Approaches to new technologies in the field of agriculture (technologies proposed by specialists in the field) in order to protect plants, increase productivity, greening the soil and reduce the impact of pollution of agricultural ecosystems are green, non-polluting technologies to be implemented by farmers to reduce costs in agriculture. polishing, obtaining healthy, ecological products and supporting the restoration of processes carried out in the soil, increasing beneficial microbial populations, all in order to achieve an intensive system of sustainable agriculture. Excessive use of fertilization and plant protection products in agriculture has led to the emergence of soil acidification, a phenomenon that has accentuated forms of damage to soil, plants, agricultural products, beneficial soil fauna but especially with negative effects on man and animals. Excessive fertilization and application of PPP products without respecting the indicated doses have irreversible effects on the environment. Soil acidification is a big problem for farmers. The fact that the areas affected by this phenomenon are expanding from year to year detonates "a minus" for current systems and technologies in the agricultural field of our country. The use of alternative fertilization and plant protection technologies such as natural composts, seaweed, as well as the use of microorganisms -bacterial biopreparations- will lead to the occurrence of agricultural ecosystems, to soil recolonization (useful and beneficial fauna restoration soil) but especially an increase in the level of organic elements and microelements in the soil, the solubilization of insoluble compounds in order to provide plants with the mineral elements necessary for their growth and development and, implicitly, agricultural production and obtaining much healthier products for humans and animals. This paper aims to present the main advantages of using bacterial biopreparations, both economically and in terms of crop productivity, aspects related to plant biometrics but especially the benefits that these bacterial cultures have on agricultural ecosystems, namely soil, plants, environment, man and animals.
