Nutrients

Onions - Deformation

Symptoms
B deficient plants become deep green and brittle. They can be stunted or distorted.

Reasons
Boron Deficiency B Deficiency is most common on low pH and sandy soils as it is readily leached. It is important to maintain the correct balance of calcium, nitrogen and boron in the soil. High calcium and high nitrogen levels can reduce boron uptake.

Boron Deficiency made worse by

Sandy soils
Alkaline soils
Soils low in organic matter
High levels of nitrogen
High levels of calcium
Cold wet weather
Periods of drought

Boron is important for

Carbohydrate metabolism and protein synthesis
Calcium movement within the plant
Improved yield and storage quality
High requirement
