Question

what are tha qualities of a good fertiliser?

Answer 1

Answer:

Fertilizer is a special material such as manure or chemical mixture which is used to make the soil more fertile and to provide the required nutrients for the healthy development of plants or crops. Every farmer uses fertilizer to help their crops or gardens to grow well.

Some common types of fertilizers are: urea, diammonium phosphate, ammonium chloride, calcium, NPK etc.

A good fertilizer should have the following qualities to promote the healthy growth of crops:

• Provide essential nutrients to the crops: Crops require food to grow and these good quality fertilizers provides nutrients to them. A class of fertilizers called micro nutrient fertilizers is engineered to enrich crops with vital nutrients that help support human health. For example, micro nutrients such as zinc are important to human nutrition, especially children. The pH level of the soil should be monitored throughout the cultivation.

• Develops tolerance against harmful factors in crops: Addition of fertilizers to the soil or water, helps crops to develop tolerance against harmful factors like pests, weeds, insects and diseases, thereby reducing the need for herbicides and pesticides, thus producing healthier crops.  

• Increases water retention capacity in crops: An effective fertilizer helps plants to increase their water retention capacity and improve the depth of the roots, which helps during the days of water shortage. Potassium found in fertilizers increases the strength of the stalks and straws of plants.

• Growth Booster for Plants: Nitrogen containing fertilizers acts as a growth booster, as nitrogen is the most essential element in the growth of plants. Phosphorus containing fertilizers helps in the faster development of seeds and roots.

• Removal of excess water from the soil: The fertilizers also avoid the water retention feature of the soil as they contain absorbent organic materials like perlite, coco fiber, worm castings .
