Egbert, A lot of sound info, and I particularly like the ones stressing the necessity of a soil test BEFORE you spend any money on lime or fertiliser. I also like Deerherd's (#10). The link is very good info, and note the remarks about when and when not to apply the different types of fertiliser and how much. Google the phrase "soil sampling" if you have not done it before. There are some very good papers from around the US, including one from Missouri about sampling pastures.
One thing to be careful of, is recommendations for very finely ground limestone and foliar absorbed fertilisers. They are both quick fixes and not long term improvers. If you click on the "signature" below you will see a little information about them in the latest blog - about half way through. They both have their uses and I spent several hours applying foliar fertiliser yesterday. I have only used the finely ground limestone once in my life and it was to kick-start a piece of ground. Coarser ground limestone still contains a very large percentage of fines (usually more than the quantity of fines you would apply if using fines only) and this means your spreading cost is indeed spread over several years. I average spreading about two tonnes of lime a year, and put it through my fertiliser spinner. Slow, but effective and cheap to apply.
I suggest you ensure the pH is either satisfactory (anything from 6 upwards for grass) or fix it first, even if you cannot afford to fertilise for a while. The pH is the starting point for fertility building. If your soil is very alkaline I would not worry at this stage, but take local advice on it all.
