Difference between uses of manure and fertilizer |

FERTILIZER: 1.fertilisers are inorganic chemical substance. 2. Fertilisers do not contain organic matter. 3. Theyou are prepared in factories. 4. Fertilisers contains much higher quantities of nutrients. 5. Water pollution occurs. Manure and fertilizers are useful for the crop but differently:A manure is not rich in essential plant nutrients like Nirogen, Phosphorus and Potassium but fertilizers provide these essential nutrients.So we can say fertilizers are nutrient specific.\xa0A manure provides lots of organic matter like humus to the soil , whereas , a fertiliser does not provide any humus to the soil. So manure increases the binding capacity of the soil.A manure is absorbed slowly by the plants because it is not much soluble in water , whereas , being soluble in water , a fertiliser is readily absorbed by the plants .\xa0So the soluble nature of the fertilizers make them more useful. |

Answer» The main answer is that cotton is a fibre which absorbs sweat better than all fibre means it is best absorber of water and when it becomes wet, it sticks with skin and the environment of outside evaporate the sweat of the surface of cloth. When the sweat evaporates it sucks the heat from our body and makes us cool. Due to the feeling of coldness people wear the cotton cloths. Cotton is a natural fibre.It notonly absorbs sweat during summer season but is also a skin friendly fibre. Because cotton is a good absorber of water. It absorbs sweat and helps in evaporation which makes our body cool We are wear clothes to protect our bodies from sunlight, dust,rain etc Cotton clothes replace the air |
