摘要: Abstract Non‐bearing “Hamlin” orange trees on “Swingle citrumelo” rootstock (32 months‐old) grown a Candler fine sand (hyperthermic, coated Typic Quartzipsamments) were harvested to estimate dry mass, nitrogen (N), phosphorus (P), and potassium (K) accumulation partitioning into various parts of the tree. The above parameters evaluated for under low or high fertilization rates, using either water soluble granular (WSG), controlled release formulation (CRF), liquid fertilizer delivered through irrigation water, i.e., fertigation (FRT). Trees irrigated tree sprinklers with wetting area diameter 3.0 m. Total mass per followed order: CRF > FRT = WSG FRT > CRF > WSG respectively. Effects source individual response pattern few exceptions. Dry in relation total decreased trunk > branch > leaves...
