How to Compare Manure Fertilizers


Manure, in general, makes an excellent fertilizer for almost any yard or garden situation, but the fact is, not all manure is created equal. Some manures have a higher concentration of nitrogen, others a higher percentage of phosphorous while others might have more potassium. Selecting the right one for your needs depends on what you are fertilizing and the condition of your soil to begin with.

Step 1

Decide what plants you need to fertilize and the age of the plants. Sprouts generally do not benefit from a fertilizer too high in nitrogen, which can cause unrestricted growth and spindly plants.

Step 2

Test your soil to determine what (if any) nutrients it is lacking. People at a nursery will be able to tell you where your soil can be tested--the cost is usually minimal.

Step 3

Read the labels on several different types of manure fertilizer to find the one with the best balance of nitrogen, potassium and phosphorous for your needs based on your soil test results and consultation with a nursery over the nutrients which would be best for your particular fertilizing needs.

Step 4

Follow the manufacturer's recommendations or your nursery's recommendations as to the amount of manure that you should apply. The amount of manure you should apply will vary based on the condition of your soil and the type and age of the plants you are fertilizing.
