“…Similar findings for TP in the studied area were reported by Wysocka- Czubaszek et al [2018] who observed TP enrichment of soils on the toeand footslope. The results of this study are also in a good agreement with Zhang et al [2008] who reported erosional spatial distribution of P in the hilly landscape.…”

“…Erosion strongly influences the soil properties, especially in complex landscapes where surface cation exchange, water-holding capacities and soil organic carbon (SOC), total nitrogen (TN) and total phosphorus (TP) concentrations are higher in depositional areas, comparing to the eroded parts [Wysocka-Czubaszek 2012; Wysocka- Czubaszek et al 2018]. Soil erosion depletes the SOC stock in arable land and deposits SOC in aquatic ecosystems or in depressional sites where its labile forms may be subjected to decomposition, which leads to the emission of carbon dioxide (CO 2 ) under aerobic conditions and methane (CH 4 ) under anaerobic conditions.…”

Erosion strongly influences the soil properties and affects the intra-field variation of nutrients not only in steep young morainic landscapes but also on gentle slopes of old-glacial landscapes. The aim of the study was the evaluation of changes in the plant-available nutrient contents in the complex old-glacial eroded landscape of the Bielska Plain in the northeastern part of Poland. The soil samples were collected from the soil profiles located along the transect beginning on the flat summit of the kame hummock extending through south-facing convex slope, the toeslope and footslope and further through the north-facing uniform slope. The content of plant-available forms of phosphorus (P dl) and potassium (K dl) and mineral forms of nitrogen (NH 4-N and NO 3-N) were determined in every soil profile. The soils located in various landscape positions were characterized with different fertility. In the soil located on the toeslope the content of NO 3-N, P dl and K dl was high, while the soil located on the summit was rich in NH 4-N and poor in the plant-available forms of K and P. The erosional distribution of plant-available N, P and K enhances the variation of nutrient content within one field and contributes to high variability of crops.

“…This is likely because most of the labile carbon is turned into biogas through the AD process, resulting in a digestate with less substrate present and so a lower potential for formation and emission of these gases (Clemens, Trimborn, Weiland, & Amon, 2006). Nevertheless, an increase in CO 2 emissions after fertilization has been observed probably because of intensive decomposition of organic carbon after the application of easily degradable OM (Pezzolla et al, 2012) but emissions of GHG (such as CO 2 and CH 4 ) from fields fertilized with digestate on total emission from agriculture remain relatively low (Czubaszek & Wysocka‐Czubaszek, 2018).…”

Legacy effects override soil properties for CO₂ and N₂O but not CH₄ emissions following digestate application to soil

et al. 2020

The application of organic materials to soil can recycle nutrients and increase organic matter in agricultural lands. Digestate can be used as a nutrient source for crop production but it has also been shown to stimulate greenhouse gas (GHG) emissions from amended soils. While edaphic factors, such as soil texture and pH, have been shown to be strong determinants of soil GHG fluxes, the impact of the legacy of previous management practices is less well understood. Here we aim to investigate the impact of such legacy effects and to contrast them against soil properties to identify the key determinants of soil GHG fluxes following digestate application. Soil from an already established field experiment was used to set up a pot experiment, to evaluate N 2 O, CH 4 and CO 2 fluxes from cattle-slurry-digestate amended soils. The soil had been treated with farmyard manure, green manure or synthetic N-fertilizer, 18 months before the pot experiment was set up. Following homogenization and a preincubation stage, digestate was added at a concentration of 250 kg total N/ha eq. Soil GHG fluxes were then sampled over a 64 day period. The digestate stimulated emissions of the three GHGs compared to controls. The legacy of previous soil management was found to be a key determinant of CO 2 and N 2 O flux while edaphic variables did not have a significant effect across the range of variables included in this experiment. Conversely, edaphic variables, in particular texture, were the main determinant of CH 4 flux from soil following digestate application. Results demonstrate that edaphic factors and current soil management regime alone are not effective predictors of soil GHG flux response following digestate application. Knowledge of the site management in terms of organic amendments is required to make robust predictions of the likely soil GHG flux response following digestate application to soil.

“…Considering the CO 2eq quantity emitted into the atmosphere for synthetic fertilizers production, partial or total fertilization with digestate provided lower CO 2eq emissions [25]. Application of digestate had a relatively lower impact on the emissions of CO 2 and CH 4 compared to urea [56]. Cumulative N emissions via volatilization showed that digestate could be a promising method of sustainable fertilization management to decrease N losses [51].…”

Currently, little data are available on greenhouse gas (GHG) emissions from sweet sorghum production under temperate climate. Similarly, information on the effect of bio-based waste products use on the carbon (C) footprint of sorghum cultivation is rare in the literature. The aim of this study was to evaluate the agronomical and environmental effects of the application of biosolids as a nitrogen source in the production of sweet sorghum as a bioenergy crop. The yield of sorghum biomass was assessed and the GHG emissions arising from crop production were quantified. The present study focused on whether agricultural use of sewage sludge and digestate could be considered an option to improve the C footprint of sorghum production. Biosolids—sewage sludge and digestate—could be recognized as a nutrient substitute without crop yield losses. Nitrogen application had the greatest impact on the external GHG emissions and it was responsible for 54% of these emissions. CO2eq emissions decreased by 14 and 11%, respectively, when sewage sludge and digestate were applied. This fertilization practice represents a promising strategy for low C agriculture and could be recommended to provide sustainable sorghum production as a bioenergy crop to mitigate GHG emissions.
