Policies to promote environmentally sustainable fertilizer use and supply to 2020 by Bumb, Balu L., Baanante, Carlos A.

“…In the early 1990s, however, fertilizer became a target of criticism mainly because of heavy use in the developed countries, where it was suspected of having an adverse impact on the environment through nitrate leaching, eutrophication, greenhouse gas emissions, and heavy metal uptakes by plants. Consequently, fertilizer use per se was mistakenly identified as an enemy of the environment. …”

Nutrient composition of dried marine small fish in Bangladesh and their potential to address hidden hunger by Mamun, Abdullah-Al, Rifat, M. A., Abdul, Wahab, Rahman, Muhammad, Nahiduzzaman, Md, Thilsted, Shakuntala, Kjellevold, Marian

“…Locally known as chapila, chewa, faissa, ichre, loittya, mola, and olua, these fish were collected, dried to a moisture content consistent with local practices, pulverized, and subjected to analysis for proximate composition, mineral content, vitamin levels, heavy metal presence, and fatty acid profile. While the dried fish samples exhibited high nutritional quality, significant variations were observed among species for each nutrient analyzed. …”

Soil biodiversity and ecological intensification for sustainable agriculture by Erktan, Amandine, Blanchart, Eric, Pulleman, Mirjam, Trap, Jean

“…This special issue gathers thirteen original studies investigating the influence of soil biodiversity (bacteria, fungi, nematodes, collembolans, earthworms, and plant roots) on soil functions, namely soil C transformation and nutrient cycling, soil structure maintenance, biological pest regulation, water regulation and metal contaminant mitigation. Whether in field or microcosms conditions, most articles in this special issue focus on how agroecological practices impact the nexus between soil biodiversity-soil functioning and sustainable crop production (soil/crop management). …”

Iron biofortification in rice: An update on quantitative trait loci and candidate genes by Swamy, B.P. Mallikarjuna, Marathi, Balram, Ribeiro-Barros, Ana I. F., Calayugan, Mark Ian C., Ricachenevsky, Felipe Klein

“…Among the candidate genes associated with Fe uptake, translocation, and loading into rice grains, we highlight the function of transporters from the YSL and ZIP families; transporters from metal-binding molecules, such as nicotianamine and deoxymugineic acid; vacuolar iron transporters; citrate efflux transporters; and others that were shown to play a role in steps leading to Fe delivery to seeds. …”

Rice biofortification with zinc and selenium: a transcriptomic approach to understand mineral accumulation in flag leaves by Roda, Faustino Adriano, Marques, Isabel, Batista-Santos, Paula, Esquível, Maria Glória, Ndayiragije, Alexis, Lidon, Fernando Cebola, Swamy, B.P. Mallikarjuna, Ramalho, José Cochicho, Ribeiro-Barros, Ana I.

“…Flag leaves play an important role in plant photosynthesis and provide sources of metal remobilization for developing grains. A total of 3170 differentially expressed genes (DEGs) were identified. …”

Calcium inhibits bap-dependent multicellular behavior in Staphylococcus aureus by Arrizubieta, M. J., Toledo-Arana, Alejandro, Amorena, B., Penadés, José R., Lasa, Inigo

“…Addition of manganese, but not addition of magnesium, also inhibited biofilm formation, whereas bacterial aggregation in liquid media was greatly enhanced by metal-chelating agents. In contrast, calcium or chelating agents had virtually no effect on the aggregation of Bap-deficient strain M556. …”

Farmers’ preferences for fertilizers derived from domestic sewage and kitchen waste – A discrete choice experiment in Germany by Utai, Katrin, Narjes, Manuel, Krimly, Tatjana, Lippert, Christian

“…The average WTP drops considerably if a fertilizer’s heavy metal contents are relatively high and if the absence of drug residues cannot be guaranteed, whereas a customizable nutrient composition and a constant supply availability would have a sales promoting effect. …”
