Effect of fertilizers on the water-physical properties of soils for winter wheat

We have studied the effect of soil treatment and fertilizer doses for winter wheat on the density and overall porosity of the soil. Samples of soils were taken from soil layers 0-10, 10-20 and 20-30 cm in succession in the phases of tilling of winter wheat, tubing and full ripeness. Depending on soil treatments and fertilizer rates, there were regular changes in the indices of natural humidity, soil density and total porosity in the soil layers under study. At the end of vegetation, in all variants and phases of development, an increase in the density of soils, moisture, and a decrease in porosity were observed. On the soil layers it should be noted that in the 0-10 cm layer the soil moisture and density were low, as they moved down the profile they increased, a total porosity - on the contrary, in the upper 0-10 cm layer - high, and down the profile - decreased.
