The fumigant 1,3-dichloropropene (1,3-D) has been identified as a partial replacement for methyl bromide (CH3Br) in soil fumigation. 1,3-Dichloropropene is formulated for soil fumigation as Telone II (Dow AgroSciences, Indianapolis, IN) for shank application and as an emulsifiable concentrate (EC) (Telone EC or InLine; Dow AgroSciences) for drip application. This study investigated the effect o...

in this work x-ray fluorescence (xrf) technique was used to evaluate the soil pollution withheavy metals for twenty four surface soil samples (0–10 cm in depth) from various locations to cover theindustrial area in omdurman city, sudan. concentrations of 10 elements cr, ni, cu, zn, zr, pb, rb, co, cd andas were determined. it was found that cr, cu and cd concentrations for almost all studied si...

Rainfall is a driving force for the transport of environmental contaminants from agricultural soils to surficial water bodies via surface runoff. The objective of this study was to characterize the effects of antecedent soil moisture content on the fate and transport of surface applied commercial urea, a common form of nitrogen (N) fertilizer, following a rainfall event that occurs within 24 hr...

Agricultural targets mainly concern towards the preservation of the soil and crop productivity. Recent study and analysis of radars in the field of agriculture has determined that interaction of the radar pulses with various conditions of soil have significantly affected backscattering. On discussion to soil conditions, may account such as the moisture content availed and soil tillage. Tilling ...

Grazing lands in the southeastern United States of America are managed primarily for introduced plant species that have high forage production potential or that fit in a niche within a farming system. Forages are typically managed with fertilization and grazing pressure on a seasonal basis, depending upon growth habit. Nitrogen (N) application is one of the key determinants of pasture productiv...

Vertebrate fossils and continental sediments provide a rich record of variations in the isotopic composition of surface environments. To interpret these records, a greater understanding of isotopic sources, as well as fractionations associated with animal physiology, soil geochemistry, and diagenesis, has been essential. Tooth enamel and fish otoliths yield subannual records of surface environm...

Agricultural systems often require added phosphorus to achieve optimum crop and livestock production. The application of soil amendments, such as inorganic fertilizers, manure, biosolids, and waste water, can improve soil fertility and help produce optimum crop yields. However, many of these amendments, particularly organic materials such as animal manure, are often applied in excess of crop nu...

A modification of the GLEAMS model was used to determine application windows which would optimise efficacy and environmental safety for herbicide application to a forest site. Herbicide/soil partition coefticients were determined using soil samples collected from the study site for two herbicides (imazapyr, K,=46, triclopyr ester, K,,=l038)andpublishedvaluesfortwootherherbicides(henarinone,K,=5...
