tilling under in the ground in the spring? To break up clay soil and hopefully improve it? Or on top of grass and mowed over as a sort of mulch/fertilizer? I have been finding a lot of it thrown away in dumpsters and "rescuing it"...I don't know if it is expensive to buy, but free is the cheapest of all...guess I am becoming a hoarder...hard to quit dumpster diving when you find usable stuff...and lots of pumpkins for the seeds...also addicted to craigslist "free " stuff and curb alerts...LOL..Help! I can't stop!! growing some alfalfa with the straw wouldn't be bad...I could use it as grass in smoothies and seeds in sprouts?.... I put a couple of bales on the side lot of grass in the condo area and they mowed over it...hope it will help the grass..now tonite I got 4 more bales and put in my back patio...I had to use a small step stool and climb into the dumpster to get them out..but I hate to see stuff wasted... Actually it doesn't smell like straw, it smellls like beer...maybe someone was drinking while celebrating Halloween?
