Seasonal trends in the elemental content of sweet cherry leaves
Seasonal variation of N, P, K, Ca, Mg, S, Fe, Mn, Cu, Zn, B were determined in leaves of Prunus avium L., cv Napoleon. An equation for each element relating sampling date and content is given. Nitrogen, P, K, and Zn concentrations decreased during the vegetative cycle, while Ca, Mg, Fe and B increased. There was no seasonal change for S and Cu. The most suitable sampling period for a nutritional diagnosis is from mid-July to mid-August. There are significant interevolutive correlations among all the pairs of elements except those in which S and/or Cu take part. Certain soil parameters, such as an alkaline pH, a coarse texture and low content of k and organic matter could be responsible for the nutritive observed.
