Sugarcane is one of the main agro-industrial products consumed worldwide, and, therefore, use suitable soils a key factor to maximize its production. As result, need evaluate soil matrices, including many physical, chemical, and biological parameters, determine soil’s aptitude for growing food crops increases. Machine learning techniques were used perform an in-depth analysis physicochemical in...

Abstract The quality of the Colli Albani volcanic soils has certainly contributed to vine cultivars hence name one oldest wines (i.e., Alban wine). alkali up 15 wt%, SiO2 ≤ 52 wt% and emplacement at high temperature (≤ 600 °C) are bedrock features that have deeply influenced soil-forming processes in vineyards. However, peculiar not well known. Field survey textural, mineralogical, chemical dat...

What are Cation Exchange and Cation Exchange Capacity? Soil clay minerals and organic matter tend to be negatively charged, thus attracting positively charged ions (cations) on their surfaces by electrostatic forces. As a result, the cations remain within the soil root zone and are not easily lost through leaching. The adsorbed cations may easily exchange with other cations in the soil solution...

sustainable exploitation of land resources is directly affected by considering soil quality which finally will also conclude environmental protection. therefore, assessing different soil quality aspects which are sensitive to various land management practices seems too important. in this study, some selected soil quality indicators have been compared in five land use systems including untouched...

Using genetic and biochemical approaches, we investigated proteins that regulate macrophage cholesterol efflux capacity (CEC) and ABCA1-specific CEC (ABCA1 CEC), 2 functional assays that predict cardiovascular disease (CVD). Macrophage CEC and the concentration of HDL particles were markedly reduced in mice deficient in apolipoprotein A-I (APOA1) or apolipoprotein E (APOE) but not apolipoprotei...

This study examines the effects of land use and slope aspect on soil erodibility (K-factor) fractal dimension (D) particle size distribution (PSD) in calcareous soils at watershed scale western Iran. The analyzed 113 samples collected from four uses (slope-farmland, farmland, pasture, woodland) a depth 0–20 cm, measuring common properties such as texture, organic matter (SOM), calcium carbonate...

Phosphorus (P) fractionation is the validation of nature, solubility and relative bioavailability P. A sequential P extraction was used to determine distribution plant-available fractions in soils. The relationships these soil properties foliar contents were also determined. Results this study showed substantial differences among orchards. Higher amounts organic matter (SOM), cation exchange ca...

Abstract A study for the physicochemical properties was carried out in agricultural soils ( n = 489) on flat and piedmont areas of Valle del Cauca. The degradation level different studied by determining analyzing their properties. Variability distribution analysis, central tendency, dispersion multivariate analysis were included. results showed that saturated hydraulic conductivity (Ks) electri...

Agricultural land is that can affect agricultural productivity. Land, which part of resources, the main component in production commodities. In supporting productivity commodities, there must be sufficient nutrients soil. Tabundung sub-regency a producer food crops, livestock and fisheries. As sector, crops not proportional to total area harvested land, meaning optimal if it based on area. The ...

A study was conducted at Kalamandari Tanda-1 micro-watershed, Karnataka, India, to assess the spatio-temporal variability of surface soil properties sampled from 23 varied soil-phase units, delineated using IRS P6 LISS-IV merged Cartosat-I imagery (2.5 m spatial resolution). Three sets samples (231 in each set) were collected, analyzed, and interpolated evaluate variability. Further soil-phase-...
