| Abstract:
NaNO3 treatments, induced an important accumulation of Na (r=0.986) caused by the presence of Na ion in the salt and a small increase of N (r=0.953) and decrease of Ca (r=-0.904). The other nutrients considered were not altered. (NH4)2SO4 treatments caused a very large accumulation of N (r=0.974), P (r=0.967) and Fe (r=0.985) and at the same time an important decrease of K (r=-0.959). | |
