Discussion open for comments on @EgUsphere: Previous integrated or organic farming affects productivity and ecosystem N balance rather than fertilizer 15N allocation to plants and soil, leaching, or gaseous emissions (NH3, N2O, and N2) doi.org/10.5194/egusph…

EGU_BioGeo's tweet card. Abstract. Legumes in crop rotations are considered an ecological intensification management practice to reduce nitrogen (N) losses to the environment. However, studies on N allocation and loss on...
