With the right conditions it can work great! You need dead duff on top, not a ton, but not too little. If you spray a month in advance and see a good rain coming then broadcast away! Last week I was tilling a half acre plot and the tiller shot craps half way through the plot. I sprayed back in early August and everything was dead. I went ahead and broadcast the non-tilled part and packed/broadcast/packed the tilled portion. Two days later we got 1.5 inches of rain followed by cooler weather so the moisture held on nicely especially with the dead thatch on top. The mix of peas, wheat, oats, rye, and forage radishes should be full on germinating nicely now.
