There is limited knowledge regarding the impact of nitrification inhibitors (NIs) and straw application on fertilizer N retention in-season release. We conducted a trial to study transformation 15 N-labeled urea in soils during growing season maize. To facilitate multiple destructive samplings throughout season, we utilized larger plot (25 m 2 ) lower abundance N-fertilizer (1.193%) than usual. Soil extractable mineral N, fixed ammonium, organic (ON) recovered 20 ± 21% (mean standard...
Reducing fertilizer-N rate, applying a nitrification inhibitor (NI), and incorporating straw are widely recommended to improve N use efficiency of crops decrease losses. A field 15N tracer study was conducted compare their effectiveness on fates during the maize growing season in Northeast China. The following six treatments were used: (1) no fertilization (control); (2) 200 kg urea-N ha−1 (100%N); (3) (100%N + S); (4) 160 (80%N); (5) NI (Nitrapyrin this study) (80%N NI); (6) ha−1, NI, S)....
As nitrous oxide (N 2 O) is one of the most important greenhouse gases, N O emission pathways and regulation techniques in soils with different vegetation types have become a research focus. Currently, diverse array exists on emissions from types, e.g., forest, grassland, agriculture. Few studies investigated microbial processes lawn soils. Fertilization levels are often similar to or much higher than those agricultural ecosystems, thus fertilized an source atmospheric O. In study, we...
Reducing fertilizer-N rate, applying nitrification inhibitor (NI), and incorporating straw are widely recommended to improve N use efficiency of crops decrease losses. However, how these practices affect crop uptake by regulating the fate during growing season is not well understood. We conducted a field 15N tracer study explore effectiveness reduced application, NI, incorporation on fates for maize cultivation in Northeast China. The following six treatments were used: 1) no fertilization...
Well logs play a very important role in exploration and even exploitation of energy resources, but they usually contain kinds noises which affect the results geological interpretation them. It is common knowledge that wavelet transform does better than Fourier noise removal suppression such non-stationary signals as logging signals. However, there are variable choices parameters basis (mother function), thresholding rule decomposition level etc. denoising with transform. In this paper,...
<title>Abstract</title> <italic><bold>Background and Aims: </bold></italic>The application of nitrification inhibitor (NI) crop straw with nitrogen (N) fertilizer is a common practice to increase soil N conservation use in cropping systems. However, their effects on gaseous emission from soils are less understood, especially for N<sub>2</sub>. <italic><bold>Methods: </bold></italic>We conducted 60-day incubation experiment study the NI or maize N<sub>2</sub>O N<sub>2</sub> emissions two...
