Global phosphorus shortage will be aggravated by soil erosion

Nature Communications, Journal Year: 2020, Volume and Issue: 11(1)

Published: Sept. 11, 2020

Abstract Soil phosphorus (P) loss from agricultural systems will limit food and feed production in the future. Here, we combine spatially distributed global soil erosion estimates (only considering sheet rill by water) with P content for cropland soils to assess loss. The world’s are currently being depleted spite of high chemical fertilizer input. Africa (not able afford costs fertilizer) as well South America (due non-efficient organic management) Eastern Europe (for a combination two previous reasons) have highest depletion rates. In future world, an assumed absolute shortage mineral fertilizer, worldwide be between 4–19 kg ha −1 yr , average losses due water contributing over 50% total losses.

Exploring phosphorus fertilizers and fertilization strategies for improved human and environmental health

Biology and Fertility of Soils, Journal Year: 2020, Volume and Issue: 56(3), P. 299 - 317

Abstract Mineral phosphorus (P) fertilizers support high crop yields and contribute to feeding the teeming global population. However, complex edaphic processes cause P be immobilized in soil, hampering its timely sufficient availability for uptake by plants. The resultant low use efficiency of current water-soluble creates significant environmental human health problems. Current practices increase have been inadequate curtail these We advocate understanding plant physiological processes, such as requirement, storage excess phytate, mechanisms, identify novel ways designing delivering plants improved uptake. note importance implications contrasting role micronutrients zinc iron stimulating under soil content, while inhibiting fertilization; this could provide an avenue managing different fertilization regimes. argue that improvement nutritional value crops, especially cereals, through reduced phytic acid increased contents should among most important drivers toward development innovative fertilizer products technologies.

Bio-based fertilizers: A practical approach towards circular economy

Bioresource Technology, Journal Year: 2019, Volume and Issue: 295, P. 122223 - 122223

Published: Oct. 3, 2019

Although for the past 100 years, fertilizer technologies have increasingly used renewable resources, majority of manufactured products are still based on mineral deposits and fossil fuels. The European Commission has set a goal 30% reduction non-renewable resources in production. This can only be accomplished if there incentives wastes valorization fines making use raw materials. will enable eutrophication surface waters due to presence nitrogen phosphorus, originating from agricultural fields fertilizers. biological waste is practical solution recover valuable components.

Environmental footprint family to address local to planetary sustainability and deliver on the SDGs

The Science of The Total Environment, Journal Year: 2019, Volume and Issue: 693, P. 133642 - 133642

Published: July 29, 2019

The number of publications on environmental footprint indicators has been growing rapidly, but with limited efforts to integrate different footprints into a coherent framework. Such integration is important for comprehensive understanding issues, policy formulation and assessment trade-offs between concerns. Here, we systematize published studies define family that can be used the sustainability. We identify overlaps analyse how they relate nine planetary boundaries visualize crucial information provide local In addition, assess delivers measuring progress towards Sustainable Development Goals (SDGs), considering its ability quantify pressures along supply chain relating them water-energy-food-ecosystem (WEFE) nexus ecosystem services. argue flexible framework where particular members included or excluded according context area concern.

Global Anthropogenic Phosphorus Loads to Freshwater and Associated Grey Water Footprints and Water Pollution Levels: A High‐Resolution Global Study

Water Resources Research, Journal Year: 2017, Volume and Issue: 54(1), P. 345 - 358

Abstract We estimate the global anthropogenic phosphorus (P) loads to freshwater and associated grey water footprints (GWFs) for period 2002–2010, at a spatial resolution of 5 × arc min, compare GWF per river basin runoff assess P‐related pollution level (WPL). The P load systems from both diffuse point sources is estimated 1.5 Tg/yr. More than half this total was in Asia, followed by Europe (19%) Latin America Caribbean (13%). domestic sector contributed 54% total, agriculture 38%, industry 8%. In agriculture, cereals production had largest contribution (31%), fruits, vegetables, oil crops, each contributing 15%. related be 147 10 12 m 3 /yr, with China 30%, India 8%, USA 7%, Spain Brazil 6% each. basins WPL > 1 (where exceeds basin's assimilation capacity) together cover about 38% land area, 37% discharge, provide residence 90% population.

Brazil's large land base is important for global food security but its high dependency on inorganic phosphorus (P) fertilizer crop production (2.2 Tg rising up to 4.6 in 2050) not a sustainable use of critical and price-volatile resource. A new strategic analysis current future P demand/supply concluded that the nation's secondary resources which are produced annually (e.g. livestock manures, sugarcane processing residues) could potentially provide 20% demand by 2050 with further investment recovery technologies. However, much larger legacy stores soil (30 2016 worth over $40 billion 105 more buffer against scarcity or sudden price fluctuations, enable transition input strategies reduce annual surpluses 65%.

Biochar-based slow-release of fertilizers for sustainable agriculture: A mini review

Environmental Science and Ecotechnology, Journal Year: 2022, Volume and Issue: 10, P. 100167 - 100167

Published: March 5, 2022

Increasing global population and decreasing arable land pose tremendous pressures to agricultural production. The application of conventional chemical fertilizers improves production, but causes serious environmental problems significant economic burdens. Biochar gains increasing interest as a soil amendment. Recently, more attentions have been paid biochar-based slow-release (SRFs) due the unique properties biochar. This review summarizes recent advances in development, synthesis, application, tentative mechanism SRFs. development mainly undergoes three stages: (i) amendment using biochar, (ii) interactions between nutrients (iii) Various methods are proposed improve fertilizer efficiency majorly including in-situ pyrolysis, co-pyrolysis, impregnation, encapsulation, granulation. Considering distinct features different methods, integrated promising for fabricating effective in-depth understanding nutrient loading slow release is discussed based on current knowledge. Additionally, perspectives challenges potential SRFs described. Knowledge surveyed from this indicates that applying viable way promoting sustainable agriculture.
