في تجربة حقلية أجريت في محافظة طرطوس (قرية كرتو), في الموسم الزراعي (2014-2013), استخدمت معدلات من أسمدة عضوية مختلفة المنشأ. كان عدد المعاملات عشرة معاملات,شاهد (بدون تسميد ),سماد روث أغنام بمعدل(30-20-10)طن/ه ,سماد روث أبقار
(30-20-10)طن/ه , سماد زرق دواجن (30-20-10)طن/ه.
هدفت الدراسة إلى معرفة تأثير إضافة هذه الأسمدة في الخواص البيولوجية للتربة (أعداد بعض المجاميع الفيزيولوجية للأحياء الدقيقة, و تنفس التربة) و بعض الخواص الخصوبية للتربة. بينت النتائج زيادة أعداد البكتريا غير ذاتية التغذية و الأكتينوميسيتات معنوياً في الترب المعاملة بسماد زرق الدواجن (20),(30) طن/ه, و زيادة معنوية لأعداد البكتريا
المستخدمة للآزوت المعدني, و الأحياء الدقيقة المحللة للسيللوز, و الفطريات في الترب المعاملة بسمادي زرق الدواجن ( 30 ) طن/ه, و سماد روث الأبقار ( 30 ) طن/ه .
أما من الناحية الخصوبية فقد أظهرت النتائج أن إضافة الأسمدة العضوية أدت إلى انخفاض معنوي في pH التربة في الترب المعاملة بسماد روث الأبقار ( 30 ) طن/ه , و سماد روث الأغنام ( 20 ) طن/ه, كما سجل ازدياد لمحتوى التربة من المادة العضوية في الترب المعاملة بسمادي زرق الدواجن ( 30 ) طن/ه, و سماد روث الأبقار ( 30 )طن/ه, و زيادة لمحتوى التربة من الفوسفور و البوتاسيوم القابلين للإفادة .
In field's experiment had been done in the Tartus governorate during the growing season (2013-2012) Different rates of organic fertilizers were used, the experimental transactions were (10) treatments, control (without fertilization) sheep wastes(10-20-30)tn/h, cow wastes(10-20-30)tn/h, poultry wastes(10-20-30)tn/h.
This study aimed to know the effect of adding these fertilizers on
biological properties of the soil (the number of physiological groups of microorganisms, and soil respiration).
The Results showed increasing in the number of Hertotrophic
bacteria , Actenomycetes in the soils which were fertilized in
poultry wastes(20),(30)tn/h, and increasing in the number
of(bacteria, using mineral from nitrogen, and decomposed of
celluose micro organisms) in the soils which were fertilized in
poultry wastes(30)tn/h and cow wastes(30)tn/h.
As for fertilization, The Results showed decreasing pH in the soils
which were fertilized cow wastes(30)tn/h, while soil contents of
available P and K and organic mater increased in soil which were
treated fertilized in poultry wastes(20),(30)tn/ h, and cow
wastes(30)tn/h.
