我们应用厌氧消化产生的泥浆，未消化的泥浆，或无机氮（硝酸铵）或NPK复合肥盆草和草三叶草混合生长在两种土壤中。作物产量相等或提高与灌溉状态，土壤水分分析表明，有较少的潜力，通过淋失的养分。因此，用草酸盐代替无机肥可以保持草地生产力，但对环境的影响较小。
We applied digestate generated from the anaerobic digestion of slurry, undigested slurry, or inorganic N (ammonium nitrate) or NPK compound fertilizer to pots of grass and a grass–clover mix grown in two soils. Crop yields were equal or enhanced with digestate, and analysis of soil water showed that there was less potential for loss of nutrients via leaching. Replacing inorganic fertilizer with digestate may therefore maintain grassland productivity but with less impact on the environment.
