Fertilisers

Since the early development of agricultural practices, people have always sought different ways to increase their crop yield. Notable are the use of organic and inorganic fertilizers, insecticides, fungicides, herbicides and improved cultivars. The early use of pesticides included a variety of substances such as urine, lime-soap suds, vinegar, tobacco, and similar simple compounds. In the modern days, many farmers like to use chemical fertilisers but due to the increased using of chemical fertilisers has negative thus I choose to use organic fertilisers.
