This research was conducted in Lattakia province during the year 2012 first, to
identify the current status of the production residues and agro-processing materials in the
province and, second, to introduce modern methods of taking advantage of the
m and
raising their nutritional value.
Results showed that, the most agricultural residues are not optimally used, instead,
they were disposed and accumulated causing substantial losses and environmental
pollution.
Results showed that, the investment average ratio of legume, vegetables, cereals, and
fruit trees were 75%, 65%, 60% and 40% consensually
This research conclusion shows that, the optimal use of barley residue is a source of
cheap protein units that are necessary for animals feeds; where the cost per unit of digested
protein resulting from urea treated hays amounts to 0.5 S.Y.P. This amount represents one
fifth of the cost of protein unit from barley.
Also, the use of wheat straw in the cultivation of oyster mushrooms achieve
significant economic results, the net profit resulting from the cultivation area of 10 m2 of
oyster mushrooms using 30 kg of wheat straw was about 81000 S.P.
In addition to that, the research results show the importance of agricultural waste in
biogas production and the resulting compost, which in turn has achieved excellent results
when fertilizing crops with it. The increase in the yield of maize, wheat, faba bean and
vegetables were 35.7%, 12.5%. 6.6% and 14.1-20.6% consensually.
The reasearch was carried out during 2009 – 2010 in Al – Hasaka – Amoda - to study
the effect of cattle manure at the rat of 30 ton / ha , and four organic green manure ( Lentil,
Vetch, Faba bean and Barely) on soil content of organic matter and so
me mineral elements
compared with chemical fertilizer 400 kg / ha urea , 83 kg / ha P2O5 and 25 kg / ha K2O .
The manure significantly increased organic matter , phosphorus and potassium
concentrations compared with other fertilizers ( chemical and green fertilizers ) . All green
fertilizers ( Lentil , Vetch , Faba bean and Barely ) significantly increased organic matter ,
nitrogen and potassium concentration compared with the control without using any
fertilizer , the tillage depth ( 0 – 10 ) cm significantly increased soil content of organic
matter and nitrogen compared with deeper tillage ( 25 – 30 ) cm during the two seasons .
A field experiment was carried out during 2003 and 2004 in Edleb
governorate to study the effect of phosphate solubilizing bacteria (Bacillus
megaterium) and cows manure on solubilization of phosphate rock, cotton
productivity, and phosphate uptak
e. The amounts of phosphate rock and
superphosphate were added by the same amount of P2O5.
An amount of nitrogen fertilizer as urea, was added to treatment 1, 2, 3, 4,
5, and 6 , whereas treatment 7, 8, 9, 10, 11, and 12 received amounts of organic
fertilizer having the same amount of N added to treatment 1-6 (MAAR
recommendation).
