Absorçao de zinco por folhas inteiras de cafeeiro (Coffea arabica L.), 2: Efeito de diferentes compostos de zinco e do pH da soluçao externa - Ene-Mar 1972

++Dat. num. 20 ref. Sum. (En, Pt)

Using a technique worked out for experiments on ion absorption by intact leaves, the authors studied the effects of different sources of zinc (sulphate, cloride, acetate, nitrate and chelate). The effects of zinc suphate solution at different pH was also tested. The conclusions are: zinc sulphate is the best source for foliar application; the absorption of zinc is more actif when the solution of zinc sulphate is pH 6,0
