The conversion of forests to agricultural croplands significantly depletes soil organic carbon reserves, total nitrogen, and available potassium, reaching critical thresholds in the Peruvian Amazon

Frontiers in Soil Science
IntroductionLand-use change from primary forests to agricultural croplands can degrade soil quality by depleting soil organic carbon (SOC), total nitrogen (STN), and soil-available potassium (SAK).

Optimized Chemical Analysis of Cow’s Milk Proteins: Evaluation of New Measuring Devices

Indonesian Journal of Chemistry, 2022
The demands of quality and choice in the dairy industry require analysis of extended performance. Ancient milk protein measuring devices take a long time and provide slow and inaccurate results.

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

Impacts and fate of experimentally enhanced nitrogen deposition on a British lowland heath

, 1998
Between 1989 and 1996, nitrogen, in the form of (NH4)2SO4 (7.7 or 15.4 kg ha-1 year-1), was added to experimental plots of Calluna at a lowland dry heath in the south of England. Background deposition at this site was estimated at between 13-18 kg N ha-1

Combination of Warming and Vegetation Composition Change Strengthens the Environmental Controls on N₂O Fluxes in a Boreal Peatland

Atmosphere, 2018
Climate warming and vegetation composition change are expected to influence greenhouse gas emissions from boreal peatlands. However, the interactive effects of warming and different vegetation compositions on N2O dynamics are poorly known, although N2O ...

The soil microbial hydrolytic activity, content of nitrogen and organic carbon were enhanced by organic farming management using cover crops and composts in potato cultivation

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2020
Nowadays, in sustainable agriculture growing winter cover crops and using organic manure have been widely implemented to improve soil quality which leads to increase of microbial activity.

Prognosis of Long‐Term Continuous Renal Replacement Therapy and the Impact of Combined Continuous Intravenous Sodium Infusion Therapy

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Patients requiring long‐term continuous renal replacement therapy (CRRT) generally have poor prognoses. This study evaluated whether adding continuous intravenous sodium infusion (cIVNa) is associated with improved hemodynamics and outcomes in patients undergoing long‐term CRRT for ≥ 7 days.

Incidental phosphorus and nitrogen loss from grassland plots receiving chemically amended dairy cattle slurry

, 2012
peer-reviewedChemical amendment of dairy cattle slurry has been shown to effectively reduce incidental phosphorus (P) losses in runoff; however, the effects of amendments on incidental nitrogen (N) losses are not as well documented. This study examined P

Sources of nitrogen for winter wheat in organic cropping systems [PDF]

, 2013
In organic cropping systems, legumes, cover crops, residue incorporation, and manure application are used to maintain soil fertility, but the contributions of these management practices to soil nitrogen (N) supply remain obscure.

Effects of Organic–Inorganic Nitrogen Deposition on Element Content and Stoichiometric Ratios in the Rhizospheric Soil of Torreya grandis

Horticulturae
The deposition of atmospheric nitrogen (N) includes organic N (ON) and inorganic N (IN). The effect of varying ON:IN ratios on the elemental composition in the root zone of T. grandis remains poorly understood.
