There are many plants extract and many chemical compounds were decreasing volatile ammonia from the soil after adding Nitrogen fertilizer. In this study test many plants extract to know the ability this extracts on decreasing ammonia volatilization with many concentration (1.5 , 3 , 4.5) ml/100 g soil and Hydroquinone used to same aim .
The result explained all treatment of plant extracts and Hydroquinone compound with 1.5 ml/100 g soil and 2.5 mg/100 g soil respectively. Caused decreasing ammonia volatilization p<0.05 except plant extract of Vigna radiata , caused increasing a significantly different p<0.05 to ammonia volatilization compared with control treatment ( soil and fertilizer only) in the second experiment used concentration 3 ml/100 g soil and 5 mg/100g soil of Hydroquinone. The result explained that the rate of ammonia volatilization were ( 10.8 , 4.1 , 5 , 13.5 , 4.2 , 4 , 2.8 , 2.7 ) mg NH3/100 g soil to Hydroquinone , Phaseolus vulgaris, Pennisetum americanum, Cinnamomum zeilanicum Nees, Eucalyptus camaldulensrs Dehnl, Vigna radiata, Matricaria chmomilla and Tribulus terrestis L. respectively.
All this plant extracts caused a significantly decreasing ammonia volatilization p<0.05 except Hydroquinone treatment and Cinnamomum zeilanicum Nees caused increasing ammonia volatilization compared with control treatment in this concentration 3 ml/100g soil in other experiment used plant extract to the same plants with 4.5 ml/100 g soil and 7.5 mg/100 g soil of Hydroquinone in the experiment to know effecting increasing concentration of this plant and Hydroquinone an ammonia volatilization the result explained that all plant extracts recorded a significantly different decreasing ammonia volatilization except Vigna vadiata the rate of volatile ammonia were ( 5.6 , 5.5 , 4.8 , 5 , 3.6 , 3.7 , 2.7 ) mg NH3/100 g soil to Hydroquinone , Phaseolus vulgaris, Pennisetum americanum, Cinnamomum zeilanicum Nees, Eucalyptus camaldulensrs Dehnl, Matricaria chmomilla and Tribulus terrestis L. respectively, compared with control treatment .
The interaction between treatment and concentration explained that the highest a volatile ammonia got with Vigna radiata in the concentration 1.5 ml/100 g soil and was 17.8 mg NH3/100 g soil and the lowest volatile ammonia was 2.6 mg NH3/100 g soil to Hydroquinone .
There are not any a significant difference at volatile ammonia among the concentration ( 1.5 , 3 , 4.5 ) ml/100 g soil and were 5.77 , 5.81 and 5.21 mg NH3/100 g soil.
