Summary in the original language of the document

Sheep grazing allows for the valorisation of permanent ground cover while quickly returning nitrogen fixed by WC (up to 100 Kg N ha-1) to the soil. In this way, the carbon: nitrogen balance is maintained below 15, and the nitrogen deficiency risk for the following crop is reduced. Moreover, sheep grazing regulates vole and slug populations. Under such a scheme, there is no more requirement for interventions or inputs between the rapeseed sowing and the winter cereal sowing. From the cropping system perspective, the only additional cost associated with this is the WC seeds cost.


Summary translation

Le pâturage ovin permet de valoriser la couverture végétale permanente tout en restituant rapidement au sol l'azote fixé par les WC (jusqu'à 100 Kg N ha-1). Ainsi, le bilan carbone/azote est maintenu en dessous de 15 et le risque de carence en azote pour la culture suivante est réduit. De plus, le pâturage des moutons régule les populations de campagnols et de limaces. Dans un tel schéma, il n'y a plus besoin d'interventions ou d'intrants entre le semis du colza et celui des céréales d'hiver. Du point de vue du système de culture, le seul coût supplémentaire associé est celui des semences WC.

What problem does the tool address?:The period between the rapeseed harvest and winter cereal sowing is too short to grow a summer cover crop. The regrowth of rapeseed can also be a problem, and therefore needs to be controlled following the rapeseed harvest. Moreover, carbon from the rapeseed crop residues returning to the soil needs to be managed. To do so, there is often a need to increase soil nitrogen availability following the rapeseed crop.
What solution does the tool offer?:Rapeseed is usually sown in August together with winter sensitive legumes (Alexandrian clover, lentils, field beans and peas) acting as companion plants limiting weed development. In our case, we add white clover (WC) to the seeds mixture as a winter persistent legume that will grow slowly under the rapeseed and other companion plants mixture. Due to the increase in light availability its growth will increase with the loss of the first rapeseed leaves reaching maturity. Within 2-3 weeks after the rapeseed harvest, full ground cover will have been achieved by the WC and rapeseed regrowth mixture. Sheep grazing should then take place. The mix is a very good sheep feed and the incorporation of nitrogen from the sheep manure into the soil balance the carbon-rich residues from the harvested rapeseed (maintaining the carbon: nitrogen ratio in the soil at low level).
