What is organic fertilizer?

Organic fertilizer is a kind of compost made from organic sources, so it can be used for organic planting safely People with organic gardens can make their own organic fertilizers, and they can also buy them in garden shops But commercial organic fertilizer is more expensive than traditional compost because it requires more work, including verifying that all materials are really organic There are different definitions of "organic" around the world In general, organic agriculture does not use chemicals to control pests or fertilize, and advocates the use of natural fertilizers, natural methods to control pests, and other traditional agricultural technologies In order to obtain organic certification, the product must be sent to the relevant government agencies for inspection In addition, things used in the production of organic products must also be certified organically to avoid cross contamination The raw materials of organic fertilizer are all from organic sources In organic agriculture, cuttings and other wastes are often used to produce organic compost In addition, straw and coffee grounds for composting also need to be obtained from organic sources Unlike traditional composting, organic manure should not contain chemical residues and other non organic materials as defined by law For organic planters, the use of organic fertilizer must avoid the introduction of substances that will endanger the organic qualification of plants For example, composting of sprayed processed fruit will pollute organic soil and thus lose the organic qualification of plantations Since organic qualification is difficult to obtain, the organic fertilizer uses strict procedures to confirm that the product is organic In large organic farms, the surrounding composting cooperatives can be used as a stable source of organic fertilizer In addition, farms that do not want to involve themselves in composting production can also purchase commercial compost.
