“…Currently abattoir waste can be recycled to land in the form of meat and bone meal (MBM) fertilizers, which are produced from pressure sterilizing animal carcasses to reduce the risk of disease transmission [20]. However, the plant availability of P in these fertilizers is low, typically 50% in the first year after application [21], and therefore yield from these fertilizers tends to be lower than from single or triple superphosphate [13, 14]. In contrast, this study showed Thallo ® to have an equal or greater biomass production compared to the mineral fertilizers.…”

“…bones, hooves, tail, and skin), although ‘specified risk materials’ for bovine spongiform encephalopathy (such as the brain and spinal cord) must be disposed of separately. Fertilizers made from bone meal have been tested against conventional fertilizers in the past, usually showing a fertilization rate between that of phosphate rock and super or triple super phosphates [13, 14], but the focus of these types of studies is predominantly on yield or NPK uptake. Furthermore, Thallo ® differs from meat and bone meal (MBM) fertilizers because meat trim is removed for human consumption, leaving the bone apatite and organic wastes which are first sterilised and then solubilised via an aggressive chemical reaction, and additional industrial by-products are added to improve the nutrient content.…”

Our food security depends on finding a sustainable alternative to rock phosphate for fertilizer production. Furthermore, over 2 billion people worldwide are currently affected by micronutrient deficiencies, and crop concentrations of essential minerals are declining. This paper examines whether a novel multi-element fertilizer, Thallo ® , can produce crop yields comparable to conventional rock phosphate derived fertilizers, and have an additional benefit of increasing essential mineral concentrations. Thallo ® , produced from abattoir and recycled industrial by-products, was tested against conventional mineral fertilizers in a pot trial with wheat and grass. In soil, yields were comparable between the fertilizer types, but, in a low-nutrient substrate, Thallo ® showed a yield benefit. Elemental concentrations in the plant material typically reflected the relative concentrations in the fertilizer, and Thallo ® fertilized plants contained significantly more of some essential elements, such as selenium and zinc. Furthermore, concentrations of the toxic element cadmium were significantly lower in Thallo ® fertilized crops. Among the fertilizers, manganese concentrations were greatest in the Thallo ® , but within the fertilized plants, they were greatest under the mineral fertilizer, showing the complexity of assessing whether nutrients will be taken up by crops. In summary, fertilizers from livestock waste have the potential to improve wheat and grass concentrations of essential elements while maintaining yields.

“…The underlying concept is circular economy fertilization and has been reviewed before (Solovchenko et al, 2016). Various methods have been used to recover nutrients from wastewater for agricultural purposes, including sewage sludge (directly or treated) (Duboc et al, 2017), precipitation of nutrients as struvite (Rahman et al, 2011), and algae cultivation. Besides approaches to mainly clean water with algae cultivation (e.g., Powell et al, 2008;Shilton et al, 2012) others were aimed to specifically produce algae biomass from simulated waste water (Gimondo et al, 2019) or real waste water (Mulbry et al, 2005) or different purchased species (Alobwede et al, 2019) to be used as a fertilizer on different plant species.…”

Wheat Can Access Phosphorus From Algal Biomass as Quickly and Continuously as From Mineral Fertilizer

Algae can efficiently take up excess nutrients from waterways, making them a valuable resource potentially capable of replacing synthesized and mined fertilizers for agriculture. The capacity of algae to fertilize crops has been quantified, but it is not known how the algae-derived nutrients become available to plants. We aimed to address this question: what are the temporal dynamics of plant growth responses to algal biomass? to better propose mechanisms by which plants acquire nutrients from algal biomass and thereby study and promote those processes in future agricultural applications. Data from various sources were transformed and used to reconstruct the nutrient release from the algae Chlorella vulgaris and subsequent uptake by wheat (Triticum aestivum L.) (as reported in Schreiber et al., 2018). Plants had received 0.1x or 1x dried algae or wet algae, or zero, 0.1x or 1x mineral fertilizer calculated from agricultural practices for P application and grown to 55 days in three soils. Contents of P and other nutrients acquired from algae were as high as from mineral fertilizer, but varied based on moisture content and amount of algae applied to soils (by 55 days after sowing plants with 1x mineral fertilizer and 1x dried algae had 5.6 mg P g DWshoot; 2.2-fold more than those with 0 or 0.1x mineral fertilizer, 0.1x dried algae and wet algae, and 1x wet algae). Absolute and relative leaf area growth and estimated P uptake rates showed similar dynamics, indicating that wheat acquires P from algae quickly. A model proposes that algal fertilizer promotes wheat growth after rapid transformation in soil to inorganic nutrients. We conclude theoretically that phosphorus from algal biomass is available to wheat seedlings upon its application and is released gradually over time with minor differences related to moisture content on application. The growth and P uptake kinetics hint at nutrient forms, including N, and biomass stimulation worthy of research to further exploit algae in sustainable agriculture practices. Temporal resolved phenotype analyses in combination with a mass-balance approach is helpful for understanding resource uptake from recycled and biofertilizer sources by plants.

“…Single-chemical extractions are used to predict soil and fertilizer P availability (Kratz et al, 2010), but Vogel et al (2017) showed that the diffusive gradients in thin films (DGT) technique was more powerful when applied to soil-fertilizer mixtures (including recycling fertilizers) to predict maize (Zea mays L.) biomass production and P uptake than classical chemical extractions. Similarly, Duboc et al (2017) found that DGTextractable P from soil-fertilizer mixtures explained 90% of the P taken up by rye. As DGT is sampling diffusive P, these results suggest that the potential of a fertilizer to sustain the P nutrition of a crop is related to its ability to release P to the soil solution.…”

Predicting Phosphate Release from Sewage Sludge Ash Using an Ion Sink Assay

et al. 2019

Thermochemical treatments allow production of sewage sludge ash (SSA) rich in P and low in heavy metals, which could be recycled in agriculture. Our objective was to quantify P release from SSA using ion sink assays and to relate these results to P speciation in SSA and plant P uptake. Anion and cation exchange membranes saturated with different counterions (HCO3, Na, and H) were used to create a gradient in pH, P, or cation concentration between SSA particles and the surrounding solution. Phosphorus speciation in SSA was assessed using X‐ray powder diffraction, and plant P uptake was determined in a pot experiment with an acidic and a neutral soil. Four SSA products were investigated: a SSA thermochemically treated with CaCl2 or MgCl2 (SSA Ca/Mg), a SSA blended with KCl, and a SSA blended with KCl and triple superphosphate (TSP) to obtain a marketable 12–20 P–K fertilizer. The H membranes dissolved all P species present in SSA. Combined HCO3/Na membranes extracted diffusible P and noncrystalline P from SSA Ca/Mg and stanfieldite from SSA Mg. Blending with KCl hardly changed P release from SSA, whereas blending with TSP masked P release. The amount of P extracted from SSA by combined HCO3/Na membranes was correlated to plant P use in the acid soil, whereas the amount of P extracted by HCO3 membranes alone was correlated to P use in the neutral soil. In conclusion, the ion sink assays delivered information on P release that was related to both SSA mineralogy and P use by plants. Core Ideas Ion exchange membranes are proposed to predict P release from sewage sludge ash (SSA) products. Combined HCO3/Na membranes extract diffusible and noncrystalline P from SSA products. Combined HCO3/Na membranes extract P from stanfieldite in MgCl2–treated SSA products. Hydrogen‐saturated membranes solubilized most of the P present in SSA products. Blending CaCl2–treated SSA with KCl does not affect the amounts of extractable P.
