Other claims from this paper (13)
- Intervention effect Tillage increased olive-grove soil moisture by 8% relative to unchecked weeds.
- Intervention effect Herbicide weed control with no tillage increased soil moisture by 25% over no weed control.
- Intervention effect Olive production increased by an average 16% with no tillage.
- Observation Herbicide use is common in Spanish olive groves and has rapidly increased over twenty years.
- Observation Nearly 90% of olive groves in very mountainous regions use no tillage and herbicides.
- Observation Traditional tillage loses over 80 tons of soil per hectare annually in Andalusian olive groves.
- Intervention effect Bare soil treated with herbicides without tillage erodes at half the rate of tilled soil.
- Recommendation The recommended practice keeps soil beneath trees bare and vegetative cover between rows, with spring herbicides to prevent water competition.
- Intervention effect Vegetative cover between rows significantly reduces erosion, increases infiltration and reduces evaporation.
- Intervention effect Vegetative cover between rows reduces water evaporation.
- Observation Conventional tillage erosion was 13 tons/ha in Cordoba.
- Observation No tillage with bare soil erosion was 7 tons/ha in Cordoba.
- Observation Cover crop and herbicide management eroded at less than 1 ton/ha in Cordoba.
