For the last 10 or so years, we've used an Andrew Guest Accord hopper to place DAP on our potato planter, reasonably successfully.
It's not without flaws though, there is a limit to how fast we can plant, and how much fert we can meter out without the thing jamming/wheel skipping/backpressure becoming a problem.
We have to completely rebuild the metering unit every year - not a cheap job - and would like to upgrade it really, if not this season, then next, when we plan to upgrade the planter.
An obvious option is liquid, and we have a front tank unit that I bought from a friend, in anticipation of such a change, but is it the right way to go? Logistics being the major drawback - we currently have a couple of decent water bowsers that we could use for fert, but have neither a storage tower, or a suitable site for one. In field, obviously one of the bowsers could supply the fert, the other one being retained to feed the potato washer, but that's more hassle than popping 3 bags of DAP on each seed trailer.
Which leads me towards considering replacing the Accord hopper with a better alternative - the obvious being a Horstine Airstream - seem well built, but expensive. What are they like to live with? Operate? Keep clean? Wear rates? Any problems when they get a few years down the line?
If I remember correctly Alpego make one, as do Horsch, and doubtless others.
Any suggestions/experiences?
Cheers
