Liquid fertiliser

[cb387]

How easy is it to dissolve solid fert such as DAP to liquid? Would like to use it at drilling but don’t have a huge acreage to do so deliveries of liquid probably uneconomic. Being able to make our own a few days ahead would be ideal.

Could it be done in IBCs with some agitation, or would it need heating?
Are there any other pitfalls such as sediment needing to be filtered out?

DAP is hard (as is anything with P or K ) straight N or N and S products are easy enough though

Dont bother, it will be difficult to dissolve properly leading to filtration issues with your sprayer.Tried it once,never again....
I would recommend use of a microgranular DAP available through Frontier.We used to put it on at drilling with a Techneat Microcast applicator very easily.

I am led to believe that MAP is more soluble, just harder to buy.

I buy liquid fert in IBCs for using on my drill isnt overly expensive in my opinion. yara and omex both sell it this way.

Thankyou all for the info

Hi there,

Half thinking about liquid N on WOSR. It’s just starting to flower and looks a good crop.

I usually put on 30-35kg of N in granulated form at this point.
A couple of local suppliers have started selling liquid N.
I would have to buy nozzles but it should be more accurate and have better uptake than granulated (forecast looks very dry).

Any opinions as whether it’s agood idea?

Any nozzle recommendations?

Tia.

Hypro ESI nozzles, far better than Agroco umbrella’s. I know 3 of us had agroco’s over 5 machines and all had scorching problems plus they didn’t Turn easily in some parts of some boom’s, hypro ESI are nice and small and no scorch.

Dribble bars are best but I got on well with Hardi Quintastreams. Get a size that keeps you under 4 bar, ideally 2 bar. Dilute it if you can as it will scorch yield building leaves.

As you can probably tell by the machinery, a year of two ago (?) we did liquid ear wash on our milling wheats and dissolved urea to make our own. We did experiment with DAP and as we expected it took a looooong time. Had a diesel driven pump circulating the liquid in the tank. Once all dissolved would then transfer into the tank next to it for sprayer. I remember the outside if the tanks freezing as it dissolved (takes energy, in this case heat energy to change state). Was a big cost saving in those days and stuff was bought for very little.
