Mechanisms of adsorption of ,-triazines by clay colloids and factors affecting plant availability, In the process of developing and utilizing these chemicals we must come to understand how they affect the target organisms and what becomes of them after they have done their job. The purpose of this review is to discuss. the behavior of one family of these organic compounds, the .-triazines, at th

Adsorption of triazine herbicides on soil organic matter, including a short review on soil organic rawn from the analysis of data by simple correlation analysis and by multiple regression analysis. These techniques also indicated that the cation-exchange capacities and, in some instances, the clay contents of soils could also be inversely correlated with preemergent herbicide phytotoxicity. . and

Volatilization, the latter, is discussed in another part of this volume (... 1970). The two general processes of non-gaseous movement, mass transfer and diffusion, will be

Factors such as temperature and soil organic matter which influence soil microbial activity have been shown to correlate with the rate of .-triazine loss from the soil (... 1961, . and . 1964). More recent studies, however, indicate that microbi

Quantitative determination of triazine herbicides in soils by chemical analysis, the soil. A large amount of material has been published about the determination of residues in a variety of kinds of samples.

The fact that these herbicides are active primarily through the soil has spurred additional research on the fate of these compounds in the soil environment. One result of this research has been a deeper appreciation of the complexities
