Packing Silage – Get It Right
Wisconsin Crop Manager Crops By WCM Staff on 4/27/2006 8:21 PM
Proper filling of bunkers and piles of forage pays big dividends. Dry matter losses occurring during filling, storage and feedout will be higher in silage packed at low density (< 14 lbs DM/Ft3). Higher density also allows more feed to be placed into a silo, thus reducing the cost of additional storage capacity.

Drying Forage for Hay and Haylage
Wisconsin Crop Manager Crops By WCM Staff on 4/26/2006 8:14 PM
If we understand and use the biology and physics of forage drying properly, not only does the hay dry faster and have less chance of being rained on, but the total digestible nutrients (TDN) of the harvested forage are higher. As mowing and conditioning equipment has evolved, some of the basic drying principles of forage have slipped by the wayside and we need to review them.

Wisconsin Crop Manager Weeds By WCM Staff on 4/21/2006 5:21 PM
The recent warm weather and rain is bringing a good crop of winter annual weeds to life and early summer annual weeds will be right behind.
