The results of studies showed that residues of 2,4-D bound in the soil are available for wheat plants. It was found that most of radioactive residues detected in the soil were accumulated in fulvic acids fraction soluble in the water. Therefore, this part of residues can be available not only for progressive plants, but also for soil and aquatic organisms. The binding of 2,4-D residues with the soil...
The experiment was carried out under laboratory conditions on sterile and nonsterile humus soil treated with ¹⁴C-2,4-dichlorophenol (DCP). The disappearance dynamics of extractable residues, and formation of the bound ones, as well as diffusion of radioactive volatile substances to the air were observed during 112 days. The results showed that disappearance of extractable residues of 2,4-DCP and binding...
The transformations of ¹⁴C-ring-labeled carbofuran and leaching with water in the humus soil were investigated. The experiments were carried out under laboratory conditions using natural profile of arable layer (mini-lysimeters) and in field lysimeter. The tested compound applied on the soil surface was eluted with water in laboratory and sprinkled four-times every 2 weeks in field trial. Carbofuran...
