Fertilizers are usually Nitrates, phosphates or a combination of both.
These compounds are applied to the soil, they go down in the soil and are taken up by the plants root structure, and then moved in the transpiration stream up to the leaf and used in the leaf for the construction of proteins (nitrates) and phosphates (DNA and membrane structure).
Fertilizers can be divided into two groups:
1.Organic: produced from animal waste on farms, then collected by the farmer (usually after decomposition and fermentation) and forms a compound known as slurry which is applied to the fields, giving the plant a supply of nitrate and phosphate to promote growth.
2. Artificial: Chemical which are synthetically produced e.g. potassium nitrate and amonium nitrate, bought by the farmer and applied to the field which will go into a solution which will release the nitrates and phosphates which promotes growth.
Possibly causes Eutrophication which is a problem which arises from fertilizers.
