[QUOTE="Brisel, post: 1817360, member: 166"] I use Hypro ESI nozzles too but they do cause scorch so I will switch to dribble bars next year, with short pipe extensions to go onto the nozzle holders. My single spray lines are too low for the dribble bars to hang without risking them catching the ground or crop hence why I want to fit them permanently inside the boom frame with the short pipes. A cheaper option than twin lines is a secondary nozzle body for the dribble bars using a single line. I'm sure [USER=1832]@SimpersTradeCounter[/USER] or [USER=821]@JRA[/USER] can post pictures. I use Nuram 37 which is diluted UAN. It can be very scorchy but kinder urea solutions are a maximum of 20% N so for 100 kg/ha N in one dose you are looking at 500 l/ha. With N37 the same dose is 270 l/ha which makes a big difference to work rate. I'm running 80 - 330 l/ha with most doses over 250 l/ha so that's a lot of filling time. There are a few users in here who melt their own solid but that makes a lot of extra work though it can be done over winter & it best if you have good tank capacity & a source of cheaper distressed fertiliser. I rent tanks from Yara for £200/tank/year though I'm supposed to buy my liquid from them. In reaity they will match the price of Bunns/BFS/Omex so the market is quite competitive now.
