Manure, composting and biogas

Manure and slurry nutrients per hectare, C/N ratio and composting windrow, and biogas volume and energy from the waste.

Manure: nutrients per hectare

Estimate the herd's annual manure production, the dose per hectare, and the nutrients reaching the area, with the nitrogen available in the first year.

Manure production and N, P₂O₅ and K₂O per hectare

Composting: C/N ratio

Calculate the C/N ratio of a mix of composting materials and how much of one of them to add to reach the target ratio.

Mix C/N ratio and how much to adjust

Manure biogas

Estimate the volume of biogas, methane, and the thermal and electrical energy that the herd's manure can generate in a biodigester.
