title: A guide to organic grassland creator: Philipps, Lois subject: Crop health, quality, protection subject: Pasture and forage crops subject: Education, extension and communication subject: Feeding and growth description: Organic farming systems in the UK are traditionally based on ley/arable crop rotations. Up to 70% of the farmed area comprises of mixed grass and legume leys. These leys offer a powerful mechanism for supplying nitrogen through their potential to harvest biologically fixed nitrogen to support both animal production and a subsequent phase of arable cropping. This bulletin answers some of the common questions about organic grassland management. date: 2001-07 type: Journal paper type: NonPeerReviewed format: application/pdf identifier: http://orgprints.org/10812/1/A_guide_to_organic_grassland.pdf identifier: Philipps, Lois (2001) A guide to organic grassland.
