This publication provides basic information on the nutrient needs of trees and shrubs, types of fertilizers to apply and recommended methods and times of application.
This publication discusses appropriate fertilizer application for forages in North Carolina.
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.
Phosphorus (P) is the second most important nutrient in crop production but is often found in relatively low amounts in native soils. Decades of fertilizer application have led to P enrichment of most North Carolina agricultural soils. Excess soil P that leaves agricultural fields via runoff and drainage can cause algal blooms in water resources that lead to impaired drinking water quality and can limit recreational activities. Maintaining adequate soil P levels for crop growth can reduce P runoff, save money, and protect the environment
Boron (B) is a critical micronutrient essential for the growth, development, and productivity of vegetable crops. Although required in trace amounts, boron plays a fundamental role in plant physiology, influencing cell wall integrity, reproductive success, and metabolic processes. In North Carolina, where diverse soil types and vegetable cropping systems coexist, managing boron availability is vital to optimize yields and ensure crop quality. This publication provides a comprehensive overview of boron’s role in plant health, its behavior in soils, and strategies for effective management.
This publication provides recommendations for managing essential nutrient concentrations when growing organic tobacco in the field.
