Nitrogen deficiency-Almond

Symptoms
Reduced branching and shoot growth are symptoms of N deficiency. Leaves remain small, narrow and pale green. Chlorosis starts from the marginal area and proceeds towards the leaf base. Leaf tissues show a bright, light brown to bronze tint with small brown spots, coalescing to bigger necrotic lesions. Older leaves are affected first and drop off prematurely. Senescence in autumn starts earlier than normal.

Reasons
Nitrogen deficiency. During the early growth in spring, N demand of the plant is covered by stored N in the woody parts of the tree, but current year‘s uptake is the main N source. The main part of the N supplied to the trees goes into fruit, hulls and kernels. Therefore, the crop load is a good indicator for the tree‘s nitrogen demand. To overview the tree N status during the season, a leaf analysis is a good tool. Leaf N contents in a range of 2.2 to 2.5 % are optimum.
