High Throughput Determination of Plant Height, Ground Cover, and Above-Ground Biomass in Wheat with LiDAR
Crop improvement efforts are targeting increased above-ground biomass and radiation-use efficiency as drivers for greater yield. Early ground cover and canopy height contribute to biomass production, but manual measurements of these traits, and in particular above-ground biomass, are slow and labor-intensive, more so when made at multiple developmental stages. These constraints limit the abilit...
متن کاملEstimation of Winter Wheat Above-Ground Biomass Using Unmanned Aerial Vehicle-Based Snapshot Hyperspectral Sensor and Crop Height Improved Models
Correct estimation of above-ground biomass (AGB) is necessary for accurate crop growth monitoring and yield prediction. We estimated AGB based on images obtained with a snapshot hyperspectral sensor (UHD 185 firefly, Cubert GmbH, Ulm, Baden-Württemberg, Germany) mounted on an unmanned aerial vehicle (UAV). The UHD 185 images were used to calculate the crop height and hyperspectral reflectance o...
متن کاملAbove-Ground Biomass and Biomass Components Estimation Using LiDAR Data in a Coniferous Forest
This study aims to estimate forest above-ground biomass and biomass components in a stand of Picea crassifolia (a coniferous tree) located on Qilian Mountain, western China via low density small-footprint airborne LiDAR data. LiDAR points were first classified into ground points and vegetation points. After, vegetation statistics, including height quantiles, mean height, and fractional cover we...
متن کاملSugarcane Root Growth and Relationships to Above-ground Biomass
Roots comprise the lesselknown part of the soil-plantatmosphere continuum and yet are essential to the supply of sufficient water and nutrients to ensure u successt'ul crop. By understanding the growth and distribution of sugarcane roots. yields can be optiniiscd through improved strategic decisions. 'This paper addresses root growth and rclationships to above ground biomass. lssues discussed i...
متن کاملTesting the Growth Rate Hypothesis in Vascular Plants with Above- and Below-Ground Biomass
The growth rate hypothesis (GRH) proposes that higher growth rate (the rate of change in biomass per unit biomass, μ) is associated with higher P concentration and lower C:P and N:P ratios. However, the applicability of the GRH to vascular plants is not well-studied and few studies have been done on belowground biomass. Here we showed that, for aboveground, belowground and total biomass of thre...
