Abstract
The maintenance of the grass cover in walnut orchards facilitates the work of the harvester and allows convenient access to the plot.
The main problem observed on the inter-row is the compaction of the soil caused by the regular passage of machinery.
This inter-row can be conceptualized differently to limit the phenomenon or even improve the profitability of the plot.
Results of trials conducted in GREENCOQ project showed that, in young orchards, a rotation of two successive crop covers, field beans sown in the fall followed by fodder sorghum sown in summer, making it possible to increase the organic matter rate.
In the same project, in mature orchards, a cover crop, sown in the autumn, suggested improvement of the microbiological activity of soil, soil decompaction and nitrogen supply and the opportunity to reduce the use of chemical fertilizers.
