Pasture fertilty should be maintained through the use of soil tests. The first fertilizer should be added after the first grazing as this can help to prevent problems from grass tetany. Lime is very important to maintain correct soil pH. Soils that are too acidic (pH is under 6.0) will tie up nutrients and thus nutrients will not be available for plant growth. One way to save on the cost of nitrogen for fertilizing pastures is to include a legume in the mix. If about 30% of the pasture mix is a legume, this should produce enough nitrogen to feed the grasses.
