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 factsheet for farmers describes concepts, terminology, and guidelines concerning soil sampling. Proper testing allows farmers to apply the correct amount of lime and fertilizer to fields.
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.
North Carolina has an abundant supply of clean water, a resource vital to our high quality of life. Rivers, lakes, groundwater aquifers, and coastal estuaries are crucial to public health, economic development, and recreational opportunities. However, our water sources are constantly threatened with degradation by such activities as imprudent development, improperly managed agricultural and industrial activities, and unsound waste disposal practices. The soil exerts an important influence on water quality. How we manage the soil and what we put on it determine, in part, the level of treatment required to make our water supplies safe and enjoyable. This fact sheet explains how soils influence water quality and why efficient soil management helps protect water quality.
This chapter from the North Carolina Organic Commodities Production Guide discusses the organic standards for soil management.
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 discusses best practices management to prevent agricultural activities from contaminating groundwater. It covers the role of soil on the quality of groundwater, soil characteristics, characteristics of potential pollutants and management practices such as nitrogen and pesticide management.
