affected tobacco yield on acid soil, whilst on very acid soil it had no influence on its amount. Ca, K, Mg and total N content in tobacco leaves was similar on both soils; on very acid soil Fe, Cu and P concentrations were much lower, whilst Na, Zn, and particularly Mn and Al levels on this soil were much higher. Fertilization with nitrogen caused a marked decrease in Fe, Na and K content in tobacco leaves from both experiments, in Al and Ca content on acid soil, and Mn and Mg content on very acid soil
