A field study was conducted to determine nitrogen (N) mineralization from broiler litter (EL) in two Coastal Plain soils of differing texture, sandy (Tifton loamy sand) or clayey (Greenville sandy clay loam). These soils represented the broad range in surface textures conmlOnly found in soils used {or agricultural production in the southeastern Coastal Plain. Published protocols used for the st...

Human infections by Toxocara canis or Toxocara cati larvae are frequent and have a cosmopolitan distribution resulting, sometimes, in the occurrence of visceral larva migrans syndrome. Ingestion of embryonated Toxocara eggs, present in the superficial layers of the soil, represents the most important way for human infection by these ascarids. Therefore, contact with contaminated soil is conside...

Five methods for extracting nematodes from soil were compared using three sandy soils and three clay soils. Although no one method was superior to the others for all the genera in any one particular soil, the decanting plus sieving plus Baermann tray method was generally the most efficient for sandy soils and the decanting plus sieving plus centrifugal sugar flotation method the most efficient ...

Since 1985 two series of field trials have been conducted or established to assess the value of lime and phosphogypsum for the amelioration of aluminium toxicity. The first series considered their use on weak, coastal sandy soils and the secondconcerned their use on midlands' acid soils with high clay and organic matter contents and under the minimum tillage system. On weak sandy soils the over...

American chestnut trees once dominated vast areas of deciduous forest in eastern North America, but the exotic chestnut blight almost eliminated the species from the region. Introduction of blight-resistant American chestnut hybrids will probably start in the next decade after many years of tree breeding. What were the historic effects of chestnut on forest soils, and what changes may follow re...

This study was conducted to investigate the effects of soil moisture content on reflectance spectra of sandy soils with different phosphorus (P) concentrations using UV-VIS-NIR reflectance spectroscopy. Sandy soils with average particle size of 250 μm were used. Investigations were conducted at 0, 12.5, 62.5, 175, 375, 750, and 1000 mg/kg phosphorus application rates. Three soil moisture conten...

Salinomycin is polyether ionophore, commonly used in poultry industry for the prevention of coccidial infections and promotion of growth. A large amount of the administered antibiotic is excreted as parent compound, eventually reaching agricultural lands. This makes it imperative for researchers to understand the behavior of the compound in soil environment by conducting sorption-desorption stu...

Aiming to reduce herbicide leaching, "in situ" adsorption of herbicide-micelle formulations to soils was explored. Sulfentrazone or metolachlor were solubilized in cationic micelles, and these herbicide-micelle formulations were applied to sandy and alluvial soils. Sulfentrazone adsorption to the soils was negligible; however, its adsorption via its solubilization in micelles and their adsorpti...
