Short-Term Phosphorus Fertilization Alters Soil Fungal Community in Long-Term Phosphorus-Deprived Yellow Soil Paddy Fields

open access: yesAgriculture
Phosphorus (P) in soil is important in the process by which soil microbial communities regulate soil enzyme activity. We aim to explore how short-term P fertilization affects the composition and functionality of the soil fungal community, offering ...

Nanocrystalline Cellulose from the Solitary Tunicate Phallusia Mammillata, a Valuable Nanocellulose Precursor

open access: yesAdvanced Sustainable Systems, EarlyView.
This study explores the potential of locally harvested Phallusia mammillata, a tunicate usually discarded as waste from mussles farming as a viable source for producing various high‐grade cellulose derivatives in the form of nanofibrils (NFC) and nanocrystals (CNC). Abstract Ascidians are ubiquitous filter‐feeding marine invertebrates, the only animals

Practical fertilization in maize with organic fertilizers

open access: yesPractice Abstract, 2018
Maize is one of the most important crops, especially on dairy farms. Because dairy farms are so nutrient-rich, they are often associated with nitrate leaching. To avoid N leaching during the winter period, the implementation of catch crops is important. Together with root fertilization and organic fertilizers, nitrogen can be used very efficiently and

Sustainable Flame‐Retardant Poly Lactic Acid Biocomposites Reinforced with Polyphosphate‐Enriched Microalgae: Unlocking the Potential of Hyper‐Compensation

open access: yesAdvanced Sustainable Systems, EarlyView.
This study explores microalgae cultivation for wastewater treatment and enhancement of poly lactic acid (PLA)‐based biocomposites. It achieves up to 99.9% nutrient removal, increases biomass productivity by 322%, and demonstrates a triphasic luxury phosphorus uptake system. Incorporation into PLA improves fire‐retardant properties, suggesting potential

Herbicide Applications Reduce Gaseous N Losses: A Field Study of Three Consecutive Wheat–Maize Rotation Cycles in the North China Plain

open access: yesAgronomy
Herbicide residues in farmland soils have attracted a great deal of attention in recent decades. Their accumulation potentially decreases the activity of microbes and related enzymes, as well as disturbs the nitrogen cycle in farmland soils.
