Abstract
Samples were collected from the three sites: Sendafa, Debte
Ilerhan and Fiche to study changes induced by "Guie" practice. 'l'he
chemical and physical changes as well as the growth of barley in
these soils was compared for the three sites.
The laboratory study involved the determinations for particle
size distribution, the ignition experiment, the determination for
changes in orga~ic carbon, total nitrogen, available phosphorous, pH,
eleotrical conductivity, carbonates, the exchangeable c~tions, the
cation exchange capacity properties of the soils.' Plant analysis
for percent nitl'ogen and percent phosphorous was determined for
barley grown in the greenhouse experiment.
In the Greenhouse experiment the height of barley plants was
recorded as well as the counts on emergence, heading and fresh and
dry weights and weed score was done to evaluate the differences
between the three sites.
The results from the laboratory and greenhouse studies showed
similar variations among the treatments of the three sites. 'rhe
interior heap layers exposed to high temperatures both the negative
and positive effeots from "Guie" practice. The main positive effects
were found to be the increase in available phosphorous and the change
from find to sand sized particles. In contrast the main negative
effects were found to be the losses in organic carbon and total
nitrogen.
The growth study in the greenhouse experiment also showed variations
only among the treatments. The best growth was found to be in
the mixed treatment where optimum condition was a.ttained by mixing
all the different Guie affec ted and unaffec ted soils .•
