Industries 2) Read the following para on Fertiliser Problems and comment on it. Manure and compost contain humus and living organisms that slowly release minerals as they decompose. Chemical fertilizers provide minerals (usually nitrogen, phosphorus and potassium) which dissolve in water and are immediately available to plants, but may not be retained in the soil for long. They may be leached from the soil and pollute groundwater, rivers, and lakes, Chemical fertilizers (as well as pesticides) can also kill bacteria and other organisms in the soil. This means that after some time of repeated use, the soil will be less fertile than ever before. Without micro-organisms, the soil will be dependent on frequent addition of more and more chemical fertilizers. The variety of nutrients which are normally produced by micro-organisms may also be reduced.
