Using Canopy Reflectance and Crop Stress Index to Enhance Wheat Yield Prediction
Canopy reflectance can be useful indicator of crop health status. Canopy stress index (CSI) is usually expressed as canopy temperature minus air temperature, and this value is higher and a positive number in a well irrigated wheat field. Three main...
Riparian vegetation classification from airborne laser scanning data with an emphasis on cottonwood trees
Incorporated ALTM 1233 (Optech Incorporated, Toronto, Ont.), during flyovers conducted at an altitude of 750 m. The lidar
data were preprocessed to create a two-band image of the study site: a high-accuracy canopy altitude model band, and a...
Common bean canopy characteristics and N assimilation as affected by weed pressure and nitrogen rate
Crop canopy characteristics and management factors that affect the canopy structure can influence crop competitive ability against weeds. The goal of the current study was to understand the interaction between nitrogen (N) fertilizer rate...
Lidar Remote Sensing for Forestry and Terrestrial Applications
dimensional structure of the forest canopy. Ecologists
have long understood that the presence of specific organisms and the overall
richness of wildlife communities can be highly dependent on the threedimensional
spatial pattern...
Drought resistance and soil water extraction of a perennial C4 grass: contributions of root and rhizome traits
Partial defoliation and runner removal affect runnering, fruiting, leaf photosynthesis and root growth in â€کToyonoka’ strawberries for subtropical winter production
Effect of natural land covers on runoff and soil loss at the hill-slope scale
of Khorasan-e Razave Province in the north-eastern Iran. Data acquired from 2008 to 2015 include slope, aspect, soil texture and land covers (canopy and litter) factors that were selected as main natural factors and it was tried to determine the effects...
Sequence of facilitation, allelopathy and competition between an aridland shrub and grass within a single growth season
assessed on the grass germination and seedling growth. Available soil water were measured in three soil depths at the vegetative, flowering and seed ripening growth stages of the grass. Grass seeds were sawn under the canopy of shrub...
