What weather conditions can lead to manganese (Mn) deficiency in crops?

Manganese (Mn) deficiency in crops is often exacerbated by cold and wet weather conditions. In these environments, manganese becomes less available to plants due to the increased moisture content in the soil that can lead to waterlogged conditions. When soils are overly saturated, the manganese may be present but is in forms that plants cannot uptake effectively, which can lead to deficiency symptoms.

Furthermore, cold temperatures can limit plant metabolism and root function, reducing the uptake of essential nutrients, including manganese. This scenario creates a situation where the availability of manganese is diminished, contributing to deficiency in crops. It's important to recognize that nutrient availability is influenced by various environmental factors, and cold, wet conditions particularly hinder the uptake of manganese compared to other weather scenarios.
