Evolución estacional de nutrimentos en guindo dulce (Prunus avium L.)

The variability of foliar N, P, K, Ca, Mg, Mn, Fe, Zn, and B content as a function of time was studied in an irrigated, 18 year old cherry orchard (Prunus avium L.). Samples were taken during two seasons at 1.5 clays intervals from leaves of 1, 2 to 3 and 4 to 5 years old woody branches. In general, N, P, Cu and Zn concentrations decreased as the growth period advances, while Ca, Mg, Fe and Mn concentration showed an inverse response. The behavior of K and B was very similar, having their higher concentration at the middle of the growing season. The period of higher stability of the macro and micronutrients occurs during the summer. There is an important effect on the mineral concentration according to the leave position for all the nutrients, except for N and P. Considering the good fit of the regression equation, correction factors are proposed for samples taken at any time during the growing season.
