Abstract
The adoption of conservation agriculture (CA) techniques by farmers is changing
the dynamics of weed communities in cereal fields and so potentially their spatial distribution.
These changes can challenge the use of site-specific weed control, which is based on the accurate
location of weed patches for spraying. We studied the effect of two types of CA (direct drilling
and harrow-tilled to 20 cm) on weed patches in a three-year survey in four direct-drilled and three
harrow-tilled commercial fields in Catalonia (North-eastern Spain). The area of the ground covered
by weeds (hereafter called “weed cover”) was estimated at 96 to 122 points measured in each year
in each field, in 50 cm × 50 cm quadrats placed in a 10 m × 10 m grid in spring. Bromus diandrus,
Lolium rigidum, and Papaver rhoeas were the main weed species.
