Lecture 25 Hay Storage
Impact of weather... Baling moisture % = 18 - 22% older equipment used to "shut you down" new equipment does not... deterioration occurs above 105o F mold & heat generation occur 113-150o F spontaneous combustion 150o F and above
Reducing Storage Losses • well drained area • on rock (large) • on tires Allow air to move • on palates • North - South Orientation - solar penetration • rows - 3 feet apart • minimizes losses to 5-10% / year... • Cover with bonnet or tarp - 5-10% reduction • divert water • dry access important too. • Expected Annual losses 1. Inside bale - 3 - 5 % DM loss 2. Outside bale 15-18 % DM loss
Storage in a building • Expected losses... • 1. 2-5% - 9 months 2. 8% - 12 months • Building Considerations • minimum 2' wider than bale width... • minimum 2' clearance to lower cord • pyramid stacking - "squat" • may only require roof • economics - savings; $/sq. Ft for purchase • $/ton 15% 20% 40 1.85 2.46 50 2.30 3.08 60 2.77 3.69 80 3.69 4.92
Building Ownership costs must be considered • depreciation (5%) • interest (9%) • insurance ( .3%) • taxes (1%) • Total = 16% 1000 # bale —> 80 # / sq. ft. • stacking against walls/poles • force considerations
