Abstract

Biofertilizer is the liquid effluent obtained from aerobic or anaerobic decomposition of organic matter in the presence of water, or to be more specific, it is the remaining matter left from the decomposition of organic compounds containing both single celled or multi cellular organisms (bacteria, yeasts, filamentous fungi and algae) and the metabolites they generate. Some of the statistics relating to Brazil’s increasing dependence on the use of pesticides in agriculture are quite concerning. For example, in the last 15 years, within the state of Ceará, incidences of rare types of cancer arose to 38% above the national average. Likewise, the sale of agrochemicals in Brazil grew 190% over the last 10 years, which is more than twice the world average. Of the 50 most commonly used pesticides in the Brazil, 15 of them are actually banned in Europe. According to the last Brazilian Health Regulatory Agency (Anvisa) survey, agrochemicals have been found in 67% of the foods analyzed (25% of which were banned). In view of this alarming reality, a change of attitude is not just necessary, it is mandatory. We need to change our philosophy regarding agricultural management on a national level, one that promotes viable agricultural methodologies to produce crops and livestock, which result in a more healthful humanity and a balanced, sustainable environment.
