Boron deficiency - Strawberry | Yara Ireland

Change crop

Nutrients

Strawberry - Deformation

Symptoms
Damage on floral organs and flower abortion. Poor fruit set leads to fruit malformation or bumpiness. Severe deficiency ultimately produces smaller, softer fruit and a lower yield.

Reasons
Boron deficiency B undersupply commonly results from restricted availibility due to high pH or B leaching from sandy soils.

Strawberry - Discolouration

Symptoms
Interveinal chlorosis starting from leaf margins. Bronzing, especially of leaf veins, may occur on the extreme edges.

Reasons
Boron deficiency B undersupply commonly results from restricted availibility due to high pH or B leaching from sandy soils.

Strawberry - Browning

Symptoms
Interveinal chlorosis starting from leaf margins. Bronzing, especially of leaf veins, may occur on the extreme edges of medium aged leaves. Youngest leaves may show dark, necrotic tips or margins on otherwise dark green tissue. Damage on floral organs and flower abortion. Poor fruit set leads to fruit malformation or bumpiness. Severe deficiency ultimately produces smaller, softer fruit and a lower yield. Root growth can be reduced with stunted, stubby and brown lateral roots.

Symptoms
Poor growth with premature flowering. Leaf size is severely stunted.

Reasons
Boron deficiency (right) B undersupply commonly results from restricted availibility due to high pH or B leaching from sandy soils.
