Spring growth of almond nursery trees depends upon nitrogen from both plant reserves and spring fertilizer application

Effects of copper, zinc and urea on defoliation and nitrogen reserves in nursery plants of almond

“…Initial growth of almond nursery trees in the Spring, after transplanting, is dependent on N reserves in the trees and N in the soil (Bi et al, 2003). Work with other deciduous trees has also shown that the application of urea sprays in the Autumn can increase tree N reserves Dong et al, 2002).…”

Soil and foliar nitrogen supply affects the composition of nitrogen and carbohydrates in young almond trees

“…This internal cycling provides the structural components and energy needed for early new growth (Taylor and May, 1967;Titus and Kang, 1982;Tromp, 1983;Oliveira and Priestley, 1988;Millard and Thomson, 1989;Loescher et al, 1990;Millard, 1995Millard, , 1996Neilsen et al, 2001;Cheng and Fuchigami, 2002;Bi et al, 2003).…”

Rate of nitrogen application during the growing season alters the response of container-grown rhododendron and azalea to foliar application of urea in the Autumn

“…With bareroot nursery trees, N application to soil usually has a high risk of losses due to leaching, while foliar N application can have a higher recovery rate Rosecrance et al, 1998;Shim et al, 1972;Tagliavini et al, 1998). Foliar fertilisation in the Autumn is a common strategy used with fruit tree nursery stock to decrease the potential for N-leaching and problems with hardiness sometimes associated with high soil N in the Autumn, and to improve plant performance the following Spring (Bi et al, 2003;Dong et al, 2005;Rikala et al, 2004).…”
