Effects of potassium deficiency on nitrogen metabolism of fruit plants Soluble N accumulated in the leaves of K-deficient apple trees grown in sand culture and in the leaves of apples, pears, prunes and vines in the field. Put... CG Forshey,MW Mckee - 《Amer Soc Hort Sci J》 被引量: ...
Similar total recovery of the labeled fertilizer N was found in the trees and soil in both treatments (N1−61.7% N3−56%). However, the distribution between tree and soil was different. The amount of recovered residual fertilizer in the soil was much larger in the N3 treatment than in ...

is lacking and this information is needed for implementation of best management practices (BMPs). A field experiment was conducted from 1997 to 2000 on a Riviera fine sand (loamy, siliceous, hyperthermic, Arenic Glossaqualf) with 30-yr-old+ white Marsh grapefruit trees on sour orange (...
Nitrogen was applied as Ndepleted (NH4)2SO4 to mature almond [Prunus dulcis (Mill.) D.A. Webb, cv. Nonpareil] trees in a comercial orchard. The kinetics of isotopic N accumulation by developing fruit and leaves permitted some discrimination between the 2 principal N pools: the N previously...
Springtime 15Nitrogen Uptake, Partitioning, and Leaching Losses from Young Bearing Citrus Trees of Differing Nitrogen Status Nitrogen uptake, allocation, and leaching losses from soil were quantified during spring, for 4-year-old bearing `Redblush' grapefruit (Citrus 脳 paradisi ... John,D.,Lea-...

Based on these results, annual fertigation of 25 year old `French'' prune trees with 0.11 to 0.23 kg N per tree is a sufficient amount of N to provide for good fruit yields, tree growth and orchard health, and minimize N leaching into groundwater....
