  • Analysis of Selected Herbicides And Related Metabolites in a Coastal Lagoon Under The Influence of Water Runoff: Sediment and Biota

    Coastal lagoons are subjected to strong anthropogenic pressures as a consequence of their location between Land and Sea. Among other contaminants, they are receiving high nutrient loadings and pesticides, mainly of agricultural origin, from heavily exploited watersheds. Since the number of chemicals released into the water systems is high, there is a need to classify them and the associated risk, ...


  • Method for irrigation scheduling based on soil moisture data acquisition

    The water requirements of crops are dependent on evapotranspiration (ET), soil chemistry, and the crop’s maximum allowable depletion (MAD). Direct measurements of root zone soil moisture, water application along with published ET values and soil textures, can be used in a soil water balance model that can significantly optimize irrigation efficiency. Over the past five years, advancements in ...

  • Subsurface drip and overhead irrigation: a comparison of plant boll distribution in upland cotton

    Although subsurface drip (SSD) is used as a water-efficient alternative to overhead irrigation in many crops, the effects of SSD on the distribution of bolls on cotton plants (Gossypium hirsutum L.) have not been thoroughly examined. The purpose of this study was to add to the current knowledge about the effects of SSD on cotton yield dynamics. Cultivar DP 488 BG/RR was grown in three studies ...
