[QUOTE="Angie @ DLF, post: 6944190, member: 148947"] [COLOR=rgb(65, 168, 95)][SIZE=7][B]Overseeding pays off[/B][/SIZE][/COLOR] [SIZE=5]Open swards yield too little[/SIZE] Overseeding using the correct mixtures and machinery designed for the job is now accepted as good practice to both maintain the physical and nutritional quality of medium and long term swards. When the sward becomes open allowing weeds and unsown species to invade overseeding will quickly check this and maintain the productivity by increasing both yield and quality. [ATTACH type="full" alt="before overseeding .jpg"]880144[/ATTACH] [ATTACH type="full" width="241px" alt="after overseeding .jpg"]880150[/ATTACH] Typically after 3 years of production, a leys productivity falls so the loss of 2 tonnes dry matter per hectare at 11mJ/kg equates to 18000mJ/Ha of energy. In order to replace this lost forage production with concentrate would cost roughly £145 per acre. An overseeding mix and application typically cost less than half this. A 200% return for overseeding in the first year! Overseeding a sward with the correct mixture will help maintain the swards optimum production.
