Other organic manures	Dry matter content and total phosphorus content to be declared in accordance with the Waste Management Licencing Regulations (Northern Ireland) 2003 . 60% phosphate availability assumed at soil phosphorus index or 0 or 11, 100% phosphate availability assumed at soil phosphorus index greater than 1. For anaerobic digestate the record of nutrient content analysis as required by regulation 12(1) shall be used.		
Chemical fertilisers	Dry matter content and total phosphorus content as certified by the producer. Phosphate availability assumed to be 100% for all soil phosphate indices.		
1 For potatoes and vegetable crops, these availabilities should be used regardless of soil phosphorus index.			
250% of phosphate availability assumed at soil phosphorus index of 0 or 1 and for potatoes and vegetables.
