Ms. Daisy;
I use a MEAN rototiller when I first break ground, the clay pretty much demands it, but when that's done, I'll dig a big furrow in the middle of my work lengthwise and as deep as I can, then put down the perlite. After mixing with my pointed or forked hoe I can come back one more time with the rototiller. This ensures a good mix, but to a certain degree, you're right some does fly or float off, but I was lucky enough to ( accidently ) design my beds to catch on one what the other loses especially on the leaward side of these danged winds which also happens to be the lowest area in my veggie garden so rain caused runoff ALSO collects in the same spot. Needless to say my eastern beds are more accommodating to root crops than the western ones - I'm one of those that makes A LOT of lemonade!
