Nutrition in Wheat - In Crop
Constraint – Calcium
Calcium is a macronutrient involved in the proper functioning of growing points and maintaining strong cell walls
Deficiency symptoms are rare because calcium is common in soil, and is a component of many fertiliser and soil amendment products
Seen first in youngest tissues
Plants may be limp/wilt, with stunted root systems
Soils low in calcium usually have associated adverse conditions, such as low pH and aluminium, iron, and manganese toxicities
These associated conditions can cause varying yield penalties
A soil test to determine how deficient the soil is, and the application of an appropriate amount of lime, is usually sufficient to correct the deficiency.
