This study aimed to determine the distribution, stability, and soil organic carbon (SOC) of aggregates, contribution aggregate proportion, stability index, aggregate-associated SOC total SOC. Three hundred sixty samples were gathered from shelterbelts neighboring farmlands in five layers 1 m profiles Songnen Plain, northeastern China. The shelterbelt plantations found increase by 69.5% 103.8% &...

Soil erosion and surface pollution near reservoirs can adversely affect water quality safety. aggregate stability is an important predictor of soil loss resistance that strongly influenced by land use. This study therefore aimed to identify factors affecting provide empirical theoretical insights could guide the development management measures increase quality, optimize use, maximize sustainabi...

this study was conducted to investigate the effect of soil moisture content in primary tillage and travel speed during disking operation on the performance of an offset disk harrow in a silty clay loam soil. at first, the effect of three soil moisture content ranges of (12-14), (14-16) and (16-18) percent (dry basis) on soil clod size (left from moldboard plowing) was investigated. then, the pe...

A two part study utilizing polyoxymethylene (POM) was undertaken to investigate a three stage process (Melt-Extrusion/Annealing/Uniaxial-Stretching) (MEAUS) employed to produce microporous films. In this first part, three POM resins (D, E & F) were melt-extruded into tubular films (blowup ratio; BUR = 1), where resin D has a higher weight average molecular weight (Mw) than resin E but both poss...

Soil is a highly significant resource for human survival, and agglomerates, as the basic unit of soil structure, not only enhance fertility control biological validity nutrients but also strengthen soil’s erosion resistance. The mass application fertilizers may significantly affect crop growth rational dispensing will be an urgent issue to addressed. Therefore, effect fertilizer on stability wa...

This work is concerned with the approximate solution of the problem generated by the integral of first kind relating the shear relaxation modulus of entangled, linear and flexible homopolymer blends and the molecular weight distribution (MWD). Procedures are proposed to estimate the density distribution function (DDF) of the MWD from numerical solutions of the theoretical model composed by the ...

Soil mulching is one of the common measures applied in organic agricultural production which could replace plastic films and protect environment. In order to fully evaluate effects different straw thicknesses on soil health, maize was mulched with 0 cm (CK), 2 cm, 4 6 surface assess temperature (ST) moisture (SM), pH, carbon (SOC), total nitrogen (TN), C/N, aggregates bulk density (SBD) a tempe...

BACKGROUND It is important to include large sample sizes and different factors that influence the six-minute walking distance (6MWD) in order to propose reference equations for the six-minute walking test (6 MWT). OBJECTIVE To evaluate the influence of anthropometric, demographic, and physiologic variables on the 6 MWD of healthy subjects from different regions of Brazil to establish a refere...

An in-home beef study evaluated consumer ratings of clod steaks (n = 1,264) as influenced by USDA quality grade (Top Choice, Low Choice, High Select, and Low Select), city (Chicago and Philadelphia), consumer segment (Beef Loyals, who are heavy consumers of beef; Budget Rotators, who are cost-driven and split meat consumption between beef and chicken; and Variety Rotators, who have higher incom...
