   substance is the loss of an electron or the increase of the oxidation state. When these both happen simultaneously in a reaction, it is a redox reaction. Displacement reactions occur when a more reactive halogen, like CL2, is passed into a solution of a less reactive halide ion such as KI.

   The Chemistry oh Phosphorous

   Its structure consists of 4 atoms covalently bonded in a tetrahedral arrangement4. This arrangement means the molecules are weakly bonded, so are easy to break therefore it has high reactivity. Other properties include its boiling point of 280�c and melting point of 44�c, its distinct garlic odour, and its high toxicity.

   Organic and Inorganic Fertilisers

   Slow release fertilisers are inorganic fertilisers that have been coated in a special resin so that the nutrients are slowly released over time, releasing more nutrients when the soil is warm and moist like organic fertilisers. This seems a good idea but overall costs as with all other inorganic fertilisers are higher.

   Fertiliers organ Vs inorganic

   Farmers often have problems with over fertilization when using fertilizers. With organic materials, the probability of this is far less as the concentrations of nutrients in organic materials are relatively low in comparison to inorganic fertilizers. Organic fertilizers provide a slow release of nutrients to plants, as micro-organisms need to
