Ammonia Loss Mitigation from Urea Amended Sandy and Calcareous Soils Using Zeolite

2018-11-05 00:03:54 Keywords nitrogen, Ammonia volatilizati,
Ammonia Loss Mitigation from Urea Amended Sandy and Calcareous Soils Using Zeolite
The objective of this study was to examine the influence of various zeolite levels on NH3 volatilization from urea fertilizer applied to sandy and calcareous soils. A laboratory incubation experiment in a closed dynamic air flow system was conducted in a completely randomized design with three replications. Four zeolite (clinoptilolite) levels of 0, 12.5, 25 and 50 g kg-1 soil ... Read more

Ammonia Volatilization Reduction Induced by Bentonite Application to Sandy and Calcareous Soils

2018-11-05 00:07:58 Keywords nitrogen, Ammonia volatilizati,
Ammonia Volatilization Reduction Induced by Bentonite Application to Sandy and Calcareous Soils
A laboratory incubation experiment was carried out to study the effect of bentonite application on ammonia volatilization from applied urea fertilizer to sandy and calcareous soils using a closed dynamic air flow system. Four bentonite levels of 0, 1.25, 2.5 and 5% and two urea levels of 250 and 500 kg urea fed-1 wt/wt. All treatments were arranged in a ... Read more
