Sulphur Deficiency

Occasionally nitrogen deficiency may be confused with sulphur deficiency. Sulphur deficiency symptoms will be very similar to nitrogen deficiency symptoms in appearance except they occur on the plant. Sulphur is a somewhat immobile nutrient in the plant and thus the deficiency symptoms develop in the young leaves and organs first, generally in or near the top of the plant. Remember, nitrogen deficiency shows up on older tissue first, then moves up the plant. Sulphur deficiency is similar in appearance but shows up on the younger tissue first. Sulphur deficiency should be suspected when nitrogen deficiency symptoms develop in or near the top of plants growing in low organic matter soils or in areas recently land-formed. Soil testing and sound soil fertility is the proper sulfur management routine.

STARKVILLE, Miss. -- When the calendar turns to September, many who call Mississippi home long for cooler temperatures to relieve the summer’s heat, but the state’s cotton growers want high temperatures and dry weather to drag into October.

STARKVILLE, Miss. -- MSU Extension agents will be assessing agricultural damage from early-June flooding until well into July, but preliminary estimates indicate losses could break records.

The 2019 Yazoo Backwater Area flood caused $617 million in crop damage alone. It looks like the more recent flood will exceed those losses.

Heavy rainfall, primarily north of U.S. Highway 82, throughout the second week of June waterlogged crops during critical growth stages. Flooding caused complete or partial losses in many fields.

Because it is the first crop planted starting in March, Mississippi corn is in much better shape than other row crops struggling with the challenges of wet, cool weather.

STARKVILLE, Miss. -- Mississippi row crop growers are planning to plant more soybeans and corn in 2021 than they did last year but not as much cotton, rice or hay.

The National Agricultural Statistics Service, a branch of the U.S. Department of Agriculture, publishes its planting intentions report each year at the end of March. This report provides a state-by-state estimation of how many acres of corn, soybeans, wheat and cotton farmers will plant in the upcoming growing season.

STARKVILLE, Miss. -- Each February marks the occasion for producers to share their research and programming needs with Mississippi State University agricultural specialists in person.

To comply with COVID-19 social distancing guidelines, the opportunity will be extended virtually this year.
