“…Evidence suggests that P is accumulating in some cropland soils (Yuan et al, 2018; Figure 7), which increases uptake by crop plants that may increase P concentrations in food and therefore dietary intake. Some studies have reported high levels of P uptake by crops (Fernandes, Soratto, Souza, & Job, 2017;Gomez, Magnitskiy, & Rodriguez, 2019;Selles, McConkey, & Campbell, 1999;Zhang, Greenwood, White, & Burns, 2007) and non-crop plants (Da Ros, Soolanayakanahally, Guy, & Mansfield, 2018;Ostertag, 2010;Xu & Timmer, 1998) under high soil P concentrations. However, the potential relationship between the global accumulations of P in crop soil and P concentrations in the food produced and subsequent consequences on human health are currently unknown.…”

The availability of carbon (C) from high levels of atmospheric carbon dioxide (CO2) and anthropogenic release of nitrogen (N) is increasing, but these increases are not paralleled by increases in levels of phosphorus (P). The current unstoppable changes in the stoichiometries of C and N relative to P have no historical precedent. We describe changes in P and N fluxes over the last five decades that have led to asymmetrical increases in P and N inputs to the biosphere. We identified widespread and rapid changes in N:P ratios in air, soil, water, and organisms and important consequences to the structure, function, and biodiversity of ecosystems. A mass‐balance approach found that the combined limited availability of P and N was likely to reduce C storage by natural ecosystems during the remainder of the 21st Century, and projected crop yields of the Millennium Ecosystem Assessment indicated an increase in nutrient deficiency in developing regions if access to P fertilizer is limited. Imbalances of the N:P ratio would likely negatively affect human health, food security, and global economic and geopolitical stability, with feedbacks and synergistic effects on drivers of global environmental change, such as increasing levels of CO2, climatic warming, and increasing pollution. We summarize potential solutions for avoiding the negative impacts of global imbalances of N:P ratios on the environment, biodiversity, climate change, food security, and human health.

BACKGROUND Most agricultural soils have low zinc (Zn) content available to crops, which results in a significant decrease in productivity and in public health problems. However, the priming of potato tubers in solutions with Zn can be an effective strategy for their fortification. In order to evaluate the effect of Zn concentrations and tuber priming time on the fortification and bioavailability of Zn, potato tubers were primed in solutions containing 0, 10, 20 and 30 mg mL−1 Zn during 12, 16, 20, and 24 h, respectively. The dry matter and the content of Zn and phytic acid (PA) in tubers were assessed in order to obtain the PA:Zn molar ratio. RESULTS Longer priming time increased the Zn content in the cortex of the tubers. High Zn concentration in the solution increased the content of Zn linearly in both the cortex and the central region of the tuber, whereas in the periderm the content levels adjusted to the non‐linear logistical model, showing saturation at a minimum of 10 mg mL−1 Zn in the solution. An increase in the bioavailability of Zn was verified when there was higher Zn concentration in the solution. CONCLUSION A substantial increase in Zn bioavailability was obtained by priming the tubers for 12 h in 10 mg mL−1 Zn. © 2019 Society of Chemical Industry

“…The response of the application of P in the total dry mass of the potato genotypes was defined by the propagative origin of the plants. Um fornecimento balanceado de nutrientes para a cultura da batata pode proporcionar maior absorção de P pelas plantas, maior rendimento de matéria seca e também pode interferir na maior absorção de outros nutrientes, que conjuntamente com o P, podem conferir aumento de produtividade (FERNANDES et al, 2017).…”
