Bermudagrass [Cynodon dactylon (L.) Pers.] is widely grown throughout the southeastern United States and many other countries for forage. Tifton 85, a hybrid between C. dactylon and C. nlemfuensis, is currently the recommended cultivar for grazing an

A cotton (Gossypium hirsutum)–peanut (Arachis hypogaea L.) rotation is widely practiced in the southern coastal plain following the reemergence of cotton as a major crop in the 1990s. Very few plant nutrition studies have been conducted in the coas

Most soils in the southern Coastal Plain need liming; however, long-term data are needed on its value and changes in soil profile pH, Ca, or Mg. Field studies with lime rates have been maintained on a Tifton soil (Plinthic Kandiudult) for 31 yr and o

Soil pH measurements in salt solutions are often used to provide values which are reportedly independent of suspension effect errors. Field plots where soil pH levels, measured in water, had been maintained at about 5.7, 6.2, 6.5, and 7.0 for 15 year

The effect of long-term fertilizer applications on soil test levels, yield, and crop removal depends on soil texture and mineralogy. The objectives of this study were to measure the fluctuations in soil P and K in soils of varying texture and to eval

Many soil extractants have been developed for determination of zinc (Zn) availability to plants. The optimum soil Zn extractant should be useful not only for prediction of plant Zn concentration but also for detection of applied Zn levels. The object

High soil zinc (Zn) concentrations can cause Zn toxicity in peanuts (Arachis hypogaea L.), which decreases productivity and can be fatal to the plants. The objectives of this study were 1) to determine the optimal sampling time and plant part for dia

Four methods of placement of DBCP (l,2-dibromo-3-chloropropane) and a single method of application of ethoprop (0-ethyl S,S-dipropyl phosphorodithioate) wexe compared in each of two areas for control of nematodes on soybeans. One area was a Marlboro

Application of 1,2-dibromo-3-chloropropane (DBCP) and subsoiling under the row in Tifton sandy loam heavily infested with Meloidogyne incognita increased yields of four soybean cultivars. These cultivars have levels of resistance to M. incognita as f

Yields of 'McNair 800' soybeans, Glycine max (L.) Merr., were significantly increased with ethylene dibromide + chloropicrin, DBCP, phenamiphos, and aldicarb applied at-planting and with phenamiphos, aldicarb, and DBCP applied postplant to soil infes
