Almond - Chlorosis

Symptoms
Young leaves can show diffuse chlorotic mottling. Necrotic margins roll up longitudinally and give the plant a wilted, droopy habit. Older leaves are less severely affected, they show only slight marginal necrosis and yellow dots spreading over the leaf blade (can be seen from backside). Ongoing severe deficiency causes stunted growth and premature leaf drop. New, young shoot tips may exhibit bushy, dense leaf growth after dieback of terminal bud.

Reasons
Calcium deficiency. A level of 2% Ca in leaf tissue is adequate.

Calcium deficiency made worse by

  • Acidic soils
  • Sandy or light soils (leaching)
  • Acid peat soils
  • Soils rich in sodium
  • Soils rich in aluminium
  • Drought conditions
  • Fruit high in nitrogen or potassium
  • Large fruit

Calcium is important for

  • Structure, stability and permeability of cell membranes
  • Regulation of enzyme systems
  • Alongside potassium responsible for regulation of stomata
  • Gives plants more resistance to biotic and abiotic stress
  • Proper development of leaves and fruit
  • Prevention of post harvest decay

Yara recommended fertilizers for Calcium

YaraLiva® CAN-17™

YaraLiva® CAN-17™

Almond: Young trees (1-3 years) benefit from nitrate applications as YaraLiva CAN-17 because nitrate nitrogen is readily available as well as soluble calcium for cell wall and membrane formation and soil health. Apply 15-60 lb N/Acre depending on tree age and vigor, at least 1/3 of which should be applied as YaraLiva CAN-17 in the early application. Mature trees need 70 lbs of N/Acre for each 1,000 lbs of nut yield goal. Applications should be split throughout the growing season and adjusted to reflect changes in yield goal. Early applications of YaraLiva CAN-17 help assure N absorption in cool weather and good nut set. Consult your agronomist for further details.
