Soil Acidity and Liming: Basic Information for Farmers and Gardeners

By: Carl Crozier, David Hardy SoilFacts

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.

Careful Soil Sampling—The Key to Reliable Soil Test Information

By: Carl Crozier, Deanna Osmond, David Hardy SoilFacts

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.

Soil Acidity and Liming for Agricultural Soils

By: Carl Crozier, David Hardy SoilFacts

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.

Effects of Wind-Induced Sodium Salts on Soils in Coastal Agricultural Fields

By: David Hardy, Carl Crozier, Deanna Osmond, Diana Rashash SoilFacts

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.

Soil pH Management for Fraser Fir Christmas Tree Production

By: Carl Crozier, David Hardy SoilFacts

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.

North Carolina Soybean Production Guide

By: Katherine Drake Stowe, Carl Crozier, Gary Bullen, Jim Dunphy, Wesley Everman, David Hardy, Deanna Osmond, Nick Piggott, Sandeep Rana, Dominic Reisig, Gary Roberson, Brandon Schrage, Lindsey Thiessen, Derek Washburn

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.

The North Carolina Phosphorus Loss Assessment Tool (PLAT)

By: Deanna Osmond, David Crouse, David Hardy, Josh Spencer, John Classen SoilFacts

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.

Starter Phosphorus Fertilizer and Additives in North Carolina Soils: Use, Placement, and Plant Response

By: Sheri Cahill, Deanna Osmond, Ronald Gehl, David Hardy, Carl Crozier SoilFacts

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

2018 Cotton Information

By: Keith Edmisten, Guy Collins, Carl Crozier, Alan Meijer, Alan York, David Hardy, Dominic Reisig, Gary Bullen, Lindsey Thiessen, Rachel Atwell

2018 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.

Fertilization and Nutrient Management

By: Carl Crozier, David Hardy

This publication, chapter 6 of the North Carolina Soybean Production Guide, covers fertilization and nutrient management in soybean production.

Sulfur Fertilization of North Carolina Crops

By: Carl Crozier, Greg Hoyt, David Hardy SoilFacts

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.

The North Carolina Phosphorus Loss Assessment Tool (PLAT): A Guide for Technical Specialists

By: Deanna Osmond, David Crouse, David Hardy, Josh Spencer SoilFacts

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.

Deep Soil Sampling for Nutrient Management

By: Deanna Osmond, David Hardy, David Crouse SoilFacts

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.

Fertilization

By: Carl Crozier, David Hardy

This publication, chapter 7 of the 2018 Cotton Information handbook, provides information about fertilization for cotton crops.
