IMPACT OF AN AMENDMENT FOR SOIL STRUCTURE IMPROVING ON SOIL AT SPRINKLING

abstract 1061502020 issue 106 pp. 313 – 323 28.02.2015 ru 885
The article presents the research results of the impact of amendment improving soil structure on soil upon sprinkler irrigation of agricultural lands. It is proposed to use artificial aggregation of soil for water erosion control via composition of structure-forming materials. The developed composition includes slagheap rock, bentonitic clay, claydite screenings, and shell limestone. Adjusted analytical relations of the impact of the amendment on runoff coefficient depending on the intensity of artificial rain upon irrigation of agricultural lands, slope, and water permeability have been revealed. Regression analysis of spectral surfaces has shown that slope of irrigation site has a significant impact on the increasing of runoff coefficient values, while correlation coefficient equals to 0.97. Water permeability has negative correlation, -0.85, with increasing the values of runoff coefficient. The relation between runoff coefficient and intensity of artificial rain is less strong, 0.89. We have determined that applying of the given amendment provides decreasing of runoff coefficient by 15 % depending on the slope of irrigation site, and by 20 % depending on rain intensity. Experts in the field of land reclamation can use obtained analytical relations for predicting surface soil loss when estimating the efficiency of amendment applying to control soil erosion activities at agricultural lands

SELECTING THE OPTIMAL COMPOSITION OF STRUCTURE-FORMING MATERIALS TO CONTROL IRRIGATION EROSION

abstract 0971403024 issue 97 pp. 334 – 348 31.03.2014 ru 1579
To control irrigation erosion, the artificial aggregation of soil by structure-forming materials was proposed in the article. The research was conducted for establishing the impact of the percent content of each fraction on soil cation exchange capacity
