Use manure, slurry and digestate without running back to refill after every few passes. This mod lowers how much organic fertilizer your fields need, so animal by-products finally become practical and worthwhile to spread. Precision Farming is fully supported, and multiplayer works too. Out of the box it uses just 40% of the normal amount — roughly 2.5x less material. Organic fertilizer usage can be set in the XML file created in your /modSettings directory, anywhere in the 0.01 - 1.0 range.
