Corn plant health and crop nutrition

A balanced crop nutrition is essential to maximize corn plant growth.

Nitrogen

Nitrogen is essential for corn plant growth, being one of the main building blocks of proteins. Therefore if the initial plant growth slows, if they are slow to come to flower and have thin stalks, there might be an indication of a nitrogen deficiency.

Potassium

Young corn plants are also most likely deficient in potassium if they are slow to develop. Potassium deficiency increases the susceptibility to stalk rot leading to shorter crops.

Boron and Manganese

When corn plant growth is severely stunted – leaves are thinner than normal, wrinkled and weak, it indicates a boron or manganese deficiency.

Copper

In case of a copper deficiency the tips of the new unfolding leaves are also dried-out and the stalk is often soft and limp.
