The use of herbicides is a fundamental part of the current agricultural model, and without the use of these products it would likely be unfeasible to guarantee food security worldwide. On the other hand, these products have a series of environmental and social impacts, which demand a constant concern on the part of society. Soil
is the final fate of herbicides applied in agriculture in the soil–plant system. When they come into contact with the soil, herbicides are subject to a series of physical–chemical processes that regulate their fate and behavior in the environment, which is extremely complex. The use of biochar in agricultural soils as fertilizer and soil conditioner
has been further explored; however, little is known about the effect of this material on soils contaminated with herbicides, and little is known about its effect on weed control as well. The fate and environmental behavior of certain herbicides, as well as their efficacy when applied directly to the soil, such as pre-emergent herbicides
with residual action, are strongly influenced by the retention bond with soil particles and organic carbon content. Therefore, the addition of biochar to the soil can easily potentiate the herbicide retention process, which, in addition to contributing positively to the reduction of chemical contaminants in the environment, can exert negative effects on herbicide behavior and effectiveness of these products in weed control. Thus, this book highlights the physical and chemical characteristics of biochar, which can impact on the sorption–desorption, runoff, leaching, and hence efficacy and degradation of herbicides. Furthermore, the removal of herbicides in
water is also evidenced with the addition of biochar.
