What's everyone's preference and reasoning for?
Liquid.
I can ring a contractor for them to bring fert with them and apply, no bags, no infrastructure, no hassle. Just leave sprayer man a map.
They just bring a loaded bowser with them and leave at the yard, will swap it at lunchtime or so if one bowser isn't enough. It's the easiest way I can think of to get the fert out.How well does that work Dan? Do they just get a tanker to turn up and load from it?
Planning on that how do you melt it down ?Solid but make liquid urea for outer headlands
Add urea to water in some form of open top tank and agitate continuously. It’s an endothermic reaction so it needs lots of heat from the surroundings to complete, to the point that the tank will form a frost rhind in anything less than 15 degrees air temperature. Typically it will take 12 hours for the rhind to melt at which point you’ll know the reaction is complete, but have a poke on the bottom of the tank with a stick to make sure. Good agitation is key, so use a 2” pacer / 330L/m pump or larger, with Venturi type jets. The warmer the ambient temperature the faster it will complete. At 5 Celsius it takes an age, above ten a lot better, above 15C is ideal.Planning on that how do you melt it down ?
Same as when you are spraying them.When applying liquid fert, what do you do when you come to electr
When applying liquid fert, what do you do when you come to electric poles in fields?
We have our old 3000 litre bulk tank was thinking of using that, fill with the required amount of water turn on the agitators and have a bin above with a slide on to slowly let the fert inAdd urea to water in some form of open top tank and agitate continuously.
