Attention to detail can maximize forage quality | Crop ...

Sep 05, 2020· Forages should be cut at 2.5-3 inches in most conditions to maximize yield and stand longevity. Shorter cutting height results in slightly more yield but decreases quality. Cutting shorter than 2.5 inches increases soil contamination of forage (ash) and shortens stand life of grasses.

Blast furnace - Wikipedia

Blast furnaces operate on the principle of chemical reduction whereby carbon monoxide, having a stronger affinity for the oxygen in iron ore than iron does, reduces the iron to its elemental form. Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and ...
