Adopting of drink water conditions needs sterilization from the resource. There are many used matter to sterilize, but the most use is by Chloride, so it is necessary to obtain solutions because of continuous damages due to sterilization operation.
The water sterilization by chloride may create secondary compounds in water, which are very dangerous. Those compounds are as Trihalomethanes (THMs) which cause crabs. Therefore, we researched the sterilization by chloride in comparison with other ways. In addition, we get rid off hydro carbonates from sterilized drink water samples, which were obtained from different resources, drink water, natural water and dames using the activated carbon to get rid off venole and humic acids not to interact with chloride and cause people cansers.
The experiment was performed at Agricultural Research Center in Jousiyet
Al-Kharab in Al-Qsair district, Homs governorate during the 2010-2011 season
to investigate the effect of planting depth and organic acids on saffron growth
and productivity.
Four treatments including amino acids, amino Humic,
mixture of them in addition to the control were applied. Each treatment was
comprised of three planting depths (10, 15 and 20 cm). Results showed that by
increasing planting depth up to 20 cm a significant reduction had resulted in
the percentage of rooted plants and number of shoots while there were no
significant differences between the two depths 10 vs. 15 cm. The number of
leaves and their length were not affected significantly with the increasing of
planting depths. The number of flower, wet and dry weights of the stigmas
were increased significantly with the increase of planting depth from 10 to
15 cm. The application of the humic acids had significant superiority overall
the other applications in rooted plant percentage, number of shoots, number of
flowers and the dry and wet weights of the stigmas, while the application of the
mixture came in the second rank in number of flowers and the dry and wet
weights of the stigmas. However, no significant differences were occurred
between the control and application of amino acids. The highest percentage of
rooted plants was observed in applying humic acids in all depths and the
percentage of rooted plants reached 100%. The highest number of flowers,
highest stigmas wet and dry weights were observed with the interaction
between applying humic acids at 15 cm depth. The highest number of shoots
and number of leaves appeared with the interaction between 20 cm depth and
humic acids treatment, the longist leaves were appeared with the interaction
between amino acids and 15 cm depth.
Some chemical, spectral and thermal characteristics of some humic acids
(HA) extracted from: Farm manure (Fm), biogas(Bio), compost (Com), forest
litters of pine (Pl) and of descendant forest (Dl), and their complexes with Camontmorillonite
were s
tudied by TGA and DTA analysis.
