Abstract

Background

Struvite, biochar and ash products (collectively known as STRUBIAS) derived from different waste streams are used as fertilisers in agriculture. Raw dairy processing sludge (DPS) shows promise as bio-based fertilisers, but secondary STRUBIAS-derived products need further testing as fertilisers.

Aims

The objective of this study was to calculate the phosphorus mineral fertiliser equivalency (P-MFE) for some STRUBIAS products derived from DPS.

Methods

Ryegrass (Lolium perenne L.) and wheat (Triticum aestivum) pot trials were used to determine the P-MFE using the apparent P recovery (APR) method for Fe-DPS and DPS-derived struvites (Struvite 1–4), hydrochars (HC1–3) and ash.

Results

The tested STRUBIAS products can be divided into two groups: (1) a range of products that can (i.e. Struvite 1–3) and (2) cannot (i.e., Struvite 4, HC1–3, ash and Fe-DPS) be considered fertilisers. In the first group, the P-MFE ranged from 66.8% to 76.7% for ryegrass and from 77.9% to 93.5% for spring wheat grain. In the second group, the P-MFE ranged from 7.8% to 58.3% for ryegrass and from −34.5% to −151.3% for spring wheat grain. The negative agronomic effects of some products for wheat grain (struvite and HC) in this study were mainly caused by high Fe content, which could be overcome by improved treatment processes.

Conclusions

Future policy and research must be aware that not all the DPS-derived STRUBIAS products are suitable as fertilisers and therefore need to be tested individually.

使用黑麦草（Lolium perenne L.）和春小麦（Triticum aestivum）的乳制品加工污泥衍生 STRUBIAS 产品的磷肥等效值

从不同废物流中提取的硬石膏、生物炭和灰烬产品（统称为 STRUBIAS）被用作农业肥料。未加工的乳制品加工污泥（DPS）有望用作生物基肥料，但从 STRUBIAS 中提取的次生产品还需要进一步测试才能用作肥料。

期刊介绍： Established in 1922, the Journal of Plant Nutrition and Soil Science (JPNSS) is an international peer-reviewed journal devoted to cover the entire spectrum of plant nutrition and soil science from different scale units, e.g. agroecosystem to natural systems. With its wide scope and focus on soil-plant interactions, JPNSS is one of the leading journals on this topic. Articles in JPNSS include reviews, high-standard original papers, and short communications and represent challenging research of international significance. The Journal of Plant Nutrition and Soil Science is one of the world’s oldest journals. You can trust in a peer-reviewed journal that has been established in the plant and soil science community for almost 100 years. Journal of Plant Nutrition and Soil Science (ISSN 1436-8730) is published in six volumes per year, by the German Societies of Plant Nutrition (DGP) and Soil Science (DBG). Furthermore, the Journal of Plant Nutrition and Soil Science (JPNSS) is a Cooperating Journal of the International Union of Soil Science (IUSS). The journal is produced by Wiley-VCH. Topical Divisions of the Journal of Plant Nutrition and Soil Science that are receiving increasing attention are: JPNSS – Topical Divisions Special timely focus in interdisciplinarity: - sustainability & critical zone science. Soil-Plant Interactions: - rhizosphere science & soil ecology - pollutant cycling & plant-soil protection - land use & climate change. Soil Science: - soil chemistry & soil physics - soil biology & biogeochemistry - soil genesis & mineralogy. Plant Nutrition: - plant nutritional physiology - nutrient dynamics & soil fertility - ecophysiological aspects of plant nutrition.
