This article presents the data obtained from a field experiment in which grass–clover leys were fertilized with increasing N rates applied in either mineral N fertilizer and/or cattle slurry forms. The leys were composed of a 2–species mixture of

Purpose: Cover crops can reduce nitrogen (N) leaching, but their potential to reduce N2O emissions has been little studied, and the main traits driving the effects on both N losses remain poorly understood. Methods: We conducted a greenhouse experime

Crop mixtures are often beneficial in crop rotations to enhance resource utilization and yield stability. While targeted management, dependent on the local species composition, has the potential to increase the crop value, it comes at a higher expens

Grass-clover response to cattle slurry N-rates:Yield, clover proportion, protein concentration and estimated N2-fixation

Optimal nitrogen (N) fertilization for grass-clover leys is important, since the N application affects yields and the clover and crude protein (CP) contents of the forage. Modeling of optimal N application to maximize economic output and minimize env
