Zeolite bearing deposits were characterized in Banyas region using sample A
(which is a powdered mixture taken from five tuff and tuffite levels) compared with
sample B (which is taken from Basatin Al-Assad site within the studied region).
XRD met
hod showed several zeolite phases in addition to non-zeolite minerals
and volcanic glass. FTIR method revealed a general feature of zeolite groups. DTA
method showed a range within zeolite structure stability. Specific surface area was
measured using BET method giving the value 87m2/g. The range of pore volume
distribution was also calculated with ~40Ǻ, and intermediate pore diameter of ~23Ǻ.
XRD study of the standard sample (B) showed slightly different zeolite phases
from A. FTIR measurement showed same results as in A. DTA plots revealed a high
stability of sample B, SBET of 61m2/g, VP around 40Ǻ and r- at ~25Ǻ.
The research was carried out at Al-Qamishli Agricultural Research Center, GSAR,
Syira, during the seasons 2011, 2012 and 2013, in order to estimate the effect of
adding different levels of a crude Zeolite (T2-20 tons/ha, T3- 40 tons/ha, in addition
to the control (without adding Zeolite T1), on wheat productivity within a bilateral
crop rotation was followed, consisted of wheat and chickpea, and on the content of
nitrogen, phosphorus and potassium in the surface layer of the soil .The research
was conducted using Complete Randomized Block Design with three replicates.
The research was conducted at the poultry farm in Kharabo, Faculty of
Agriculture, Damascus University. 1080 chicks of Lohman hybrid, one day old,
distributed randomly and equally into six different groups, G1….G6 (180
chicks/ group) with three re
plicates in each group (60 chicks per replicate).
Chicks in all groups were fattened for 42 days on Diets composed of vegetarian
feeding stuffs, based on corn, soya bean meal and different additives. Chicks of
G1 were fed on the main diet without adding iron or copper. The chicks in G2
and G3 were fed on the main diet mixed with 80 and 160 ppm of iron
respectively. The vhicks of G4 were also fed on the main diet mixed with 8 ppm
of copper. The Chicks of G5 and G6 were fed on the main diet mixed with iron
and copper (80 and 8 ppm) and (160 and 8 ppm), respectively. Results
demonstrated that adding iron and/or copper to the broiler diet was safe for
chickens up to 42 days of age and did not affect significantly on carcass
parameters. Supplementation of broiler diet with 8 ppm of copper was not
associated with accumulation of copper in the tissues of liver, leg bone, breast,
and thigh. Adding 80-160 ppm of iron to the broiler diets was not associated
with high level of accumulation of iron in the tissues of breast and thigh but
with high concentrations (p < 0.05) in the tissues of liver and leg bone.
The study was taken place at the experimental station (kharabo), Faculty of
Agriculture, Damascus University, 1464 - one day old chicks of the hybrid
Lohmann were used to determine the effect of adding different levels of
methionine without or wit
h lysine on some of carcass traits. Chicks were
divided randomly and equally into 8 groups (183 each) at the first day with 3
replicates for every group (61 each).
This research is done in an experiment by plaster in the
circumstances of Homs. The aim of this paper to study the effect of
adding four different levels of phosphogypsum as much as (0.00,
6.72, 13.44, 20.16)ton / hectare (three replicates for eac
h treatment)
on bulk density and structure stability for clay soil has taken from
(Kattina).
The results showed improvement in the stability of the structure of
soil specially (0.25-1)mm, increasing in aggregation degree ,
increasing of the rate of total porosity ,air filled porosity in
comparison to the control at the two levels(13.44, 20.16)ton/hectare
and also by increasing the added level . Whereas the dispersion
ratio , and Bulk density were decreased when increasing the level
of phosphogypsum at the same two levels.
The main achieved results in this study showed , a significant
increase in aggregation degree in the soil when increasing the ratio
of the added phosphogypsum at the levels( 6.72, 13.44, 20.16) in
comparasion with control .
In other way the dispersion ratio was decreased and had negative
relationship when increasing the level of the added
phosphogypsum in comparasion with control .
