Plastics are widely used in agriculture to preserve, transport, package and market agricultural products. However, agricultural activity is one of the main sources of plastic waste in the soil, including microplastics (MPs), which have significant ecological impacts, such as threats to soil fauna and the ability to concentrate organic pollutants. The interaction of MPs with residual herbi…
This project will investigate the transport of the herbicides S-metolachlor and hexazinone in soils modified with aged microplastics, simulating leaching in the laboratory. Soil columns will be used to measure how these herbicides move vertically under a simulated rainfall regime of 200 mm in 48 hours. The herbicides will be applied to the top of the soil and, after the experiment, the co…
This project will investigate how the presence of aged microplastics in soils affects the sorption (retention) and desorption (release) processes of two herbicides, S-metolachlor and hexazinone. The soil will be collected from a non-agricultural area with no history of herbicide use, amended with 10% aged microplastics, and tested for its capacity to sorb and release these herbicides. The…
This project aims to study how microplastics (small polyethylene beads) change after aging in an ultraviolet light simulator, which mimics the effects of sunlight, heat and humidity. The material will be analyzed before and after aging to understand how its chemical and physical properties change over time. The analyses will include the composition of elements such as carbon, oxygen and h…

Glyphosate is a broad-spectrum herbicide applied in post-emergence and non-selective, being the most widely used in the world. In view of the exportation, the addition of biochar (vegetable charcoal) has gained recognition for its high sorption capacity of herbicides, influencing the bioavailability and residual effect in the soil for weeds, interfering negatively in the chemical manageme…
Residues of quinclorac herbicide cause phytotoxification to sensitive crops in rotation with rice, due to the high persistence of the product in the soil, a phenomenon known as carryover. There are no studies in the literature that relate quinclorac persistence and carryover to soil, which are essential properties to avoid phytotoxification in rotational crops. The objective of this resea…
The application of biochar to soils has been known for some time to increase herbicide sorption and reduce efficacy. Overall, there is the assumption that increased soil sorption could reduce leaching of herbicides to groundwater, thus improving overall water quality. On the other hand, increased sorption leads to decreased efficacy of soil applied herbicides thereby eliminating the resid…

Soil is the final fate of the herbicides applied in weed control in crops, so the study of the soil-herbicide interaction is essential for the comprehension of its behavior. Glyphosate is an herbicide non-selective, applied in post-emergence and have a broad-spectrum, being the most widely used in the world. The aminomethylphosphonic acid (AMPA) is one of the primary degradation products …
The mixture of herbicides is a widely used technique in weed control in various crops such as maize. However, this type of interaction resulting mixture is a matter of constant concern and research, particularly of the herbicide in the soil retention capacity that directly influences the final destination of these molecules in the environment. The many advantageous properties of biochar h…
