Analysis of different selenium levels influence on leaf area index (LAI), hectare yield and selenium content in potato tubers

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008
In this work are described results of field trials in years 2006 and 2007. In these small plot trials we observed an influence of different selenium levels (control; 12, 24, 48 and 72 kg Se . ha−1 to the soil; 200 and 400 g Se .

Evaluating the sensitivity and influential factors of freeze-thaw erosion in Tibet, China

open access: yesFrontiers in Earth Science, 2022
Freeze‒thaw (FT) erosion has gradually become more severe due to climate warming, and concerns about FT erosion in ecologically fragile areas (e.g., high-altitude and high-latitude areas) continues to grow.

Mulching and soil tillage influence on the thermal behaviour of a Luvisol surface layer [PDF]

open access: yes, 2009
Important energy exchanges at soil surface regulate the thermal environment within top soil layer and the boundary layer above it. By this reason, the application of mulches or the modelling of micro relief by soil tillage are common practises to modify ...

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Effects of atrazine application on soil aggregates, soil organic carbon and glomalin-related soil protein

open access: yesPlant, Soil and Environment, 2021
Atrazine is still widely used in China. Atrazine residue (1.86-1 100 mg/kg) in the soil has exceeded the allowable limit (1.0 mg/kg), affecting soil structure and soil aggregate composition.

Thirty years of growing cereal without P and K fertilization [PDF]

open access: yes, 2008
Over thirty years a significant depletion of P and K in soil occured when the were not given in fertilizers. This caused a reduction in crop yield. An abundant P application exceeding the crop uptake very clearly prevented the yield reduction but did not

Effect of soil applied zinc sulphate on wheat (Triticum aestivum L.) grown on a calcareous soil in Pakistan [PDF]

open access: yes, 2008
A field experiment was conducted to investigate the effect of soil application of zinc fertilizer on yield and yield components of wheat (Triticum aestivum L. cv. Inqlab 91) grown on calcareous soil in Pakistan.

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

open access: yesFEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Effect of Humisol on survival and growth of nursery grafted walnut (Juglans regia L.) plants

open access: yesHorticultural Science, 2013
The effect of Humisol organic fertiliser (150 g humic acid/l + 20 g/l mineral nutrients) on plant survival and growth of five walnut cultivars grown over a period of two years in the nursery were evaluated. Walnut plants treated with Humisol at the total

Application of Jute Fiber in Soil Stabilization

open access: yesSustainability, Agri, Food and Environmental Research-DISCONTINUED, 2020
Abstract: This paper is focusing on the stabilisation of soil using jute fibre as soil stabilizer. Stabilisation is the process of modifying the properties of a soil to improve its engineering performance and used it for a variety of engineering works.
