This mod improves the quality of slurry, manure and digestate in the game, by decreasing the amount used when it is used for as fertilizer. In the base game, it is always more financially beneficial to sell slurry, manure and digestate and buy liquid of solid fertilizer, even on hard economic difficulty.

The amount used is reduced by more than half, which makes it financially equal to liquid or solid fertilizer on normal difficulty, but also make it easier to apply as it requires fewer refills. On hard difficulty it is better to use than to sell (as the sell price is reduced). On easy difficulty it is still slightly better to sell and to use the easier liquid and solid fertilizer.
