Somehow, I got added to the e-mail list of a fertilizer product company. Maybe it’s coincidence…maybe it’s not, but they must know my disdain for Broomsedge Bluestem, because the last few ads have been all about it!.
Some parts of the ad are sound: soil test regularly; weedy species tend to increase when soil fertility levels are outside of appropriate levels; and Broomsedge isn’t good for much. I can get on board with those.
Others…not so much, particularly when Extension/University research is shared inaccurately or out of context. Growers: buyer beware!
The ad is for liquid calcium. While I don’t have an issue with evaluating plant response to nutrients, I would also encourage you to explore validated research to support claims. This product claims to change soil pH similar to Ag Lime. According to the study below (Teutsch, Ritchey, Grove, McGrath – University of Kentucky; shared by Flanary/Schnackenberg – University of Missouri), however, the math behind the claims doesn’t compute and the results don’t suggest it works, either.
There is research from University trials referenced that deserves reading. Unfortunately, searches to find those studies have come up empty handed.
Bottom line:
- tighter margins may mean looking for something better – for less. Sometimes deals can be found. Sometimes a product is too good to be true. A little homework now may prevent a lot of headaches later…
- if you want to try a product – do it! – but limit the size and scope of the trial to limit losses. If you want to discuss a product or design an experiment, let’s chat! I’m happy to do so.
Last but not least: if THIS e-mail/blog link is becoming the clutter in your inbox these ads are to mine, let’s chat! We’ll discuss options to make it better, or I’ll get you unsubscribed if you so desire – no questions asked!
Thanks for reading! Drop me a line with your thoughts to dhallaue@ksu.edu .
