One of the most important concerns of man today is to produce enough food to feed an increasingly growing population. To do this, it needs breeders, planters and farmers who use methods that respect biodiversity. With this in mind, the United States' Union of Concerned Scientists (USC) suggests that people adopt "agroecological methods such as organic fertilizers, crop rotation, and cover crops." “Say no to plagiarism.

For this work, I will focus on these two methods: organic fertilizers, crop rotation.Organic FertilizersOrganic fertilizers mainly come from natural waste from plants or animals. They are used in background fertilization and gradually release nutrients such as nitrogen, potash or phosphorus but also trace elements essential to the good health of plants. As assimilation is slower, there is no risk of leaching. As an example of organic fertilizer, "compost and grass clippings do what fertilizers are supposed to do: they enrich garden soil with nutrients that plants and microscopic soil life forms are eager to provide." 'to use ". Crop rotation The principle of rotation is not to return to the same place of crops from the same family before four years on average, and be careful not to plant vegetables, plants or crops of the same family one after the other. same type: fruits, flowers, leaves or roots. “One system in Central Africa uses a 36-year rotation; a single crop of finger millet is produced after 35 years of growth of woody shrubs and trees being cut and burned. In the major food-producing regions of the world, various rotations of much shorter duration are widely used. “In my area, the three methods listed in the introduction might work well. But I will choose to discuss organic fertilizers. I believe that the use of organic fertilizers is consistent with environmental safety. Keep in mind: this is just a sample.

Get a personalized essay In our Cameroon, where the majority of the population still uses manual power, the use of chemical fertilizers is still widespread. Which is not only harmful to the environment but also to human health. The best alternative is therefore organic fertilizer derived from natural waste from plants or animals. What is interesting about the production of organic fertilizers is that all the inputs come from our immediate environment. Our agricultural methods are still manual, where everything is still done by human hands, the use of organic fertilizers is difficult. The labor time that can be used to make this fertilizer can be used to make other sectors profitable. some could, if necessary, devote themselves solely to the production of this fertilizer, which will require additional financial effort from farmers.
