What is Compost Manure Calculator

Compost manure calculator is a tool used to determine the amount of compost needed for a specific area of land, based on various factors such as the type of crops being grown, soil type, and the desired nutrient content of the soil.

The calculation involves determining the nitrogen, phosphorus, and potassium (NPK) content of the compost, as well as the target NPK content for the soil.

The difference between the two is then used to determine how much compost is needed to reach the target nutrient levels.

Compost Manure Calculation Formula

Here is a general formula that can be used to calculate the amount of compost needed:

Compost required (in pounds) = (Target NPK – Current NPK) x Area of land (in square feet) / Compost NPK
