Evaluating the effect of phytoameliorative measures on the land reclamation status

Abstract

This article presents the results of improving the land ameliorative condition of lands as a result of growing phytoameliorating plants as a secondary crop in conditions of water shortage. There is a scientific research aimed at saving water resources used for salt washing. White sorghum (Sorghum Vulganell pers) and mung bean (Phaselus aureus Piper) were planted as phytoameliorating crops and compared with uncultivated fields. During the experiments, when the effect of phytoameliorating crops on the number of chlorine ions contained in the soil was studied, initially, at the beginning of the vegetation period, the number of chlorine ions in the soil tillage layer (0–30 cm) increased by 0.015%. At the end of the experiments, the number of chlorine ions in the tillage layer (0–100 cm) was 0.012%. Chlorine ion content in the sorghum (Sorghum Vulganell pers) was 0.033% in the driving layer (0–30 cm) and 0.029% in the 0–100 cm layer, while chlorine ion content in the soil was 0.036 and 0.032% in the moss (Phaselus aureus Piper). In addition, the highest saline leaching rate in the experimental field was 5383 cbm/ha in the plowed field. And the seasonal salinity leaching rate was 2380 cbm/ha when sowing white corn (Sorghum Vulganell pers) as a phytoameliorant, and when sowing moss (Phaselus aureus Piper), 3403 cbm/ha. This is 37–56% less than the control or 1980–3003 cbm/ha.
