Manure Volume Estimates by Livestock Type and Land Use for England and Wales

Six livestock types generate manure volumes apportioned into managed and field-deposited categories across England and Wales at 10 km resolution. The MANURES-GIS model estimates quantities in kilograms for solid manure and litres for liquid manure, detailing flows from nine specific manure sources to four land destinations.

Use Cases

• Model nutrient runoff risk by analyzing manure volumes from dairy slurry and pig slurry sources applied to winter arable land.
• Assess livestock farming intensity by mapping total manure quantities from dairy cattle, beef cattle, and sheep across 10 km grid squares.
• Compare manure management practices by evaluating the split between managed farmyard manure and direct excreta from grazing for different livestock classes.
• Estimate organic fertilizer potential by aggregating broiler litter and layer manure volumes destined for grass and spring arable land.

Strengths

• Provides national-scale coverage for England and Wales.
• Distinguishes nine specific manure source types and four destination land uses.
• Data is modelled at a consistent 10 km spatial resolution.

Limitations

• Data is based on a 2008 model (MANURES-GIS), which may not reflect current farming practices or livestock populations.
• Estimates are modelled outputs, not direct measurements, introducing potential inaccuracies from underlying assumptions.
• The dataset lacks granular temporal detail, offering only annual estimates without intra-annual variation.
