3 Need For Sulphur in Ontario 1880's gypsum (land plaster)was commonly applied in Ont. (applied as early as 1760) About 1880 super phosphate was introduced (14 % S) After 1950 ammonium phosphate became common (very little S) Recent work is starting to show Sulphur response

30 Improved Forage Productivity with Improved Manure Use Christine Brown - OMAFRA FarmSmart Jan 20, 2018
31 Why Apply Manure to Forages? Apply P and K that crop has removed Save commercial fertilizer dollars Reduce storage requirements Spread out workload Reduce spring compaction damage Can we increase yield and/or quality?

52 Ammonia Loss Measurements Summary ~75% loss when surface applied with no rainfall Rainfall shortly after application reduces ammonia loss Partial incorporation will reduce ammonia loss (15-20%) Higher liquid content manure infiltrates more quickly; can reduce loss Uniform application probably as important as actual application rate
53 Ammonia Loss Measurements
54 Ammonia loss up to 2/3 of the ammonia-n highest in the 1st 24 hours pooled areas Rainfall after application reduces ammonia loss.
55 Manure On Forages & Johne s Disease Avoid Applying manure to: calf / heifer pastures fields harvested for dry hay, especially calf /heifer hay A field with high ph or recently limed Apply manure to fields that will be ensiled or harvested for haylage. Proper fermentation appears to kill the bacteria. Use good ensiling techniques Top dress liquid manure as soon as possible after harvest. Sunlight and desiccation kill the MAP bacteria.
56 Field Situation Animal Class Should Manure be Applied? Pastures Calves & young heifers Pastures Cows Avoid Dry hay Manure On Forages & Johne s Disease Calves & young heifers No Avoid Legume and grass silage All OK Summer annual silage All OK Summer annual green chop All Avoid Source: E. D. Thomas William H. Miner Ag Research Institute
57 Right Rate 4R s of Applying Manure to Forages Rate usually limited by Ammonium N Crop damage Goal of no more than 50 lbs/ac as ammonium-n
58 Manure Applied to Forages Ideal application rates (between 3,000 to 4,000 gal/ac liq dairy) provide in the range of lbs/acre of available N-P K 2 0 and lbs elemental Sulphur An analysis at time of application will allow nutrient crediting
59 Why Apply Manure to Forages? Apply P and K that crop has removed Save commercial fertilizer dollars Reduce storage requirements Spread out workload Reduce spring compaction damage ~ 10-15% increase yield / quality
