You really don't have a fucking clue. The initial application of fertiliser is no larger than subsequent ones for the simple reason that crops use the stuff at a steady rate. For instance, for each ton of wheat we need the following in kilograms: 22.0 Nitrogen 3.8 Phosphorus 4.7 Potassium 2.2 Sulphur 0.4 Calcium 1.6 Magnesium. That is each and every year. If you use more at the outset than later on, it either means that you have used more than you needed to at the beginning or you are not using enough subsequently to bring your crops to maturity and harvest.mistermack wrote:Only for the first year. Once that's done, it just needs a tiny top-up every year, if that.
Australian farmers use over 4 million tons of fertiliser annually. Much of that is already imported, and there is pressure within nations we import from to stop exporting their stuff. Whoever said earlier in this thread that Australia could easily support several hundred million inhabitants has no fucking idea what he is talking about. I think we'd be struggling to support 50 million by the end of this century, and that number will be reached without increasing immigration.
Finally, will you, BG and D-K poster boy please stop pulling opinions out of your arses? It's getting a tad tedious.
