## What is A manure nutrient calculator?

Manure nutrient refers to the plant-available nutrients found in animal manure, such as nitrogen (N), phosphorus (P), and potassium (K).

These nutrients are essential for plant growth and development, and applying manure to croplands can help to replenish soil nutrients and improve soil health.

The nutrient content of manure can vary depending on the type of animal producing the manure, the animal’s diet, and the management practices used in the production of the manure.

## Manure nutrient calculation Formula

To calculate the nutrient content of manure, the following steps can be used:

1. Determine the dry matter content: This is the amount of manure that remains after all the moisture has been removed. The dry matter content is calculated as a percentage of the total weight of the manure.
2. Determine the nutrient content on a dry matter basis: The concentration of each nutrient in the manure is determined, and the values are reported on a dry matter basis, meaning they are expressed as a percentage of the dry matter weight.
3. Calculate the amount of each nutrient in the manure: The nutrient content of the manure is then calculated by multiplying the dry matter content by the nutrient content on a dry matter basis.

For example, if the dry matter content of a manure sample is 25% and the nitrogen content on a dry matter basis is 1.5%, then the total nitrogen content of the manure would be:

(25% x 1.5%) = 0.375% nitrogen

Note: These calculations can be complex, and laboratory analysis is required to obtain accurate nutrient content values. Manure nutrient content can also vary widely from year to year, so it’s essential to obtain a fresh sample for analysis.
