Other claims from this paper (13)
- Intervention effect Shrub presence improved or did not affect crop yields in three of four years.
- Intervention effect Millet biomass increased with shrub presence.
- Intervention effect Peanut biomass increased with shrub presence.
- Intervention effect Millet P uptake increased with shrub presence.
- Intervention effect Millet biomass increased with fertilizer rate.
- Intervention effect Peanut biomass increased with fertilizer rate.
- Intervention effect Millet N uptake increased with fertilizer rate.
- Intervention effect Millet P uptake increased with fertilizer rate.
- Observation Soil inorganic N reached very low levels by the end of the season.
- Observation N content of soil leachates was generally lower beneath shrub canopy than outside.
- Intervention effect P. reticulatum increased soil particulate organic matter.
- Mechanism The authors infer that shrubs conserve N otherwise lost by leaching.
- Recommendation The authors conclude shrub management has soil and nitrogen-loss benefits in the Sahel.
