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.
Nearly all North Carolina soils are naturally acidic and need lime, which neutralizes the acidity, for optimum growth of crops, forages, turf, trees, and many ornamentals. Nature and cause of acidity, benefits of proper lime usage, soil testing and target pH, liming materials and lime application and incorporation are presented in this publication.
This publication offers fertilizer suggestions for a variety of crops, including field, pasture and hay crops, tree fruit, small fruit, ornamental plants and vegetable crops.
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 provides information to growers about soybean production in North Carolina. It discusses economic trends and forecasts, cultural practices, variety selection, planting decisions, nutrient management, diseases and pests, and other production practices.
2020 Cotton Information is meant to help growers plan for the coming year and make management decisions based on the unique opportunities and challenges the year might bring.
This publication, chapter 6 of the North Carolina Soybean Production Guide, covers fertilization and nutrient management in soybean production.
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 offers a discussion on how to lime Fraser fir Christmas trees. Fraser fir Christmas trees require a lower soil pH than most crops grown in North Carolina. Special management strategies for soil pH, calcium, and magnesium are needed to provide proper nutrition without over-liming.
Adequate sulfur is necessary for crops, but there’s no one-size-fits-all recommendation for application in North Carolina. Best management practices take sulfur removal and incidental sulfur inputs for the entire crop rotation, soil type and profile depth layers and soil and plant analysis results.
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
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 publication discusses appropriate fertilizer application for forages in North Carolina.
Phosphorus management is an important aspect of the USDA-NCRS nutrient management standard. Anyone applying animal waste or fertilizer in a nutrient-impaired subwatershed must determine potential phosphorus loss from each field. This publication describes the P-Index or Phosphorus Loss Assessment Tool that is used in North Carolina for this purpose.
Esta publicación explica cómo obtener muestras de suelo representativas y cómo enviarlas para que las analicen. Se incluye también dónde y cuándo tomar muestras, técnicas de muestreo adecuadas y el envío de las muestras para su análisis.
This publication, chapter 7 of the 2020 Cotton Information handbook, provides information about fertilization for cotton crops.
Phosphorus management is an important aspect of the USDA-NCRS nutrient management standard. Anyone applying animal waste or fertilizer in a nutrient-impaired subwatershed must determine potential phosphorus loss from each field. This publication describes in great detail the P-Index or Phosphorus Loss Assessment Tool that is used in North Carolina for this purpose.
