SOLID-DSS / Sustainable Organic and Low-Input Dairying - Decision Support System / github project

Usage

This decision support system helps you to estimate the longterm balance of forage supply grown on arable & grassland and demand from your dairy herd and identify potential shortages and overconsumption. Before you run the simulation you should go through these steps:

  • Set your location and edit soil parameters.
  • Set the properties of your dairy herd.
  • Edit your rotations if you produce forage crops on arable land.
  • Set grassland and pasture availability.
  • Check yor inputs here and finally run the simulation.
  • View results here, adjust simulation parameters and run the simulation again if necessary.

Please find additional help and more background information on our Wiki pages.

Crop rotation

Drag and drop crops into the rotation, connect them and edit their properties. Only forages (maize silage and grass-legume) will be used in the diet calculations. Add the amout of concentrates available at purchased feeds.
