The experiment was set up in a wet lab for 28 d. The environmental parameters of solution and plant weight were monitored every 7 days. The results showed that water lettuce could absorb both ammonium and nitrate, but ammonium uptake was preferential. With approx...
Water infiltration, ammonium, nitrate and phosphate leaching as a function of plant diversity, plant density and total plant biomass in mesocosms containing different earthworm species with and without AMF inoculation. 来自 figshare.com 喜欢 0 阅读量: 13 作者:...
This hypothesis was tested with an in situ nitrogen addition experiment, performed on temperate coastal pine forest soil. Ammonium nitrate in solution with water was applied twice to 9 plots at each of two different water table heights. The applied N levels replicated both increased atmospheric ...
The two compounds that go into this experiment are ammonium nitrate and potassium chloride. Where can you get your hands on these materials? Instant cold packs use ammonium nitrate and water to start an endothermic reaction. The potassium chloride can be found in the grocery store as a table s...

used in the experiment can only be selected from the following substances: Na2CO3, Na2O2, NaCl, Na2O, CaCl2, (NH4) 2CO3, alkali lime and other solid and distilled water. The following fill in the blanks: The main instrument used in the essay A is the desiccant which is chosen ...
water under most conditions and the surface ofnucleic acidsis well hydrated in solution. However, the potential problem of water-relayed ammonium ion-DNA NOEs is easily circumvented by simply irradiating the H2O resonance during the mixing time of theNOESY experiment,10a variation called theMINSY ...
Other additives may be added to this mixture in order to modify the properties of the ANFO explosive, such as guar gums and polyisobutylene, to improve water resistance. The ammonium nitrate particles may also be mixed with emulsion explosives to form AN-emulsion blends, such as for example, ...
On the contrary, anammox rates calculated from 15NO3- experiment were significantly overestimated by 42% without considering nitrate release. In our study this overestimation could only be compensated 14% by taking DNRA into consideration. In a parallel experiment amended with 15NH4+14NO3-, anammox ...
The combination of 15N tracing experiment and numerical modeling method was performed to quantify the specific gross N transformation rates (e.g., DNRA), to analyze the correlation between DNRA and the other N transformations, and to estimate the functional role of DNRA comparing to other N ...
