  • Calculating fertiliser, lime and gypsum rates from soil

    Lime requirements 3 Gypsum requirements 4 Fertiliser requirements For fertiliser, making the appropriate fertiliser decision requires two steps The first step is to decide how much nutrient to apply Once this has been determined, we can then look for the appropriate fertiliser to provide those nutrients Step 1: How much nutrient to apply? This depends on four critical pieces ofLime required (kg/m 3) : Net acidity = potential acidity + existing acidity* The factor 102 is used to stoichiometrically convert units of sulfuric acid (H 2 SO 4) to units of calcium carbonate (CaCO 3) A minimum safety factor of 15 should be used; The actual rate of application of neutralising materials required must be corrected for the effective neutralising value (ENV) (see SectionLime rate calculation tool Department of Water andLime required (superfine and NV>95) to lift the pH of the top 10cm of soil to 52 for a range of Cation Exchange Capacities and pH normally encountered when making liming recommendations The additional lime required to lift the pH from 52 to 55 is given in the right hand column ECEC Lime required (t/ha) to lift the pH of the top 10 cm:Planning on Liming Department of Primary Industries
