MACRO AND MICRONUTRIENTS DISTRIBUTION IN CALCARIC ALUVIOSOIL.

In times when healthy diets and personalized nutrition is one of the EU top-priority, sustainable production systems that both preserve and improve soil qualities and grant the agricultural products nutritional value, must be used at most. In this context, the content of macro and micro-elements both in soil and crop plants plays high importance and should be continuously monitored and used for the benefit of food production chains. Microbial inoculants are one of the many ways to enhance the plant's nutrient uptake capacity and increase crop yield and quality. They participate in the geochemical cycling of micronutrients and increase the available form of primary/major nutrients near plants rhizosphere. Soil organic matter also contributes to the nutrients cycle and maintains soil structure. The present study presents the soil nutrients content (N, K, Ca, Mg, Na, F, Cu, Zn, Mo, Se) in 2019, for an experimental field cultivated with organic tomatoes in Buzău county, Romania and attempts to establish some correlation between these elements. The high throughput ICP-MS analysis gives the total content of those elements, of which a part became available throughout the year and the presence and activity of soil microorganisms may accelerate this availability, which can be further exploited inside the organic or sustainable production systems by farmers.
