Sediment removal from eutrophicated shallow lakes may not only be an effective method for lake restoration but also provides the potential recycling nutrients sediments to crop production. However, finding a suitable strategy sustainably reusing sediment remains challenge. Therefore, current study focused on best practices in applying soil terms of grass yield, nutrient uptake, and leaching. During nine-month lysimeter experiment, 100-cm high columns were filled with six combinations soil,...
Abstract Sustainable management of lakes requires us to overcome ecological, economic, and social challenges. These challenges can be addressed by focusing on achieving ecological improvement within a multifaceted, co‐beneficial context. In‐lake restoration measures may promote more rapid ecosystem responses than is feasible with catchment alone, even if multiple interventions are needed. In particular, we identify methods that support the overarching societal target circular economy through...
Mankind is taking advantage of numerous services by small shallow lakes such as drinking water supply, irrigation, and recreational function; however, many these suffer from eutrophication. Given the key role phosphorus (P) in eutrophication process, one effective restoration methods especially for removal sediments enriched with nutrients. In our study, we used interannual, seasonal, spatial data to examine changes sediment P mobility after 2016 a 1-ha highly eutrophic lake. We measured...
Soil organic matter (SOM) is a major driver of key agroecosystem functions. Our objective was to examine the dynamics in whole soil, particulate (POM; >53 μm size), and mineral-associated (MAOM) fractions under varying crop rotations nutrient managements at two long-term experimental sites (Breton Lethbridge). samples were collected from simple (2 yr) complex (5 or 6 5–10 cm depth. We found associations between SOM pools versus microbial community soil aggregation. Compared cropped soils, an...
Inefficient use of phosphorus (P) fertilizers leads to the transfer P into water bodies, causing their eutrophication. Sediment removal is a promising lake restoration strategy that removes nutrients including accumulated in sediments, and opens opportunity removed agriculture. In present study, we investigated effects using thick layer sediment from eutrophic Lake Mustijärv on plant growth, estimated environmental impacts different application methods by analyzing greenhouse gas emissions,...

In this study, we used a Hedley fractionation scheme diffusive gradient thin film (DGT) method determine P availability 83 NRSS originating Finland, Sweden, Germany. Furthermore, two independent short- long-term growth experiments with barley (Hordeum...
A field experiment was conducted to examine the effect of integrated use organic and mineral N fertilizer on yield attributes wheat. Treatments included: Control; full recommended (120 kg ha − 1); 90 + farm yard manure (FYM); ½ ½FYM, 30 FYM; dose FYM alone. Wheat variety Inqulab-91 used as a testing crop. Results indicated significant response wheat both fertilization. The morphological characteristics crop increased significantly with maximum observed at highest rate (mineral 150 120 P2O5...
Soil quality (SQ) indicators such as plant available water (PAW), soil organic carbon (SOC), and microbial biomass (MBC) can reveal agroecological functions; however, their spatial variabilities across contrasting land uses need to be better understood. This study examined the variation of these key SQ a function two land-use systems using topography covariates. We sampled total 116 point locations in native grassland (NG) site an irrigated cultivated (IC) located near Brooks, Alberta....
Lake Mustijärv was reconstructed by sediment removal following an almost complete siltation. Here we evaluate challenges and opportunities for the management of lake. We focused on stream discharging to lake (i.e., external loading), retention in accumulation basins internal processes) as well ecosystem-level response stressors based biological variables (phyto- zooplankton, macrophytes, fishes zoobenthos). Urban agricultural inputs elevated ammonium total phosphorus concentrations lake,...
Water scarcity encourages municipalities to use more precise irrigation systems in arid urban landscapes. However, major concerns are associated with the adaptation of mature trees new after they have matured under traditional management. We investigated olive a change system from surface an automatic drip coarse-textured forest park. The growth indices eight-year-old were monitored for period 2012–2014 three systems: (1) automated (ADI) that basin-surface (TSI), (2) TSI since plantation,...
Inefficient use of phosphorus (P) fertilizers leads to the transfer P into water bodies, causing their eutrophication. Sediment removal is a promising restoration strategy that permanently removes accumulated in lake sediments, and opens opportunity sediment agriculture. There paucity multi-year field studies on effects recycling nutrient-rich sediments crops environment. In present study, we investigated using from 1- ha eutrophic Lake Mustijärv plant growth, also estimated environmental...
