I just purchased 10lbs of Shotplot brassica mix for $42.00 w/shipping. Throw in some Milorganite when it goes on sale and I will have another $6. And then a bag of Urea at a cost of $15. As for gas I use a Polaris 850 to pull my Tufline disc so it is not much, maybe $5. I use the cheap 41% glyfosate from Walmart at a cost of $15. I may add some clover to the Shotplot for 2014. I plant about 2acres so all this seed will be enough for 2 years. All combined per year I may spend as much as $65.
