From: Improving water retention capacity of an aeolian sandy soil with feldspathic sandstone
Water availability parameters of aeolian sandy soil modified by feldspathic sandstone and at different mass ratios (CK = 0:1, control; T1 = 1:5; T2 = 1:2; and T3 = 1:1). Values are the mean ± standard deviation (n = 3). For each parameter, different lowercase letters indicate a significant difference between means at P < 0.05.
