Good practices promoted aims at reducing polution, and preserving ground functions, without additional financial cost for the farmers.
These practices are:
2) Direct sowing of crops by abandoning deep plowing. This practice helps to preserve the life of the soil.
3) Establishment of intercropping, and relay cropping allowing a natural supply of organic matter. These green manures add organic matter to the soil, especially nitrogen, while giving it a good structure through its root system. (By this way, chemical nitrogen intake can be limited in the next year of crop production). Some sewing can be done by helicopter before harvesting rice.
4) Limitation of the use of phytosanitary products in arboriculture, gardening and viticulture, by the adoption of alternative practices: use of protective nets, management of grazing, etc.
5) Integration of grazing in crop rotations. The grazing of green manures or crop regrowth has an impact on the destruction of weeds present in the soil. Weeds consumption by cattle or sheep replace chemical destruction. This practice also meets a social need of local breeders to find grass for their animals.
The main beneficiaries are farmers, ranchers, managers of natural areas and the territory as a whole.

Resources needed

Recruitment of a full-time employee for a year ;
Fund for the organization of 5 field days and training on the various topics

Evidence of success

We are currently quantifying the reduction in fuel consumption, the use of chemicals and phytosanitary products related to all these practices. Some farmers totally stop these products, using grazing of weeds after flooding following crop harvest for some of them, or using technical weeds destruction for others. Some of them choose to limit passage of tractor, to 4 times a year.

Difficulties encountered

Involve as many farmers in the Park area as possible in testing those practices ans finally adopt them. In 2019 a group of 10 farmers in the Park, DEPHY’s group, will try for the first time direct sowing, abandoning deep plowing, and will test new varieties of intercropping and grazing.

Potential for learning or transfer

To date 4 training-courses / field visits have been organized bringing together an average of twenty farmers, different in each of them (80 farmers involved). A group of 15 farmers already identified (named DEPHY group) ensures the dynamics of the exchanges and proposes to carry out the experiments to come.
