Organic And Synthetic Fertilisers
Many people would ask what the difference is between organic and synthetic fertilisers. As the name suggests, organic fertilisers are much more environmentally friendly than synthetic fertilisers. This is because organic fertilisers are materials derived from vegetable matter, animal matter, animal excreta and human excreta. Examples include worm castings, seaweed, guano, manure, composite and blood meal.
Synthetic fertilizers on the other hand, are all man-made inorganic compounds. Usually derived from by-products of the petroleum industry. Examples include ammonium nitrate, ammonium phosphate, superphosphate and potassium sulphate.
