How to work out Nutrient Inputs

Liquid Fertiliser (Weight/Weight)

In order to calculate the nutrient inputs from liquid fertilisers you need to use the Specific Gravity (kg/litre) of the specific product being used. Use the following formula to calculate nutrient input: (Ltr/ha.) x Specific Gravity (SG) x (% Nutrient/100) = kg nutrient/ha. Example: For an application of 15:0:12 @ 40 Ltr/ha. (SG = 1.25kg/Ltr) convert application rate from Ltr/ha. to kg/ha. (40Ltr/ha. X 1.25 = 50kg/ha.) Multiply product rate (kg/ha.) by % N content (ie. 50 X 15% = 7.5kg/ha.) Multiply product rate (kg/ha.) by % K content (ie. 50 X 12% = 6.0kg/ha.)

Super Turf Solutions Liquids

Liquid Fertiliser (Weight/Volume)

Use the following formula to calculate nutrient input: Nutrient content / 100 x Application rate = kg nutrient/ha. Example: An application of a Liquid (w/v) High N (33-0-0) at 80L/ha would deliver…. Nutrient content / 100 x Application rate = kg nutrient/ha. (33/100) x 80 = 26.4 kg/ha N applied
