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.
This factsheet describes the effect of fertilizer nitrogen on water quality and the environment. It provides guidelines for managing soil fertility on farms to preserve water quality.
This publication explains how to obtain representative soil samples and to submit them for analysis. Where and when to take samples, proper sampling techniques, and submitting the samples for analysis are all covered.
This publication discusses the effects of saltwater intrusion on soil fertility, how to identify issues with salt-affected soils, and various options to address these problems.
This chapter from the North Carolina Organic Commodities Production Guide discusses the organic standards for soil management.
This factsheet describes the nutrient composition of poultry manure and land application techniques based on matching the nutritional requirements of the crop with the nutrients available in manure. This publication also includes a worksheet to determine the nutrient needs of your crop.
This publication addresses the two major soil problems found on residential properties and how to rectify them: lack of the three necessary nutrients (phosphorus, nitrogen and potassium) and soil pH.
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.
Fine-ground basalt rock has recently become available as a soil amendment in North Carolina. This publication discusses the agricultural application of fine-ground basalt rock, the results of an incubation study to determine its lime equivalence, and its effects on soil nutrients and fertility.
This publication provides information on the impacts wind-driven events have on the soil fertility. Salt water from storm surges, ocean spray, and tidal surges may increase sodium levels in coastal soils, which can be toxic to plants.
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.
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 phosphorus 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 nitrogen deficiency in soybean production in North Carolina.
This Soybean Nutrient Deficiency Information factsheet describes the symptoms and management of boron 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 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 magnesium 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 molybdenum deficiency in soybean production in North Carolina.
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 Soybean Nutrient Deficiency Information factsheet describes the symptoms and management of potassium 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.
