NPK Calculator,Calculate Nutrient Values of Fertilizers

This calculations can help you find out how much nutrient values of fertilizers you are applying to the turf, garden or farm. Before you apply fertilizer to them, you should have your soil tested. This will also help you determine what balance of fertilizer numbers will be appropriate for soil needs and deficiencies.Gardening resources often recommend chemical fertilizers with N-P-K ratios. Most fertilizer application rate recommendations are given in pounds needed per 1,000 square feet.

What is NPK?
A fertilizer is any material of natural or synthetic origin that is applied to soils or to plant tissues to supply one or more plant nutrients essential to the growth of plants. The three numbers on fertilizer represents the value of the three macro-nutrients used by plants. These macro-nutrients are nitrogen, phosphorus and potassium (NPK for short).
Macronutrient fertilizers are generally labeled with an NPK analysis, based on the relative content of the chemical elements nitrogen, phosphorus, potassium that are commonly used in fertilizers.
For example,the fertilizer urea is labeled 46-0-0.
