2	Nutrient flows from agriculture
3	Components in manure
4	Water Spilt water Dishwater Cleaning water Precipitation - evaporation Litter Bedding material Feed residuals
5	Factors influencing the distribution of components in manure
6	Chemical composition of Solid and Semi-solid manure
7	Chemical composition of slurry
8	Availability and loss of N for manure from milking cows
9	Aspects on manure handling systems
10	Basic rules for planning manure handling systems Analyse and discuss the situation on each farm in order to select a suitable manure handling system which: Optimises utilisation of nutrients Supports good animal welfare to achieve high production Create good and safe working conditions
11	Basic rules for planning manure handling systems, cont. The most suitable manure handling system for an individual farm could not be selected without taking into account: All other handling chains on the farm The farmer’s knowledge and future plans The farmer’s economic situation
12	Important parameters for planning of manure handling systems Selection of handling system depends on the farmers knowledge, interests and planning horizon

21	Manure Spreading
22	Spreading precision, application rate, longitudinal and transversal
23	Factors causing ammonia emissions
24	Rear discharge, one-step spreader, vertical beaters
25	Rear discharge, one-step spreader, horizontal beaters
26	Rear discharge, one-step spreader, horizontal beaters
27	Rear discharge, two-step spreader, horizontal beaters + spreading discs
28	Rear discharge, two-step spreader, longitudinal augers + spreading discs, especially for semi-solid manure
29	Slurry spreader with splash plate
30	Slurry spreader with trailing hoses
31	Spreading technique for slurry in Sweden 1998/99 According to Statistics Sweden Entire country 66% splash plate 26% trailing hoses 8 % technique unknown Southern Sweden 43 % splash plate 56% trailing hoses 1% technique unknown
32	Advantages and disadvantages, shallow injection versus traditional technique Advantages: Low ammonia losses Improved feed quality Higher N-utilisation Low odour emissions Disadvantages: Increased power requirement Increased spreading costs Risk for damage in ley
33	Harvested winter wheat after broadcast and band spreading of slurry at different occasions
34	Hygienic risks in grassland cropping
