A report ended up being undertaken to research the result of soil and lawn address, whenever incorporated with water dining table administration (subsurface drainage and managed drainage), in reducing herbicide residues in agricultural drainage water.

Twelve PVC lysimeters, 1 m very long and 450 mm diameter, had been full of a sandy soil and utilized to analyze the next four remedies: subsurface drainage, managed drainage, lawn (sod) address, and soil that is bare. Contaminated water atrazine that is containing metolachlor, and metribuzin residues had been put on the lysimeters and examples of drain effluent had been gathered. Significant reductions in pesticide levels had been present in all remedies. When you look at the first 12 months, herbicide levels had been paid down notably (1% degree), from on average 250 mg/L to lower than 10 mg/L . When you look at the 2nd 12 months, polluted water of 50 mg/L, that is considered more practical and reasonable in normal drainage waters, had been put on the lysimeters and herbicide residues when you look at the drainage waters had been paid down to significantly less than 1 mg/L.
