Effect of replacing conventional Italian ryegrass by organic nitrogen source systems on chemical soil properties

Aim of study: To evaluate agronomic performance and changes on soil chemical properties in two types managements: conventional or sustainable.Area Principality Asturias, Spain.Material methods: On a sandy-clay-loam texture soil, three winter forage legumes (faba bean, red clover white lupin), monoculture mixed with Italian ryegrass organic fertilization (sustainable management) versus inorganic (conventional were evaluated during consecutive years. After the harvest spring, rotations completed maize crop purpose to effect sustainable management yield parameters.Main results: The results showed that faba bean had better edaphic quality than monoculture, lupin ryegrass. Faba ryegrass, both fertilization, could be competitive crops since yields comparable fertilization.Research highlights: Current agricultural practice changed for more system, including legume crops.
