in years past and they seem to have cut down tremendously on the aphid population. Though, if you're battling aphids, you first have to get rid of ants. For that, I've used beneficial nematodes. That's a sloooow boat to China, but it does work. You might check out sites like BugLogical for insect predators, if you're interested in doing the green/sustainable/no-chemistry thing. I've used BugLogical and they're quick to ship and the predators come live and healthy (you haven't lived until you've released a thousand ladybugs in your back yard :) )
As for the manure, I'd suggest using 6-year-old composted manure this time of year. I'm lucky enough to have 8-3/4 acres of land ... but if you've got neighbors, they probably wouldn't appreciate green (fresh) manure being applied to your garden. The stank can be right potent; worse in the heat of summer. If you do want to use green manure, I'd suggest waiting until fall when you can till it in with your tiller to work over winter.
This year I'm doing sort of a modified lasagna garden, doing a good bit of my composting in the furrows. I'm using a spring-cutting alfalfa hay, coffee grounds, tea bags, veggie waste (no meat), other gardening leftovers and paper shreds to get it started. I've done this with some success in town; now I'm trying it on a larger scale now that I've moved back to the country. So far, I'm pleased with the results.
Note: if you're going to use hay as a slow-release nitrogen source, stick with the earliest spring cutting you can get, else you'll wind up introducing an amazing amount of weeds. With any hay or straw, you're going to get SOME weeds. If you use a thick enough layer, what weeds you'll get with a spring cutting are easily pulled up. Lay those root-up in the furrows to dry. That adds to the composting mass. Every teensy bit builds up. The other benefit is that you'll need to water less often since the water you do provide won't be evaporating right back out of the ground. Tomatoes, cucumbers, watermelons and cantaloupes all seem to like having their roots shaded as well.
As for recycling, all that crap that shows up in the mailbox, along with old bills and statements you've already dutifully scanned and saved to CD (right?!?) makes wonderful compost-fluff and mulch. The shreds don't go to the landfill; help increase the acid in the soil for acid-loving plants; and if you tuck the shreds around plant bases then water immediately, they don't blow anywhere. They just stay put and keep grass and weeds from choking your favored plants. Amazingly, even after the shreds have matted down a bit, you can turn a hose right on them and the water goes right through -- and stays there. I've found that even though grass and weeds won't penetrate the mat, my bamboo, blackberry and raspberry canes don't seem to have a problem.
Hope this helps, or gives you some ideas.
