Relationship between soil fertility and pasture composition on milk quality in Simmental-Fleckvieh production systems in the Peruvian Amazon

This study aims to identify the relationship between soil fertility and pasture composition on milk quality in ten Simmental-Fleckvieh cattle production systems across four provinces in the Peruvian Amazon: Chachapoyas (system I), Bongara (system II), Rodriguez de Mendoza (system III), and Utcubamba (system IV). While no significant differences were noted in pasture composition, milk, and soil parameters such as pH, electrical conductivity, phosphorus, and potassium among systems, significant statistical differences were observed in soil carbon, organic matter, and nitrogen content (p
