It is key when you are buying your
fertiliser that you actually think about the time that you are going to spread it, make sure you think about sulfur and P&K at the time, not just straight nitrogen. Once you have set up your spreader, on the actual day you need to take into account various other things such as the weather, the bout width, the
forward speed and the headlands. When you are thinking about the weather, wind is a big factor. You do not want it to be too windy because this will affect your spread pattern. As a rule if it is too windy to spray
something then we will suggest that you do not spread either. There is two components to forward speed, not only will you affect the rate if you have the incorrect speed, but you will also affect the spread
pattern itself, that is why it’s key to make sure that you get that forward speed correct. With your spreader you should have either a headland disc or a border device that enables you to spread correctly at the
headlands because that will then stop over or under fertilisation of those
areas. Over fertilisation is a problem because a) You are going to be throwing your money away but b) You could be putting on too much nitrogen on the
crop which could cause lodging and then you will have issues at harvest time. On the other hand, if you are under fertilising a crop then you are not getting the potential out of it and there could be loss of yields there. The good news is getting all these things right is not that hard as long as you
got a good setup, which means that you are going to spread the fertiliser correctly
