| 10 tons and 7 cuttings. About 10% bloom is normal for cutting. This is irrigated alfalfa in California's Southern San Joaquin Valley and it takes about 6-8 inches of water per cutting. That is about $40/ton of alfalfa just for water. I use this for a removal rate on fertilizer. http://back-to-basics.net/cnu/index.htm Even though I believe that it is a mistake, I can not choke down the cost of 600 lbs/acre of potash. That gets about 1/2 of the removal rate. P and K are put on after the 6th cutting. We also try to put on 3 ton/acre of composted steer manure in early winter. The composting process helps kill most of the the weed seeds that are in raw manure. Clean alfalfa is usually important, this year seems to be an exception. | |
