This paper presents the prediction of the Moorepark Grass Growth model (MGGm) in terms of grass growth and nitrogen content of the grass in a grazing context with different

This study involved the creation of a dynamic and mechanistic grass growth model (the Moorepark Grass Growth Model; hereafter referred to as MGGM) by adapting an existing grass

The adapted version of the Jouven Model can be used for grass growth simulation; however, further changes to the model could be made around the functions of the

In conclusion, short-term CA practices in the three cropping systems increased the storage of STN, SOC and labile SOC pool and enhanced soil enzyme activities in the surface soils

In this study, the soil management techniques differ essentially by soil tillage and soil cover: (1) traditional seeding on tilled soil (TS), (2) seeding on non tilled soil (NS),
