Abstract

Background and objectives:
Anionic polyacrylamide application as an organic conditioner alone or in combination with organic material, can improve soil properties. The objective of this study was to investigate the influence some organic conditioners on mean weight diameter (MWD) and dispersible clay percentage (DCP).
Materials and methods:
Soil samples collected from the top 30-cm layer of two loamy sand and clay soils were treated with alfalfa and wheat residues (
