Short-Term Effects of Land Leveling on Irrigation-Related Some Soil Properties in a Clay Loam Soil

Table 2

The effects of land leveling on the sample variances of some selected soil properties from both 0–20 cm (surface soil) and 20–40 cm (subsurface soil). Asterisks next to postleveling variance values represent significant differences in the sample variances of pre- and postleveling soil properties caused by land leveling. The asterisks were obtained after employing Levene’s test (𝑛=30).
