Local behavior of fractional p-minimizers

Annales de l'Institut Henri Poincaré C, Analyse non linéaire, 2016
We extend the De Giorgi–Nash–Moser theory to nonlocal, possibly degenerate integro-differential operators.

Inorganic Phosphorus Transformation and Phosphorus Adsorption–Desorption Properties of Soil in a Cotton Field Under Mulched Drip Irrigation in Xinjiang: A Four-Year Field Assessment

Frontiers in Environmental Science, 2022
Phosphorus (P) fertilizer is generally applied to enhance the soil P pool and meet crop demand, but most of the added P is absorbed by soil. This study aimed to explore the importance of P fractions and adsorption–desorption characteristics on the demand

Quantifying phosphorus fertilizer distribution and the contribution of fertilizer and soil legacy phosphorus to phosphorus uptake by maize – A 32P‐labelling study

Food and Energy Security, 2023
The availability of phosphorus (P) fertilizer applied to soil can diminish rapidly because of the complex soil P immobilization processes. However, the quantitative distribution of fertilizer P in the soil P fractions is not fully understood.

Effects of long-term irrigation on soil phosphorus fractions and microbial communities in Populus euphratica plantations

Forestry Research, 2023
Irrigation has been demonstrated to be effective in managing Populus euphratica plantations, but its impacts on phosphorus (P) availability and the soil microbiome have not been fully elucidated.

Phosphorus fractions in leaves.

New Phytologist, 2022
Leaf phosphorus (P) comprises four major fractions; inorganic phosphate (Pi ), nucleic acids, phospholipids, P-containing metabolites and a residual fraction.

Transcendental p-adic continued fractions [PDF]

Mathematische Zeitschrift, 2017
We establish a new transcendence criterion of $p$-adic continued fractions which are called Ruban continued fractions. By this result, we give explicit transcendental Ruban continued fractions with bounded $p$-adic absolute value of partial quotients. This is $p$-adic analogy of Baker's result.

Regularity for a fractional p-Laplace equation [PDF]

Communications in Contemporary Mathematics, 2017
In this note, we consider regularity theory for a fractional [Formula: see text]-Laplace operator which arises in the complex interpolation of the Sobolev spaces, the [Formula: see text]-Laplacian. We obtain the natural analogue to the classical [Formula: see text]-Laplacian situation, namely [Formula: see text]-regularity for the homogeneous equation.

Sustainable phosphorus management through enriched compost and mineral fertilizers improves soil biological indicators and mustard productivity

Journal of Agriculture and Food Research
Agri-food and nutritional security are increasingly threatened by soil degradation and climate change, which accelerate nutrient depletion and limit sustainable agricultural productivity.

Potential Use of Rice Husk Biochar and Compost to Improve P Availability and Reduce GHG Emissions in Acid Sulfate Soil

Agronomy, 2020
Acid sulfate soil (ASS) has major problems related to phosphorus deficiency and high potential for N2O emissions, as well as strong acidity. The objective of this study was to evaluate the effects of rice husk biochar and compost on P availability and ...
