Since our main crop is grass, and it's important to us to get it right, we decided to have our soil tested. As well as pH, the test looks at levels of macro nutrients like potassium and phosphorus and levels of micro nutrients like calcium, magnesium, zinc and iron. The nutrients in the grass are inflluenced by the nutrient status of the soil, and the various elements interact with each other as well. For example, high levels of zinc can interfere with the availability of iron.
Across our ten acres, we had five samples taken and they are all different. Only Sheepfold needs lime while the other areas have a high pH, which should decrease over time simply by grazing with livestock. Across all the areas tested, some key elements are low - calcium, sulphur, sodium (odd since we're so near the sea?).
