1. Sorption/desorption and leaching of the herbicide ametryne in soils cultivated with sugar cane and amended with sewage sludge / Sorção/dessorção e lixiviação do herbicida ametrina em solos canavieiros tratados com lodo de esgoto
Several studies have shown the benefits of applying sewage sludge on the physical and chemical properties of the soils. However, just a few of them evaluates the impact of this practice on the behavior of pesticides in tropical soils. The main goal of this research was to evaluate the effects of applying different sources of sewage sludge (Ribeirão Preto, F

2. Modelagem de lixiviação do herbicida picloram atraves de lisimetro de drenagem sob vegetação de Brachiaria decumbens / Modeling of picloram herbicide leaching in a lysimeter under Brachiaria decumbens vegetation
Picloram is one of the most used herbicides in the control of weeds in pastures areas, especially the ones of difficult eradication. Many are the stories of wells and springs contamination with herbicides residues as a result of its leaching in grounds. Due to the lack of knowledge and available data on the destination of the picloram in brazilian grounds, r

3. InfluÃncia da polaridade de pesticidas nÃo-iÃnicos sobre sua sorÃÃo em um latossolo. / Influence of the polarity of non-ionic pesticides on theirs sorption by a Latosol.
The sorption of thirteen non-ionic pesticides, with varying n-octanol/water partition coefficients (Kow), by soil material taken from the A horizon of an Acriferric Red Latosol was investigated. Sorption isotherms of the pesticides were determined by the shake-flask method. The amount of chemicals in aqueous solutions was measured by HPLC with UV detector. S
