| great info floated out there already about finding limiting factors.
When it comes to Becks or any other trial it all comes down to data. the more data the more sure you can be of the results. Becks does not (or at least ive never seen) them release any hard data. such as number of replications or P vaules. The P value of any true study tells you how sure you can be that product X really is responsible for the 2bu/acre gain you saw vs pure chance. (more moisture, better planting depth, soil quality etc. all could be responsible for 2bu/acre) But if you see a 2bu/acre gain consistently over 500 acres then you get a much better P value. On the other hand if you see a 40bu/acre jump from product Y. you would need much less replications of it working to say that is definitely the reason I saw a gain. Ive seen universities pumping great results only to dig into the data and see a P value much lower than I would like. Also be careful of how things are worded. "proven to increase yields 10%" well they might be basing that on wheat that went from 20 to 22bu/acre and you might be thinking in your head it will take mine from 90 to 99 bu/acre. or they might say added 9 bu/acre in new study, and you might be thinking it will add 9 bu/a to 20bu wheat which would be almost 50% gain. always read as much available info and ask questions.
This being said its great to find new ideas but dont hitch your wagon to anything you dont prove to yourself on your own farm. and this is also what yield data software and soil grids etc can help you make these decisions easily and save/make you money. | |

How much do you believe the Becks PFR trials?
