| The morphological diversity of leaf surface and structures such as trichomes, stomata, cuticle, and waxes that exists among plant species can have great influence on the adherence and deposition of spray droplets, as well as on herbicide absorption. The aim of this research was to study leaf pH and to evaluate wetting areas after applications of solution surfactants on the following aquatic weeds: Enhydra anagallis, Eichhornia crassipes, Heteranthera reniformis, and Typha subulata. The aquatic weeds were grown in reservoirs containing water under open air conditions and their leaf tissues were collected when the plants reached full development (before flowering). The mean leaf pH varied between 5.50 and 7.50; E. anagallis should be pointed out for... |

| Biochar is considered as an option to ameliorate soil functions, by improving soil physical and hydraulic soil properties. This study investigated the effect of biochar and of wetting and drying cycles on the water infiltration at laboratory and at a hypothetical watershed scenario. In the laboratory, test samples with 2.5 and 5% (by dry mass) of a mango-wood biochar were added to a sandy and sandy loam soil material. Cumulative infiltration was determined after simulated intense wetting and drying cycles, by drying the samples at 30°C for three consecutive days. Additionally, biochar amended soil hydraulic parameters, obtained at the laboratory, were used to simulate the water discharge of a hypothetical watershed, with the Soil and Water Assessment Tool... |
