The Importance of Manganese in Vegetable Crop Nutrition in North Carolina

By: Emmanuel Torres Quezada Vegetable Nutrient Management

Manganese (Mn) is a critical micronutrient essential for the growth, development, and productivity of vegetable crops. Despite being required in trace amounts, manganese plays a pivotal role in key physiological processes, including photosynthesis, enzyme activation, and plant stress mitigation. Its availability in soils is influenced by several factors, particularly soil pH, redox conditions, and organic matter content, making proper management vital for optimal crop performance. This publication provides a comprehensive overview of manganese’s role in plant physiology, its forms and availability in soils, and practical strategies for managing manganese in vegetable production systems.
