Registered dose of herbicides may be higher than rate required for controlling weed species depending on growth stages. In order to study the effect of individual post-emergence application of 2,4-D plus MCPA and three sulfonylurea herbicides at four- to six-true leaf stage of weeds, experiments were conducted in 2011 at the greenhouse of Agricultural Faculty of Ferdowsi University of Mashh...

Landsat imagery was used to study the relationship between a remotely sensed burn severity index and prefire vegetation and the postfire vegetation response related to burn severity within a 1986 burn in interior Alaska. Vegetation was classified prior to the fire and 16 years after the fire, and a chronosequence of remotely sensed vegetation index values was analyzed as a surrogate of vegetati...

Atrazine is a white, odorless powder (when pure) that is used as an herbicide to stop the growth of broadleaf and grassy weeds in crops such as corn, sugarcane, sorghum, pineapples, and macadamia nuts. It is not found naturally in the environment. It is moderately soluble in water, but is more soluble in organic solvents such as acetone, chloroform, and ethyl acetate. More than 37,000 tons of a...

The objective of this study was to verify the accuracy tree species identification using deep learning with leaf images broadleaf and coniferous trees in outdoor photographs. For each 12 eight species, we acquired 300 photographs leaves used those produce 72,000 256 × 256-pixel images. We Caffe as framework AlexNet GoogLeNet algorithms. constructed four models that combined two patterns: one fo...

Broadleaf or conifer forest? – an ongoing dilemma as regards water resource and flood prevention. Although trees use less are hydrophobic, existing studies at the watershed scale have shown varying results due to variability in meteorological conditions forestry practices. In this study, two adjacent headwater catchments [2.42 ha cypress (CF); 2.08 mixed-broadleaf (MB)] were gauged. The study a...
