Root zone definition

Root zone means the mass of soil extending downward to the depth of the roots of the crop being grown.

Root zone means the area of the ground around the base of the tree measured from the trunk to 5 feet beyond the outer base of the branching system.

Root zone means the area around a tree measured from the trunk to a distance of two and one-half times the tree’s drip line. Under appropriate conditions, as determined by the Director of Community Services or his or her designee(s), the root zone for one or more trees may be considered to be less than the area specified above, but shall be preserved to the maximum extent feasible.

Examples of Root zone in a sentence

• Root zone soil moisture is calculated using a multi-layered water balance equation which uses snowmelt and net precipitation as inputs, and drainage and evaporation as outputs (Miralles et al., 2011).

• We even see that 52 TLDs in the Root zone have inconsistent NSSets.

• Root zone soil moisture plays a vital role in the transpiration process of evapotranspiration (ET) especially in arid and semi-arid regions, where most of the water loss is accounted for by transpiration during the dry period (Jovanovic et al., 2015; Palmer et al., 2015).

• Within the Nutri2Cycle project, we consider the farm scale as the most concise for understanding the CNP flows involved in the interactions between crop production, animal production and the role of processing installations, and the regional (EU) scale for the translation into policy decisions.The system boundaries for the impact assessment at the farm scale are defined by:- Farm gate- Air- Root zone depth, from where the loss fluxes can contaminate groundwater and / or surface water.

• Root zone temperature correlated to growth parameters such as shoot, yield, fruit fresh weight, and fruit number fitting a quadratic curve with the estimated optimum temperature for total growth of tomato of 26°C (Diaz-Perez and Batal, 2002).Enhancement of nutrient uptake of roots is thought to be a beneficial effect of raising root zone temperature.

• Root zone soil moisture is calculated using a multi-layered water balance equation which uses snow melt and net precipitation as inputs, and drainage and evaporation as outputs (Miralles et al., 2011).

• Figure 1: Root zone of kauri (3 times the radius of the outermost canopy dripline).

• Root zone leakage from non- arable land is included, as well as retention during subsurface transportation (groundwater) and retention in surface waters.

• Root zone protection devices may include such things as the installation of geotextile, gap graded aggregate, and rumble boards or corduroy.

• Root zone to be protected prior to planting either by healing into ground, covered with bare earth, hessian sacking or min 300mm of straw( adequately irrigated and kept moist to avoid roots drying).
