Organic fertilizers should be made of natural decomposition, because these materials are easier for the plant to digest. As you will see from the list below, organic fertilizers are simple and natural ingredients. However, they contain essential macro- and micronutrients such as nitrogen, calcium, phosphorus, potassium, magnesium, iron, organic matter and trace minerals.
Here are some organic fertilizers that you might want to try: alfalfa meal, bat and bird guano, bloodmeal, bonemeal, chicken manure, cottonseed meal, Epsom salts, feather meal, fish emulsion, fish meal, greensand, humic acids, kelp meal, oyster shells, seaweed (liquid), soft Rock Phosphate and worm castings/Vermicompost.
When you’re reading the labels on fertilizers, look for the basic elements that you learned from the periodic table. For example, avoid super triple phosphate, because this is a manmade form of phosphorous. If you’re not sure where to start, begin with the basics. Liquid seaweed is a supplement that provides trace elements. Also, adding humic acid can improve the soil health.
