So many fertilizers to choose from - which ones are required for plant growth, how much to use and what amendments will help to improve soils
Organic fertilizers are a good source of slow-release nutrients and organic matter When you apply an organic fertilizer like bloodmeal, cottonseed meal or seaweed extract, you are applying plant nutrients plus organic matter which is composed of carbon - the basis of all life. The concentration of nutrients in organic fertilizers is relatively low compared to synthetic type fertilizers, but the delievery of these nutrients to the plant is at a pace where they can be adsorbed in a more efficient manner - therefore, less waste. One of the primary benefits, however is with the application of the organic matter fraction of the fertilizer. The benefits of adding organic matter are many including increasing porosity, clodding/soil tilty, drainage, buffering soil temperature, holding soil moisture, reducing compaction etc. You garden soil should be at least 2 to 5% organic matter but no greater than 20%.
