“…Similar findings have been reported for K and Mg in shaded coffee systems, but with higher N concentrations (Ricci et al, 2006). The obtained values for leaf macro-and micronutrients can be considered close to adequate in C. arabica and C. canephora (Bragança et al, 2007(Bragança et al, , 2008Ramalho et al, 2013;Martins et al, 2014), although the Figure 3. Daily mean relative humidity values in 'Conilon' coffee (Coffea canephora) intercropped with rubber trees (Hevea brasiliensis) in summer on the northern (A) and southern (B) sides of the coffee tree rows and in winter on the northern (C) and southern (D) sides.…”

“…This contrasted with the impact of extreme temperatures in mineral contents at leaf level (Ramalho et al, 2013;Martins et al, 2014), and might be linked to the strong sink effect of the fruits that could withdraw minerals from other plant organs, together with the mineral availability provided by the applied fertilization in the present experiments.…”

“…Such preservation of adequate mineral contents and balance within the plant is determinant for the expression of stress tolerance mechanisms on coffee (Ramalho et al, 2013), and assume a particular importance under predicted future conditions of climate changes and global warming (Martins et al, 2014), which are expected to simultaneously alter temperature and water availability to main crops, including to coffee (Rodrigues et al, 2016).…”

“…O aumento da biomassa e a redução da severidade da ferrugem, promovidas pelo aumento da concentração de CO 2 atmosférico, podem compensar efeitos negativos de outras variáveis do ambiente, que serão alteradas com as mudanças climáticas. Martins et al (2014) avaliaram o efeito combinado do aumento da concentração de CO 2 e da temperatura e verificaram que, apesar das mudanças promovidas pelos dois fatores do ambiente, a maioria dos nutrientes foi mantida dentro de uma faixa considerada adequada, o que indica que a planta pode manter balanços minerais satisfatórios nos cenários climáticos futuros. Entretanto, em experimento do tipo Face, verificou-se que, em cafeeiros cultivados em atmosfera enriquecida com CO 2 , o teor de P disponível no solo é o que mais se reduz, e isto é indicativo da necessidade de reposição adequada deste nutriente (Maluf et al, 2015).…”
