What are the types of Chemical Fertilizers
Types of Chemical Fertilizers
There are two types of fertilizers:
The decaying animals refuse and excreta along with rotten leaves and fruits form useful humus. This humus when mixed with soil, it increases the fertility of soil. This type of fertilizer is called organic fertilizers.
These fertilizers are used to replace mineral ions for better production of crops. Usually three chemicals are added for the purpose. These are nitrogen, phosphorus and potassium. These artificially fertilizers are called inorganic fertilizers.
Hazards of Using Chemical Fertilizers:
- i) Continuous usage of chemical fertilizers causes loss of organic fertilizers in soil.
- ii) Unabsorbed nitrates are carried by rainwater into the rivers and sea, which harm the aquatic life.
iii) The top layer of soil damaged due to continuous usage of these fertilizers.
- i) These problems can be reduced by using that chemical which are less soluble and slowly release nitrogen into soil.
- ii) Use of organic fertilizers should be increased to avoid these problems.
Note: Correspondents are very difficult to break away from work, family, hobbies. There are constant calls that distract. Thoughts return to the abandoned projects. Prior to studying, if at home children without supervision or at work the report should be done? And if the group has a good relationship (although it is often difficult – all too different people and meet for a short time), then it takes time and communication with classmates, it does not do without gatherings … Studies become a burden. From this it follows that the quality of such training leaves much to be desired. If the potential employer was delighted to hear the name of the university, then, most likely, will be disappointed to learn about the correspondence form. Do not paint and the confidence that all the control, which extramural students must do in large numbers between sessions, just downloaded from the Internet . Sometimes it happens, because a person lives his life – many cares. Control everything is delayed for tomorrow. And we have to do something when the session has already come. And this training breeds cunning people who are shirking work, they say, studying, and in the university complain about the workload.
