Key Tips to Help Silage Quality and Yield
Patrick Cashman | Goldcrop Limited
When to mow silage is an important consideration when maximising both silage quality and silage yield.
- Too soon and the crop may not have reached its full growing potential.
- Too late may cause an excessive accumulation of stem and dead material which can be detrimental to silage quality.
- Targeting the crop when 50% of the ears have emerged will give the best combination of silage quality and yield.
After a good wilt of 24 hours
- It is important to get the chopped grass into an air-tight environment as quickly as possible.
- Getting the silage well packed and covered with robust covering as quickly as possible will achieve this.
- Extra effort here will reduce wastage during winter and lost feed
Once silage in harvested
- It is important to consider the yield and if some areas are offering disappointing performance.
- Lost silage yield can lead to forage shortages in future with resulting additional cost to buy feed.
- Some investigation can tell if soil nutrients are deficient or if some silage areas need reseeding. Reseeding can offer a really good return in silage ground by returning larger quantities of better-quality home-grown feed.
