Investigating the Quality and Efficiency of Biosolid Produced in Qatar as a Fertilizer in Tomato Production

This study evaluated biosolid quality over time and the efficiency of using amounts (5 7 kg/m2) municipal class A biosolids in Qatar to fertilize tomato plants (Solanum lycopersicum). Random samples were subjected physical chemical analysis, which revealed excellent particle uniformity stability with minor odor defects. The analysis confirmed product was nutrient-rich while pollutant levels below international standards. nominated rates used pots grown a greenhouse for four months control treatment manure Peat-Moss, before measuring plant biological characteristics. Plants examined via nutrients pollutants both whole stems, fruits, leaves. Results indicated that experimental treatments enhanced growth development as compared treatment. However, analyses also zinc, copper, manganese fruits well excess maximum acceptable levels, defined by health organizations. found application organic fertilizer greatly overall growth, contained toxic trace heavy metals.
