An introduction to soil acidity and liming for farmers and gardeners to increase crop income and improve lawn and garden performance. Topics covered include soil pH, soil testing, liming standards and application and incorporation of lime into soil.
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
This publication discusses several causes of soil compaction and provides mitigation 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.
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.
