Interaction of methyl bromide with soil.
نویسندگان
چکیده
Because methyl bromide (CH3Br) is a widely used agricultural fumigant for soil disinfection, it is important to know the chemical behavior and fate of CH3Br as a result of its use for soil treatment. A solid-state 13C NMR study of 13CH3Br-treated soil and soil-component samples shows that methylation of soil organic matter may be the major pathway for degradation of CH3Br in soils. Adsorption of CH3Br on a dried clay like Ca-montmorillonite or kaolinite does not contribute directly to the degradation of CH3Br. The results are interpreted in terms of the chemical structures of separated soil fractions and the nature of the separation procedure.

This study investigated the effects of soil amendment with olive mill by-products (Jift) on growthof chickpea and their symbiosis with Vesicular arbascular (VA) fungi. A split plot design with threereplications was used, in which soil treatments (methyl bromide fumigated, fungicide, and untreatedcontrol) were assigned to main plots and soil-Jift mixtures(Jift: Soil; 0:10, 1:9, 2:8, 3:7, and 4:6...
متن کاملEnhanced degradation of the volatile fumigant-nematicides 1,3-d and methyl bromide in soil.
The use of the gaseous funaigant-nematicide methyl bromide in agriculture is scheduled to be phased out in the year 2001.1,3-Dichloropropene (1,3-D) in combination with chloropicrin and an herbicide is considered to be a viable alternative to methyl bromide for some crops. 1,3-Dichloropropene consists of two isomers, cis- and trans-l,3-D. A number of soil bacteria have been shown to initially d...

Field experiments were conducted to evaluate growth promotion and induced systemic disease resistance (ISR) in cucumber mediated by plant growth-promoting rhizobacteria (PGPR) with and without methyl bromide soil fumigation. In both fumigated and nonfumigated plots, numbers of cucumber beetles, Acalymma vittata (F.), and the incidence of bacterial wilt disease, caused by the beetle-transmitted ...

Soil fumigation is used to eliminate plant pathogens and weeds in commercial practice and to eliminate organisms in controlled experiments, e.g., vesicular arbuscular mycorrhizal fungi (VAMF). This study was conducted to study the effect of methyl bromide fumigation on plant accumulation of 14 elements and assess plant colonization by VAMF after fumigation. Field experiments were conducted near...

Field experiments were carried out at JUST agricultural research center during 1999-2000 growing season to evaluate the effects of soil amendment with olive mill by-products (Jift) on growth of faba bean and their symbiosis with VA fungi. Soil was amended with Jift at different levels (Jift: Soil; 0:10, 1:9, 2:8, 3:7 and 4:6) and exposed to solarization, methyl bromide and fungicide treatments....
