Phosphorus (P) flow from deposits through agriculture to waterways leads eutrophication and depletion of P reserves. Therefore, must be recycled. Low unpredictable plant availability in residues is considered a limiting factor for recycling. We identified the determinants plant-availability agrifood residues. quantified Italian ryegrass (Lolium multiflorum) field soil fractions with different availabilities as response manure sewage sludge range capture hygienization treatments. was more...
Recent research suggests that anthropogenic nutrient flows may have transgressed the regulatory capacity of earth. Agrifood systems account for most flows, and food supply is limited more by reducing excessive than phosphorus (P) reserves or population growth. The primarily P flow tolerated freshwater ecosystems next needed reduction in conversion nitrogen (N) to reactive form fertilizer manufacture, legume cultivation fossil fuel combustion. required N would reduce 250 710 kcal capita−1...
Phosphorus (P) extractability, and thus plant-availability, in processed agrifood residues incorporated soil is not directly related to the extractability before incorporation. However, release of P has been demonstrated over seasons, mechanisms involved are well understood. We identified fate fractions manure sewage sludge with current methods after incubation for two weeks, 2.5 months 12 sandy loam or clay, using a modified Hedley fractionation scheme. also sorption soil, determinants. The...
Anthropogenic nutrient flows exceed the planetary boundaries. The boundaries and current excesses vary spatially. Such variations have both an ecological a social facet. We explored spatial variation using bottom-up approach. local critical were determined through or accumulated flow of preceding five years before boundary criteria met. Finland Ethiopia served as cases with contrasting ecology wealth. in excess depends on historical global inequities access to nutrients. Globally, use per...
The activation of nitrogen and phosphorus for food production has caused the transgression safe operating space Earth system. However, countries differ in use their fair share global nutrient activation, causing a disparity that severe implications environment, land degradation security. Both impact on system processes as well productivity gains losses consequent socio-economic impacts depend past use. Therefore, this study, we examined how relation to countries' shares evolved globally....
Nitrogen (N) and phosphorus (P) cycles are absolutely vital in maintaining sustainable food systems. Human activities disturb the natural balance of these by creating enormous additional nutrient fluxes, causing eutrophication waterways pollution land To tackle this problem, management is required. This paper addresses two countries: The Netherlands Finland. We adopt a critical perspective on resource politics, especially towards opportunistic policy strategies for pollutant N P. Two...
Biodegradable waste quantities in Lithuania and their potential for the co-treatment renewable energy organic fertilizer production were investigated. Two scenarios formulated to study differences of amounts obtainable fertilizers between different ways utilization. In first scenario, only digestion was used, second materials other than straw digested, solid fraction sewage sludge digestate combusted. As a result, heat electricity, as well counties obtained both scenarios. Based on this...
Two field experiments, conventional grass ley and organic grass-clover ley, were established with barley as a nurse crop in spring 2000 given either low or high fertilization mineral fertilizer (Mineral) composts. The compost types municipal biowaste (Biowaste), + sewage sludge (BioSludge) cattle manure (Manure). Plant yields nitrogen (N) uptakes measured for three years efficiency of N utilization was estimated. In single application compost, the total mainly form less than 10% inorganic...
Processing of organic residues may affect plant-availability phosphorus (P) and thus the potential to recycle nutrient, i.e., recyclability, but empirical evidence in field is lacking. In experiments clay silt loam soils with low available P, impact on P recyclability by cattle manure sewage sludge processing methods (composting, anaerobic digestion, lime-stabilization, acid-oxidizer) three application rates were assessed. Synthetic nitrogen (N) potassium (K) fertilizers supplied surplus NPK...
Nautojen jaloittelu- ja ulkotarhat sekä hevostarhat ovat yleistyneet viime vuosina. Syynä on mm. parsinavetoissaolevien lehmien hiehojen laidunnussäännös, joka voidaan korvata jaloittelulla tarhassa.Myös suurten pihattonavettojen yhteyteen usein rakennetaan tarha, vaikka varsinaista ulkoilupakkoapihatossa pidettävillä eläimillä ei ole. Ulkotarhoissa kasvatetaan osan vuotta tai ympäri vuoden emolehmiäja lihanautoja. Viime vuosina hevosten määrän lisääntyessä rakennettu uusia talleja...
