Other claims from this paper (7)
- Intervention effect Fertilizer placement reduced weed biomass by 55% versus broadcast application.
- Intervention effect Fertilizer placement reduced weed density by 10% versus broadcast application.
- Intervention effect Fertilizer placement increased grain yield by 28% versus broadcast application.
- Mechanism Crop competition and weed harrowing presumably interacted to produce the strong weed effects.
- Intervention effect Fertilizer placement reduced biomass of almost all frequent weed species.
- Observation Fertilizer placement affected weed density less than weed biomass.
- Observation The effects were more pronounced in 1993 than in 1994 and 1995, possibly due to dry spring weather.
