I'd just bubble the Alfalfa if it were me. The anaerobes just smell a little.
That lobster compost for sure but the Chitin system will take a while to get in gear. For now, can you get some quality Neem Meal or oil?

Works fast.
bad smell - Lacto B is our friend there. I've been adding a bit to every tea I brew. Getting positively DELICIOUS smells even off tea with positively shitty smelling stuff going in. Also really easy to get a whole ton of it. For guys that don't know how yet:
Soak brown rice in an open bowl in a cool area, about 2 ft off the ground, for about 3 days. Soon as it gets a slightly milky colour to it and bit of a smell, strain rice off. Add this microbe-rich rice water to up to 20 times the volume milk (doing this in a separatory funnel is the best way) and wait a few days until the milk becomes two layers, top being white curds, bottom a yellow liquid that will be a pretty pure Lacto Bacilii serum. Seperate yellow serum from curds, with a separatory funnel it is a case of opening the bottom tap. Dilute this serum with equal amount sugar mix (blackstrap molasses for you guys that can find it, diluted with 1/3 water) to keep your bacteria alive and multiplying. Should have a sickly sweet plus sour milk smell at that point. This is your 'pure serum' you will be working with. For most purposes dilute 20 parts water to one part serum. In a tea even less will do just fine.
Perfect for soil rehab where salt-based ferts were used, and where anaerobic activity is creating ammonia, Lacto B will change ammonia into useful nitrates.
Lacto Bacilii is my new workhorse bacteria friend. We are really becoming good buddies, me and Lacto B. I just used a spray of it on my neighbour's stinky pile of cow shit. Smell gone. Thank GODS. I was getting ready to sue him over it, seriously. So instead I just snuck in and did the job. Amazing stuff.
