The response of coffee (Coffea arabica) seedlings to applied Zn on acid soils that had been limed to give a range of pH values was investigated in the greenhouse. Zinc sulfate was mixed with soils at the rate of 0, 5, 10 and 20 µg/g of Zn. The Zn content of the plants increased with Zn application and decreased with increasing pH. The solubility of Zn in the soils decreased markedly with increasing pH from four to seven. The order of extractability was 0.1N HCl > 0.05N HCl + 0.025N H2SO4 > NH4OAc 1N pH 4.8 > DTPA > EDTA > water soluble. The 0.1N HCl and double acid extractants gave higher correlation with Zn uptake under pH 6.2 than acid solutions.Foi avaliado em casa de vegetação a resposta de mudas de café (Coffea arabica) à aplicação de...
