Fertilizers


Organic fertilizer refers to the fertilizer, resulting from organic nature, such as manure or peat. Organic fertilizer can also be a man-made . Organic fertilizers are carbon-based compounds that increase the productivity of plants and has many benefits that chemical fertilizers do not offer. Organic fertilizers   help improve soil with the addition of essential nutrients for plants, which is the key to successful organic gardening. Without fertile soil and nutrients  plants can not flourish. The main advantage of synthetic chemical fertilizers is that they provide more nutrients than  organic fertilizer can do, but this can sometimes cause plants to dry up due to excessive use of  fertilizers. Another draw back is that of artificial fertilizers can contaminate soil and water which in turn contaminates our  food. On the other hand  organic fertilizer made from natural materials  is safe for you and the environment.
Organic fertilizers also differs from chemical fertilizers in a  way to feed their plants and build  soil. Soils containing a large amount of organic matter remain loose and airy and contain more moisture and nutrients. This helps promote the growth of soil organisms and promote the healthy development of plant roots. The only use of chemical fertilizers, soil loses its organic matter and the  microbial activity . As organic matter is used by plants, soil structure deteriorates, becoming compact, lifeless and less able to retain water and nutrients.  Organic fertilizer is usually made mostly of water-insoluble organic materials which decompose and release nutrients slowly. Organic fertilizers can be more expensive than chemical fertilizers, but they offer more benefits and you can even make your own organic fertilizers with a home compost. Organic fertilizers usually takes longer as well, because they are mostly insoluble in water, tend to stay where they are used and helps keep moisture in the soil and break the hard ground. Good soil enriched with organic fertilizers is essential to prevent many plant diseases,  that can affect your garden. Some disease organisms living in soil, but can be killed by adding compost or manure. Organic compost heats up dramatically  and is naturally free of most soil diseases .
