dc.description.abstract | Herbicides had been commonly applied by farmers to retain their harvest. On its application, we should consider the persistency and amount of its residue in soil and surrounding environment. The more persistent the herbicides in the soil, it will increase the effectivity of its formula to kill weeds. However, it also might cause some serious environmental damage and water pollution. The aim of this research were (a) to study the pattern of concentration change of oxyfluorfen residue in Latosol Dramaga and the influence of soil factors and rainfall on its concentration, (b) to measure the residue concentration of oxyfluorfin in soybeans. | id |
