This publication compares the Haney and Cornell soil health tests on three long-term trials. It discusses the findings and recommendations for managing for soil health and crop yield.
By routinely measuring the electrical conductivity (EC) and pH of growing media and irrigation water for container-grown nursery crops, growers can monitor nutrient availability and scout for problems. Learn how to use the pour-through extraction procedures as part of your nursery's quality control program.
Plants differ in their tolerance to soil pH. This publication provides information on determining the target pH for different crops and calculating the appropriate amount of materials to reduce soil pH when necessary.
This publication provides updated recommendations for phosphorus fertilizer application in corn, soybean, and small grains crops. It includes background and historical information about phosphorus critical levels, phosphorus rate recommendations, phosphorus accumulation in soils, and changes in recommendations.
This publication discusses the results of a study that evaluated the soil fertility status of row crops across four regions of North Carolina. The study assessed factors affecting soil fertility, such as acidity, organic matter, and cation exchange capacity to provide a more accurate snapshot of soil fertility.
