“…Organic matter (OM) was then estimated after combustion for 4 h at 550 • C. Following [58], quantification of mineral elements was carried out by X-ray fluorescence, using a Thermo Scientific Niton XL3t 950 He GOLDD ± XRF. Electrical conductivity (EC) and pH were measured with a multiparameter analyzer (C 6030) and SP21 (pH) and SK20T (CE) electrodes, in a soil mixture with water (1:2.5 g soil mL −1 water milli-q ) under stirring after a thermal bath (25 • C) for 30 min [59].…”

This study aimed to assess the efficiency of Ca enrichment in tubers of three genotypes of Solanum tuberosum L., through foliar spraying with CaCl2 and Ca(NO3)2 solutions. In this context, soil heterogeneity of three potato-growing fields, as well as the implications of Ca accumulation among tissues and some quality parameters were assessed. Three potato varieties (Agria, Picasso and Rossi) were grown in three production fields and during the life cycle, four pulverizations with calcium chloride (3 and 6 kg ha−1) or calcium nitrate (0.5, 2 and 4 kg ha−1) were applied. For screening the potential phytotoxicity, using Agria as a test system, the potential synthesis of photoassimilates was determined, and it was found that after the 3rd Ca application, leaf gas exchanges were moderately (net photosynthesis), to strongly (stomatal conductance) affected, although without impact on Ca accumulation in tubers. At harvest, the average Ca biofortification index varied between 5–40%, 40–35% and 4.3–13% in Agria, Picasso and Rossi, respectively. Moreover, the equatorial region of the tubers in general showed that Ca accumulation prevailed in the epidermis and, in some cases, in inner areas of the potato tubers. Biofortified tubers with Ca also showed some significant changes in total soluble solids and colorimetric parameters. It is concluded that Ca enrichment of potato tubers through foliar spraying complemented the xylem mass flow of Ca from roots, through phloem redistribution. Both fertilizers showed similar efficiency, but Rossi revealed a lower index of Ca accumulation, eventually due to different metabolic characteristics. Although affected by Ca enrichment, potato tubers maintained a high quality for industrial processing.

“…In the case of insect meal, phosphorus (P) was determined by molecular absorption spectrophotometry according to ISO standard (1996) using a spectrophotometer (UV/Vis UV2, UNICAM, Cambridge, UK). For the determination of calcium (Ca) X-ray fluorescence method of Dispersive Energy (ED-XRF) was used, based on the methodology described by Pessoa (2016). Chitin was isolated from insect meal using a methodology described by Gamage and Shahidi (2007).…”

Global population is in constant growth, and so is its global protein demand. Aquaculture has been highlighted as one of the best possibilities to satisfy animal protein demand due to the remarkable efficiency of fish growth in comparison with terrestrial animals (Fry, 2018), and to its fast development as an industrial food sector. The most commonly farmed fish require aquafeeds with a high content in protein, whose demand has been traditionally satisfied with a significant inclusion of fishmeal (FM) in fish feeding formulations. In order to favour this continuous development in a sustainable way, the scientific and industrial communities have invested big efforts on

This study aimed to assess the implications of Zn enrichment in wheat grains as a function of contrasting genotypes, edaphic conditions and foliar fertilizers. Triticum aestivum L. varieties Roxo and Paiva were grown in four production fields, and sprayed with ZnSO4 (0, 16.20 and 36.40 kg/ha) Zn-EDTA (0, 6.30 and 12.60 kg/ha) and Tecnifol Zinc (0, 3.90 and 7.80 kg/ha). The heterogeneous edaphic conditions of the wheat fields were chemically characterized, it being found that soil properties determine different Zn accumulation in the grains of both genotypes. Foliar spraying enhanced to different extents Zn content in the grains of both genotypes, but the average of enrichment indexes varied among the wheat fields. Zinc mostly accumulated in the embryo and vascular bundle and to a lesser extent in the endosperm. Grain yield and test weight sprayed by ZnSO4 gave the highest values in both genotypes, but the opposite was found for Zn-EDTA. Considering the color parameters, lightness and red–green transitions were found to be a conjunction of genotype characteristics, fertilization types and edaphic conditions prevailing in each field. It is concluded that the index of Zn enrichment in wheat grains is a docket of edaphic conditions, genotype and type of fertilization.
