Biosolids towards Back-To-Earth alternative concept (BEA) for environmental sustainability: a review

Ramesh Poornima et al.

Summary: Biosolids are a nutrient-rich stable substance obtained during wastewater treatment process that can be used as a soil amendment to reduce the use of chemical fertilizers. Depending on the treatment process, biosolids characteristics can be optimized for sustainable waste management by recycling nutrients. They serve as a key tool for farm utilization by improving soil health and promoting plant growth.

Enhanced soil potential N2O emissions by land-use change are linked to AOB-amoA and nirK gene abundances and denitrifying enzyme activity in subtropics

Haikuo Zhang et al.

Summary: Converting natural forests to tea plantations in subtropical China directly increases soil inorganic nitrogen concentration, leading to increased nitrous oxide (N2O) emissions. This study also found that the increase in denitrifying enzyme activity and nirS + nirK gene abundance directly regulated N2O emissions, while the effects of AOB-amoA gene abundance and inorganic nitrogen concentration on N2O emissions were indirect.

Elevational shifts in foliar-soil δ15N in the Hengduan Mountains and different potential mechanisms

Qiong Chen et al.

Summary: This study investigated the determinants of foliar-soil delta N-15 and N transportation rates at different elevations in the Hengduan Mountains. The results showed that vegetation N limitation was stronger at medium high elevations due to higher microbial immobilization and shifts in vegetation preference. Surprisingly, soil delta N-15 was not strongly correlated with foliar delta N-15, indicating that litter input may not be the main driver of soil delta N-15. Instead, soil nitrification and denitrification played a more significant role in shaping the pattern of soil delta N-15 along the elevational gradient.

A global meta-analysis of crop yield and agricultural greenhouse gas emissions under nitrogen fertilizer application

Chan Guo et al.

Summary: The study collected 174 studies from 16 countries to determine appropriate nitrogen fertilization rates for enhancing crop yield while reducing greenhouse gas emissions. Results showed positive effects on crop yield and negative effects on greenhouse gas intensity, with recommendations for specific application strategies in different regions.

Evaluating land application of pulp and paper mill sludge: A review

Tomi Turner et al.

Summary: Over 400 million tonnes of board and paper are produced globally each year, generating 4.3-40 kg of sludge-like material, known as pulp and paper mill sludge (PPMS), per tonne of product. PPMS, with its high organic content and low toxicity, is being increasingly used as a soil amendment in agriculture. This review explores the benefits, potential impacts, and viability of land spreading PPMS, suggesting that risks can be mitigated and that the practice is environmentally responsible. However, further research is needed to assess long-term implications and the presence of emerging contaminants.

Nitrogen and phosphorus release from paper mill biosolids as affected by material source and soil type under controlled incubation

Bernard Gagnon et al.

Summary: The study compared the nitrogen and phosphorus release of four different sources of paper mill biosolids (PB) and de-inking paper sludge (DPS) in different soil conditions. The release of nitrogen and phosphorus varied depending on the source of PB and the type of soil, with mineral N addition possibly promoting N release in PB.

Pulp and paper mill sludges decrease soil erodibility

Kimmo Rasa et al.

Summary: The study demonstrated that organic sludges from the pulp and paper industry can improve soil fertility and reduce erosion in agricultural soils. Although the application of these organic amendments had minimal effects on cereal yield and quality, it significantly altered the fungal and bacterial composition in the soil. Additionally, the amendments were effective in reducing suspended solids and total phosphorus concentrations in percolation water, even four years after application.

Water availability regulates tree mixture effects on total and heterotrophic soil respiration: A three-year field experiment

Xinli Chen et al.

Summary: The study showed that planting a mixture of tree species in boreal forests can increase soil respiration rates, particularly under increased water availability. Soil respiration rates decreased with higher soil fungal to bacterial ratios, while the ratio of heterotrophic respiration to total respiration increased.

Urea treatment decouples intrinsic pH control over N2O emissions in soils

Md Sainur Samad et al.

Summary: The study found that pH was not a significant regulator of N2O emissions in urine-amended soils. Instead, new variables emerged as regulators of N2O emissions in such soils, likely due to the unique environment created. The study also showed a linear correlation between the emission ratio of N2O and the rate of N-gas loss, as well as associations between O2 consumption and AOB in urine-affected soils.

Differential response of soil CO2, CH4, and N2O emissions to edaphic properties and microbial attributes following afforestation in central China

Qiong Chen et al.

Summary: Land use change has a significant impact on soil CO2, CH4, and N2O emissions, with afforested lands showing higher CO2 and N2O emissions compared to abandoned land. The emission of CO2 is positively related to microbial activities, while CH4 uptake is correlated with soil environments and chemical properties. N2O emission is associated with nitrifying genes but negatively correlated with denitrifying genes.
