ABSTRACT
Objective: The
aim of this study is to determine the effects of liquated humic substance,
polyacrylamide and polyvinylalcohol on runoff and soil losses by using a
laboratory type rain simulator.
Material
and Methods: In this study, the 7 cm coarse gravel was placement
into the erosion pan, which sized 30x45x15 cm, sloped of 9 %. After laying a
permeable clothe on the coarse gravel layer, soil samples which were thought to
the 8 mm sieve, were placement into the erosion pan. Liquated humic substance, PAM and PVA solutions (0, 1, 2 and 4
ml l-1; 100 ml) were sprayed uniformly on soil surface by a hand
type pump with 2 replicated. 40 mm h-1 of artificial rainfall was
applied during 1 hour by a laboratory type rainfall simulator. The runoff start
time is measured with a stopwatch. Runoff and soil losses were calculated and
tabulated.
Results:
In this study, liquated humic substance, PAM and PVA
treatments decreased runoff and soil loss significant levels.
Conclusions:
Runoff and soil loss were decreased by using these
soulutions Therefore, liquated humic substance, PAM and PVA solusions can be
use reducing the erosion easily.
