This project has demonstrated that simple oversowing techniques can be used in a wide variety of grassland conditions throughout northern Germany to introduce white clover into permanent pasture and consequently avoid the necessity to plough and re-seed to establish clover dominant pastures.
The results confirmed already published research results which emphasised the importance of having sufficient bare ground in which to place introduced seeds when employing simple oversowing techniques, as used in the present project, to upgrade existing pastures. The success rate with very dense swards was low which led to the conclusion that oversowing using simple one-pass machines may not be the most appropriate way to introduce clover into such pastures.
On the basis of the oversown swards a calibration for a sward height measure was developed which allows estimating the yield of swards by means of the sward height. The technique showed a good agreement between calculated and observed yields over a wide range of sward types.
The results obtained from the project will be particularly valuable to the increasing number of farmers throughout Germany converting to organic farming where reliance on legumes and grass/legume mixtures is of paramount importance in successful organic grass based livestock systems.
Farmers taking part in the EFFECT project will function as multipliers and spread their skills and knowledge about "Oversowing of white clover" on farmers meetings in the future. The group developed in the EFFECT project including farmers and CPL will continue to exist and form the basis for future activities in this field.
The outcome of the project will be used in teaching agricultural students at University.
Demonstrations of the technique and visits of the project fields will continue.
Leaflets, copies of project publications, PowerPoint presentations and videos will be spread to all interested units with the support of the agricultural chambers and extension services in Germany. It will be used in farmers teaching courses and for advisory work by the German extension service.
A website (www.grassland-organicfarming.uni-kiel.de/effect_projekt.html) will be maintained in the future and function as a platform, on which people can discuss, exchange experiences and contact CPL. This website is written in German and is aimed at farmers, advisory people, politicians and the broad public interested in this field. A link to the official EFFECT homepage will extent the circle of communication.
