Soil Fertility/Nutrient Management
Managing soil fertility and nutrients for crop production involves many factors. Soil test-based recommendations provide information regarding whether supplemental nutrients may, or may not, be useful in growing plants on a particular soil. Fertilizer costs have increased substantially over the past 10 years, and there is more interest in using organic fertilizers. Lime in Mississippi is a significant investment. Furthermore, there is increased manager and societal interest in managing plant nutrients to minimize any negative effects within the agriculture-environment interface.
Mississippi State University has a long and distinguished history of soils, soil fertility, and nutrient management research and extension that is drawn upon for our recommendations. Much of that information for growing most agronomic crops in Mississippi is now collated here.
MSU Extension Service Publication 2647 Nutrient Management Guidelines for Agronomic Crops Grown in Mississippi, contains the following information:
- Introduction to Nutrient Management
- The Soils of Mississippi
- Plant Nutrients
- Introduction to Soil Testing

CLARKSDALE, Miss. -- Growers who planted cover crops for the first time last year will share their experiences with other producers at a cover crop field day.
SAUCIER, Miss. -- Producers and gardeners looking for tips on growing herbs and improving their soil can attend a July 20 field day.
STARKVILLE, Miss. -- Producers who plant winter crops with no intention of harvesting them reap the benefits of soil conservation, weed control and nutrient retention.
On the flip side, however, the practice of almost constant production in a field creates issues with pest management. Farmers who “plant green” have to balance these challenges to best prepare the way for good crops each year.
New manager of operations Keri Jones recently joined the Mississippi State University Extension Service Soil Testing Laboratory, and she's ready to enhance the unit's efficiency."
"My primary goal is to provide accurate soil analysis in a timely manner," said Jones, an Extension associate who has worked in the MSU Department of Plant and Soil Sciences since 2016. "I hope to improve the overall efficiency of the lab as well as update soil nutrient application recommendations."
STARKVILLE, Miss. -- One major cost of producing a good crop is ensuring plants are fertilized well, an operational expense that may consume a significant part of farm budgets.
Bryon Parman, an agricultural economist with the Mississippi State University Extension Service, said nutrient application and replenishment may consume more than 13 and 14 percent of total operating expenses for cotton and soybeans.
“For crops with high nutrient demand such as corn, this nutrient cost may comprise more than 40 percent of variable costs,” Parman said.
