Acid soils often need liming to aid crop growth and development. Fall applications provide more time for the lime to react with the soil, less stress on the human component, and better field conditions for equipment operation.
Soil acidity problems rarely have dramatic visual symptoms. Affected areas are less hardy or vigorous in growth; the size of . . . → Read More: Lime Need and Value
With harvest beginning, it is time to think about the next crop. Fall liming allows time for the soil to react before the next summer crop is planted, and takes advantage of the (usually) drier conditions for field operations.
Soil pH measures soil acidity, the master variable of soil fertility. Technically pH is the concentration of hydrogen . . . → Read More: Fall 2014 Lime Programs

The evolution of cotton cultivars has led to higher yield potentials and shorter growing seasons compared to the historical full season cultivars favored in the Mid-South. These newer, faster fruiting cultivars may require more nutrients than older outdated cultivars. Recently, across the Mid-South, many consultants, state extension and research specialists have observed numerous cases of potash . . . → Read More: Late Season Potash Deficiency in Cotton

Described below are the most common nutrient related issues that occur in Mississippi rice production and a few distinctive characteristics to key on when trying to properly identify each issue in the field. Nutrient issues in rice can take on many appearances, but coupled with field histories some of the keys below will aid in identification. . . . → Read More: Keys to Diagnosing Common Nutrient Deficiencies in Rice
Typical symptomology of rice leaf blast
Last week’s weather pattern in the Delta provided near perfect conditions for rice blast (Pyricularia grisea) to occur. Rice blast is generally categorized by the plant part infected (e.g., leaf, neck, panicle). Blast favors mild humid weather, frequent rainfall, and extended periods of leaf wetness. On susceptible cultivars, yield loss . . . → Read More: Rice Leaf Blast Confirmed in Mississippi
Corn reproductive stages generally comprise about 60 days for corn hybrids grown in Mississippi at normal planting dates. Identification of these stages is critical for making prudent management decisions and anticipating crop response to practices and environmental conditions. . . . → Read More: Identifying Corn Reproductive Growth Stages and Management Implications
Diagnosing nutrient deficiencies is not rocket science, but can be cumbersome. Many nutrient related issues occur early in season and can sometimes mimic herbicide injury in appearance. In many instances it is difficult to tell the two apart. Most often nutrition related issues can be confirmed with a properly taken tissue test and corrected with an . . . → Read More: Diagnosing Nutrient Deficiencies in Mississippi Soybeans
More and more corn growers are applying various management inputs around tassel stage in order to improve efficiency and corn productivity. This article discusses how crop physiology affects the appropriate timing and crop response. . . . → Read More: The Tassel Shot: When is the Best Time?
