A simple and rapid direct injection method for the determination of glyphosate and AMPA in environmental water samples
(Springer Verlag, 2018-12-10)Glyphosate is currently the most widely used herbicide in the world, yet screening of environmental waters for this chemical is limited by the need for specialized derivatization and measurement methods that can be tedious ... -
A time-window within the grain filling period accounted for early leaf senescence in maize under sink limitation
(Elsevier, 2024-01)In annual crops such as maize, assimilates demand exerted by grains converges with increasing leaf senescence. As sink demand changes as grains growth, leaf senescence could also be affected during the grain filling period. ... -

Adequate vegetative cover decreases nitrous oxide emissions from cattle urine deposited in grazed pastures under rainy season conditions
(Nature Publishing, 2019-01-29)A decline in pasture productivity is often associated with a reduction in vegetative cover. We hypothesize that nitrogen (N) in urine deposited by grazing cattle on degraded pastures, with low vegetative cover, is highly ... -
Administration of equine Chorionic Gonadotrophin (eCG) to rams to improve the reproductive performance during the non-breeding season
(Elsevier, 2020-06)In most ram breeds, there are annual changes in testosterone serum concentration and semen quality. This study aimed to determine if eCG administration to rams during the non-breeding season improves the reproductive ... -
Adsorption and mobility of glyphosate in different soils under no-till and conventional tillage
