| Effect of synthetic and natural water absorbing soil amendments on plant growth and soil chemical properties of potato production was investigated in a field experiment in a semi-arid region in northern China in 2010-2012. Treatments included two different synthetic water absorbing amendments (potassium polyacrylate-PAA, polyacrylamide-PAM) and one natural amendment (humic acid-HA), both as single amendments, and combined amendments (natural combined with a synthetic) and a no amendment control. Soil amendment showed a significant (P ≤0.05) effect on plant height, stem diameter and leaf area index in the potato growing period in all three years, and improved the plant parameters respectively by 0.49%-36.90%, 2.59%-21.12% and 1.85%-37.57%.
