The changes of the physical properties in the soil under the influence phosphogypsum and manure

The changes of the basic physical properties agrochernozem in condition of field experience in making different doses of phosphogypsum and gobbler manure was studied. It was shown that the increased water-holding capacity in the experimental variants with using mixed phosphogypsum and gobbler manure, in the variants with using only phosphogypsum the water-holding capacity was decreased compared to the control variant. In all variants the experience was improved structural-aggregate composition (due to the reduction of large lump aggregates), increases their water resistance, reduced compaction, however, increases the salt content that was diagnosed decrease in the level of electrical resistivity. The maximum change in the physical properties indicated in the variants with the using of mixed phosphogypsum and gobbler manure at a dose of 60 t/ha in the ratio of 1:2.
