“Types of Organic Fertilizers“. Types of Organic Fertilizers are different types of fertilizers derived from vegetable matter, compost, manure, animal matter etc. On the other hand majority of chemical fertilizer are extracted from minerals or produced industrially. Naturally occurring Types of Organic Fertilizers include animal waste, peat, manure, slurry and guano.
In the nature, usually plants don’t needed to be supplied by Types of Organic Fertilizers by a farmer or gardener, as microbes present in the soil break down organic matter ( dead plant leaves, animals and insects) which over time become nutrients for the soil. These Types of Organic Fertilizers becomes available for uptake by the plants root. Other Types of Organic Fertilizers are derived from rocks, which releases minerals into the soil as they erode over time.
Organic agriculture and gardening also rely on Types of Organic Fertilizers and gardening principles. Soil testing reveals what kind of nutrients are already present in the soil which helps you to decide how much and what kind of fertilizers to use.
The best known types of natural Types of Organic Fertilizers are
Other Types of Organic Fertilizers include Seaweed, grass clippings and commercially packaged organic fertilizer sold at nurseries and garden supply stores. Ashes from stoves or fireplace, cold coffee and other kitchen waste.
Types of Organic Fertilizers – Animal-Based Fertilizers
Many Types of Organic Fertilizers comes from animal sources, either as slaughter byproducts or livestock manures. For example Blood, feather and fish meals serve as sources of natural Nitrogen. On the other side, Blood meal provides the highest Nitrogen level at 12% among different Types of Organic Fertilizers. Bone meal contains 12 percent phosphorus. Animal excreta also enrich the soil with nutrients, including Nitrogen, Phosphorus and Potassium. However, it may be noted use of raw manure as Types of Organic Fertilizers can damage plant roots, lower pH, pollute surface and ground water.
Types of Organic Fertilizers – Plant-Based fertilizers
Alfalfa and Spybean meals contain 4 – 7 % Nitrogen. Cottonseed meal also contains about 7 % Nitrogen; however, over use of chemical pesticides on cotton crops generally makes cottonseed meal unfit for use in organic production. Wood ash also provide a low amount of Nitrogen and contains about 6 % Potassium, however, excessive use of wood ash can raise the soil pH.
Types of Organic Fertilizers – Mineral fertilizers
Colloidal and rock phosphate are Organic Fertilizers that add Phosphorus to the soil. However, soil conditions can greatly affect the effectiveness of these products; a soil test can decide the product that is best for your circumstances. Two conventional Types of Organic Fertilizers are natural potassium sulfate and potassium magnesium sulfate. Green sand is organic source of potassium which has about 7% Potassium.
