Other claims from this paper (8)
- Observation Most olive root development occurred in the first two to four years, with 70% of roots in the top 20-40 cm.
- Observation Maximum root density occurred at 20-40 cm depth and 0.4 m from trunks.
- Recommendation Water and fertilizer should be supplied at the identified root depths and distances.
- Association Canopy and root areas had a significant linear relationship with r = 0.94.
- Observation The optimum root length to leaf canopy area ratio was 2.3 km m-2 in a six-year-old tree.
- Method / resource A canopy-cover and root-extension model permitted precise estimation of water needs.
- Method / resource Canopy cover was easier to measure than root-covered surface.
- Method / resource The FAO method overestimated water needs for young trees.
