Nitrogen retention capacity of paddy soil improved under long-term garlic-rice rotation
Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2023 Although significant differences in soil nitrogen levels exist under different paddy-upland rotations, the main reason for this is unclear. The nitrogen retention capacity and loss of ammonia volatilisation, leaching, etc.

NITROGEN ISOTOPIC FRACTIONATION IN INTERSTELLAR AMMONIA [PDF]
The Astrophysical Journal, 2010 Using the Green Bank Telescope (GBT), we have obtained accurate measurements of the $^{14}$N/$^{15}$N isotopic ratio in ammonia in two nearby cold, dense molecular clouds, Barnard~1 and NGC 1333. The $^{14}$N/$^{15}$N ratio in Barnard~1, $334 \pm 50$ (3$σ$), is particularly well constrained and falls in between the local interstellar medium/proto-solar

A hybrid intelligent soft computing method for ammonia nitrogen prediction in aquaculture
Information Processing in Agriculture, 2021 Ammonia nitrogen is one of the key parameters in determining the aquaculture water quality condition in pond. The high level of ammonia nitrogen is likely to cause deterioration of water quality and mass death of cultured subjects.

Experimental Study on Ammonia Nitrogen Adsorption Performance of Zeolite Powder
Chemical Engineering Transactions, 2015 The incidents of sudden pollution of ammonia nitrogen are happening quite frequently recently. To study the effective removal of ammonia nitrogen, using zeolite powder as an absorbent, the simulation of ammonia- nitrogen wastewater is studied ...
