However, in certain olive-growing regions, due in particular to the high number of crop declarations, ongoing restructuring of olive groves or other specific circumstances, the above dates are no longer appropriate for the purpose of controls.

Tractors designed for working with high-growing crops e.g. vines.

Beet growing in that area is essential in order to regenerate soils with a particularly high level of clay and thus to avoid a return to single-crop farming;

Due to the inherently higher level of homogeneity in residues arising from post-harvest treatments or protected crops, trials from one growing season will be acceptable.
