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.

Winter Annual Cover Crops

By: Carl Crozier, Greg Hoyt, Michael Wagger SoilFacts

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.

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.

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 Sampling for Precision Farming Systems

By: Carl Crozier, Ron Heiniger SoilFacts

This factsheet for farmers describes concepts, terminology, and guidelines concerning precision soil sampling. Proper testing allows farmers to apply the correct amount of lime and fertilizer to fields.

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.

2019 Cotton Information

By: Keith Edmisten, Guy Collins, Carl Crozier, Alan York, David Hardy, Dominic Reisig, Gary Bullen, Lindsey Thiessen, Rachel Atwell Vann, Charlie Cahoon, Bill Foote

2019 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.

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.

Minimizing Risks of Soil Contaminants in Urban Gardens

By: Carl Crozier, Matthew Polizzotto, Lucy Bradley SoilFacts

This publication alerts prospective gardeners to some of the most common contaminants in urban soils, such as lead and other toxic metals, solvents, pesticides and total petroleum hydrocarbons. This will help minimize potential risks to gardeners and to those who consume garden produce. The document includes information regarding site characterization, common contaminants, soil testing, interpretation of results and strategies for reducing exposure risks.

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.

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.


By: Carl Crozier, David Hardy

This publication, chapter 7 of the 2019 Cotton Information handbook, provides information about fertilization for cotton crops.

Alternative Synthetic Nitrogen Fertilizer Products for Row Crop Production

By: Deanna Osmond, Carl Crozier, Ron Heiniger SoilFacts

Nitrogen fertilizer products are being developed and marketed as having the potential to increase yields and nutrient use efficiency, and decrease volatilization (gas). How do these products actually perform on different soils and row crops, under various climatic conditions? This publication summarizes findings from recent studies that investigated alternative nitrogen fertilizer products for row crops in four North Carolina regions.

Managing Equipment Traffic to Limit Soil Compaction

By: Carl Crozier, Joshua L. Heitman SoilFacts

Most soil compaction from equipment traffic occurs where tires contact soil during the first pass over soil. Farmers can reduce compaction by limiting traffic to interrows that have already been trafficked. The authors report their research on traffic patterns and recommend ways that farmers can manage field traffic to limit soil compaction.

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

Phosphorus Deficiency of Carinata

By: Angela Post, Paul Cockson, Carl Crozier, Ramon Leon, Brian Whipker, Michael Mulvaney From the Field - Agronomy Notes

In this Brassica carinata (Ethiopian mustard) update, we highlight the symptoms of nitrogen deficiency. These images are part of a project by the Southeast Partnership for Advanced Renewables from Carinata (SPARC) to develop a diagnostic series for the identification of nutrient disorders of Carinata. Carinata is an exciting new crop used for a wide variety of primary and secondary agricultural products including cover crops, feed stock, high protein meal, and rocket jet fuel. It is similar in management to Canola given both Canola and Carinata are winter annual Brassica oilseed crops.
