It looks like there was a lot of noise about 3 years ago about the technology and now nothing, and as far as I can find Becks didn't publish the results from their trial?? To me it seems suspiciously quiet. Either they got bought out (I can see Precision planting going after them), it ended up being a complete dud (which seems unlikely given the university studies showing promise and the silence from PFR), or they were forced to hide or close down for some other reason.
