Speciation and bioavailability of soil nutrients: effect on crop production and environment
The agricultural production, determining the quality of the foodstuffs, depends on the biological characteristics of the crops and on the environmental properties, where soil environment plays a central role. Crops absorb water and nutritive elements from soil, but they can intake toxic elements as...
