自1980年以来，一项双因素施肥试验在4个大田轮作中比较了3种肥料类型(添加和不添加生物动力制剂的农家肥和无机肥)在3种不同的施肥量下的效果。除施肥外，所有处理的所有其他耕作要素都相同，并遵循正常的有机耕作做法。报告了20多年来在土壤参数(例如有机碳含量、微生物生物量和活性、颗粒有机质、氨基酸含量、碳源利用、微量营养素)、作物参数(产量形成取决于施肥和立地条件、菌根发育)和杂草丰度方面取得的关键结果。
Since 1980 a 2 factor fertilization experiment compares 3 fertilization types (farmyard manure with and without biodynamic preparations vs. inorganic fertilizers) applied at 3 different rates in a 4 field crop rotation. Except for fertilization all other elements of cultivation were the same in all treatments and followed normal organic farming practices. The key results of the experiment obtained in more than 2 decades are reported with respect to soil parameters (e.g. organic carbon content, microbial biomass and activity, particulate organic matter, amino acid content, carbon source utilization, micronutrients), crop parameters (yield formation depending upon fertilization and site conditions, mycorrhiza development) and weed abundance.
