34鸟粪石、生物炭和灰烬产品（统称为生物质）来自不同的废物流35，在农业中用作肥料。原乳制品加工污泥（DPS）显示出作为生物基肥料的前景，但其二次生物衍生产品需要作为肥料进行测试。本试验对多年生黑麦草（Lolium perenne L.））和小麦（Triticum aestivum）的盆栽试验是使用表观磷回收率（APR）方法39计算Fe-DPS和DPS衍生的鸟粪石（鸟粪石1 - 4）、水焦（HCl- 3）和灰分的磷矿物肥料当量（P-MFE）。结果显示，产品可分为两类：（1）一系列产品（即，鸟粪石1 - 3）41和（2）不能（即，鸟粪石4、HC 1 - 3、灰分和Fe-DPS）被认为是肥料。在第一组中，42的P-MFE范围为66.8%至76.7%的黑麦草和77.9%至93.5%的春小麦籽粒。第二组43粒，黑麦草的P-MFE为7.8 ~ 58.3%，44粒春小麦的P-MFE为-34.5 ~-151.3%。本研究中的部分产品（鸟粪石和45 HC）对小麦籽粒的负面农艺效应主要是由高铁含量引起的，可通过改进46个处理工艺加以克服。未来的政策和研究必须意识到，并非所有的BABIAS产品都适合作为肥料，因此需要单独测试
34 Struvite, biochar and ash products (collectively known as STRUBIAS) derived from different waste 35 streams are used as fertilisers in agriculture. Raw dairy processing sludge (DPS) shows promise as 36 bio-based fertilisers, but their secondary STRUBIAS-derived products need testing as fertilisers. The 37 objective of this ryegrass ( Lolium perenne L. ) and wheat ( Triticum aestivum ) pot trial was to calculate 38 their phosphorus mineral fertiliser equivalency (P-MFE) using the apparent P recovery (APR) method 39 for Fe-DPS and DPS-derived struvites (Struvite 1 – 4), hydrochars (HC1 – 3) and ash. Results showed 40 that the products can be divided into two groups: (1) a range of products that can (i.e., Struvite 1 – 3) 41 and (2) cannot (i.e., Struvite 4, HC1 – 3, ash and Fe-DPS) be considered as fertilisers. In the first group, 42 the P-MFE ranged from 66.8 to 76.7% for ryegrass and from 77.9 to 93.5% for spring wheat grain. In 43 the second group, the P-MFE ranged from 7.8 to 58.3% for ryegrass and from -34.5 to -151.3% for 44 spring wheat grain. The negative agronomic effects of some products for wheat grain (struvite and 45 HC) in this study were mainly caused by high Fe content which could be overcome by improved 46 treatment processes. Future policy and research must be aware that not all STRUBIAS products are 47 suitable as fertilisers and therefore need to be tested individually
