If your soils are acidic, lime may be required before applying phosphorus. Applying phosphorus to acidic soils is likely to be a waste of money. Plants cannot grow well enough in acidic soil to use the phosphorus and they may also be limited in other nutrients as a result. Measuring acidity After following the correct procedures for soil sampling and analysis, check the pH of your soil, which will be measured in calcium chloride (CaCl2). Soil pH is a measure of the acidity (or alkalinity) of soil and is measured on a logarithmic scale from 1 (acidic) to 14 (alkaline), with 7 being neutral. Because pH is measured on a logarithmic scale, a small decrease in soil pH results in a large increase in acidity. For example, soil with a pH of 4 is 10 times more acidic than a pH of 5 and 100 times more acidic than a pH of 6. Treating acidity For acidic soils (less than 5.5 CaCl2), apply lime at 2 tonnes per hectare (t/ha) for sandy soils and 4 t/ha for loam and clay soils and reassess pH at the next soil test. Lime can take several seasons to increase the soil pH and can react more rapidly and deeply into the soil if it is incorporated, rather than left on the surface. But the extent of soil disturbance to incorporate lime needs to be weighed up against the impact on existing pasture and available feed. Soil test results should be discussed with an agronomist to ensure precise recommendations. 1 pH 2 3 4 5 6 7 8 9 10 11 12 13 14 More acid Battery acid Vinegar Ideal pH range for plant growth Car wash Caustic soda More alkaline Neutral FIGURE1.

Importance of limeBefore carrying out a phosphorus fertiliser program, it is worth testing the pH (acidity or alkalinity) of your soil.
