Resumen:
Zinc (Zn) deficiencies occur all over the world. Due to the naturally high soil fertility of the Pampas region, Argentina, macro and micronutrients have not been applied to soils through fertilization in a massive way. As a consequence, some trace elements deficiencies were noticed in some forage crops during the last years as a result of nutrient depletion. Trace mineral deficiencies were detected in dairy cows, causing a variety of suboptimal performances such as poor production and reproductive inefficiencies. Zinc and copper are the trace elements present in largest amounts in Buenos Aires City´s biosolids. Soils amended with biosolids were reported to have high Zn availability. Therefore, biosolids land application may raise the concentration of Zn in forage crops, reducing the need for mineral fertilisers or supplements in the diet of dairy farms. This chapter address sound soil and crop management practices that may not only enhance crop productivity but also help in reducing Zn deficiencies in dairy cattle.
