Other claims from this paper (11)
- Association Soil under older apple trees was cooler than under young trees, by 4-11°C in daily accumulated temperature.
- Association Moisture storage under old apple trees was higher than in a younger orchard.
- Mechanism Reduced evaporation and transpiration under older apple trees are assumed to explain their higher moisture storage.
- Observation The younger apple orchard needed irrigation rates of up to 1400 t/ha per metre of soil depth.
- Observation The younger apple orchard needed irrigation of 450 t/ha in the arable layer.
- Observation Productive moisture storage in the old-aged orchard stayed at the good rank until mid-August.
- Observation Productive moisture storage in the old-aged orchard dropped to the poor rank only in September.
- Observation Under 1996 apple plantings in 2005, a significant moisture deficit of 49 mm appeared in the upper 20 cm layer by early June.
- Observation The water regime under the 1996 apple plantings in summer 2005 was more intense throughout the soil profile.
- Association In the old-aged orchard, the amount of available moisture and its deficit changed to a lesser extent over the years.
- Association With tree age, fluctuations in the hydrothermal regime during the growing season decreased.
