Anyone ever hear of rabbit fertilizer? There is a guy selling it here in central Texas. They sell it for $5 a gallon mixed 1 gallon to 5 of water. Apply about 10 gallons an acre of the mix. I see some folks use it on a smaller scale for gardens and small parcels, but has anyone tried this on a hayfield? NPK values are high. Just for fun I bought 10 gallons to try on a couple acres I have behind the shop.
