Popis: Summerland McIntosh apple trees (Malus domestica Borkh.)on M.9 rootstock were fertigated for the first 3 yr after planting with all combinations of two rates of N (23.5 and 47.0 g tree−1) and three rates of P (0, 17.5 and 35 g tree−1). During this period, soil pH (0.01 M CaCl2) beneath and near the drip emitters declined from 5.8 to
