“…Whereas a share of this organic P is recycled directly on agricultural land, a number of concerns are associated to the landspreading of unprocessed biogenic materials. At first, specific organic wastes may contain a broad set of pollutants, which could be hazardous for the environment and may pose a risk to human health (Alvarenga et al 2016;Charlton et al 2016a;Charlton et al 2016b;Harrison et al 2006;Lowman et al 2013;McBride 2003). This relates in particular to the presence of potentially toxic metals and metalloids or pathogens, as well as emerging concerns over a wide range of organic bioactive substances, such as antibiotics, organo-metalloids, and endocrine-disrupting substances.…”

Phosphorus (P) is a macronutrient essential for all living organisms. Food production has become highly dependent on mineral Pfertilisers derived from phosphate rock, a non-renewable and finite resource. Based on supply risk and economic importance for the European Union, phosphate rock and elemental P have been identified as critical raw materials. Moreover, P dissipation can lead to adverse impacts on the aquatic environment. The production and use of P-fertilisers derived from secondary raw materials could possibly contribute to a more sustainable agriculture in line with a circular economy. Biogenic and industrial resources and waste streams can be converted into value added materials, such as precipitated phosphate salts, thermal oxidation materials and derivates, and pyrolysis and gasification materials. A condition is, however, that the P must be recovered in a plant-available form and that the recovered P-fertiliser supports plant growth and nutrient uptake in European agroecosystems. Here, we review the agronomic efficiency of selected P-fertilisers derived from secondary raw materials by comparing plant responses relative to those after mined and synthetic P-fertiliser application in settings relevant for European agriculture, using meta-analyses. The major points are the following: (1) precipitated phosphate salts show similar agronomic efficiency to mined and synthetic Pfertilisers, with results that are consistent and generalisable across soil and crop types relevant for European agriculture; (2) thermal oxidation materials and derivates can deliver an effective alternative for mined and synthetic P-fertilisers, but the relative agronomic efficiency is dependent on the feedstock applied, possible post-combustion manufacturing processes, and the length of the plant growing season; (3) the agronomic efficiency of pyrolysis and gasification materials remains indeterminate due to a lack of available data for European settings. It is concluded that the agronomic efficiency of selected P-fertilisers derived from secondary raw materials supports their use in conventional and organic European agricultural sectors.

“…Organic wastes with high organic content are an excellent potential source of plant nutrients in agricultural soils, particularly potassium and nitrogen, which may be applied as a nutrients supplier/corrective organic thereby reducing landfill disposal and ensuring the recycling of nutrients by the increase of microbial biomass (Alvarenga et al, 2015;.…”

The yeast production industry (e.g. distillery, brewing, baking industries) has been growing globally over the last years generating a large amount of sub-products. Laboratory experiments, under controlled conditions, were performed to investigate the impact of yeast waste application to a sandy texture soil. Experimental treatments were: surface application of yeast and decanted-yeast (CMSs and CMSds), surface application of yeast and decantedyeast followed by incorporation in the 0-5 cm soil layer (CMSm and CMSdm), surface application of ammonium nitrate (AN) (not applied in short-term experiment) and a control (soil only) (CTR). The amount of yeast applied was 2 g in the short-term experiment and equivalent to 170 kgN.ha-1 in the long-term experiment. A short-term (38-day period) leaching experiment was performed with 5 weekly irrigation events (5 treatments × 3 replications) to assess N, P, K losses. Results showed that yeast application increased NH4 + , PT and KT leaching relative to control while decreased NO3leaching relative to a high initial content of control, during first irrigation events. Incorporation treatments increased NH4 + , NO3and PT losses earlier. KT losses were higher in surface treatments. A long-term leaching experiment (73-day period) with 6 irrigation events every two weeks was then performed (6 treatments × 4 replicates) to assess N, P losses. A two parallel incubation experiment (6 treatments × 3 replicates) were simultaneously performed to measure GHG emissions (CO2, N2O, CH4) and to assess the N mineralization in each treatment. Results showed that yeast application increased initial NH4 + concentration in leachates and soil relative to control and NO3increased afterwards. N2O and CO2 increased significantly relative to control on the first days after yeast application. AN treatment emissions were very similar to control but had a small increase of N2O. CH4 emissions were insignificant. The global warming potential (GWP) of yeast and AN were 6× and 2× times higher than control, respectively.

“…Both are branchiopod crustaceans, a taxon more closely related to insects than are malacostracan crustaceans (e.g., Parhyale hawaiensis [26,27]). Thamnocephalus live in temporary freshwater ponds [28] and their life cycle includes desiccation-resistant encysted eggs (giving rise to commercially available cysts, primarily for toxicology studies, e.g., [29]). After rehydration, cysts hatch as swimming larvae with three pairs of head appendages and an undifferentiated trunk.…”

Background: Segmentation in arthropods typically occurs by sequential addition of segments from a posterior growth zone. However, the amount of tissue required for growth and the cell behaviors producing posterior elongation are sparsely documented. Results:Using precisely staged larvae of the crustacean, Thamnocephalus platyurus, we systematically examine cell division patterns and morphometric changes associated with posterior elongation during segmentation. We show that cell division occurs during normal elongation but that cells in the growth zone need only divide ~ 1.5 times to meet growth estimates; correspondingly, direct measures of cell division in the growth zone are low. Morphometric measurements of the growth zone and of newly formed segments suggest tagma-specific features of segment generation. Using methods for detecting two different phases in the cell cycle, we show distinct domains of synchronized cells in the posterior trunk. Borders of cell cycle domains correlate with domains of segmental gene expression, suggesting an intimate link between segment generation and cell cycle regulation. Conclusions:Emerging measures of cellular dynamics underlying posterior elongation already show a number of intriguing characteristics that may be widespread among sequentially segmenting arthropods and are likely a source of evolutionary variability. These characteristics include: the low rates of posterior mitosis, the apparently tight regulation of cell cycle at the growth zone/new segment border, and a correlation between changes in elongation and tagma boundaries.
