Organic fertilizer contains humus or plant materials that decompose gradually, releasing nutrients into the soil that plants need to grow. Specifically, organic fertilizer contains the three main nutrients that plants require: nitrogen, phosphorous and potassium, plus other secondary nutrients and minerals. The most well-balanced organic fertilizer and most commonly used, is compost, which nourishes plants and acts as a soil enhancer.
