effect of polyacrylamide integrated with other soil

for example, adimssu et al. reported a 28% and 47% reduction of annual runoff and soil loss, respectively, due to the use of graded soil bunds on the galessa micro-watershed, in the central high-lands of ethiopia, and amare et al found that soil bunds combined with elephant grass reduces runoff by 40% and soil loss by 63% from debre mewi

examining the impact of polyacrylamide and other soil,this study aims to investigate the effects of polyacrylamide (pam) alone or integrated with other soil amendments on soil fertility and teff (eragrostis tef (zucc.) trotter) yield. a field experiment was carried out for 2 years in three contrasting agroecological zones of the upper blue nile basin, ethiopia, using a randomized complete block design with 3 replicates. the amendments applied

effect of soil amendments on soil respiration in the midlflocculant

the effects of soil amendments on soil respiration (sr) rate have not yet been fully evaluated. in the upper blue nile basin, ethiopia, we investigated seasonal variations in sr rates between and within soil amendments. we set up 24 plots with 8 treatments—polyacrylamide (pam), gypsum (g), biochar (b), lime (l), control (c), pam + l, pam + g, and pam + b—in 3 replicates. soil temperature

polyacrylamide (pam) prices wholesale flocculant,the pam has been traded at cheaper rates to clear off the oversupplies. thus, polyacrylamide anionic grade fob qingdao was assessed at usd 1540 per tonne in q3-end. europe. prices of polyacrylamide have continued their bearish rally in the european market during the third quarter of 2022, bolstered by the weak feedstock acrylamide prices.

dual benefits of polyacrylamide and other soil amendments

polyacrylamide (pam) mitigates soil nutrients depletion and increases nutrient utilization, however, the effect of pam combined with other amendments were not tested at field condition. objective of the study was, therefore, to identify the best combination of amendments that can improve soil nitrogen (n) and phosphorus (p) balances while

What is hydrolyzed polyacrylamide (HPAM)?
Hydrolyzed polyacrylamide (HPAM), a derivative resulting from the hydrolysis of PAM, demonstrates significant thickening capabilities in freshwater and at relatively lower temperatures (75 °C) due to strong intra- and inter-chain electrostatic repulsion of carboxylate groups 14.
Can polyacrylamide improve hydrocarbon production efficiency?
Provided by the Springer Nature SharedIt content-sharing initiative Polyacrylamide (PAM) and its derivatives play a pivotal role in various facets of hydrocarbon development. Proper application and treatment of PAM have the potential to enhance hydrocarbon production efficiency while mitigating adverse environmental effects.
Why is polyacrylamide hydrogel hard to enhance through coordination bonds?
Cite this: ACS Appl. Mater. Interfaces 2024, 16, 24, 31555–31566 Polyacrylamide (PAM) hydrogel is hard to enhance through coordination bonds because amide groups rarely coordinate with metal ions strongly in an aqueous solution. It is known that the aqueous solution of ZrOCl 2 .8H 2 O can be strongly acidic depending on its concentration.
