“…For coffee trees, there are reports on the relationship between Ca availability and yield, where increasing exchangeable Ca contents in the soil lead to linear and significant increases in coffee bean production (Malavolta et al, 1979;Chaves et al, 1991). This is mainly associated with the role of Ca in formation of soil fertility, as well as Ca being the third nutrient most required by coffee (Guimarães and Reis, 2010).…”

“…A América Latina apresenta deficiência nutricional de cálcio cada vez mais freqüente, refletindo baixa produtividade agropecuária (MALAVOLTA et al, 1979). Os mesmos autores enfatizam o estudo do papel desse macronutriente, em função da carência que ocorre em muitas regiões, além do que a adubação das pastagens por superfosfato, leva à imobilização do cálcio, pelo ácido formado na degradação desse fertilizante.…”

“…It was caused the highest co n t ent of CEC, BS, P-total, and C-organic found in the inceptisol of 14.94 me/100 g; 28.98%; 0.37%, and 1.70%, respectively. According to Malavolta et al (1979); Chaves, Pavan and Miy a za w a (1991) the increased Ca-exchangeable content had a linear and significant relationship with increased the yield of coffee beans. Bradl (2004) reported that organic matter had a positive correlation with soil cation exchange.…”
