Figure 3. A multi-year Purdue study found that the highest alfalfa yields were recorded when fertilizer rates were 50 pounds of P 2 O 5 per acre per year, and 200 pounds or more of K 2 O per acre per year.igure 3.

So, even though they only need to take in about 4 pounds, I would probably plan on feeding more. But for the purposes of this discussion, letâs use 4 pounds. 4 pounds times 50 goats = 200 pounds a day. Times 365 days in a year = 73000 lbs. a year, or 36.5 tons. That is a lot of alfalfa! But alfalfa is a very nutritious feed.
