Structure Stability of Cultivated Soils from Semi-Arid Region

The Sustainable Development Goals of the United Nations call for applying soil management practices that contribute land degradation neutrality. Our objectives were to investigate the effect of (i) soil management¡ªconventional tillage (CT under crop) and no-tillage (NT under grass)¡ªand (ii) an amendment (polyacrylamide (PAM)) application on the structure stability indices of soils from a

Improving aggregate stability and hydraulic properties of Sandy loam

This study aims to evaluate the effect of applying two types of anionic polyacrylamide polymers (PAMs) with different molecular weights on: (1) soil aggregate stability, (2) infiltration rate and (3) saturated hydraulic conductivity of sandy loam soil and introduce a novel modelling approach to predict the effect of PAM addition on the mentioned...

polyacrylamide characteristics related to soil applications

POLYACRYLAMIDE CHARACTERISTICS RELATED TO SOIL APPLICATIONS

Water soluble polyacrylamides (PAMs) have been proposed as soil amendments for various agricultural purposes. Recent interest has centered on very high molecular weight (10¨C20 g mol?1), low to moderate charge (10¨C20 mol %) anionic materials, added to irrigation water to prevent silt loss from irrigated fields. These PAMs are within a broad spectrum of commercially available compounds

Effects of anionic polyacrylamide on maize growth: a short term

Being the most popular polymeric conditioners, the anionic polyacrylamide polymers (PAMs) are water-soluble, have high molecular weight and low toxicity, with their moderate negative-charged chains stabilize soil aggregates by flocculating clay particles (Sojka et al. 2007 ).

Biodegradation of anionic polyacrylamide by manganese

Abstract Manganese peroxidase (Mn P) is capable of effectively degrading anionic polyacrylamide (HPAM). However, the interaction of Mn P with HPAM at molecular level is lacking until now. Here, the HPAM model compounds, HPAM-2, HPAM-3, HPAM-4, and HPAM-5, were selected to reveal their binding mechanisms with Mn P.

STABILITY ANALYSIS OF SOIL AGGREGATES TREATED WITH ANIONIC

Soil sealing and erosion on agricultural fields is a severe problem that often leads to increased runoff and decreased soil quality. Much research has been conducted using polyacrylamide (PAM) to control soil sealing and reduce erosion, yet few studies have attempted to determine the most effective molecular formulation(s) of PAM. Our objective was to examine the ability of a range of PAM
