This one's for James Alexander-Sinclair (Blogging from Blackpitts Garden) who was apparently inspired by the automatic compost screeners featured in my "Shake yo' compost screen" post earlier this week. But he wants something "bigger and better," he says. His brain on fire, he is all pumped up to turn his many talents to the question of large-scale screening.
Well, James, in support of your efforts, I decided to share with you these possibilities.
This one's quite cute, and will fit in the back of your pick-up. However, since it has no moving parts, it's not entirely clear how the dirt you dump on top is supposed to make it through the screen (especially a screen at that angle), but I'm sure you'll figure something out: maybe instead of shaking, you can take up jumping. Of course, you can always buy the "Optional Vibrator Package" for a mere $1,400.
Portable Soil Screener. Portable as in slip it into your back pocket? The site has a video of it in action. If you have had a very dull day, check it out.
