Important factors include the depth of planting, the rate of planting, and the spacing both between rows and between plants within a row.
The affected plant may have received treatment different from nearby healthy ones watering, fertilizing, pest control, pruning, or depth of planting are examples.
Horizontal bars on central axis represent depth of planting of cuttings (C, 0.3 m), stakes (S, 0.5 m) and poles (P, 0.8 m).
We determined depth of plant water uptake, groundwater level and vegetation structure on five different locations along a topographic gradient in the highlands of Central Brazil.
To estimate the depth of plant water uptake in the different slope positions we relied on comparisons of hydrogen and oxygen isotope ratios of plant stem water, water from different soil depths, from groundwater and from rainfall.
We measured the δ2H and δ18O signatures of plants, soils, groundwater and rainfall, determining the depth of plant water uptake and examining variations in water uptake patterns along the gradient.
The depth of plant litter increased 1 − 2 cm in both habitat types when livestock grazing was absent, along with minor changes in soil carbon, nitrogen, and bulk density.
It is concluded that mean slip ratio of compacting wheel 1 is 4.44%, wheel 2 is 5.58%, wheel 3 is 7.81%, and wheel 4 is 6.96%; mean depth of planting is 29.72 mm, and mean variability coefficient of planting depth is 6.39%.
Non- or minimum-invasive methods for the quantification of rooting depths of plants are rare, in particular in (semi- arid regionsemi- aridis inforegions is crucial for the parameterization of SVAT (Soil–Vegetation–Atmosphere Transfer) models and understanding of processes within the hyetological cycle.
