Phytomeliorative effect of safflower on agrophysical indicators of dark chestnut soils.

Soil layer (cm)	Density (g/cm^3)			Soil structure (%)
	Spring	Autumn	Difference	Spring	Autumn	Difference
0–10	1.31	1.30	+0.010	63.26	64.11	+0.85
10–20	1.29	1.27	+0.020	64.00	64.75	+0.75
0–20	1.30	1.29	+0.010	63.63	64.43	+0.80

In assessing the phytomeliorative role, the influence of safflower on the biological activity of dark chestnut soils is of great importance.
