using liquid has its problems the specific weight varies depending on product and temperature this leads to inaccurate reading through most sprayer flow metres they need calibrateing for each product
some rate controllers are also quite slow at varying the rate with speed changes and when sections are shut
I have found the amazone spread pattern trays to be quite accurate as long as I do every product every year
on balance there is not much between solid or liquid but the liquid costs considerably more
how accurate do we need to be when the optimum rate on wheat varies by 50 kg of n or more from year to year and we only know after the event what was the optimum and if you over do it in wheat the extra is used by the following rape crop
