Effects of Crop Canopies on Rain Splash Detachment
Crops are one of the main factors affecting soil erosion in sloping fields. To determine the characteristics of splash erosion under crop canopies, corn, soybean, millet, and winter wheat were collected, and the relationship among splash erosion, rainfall intensity, and throughfall intensity under different crop canopies was analyzed through artificial rainfall experiments. The results showed t...

متن کاملModelling the Light Environment of Virtual Crop Canopies
Virtual plants describe functionally and geometrically plants as sets of interconnected organs. As many plant processes are driven by light, virtual plants require the estimation of the light absorbed by each organ. This has motivated the development of dedicated light models taking profit from the 3D geometry provided by virtual-plant models. We first introduce the principles governing the phy...
متن کاملEffects of chlorophyll concentration on green LAI prediction in crop canopies: Modelling and assessment
A growing number of studies have focused on evaluating vegetation indices in terms of their sensitivity to vegetation biophysical parameters as well as to external factors affecting canopy reflectance. In this context, leaf and canopy radiative transfer models have provided a basis for understanding the behaviour of such indices, particularly their resistance to external perturbing effects rela...
متن کاملScaling Effects of Standing Crop Residues on the Wind Profile
velocities for soil erosion supports management guidelines (Hagen, 1996; Nielsen and Aiken, 1998; McMaster Standing senescent stems increase the aerodynamic roughness of et al., 2000). Effects of standing stems on eddy diffusion the surface, reducing wind energy available for momentum transfer at affect convective transport of heat, water vapor, and the soil surface, such as for wind erosion, a...
