This Soils and Plant Nutrients Chapter from the Extension Gardener Handbook examines the physical and chemical properties of soil as well as the important role organic matter plays. The chapter discusses how to submit a soil sample for testing and how to read the report to apply necessary fertilizers.
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.
This publication discusses production of winter annual cover crops, their benefits and management. Research has shown several important benefits of planting winter annual cover crops, chief among them erosion control, addition of nitrogen (N) to the soil for use by a subsequent crop, removal of nitrogen from the soil to prevent nutrient loading, buildup of soil organic matter and buildup of residue that acts as a mulch for water conservation or retention.
This publication discusses how excess zinc and copper from animal manure can lead to soil toxicity and harm crops in North Carolina. It covers where zinc and copper come from, potential harmful effects, and ways to prevent toxicity. Management strategies include soil testing, accurate manure application, record-keeping, and adjusting animal feed. Mitigation methods like soil turnover and pH modification are also discussed.
This Soybean Nutrient Deficiency Information factsheet describes the symptoms and management of boron deficiency in soybean production in North Carolina.
Soil samples that determine lime and fertilizer needs of crops routinely come from the top 4 to 8 inches of soil. However, deep soil samples will be needed for the Phosphorus Loss Assessment Tool (PLAT), and this publication describes how to take these 28- to 32-inch deep samples.
This Soybean Nutrient Deficiency Information factsheet describes the symptoms and management of magnesium deficiency in soybean production in North Carolina.
This Soybean Nutrient Deficiency Information factsheet describes the symptoms and management of nitrogen deficiency in soybean production in North Carolina.
This Soybean Nutrient Deficiency Information factsheet describes the symptoms and management of aluminum toxicity in soybean production in North Carolina.
This Soybean Nutrient Deficiency Information factsheet describes the symptoms and management of molybdenum deficiency in soybean production in North Carolina.
This Soybean Nutrient Deficiency Information factsheet describes the symptoms and management of sulfur deficiency in soybean production in North Carolina.
This Soybean Nutrient Deficiency Information factsheet describes the symptoms and management of copper deficiency in soybean production in North Carolina.
This publication discusses the results of recent nitrogen rate trials in the North Carolina coastal plain that assessed the recommendations of the Realistic Yield Expectation (RYE) database.
This Soybean Nutrient Deficiency Information factsheet describes the symptoms and management of potassium deficiency in soybean production in North Carolina.
This publication discusses the Realistic Yield Expectations database as a resource for nitrogen fertilization rate decisionmaking. Topics include recent research and the resulting updates to the database for improved nitrogen fertilizer rates based on new yield data.
This Soybean Nutrient Deficiency Information factsheet describes the symptoms and management of phosphorus deficiency in soybean production in North Carolina.
This Soybean Nutrient Deficiency Information factsheet describes the symptoms and management of manganese deficiency in soybean production in North Carolina.
This Soybean Nutrient Deficiency Information factsheet describes the symptoms and management of zinc deficiency in soybean production in North Carolina.
