Fertilizers:what are they and how are they applied?
As we know, for almost two decades the world population has been increasing, which entails a need to increase food production. To increase this production, the plants extract a greater amount of nutrients from the soil, which, since they are not returned, generate a gradual impoverishment of the soil.
Afertilizer It is any substance, simple or compound, or a mixture of both that contains essential nutrients for the development of plant organisms. They return nutrients to the soil that are extracted by plants, or that are lost through erosion processes.
It is not possible to estimate the contribution of fertilizer use to the increase in agricultural production, since there are other decisive factors. Anyway, fertilizers will be a decisive tool in production beyond the development of new technologies that have emerged.
Plant organisms require nutrients for their growth. There are 16 essential elements, which are obtained by plants from different sources.
From the air, they obtain carbon dioxide (COtwo). From water, hydrogen and oxygen in the form of water (HtwoEITHER). Soil and fertilizers provide plant organisms with the vast majority of the nutrients they need, in the form of macro and micro nutrients. They are Nitrogen (N), Phosphorus (P), Potassium (K), Magnesium (Mg), Sulfur (S), Calcium (Ca), Manganese (Mn), Iron (Fe), Chlorine (Cl), Molybdenum ( Mo), Zinc (Zn), Copper (Cu) and Boron (B).
If there is no nutrient limitation, crops may have higher yields. If a single nutrient required by plants is scarce, crop yields will decrease (Law of the minimum). Therefore, in order to reach the potential yield of crops, the application of fertilizers is necessary.
There are different ways of fertilization. , being chemistry the most widely used worldwide. Fertilizers can be classified according to different criteria:
In order to be efficient and for the plants to use all the nutrients provided, and in this way also to minimize pollution, the farmer must choose the amount, the right time and the method of application of the fertilizer. The most used methods are:
Before selecting the type of fertilizer to use and the method of application, the nutritional requirements of the crop and the level of fertilization necessary must be known. For that, there are several tools available such as:
Advice of Commercial Mida
In times when agricultural margins are reduced, to avoid unnecessary expenses, the nutritional needs of the crop to be planted must be known. In addition, it is recommended to carry out soil and/or plant analysis to calculate the fertilization needs of the implanted crop. Finally, it is important to fertilize at the optimal times and always be respectful of the environment.
