The effect of organic wastes on the horizontal and vertical wetting distance in soil

Abstract

The growing world population has made establishing new agricultural areas and increasing the fertility of current areas ncccssaiy. In terms of yield and productivity, sandy soils are generally poor in terms of crop production and require good management in terms of plant production. Due to their large pores, they possess high water conduction capacities, however their water holding capacity is low. Water movement in these soils is formed as a result of directing by gravity and adhesive forces. The aim of tliis study was to determine the effect of walnut shell biochar(WS), farm manure (FM) and worm manure (VC) on the water movement in the horizontal and vertical direction in the soil. Soil was mixed with soil organic matter (SOM) at different doses (0%, 1%, 2%, 4% or 8%). Following the incubation period, water movement was observed in the soil irrigated with a constant debit. As a result of the research, it was determined that FM and VC applications increased the wetting distances in horizontal direction. In addition, increased doses of SOM increased the horizontal wetting distance (p<0.001). Similarly, increased doses of SOM were determined to decrease the wetting distance in the vertical direction. © 2019 Parlar Scientific Publications. All rights reserved.
