Standardization of A Sample-Processing Methodology for Stable Isotope Studies in Poultry

Brazilian Journal of Poultry Science, 2019
The objective of this study was to determine if lipid extraction processes alter the isotopic value of δ13C and δ15N of tissues (pectoral muscle, thigh and liver) and eggs and if the use of anticoagulants interferes with blood and plasma δ13C and δ15N ...

N Utilization, Residual and Loss Characteristics of Spring-Topdressing (¹⁵N-urea) Pear Orchards in the Old Course of the Yellow River Area

Agronomy, 2022
In the old course of the Yellow River area, most orchards are over-applied with nitrogen (N) fertilizers. To improve N management in this area, a 15N tracing experiment was conducted to investigate the absorption, distribution and loss of spring ...

The Nitrogen Fixation and Yielding of Pea in Different Soil Tillage Systems

Agronomy, 2022
The field experiment was carried out in 2013 and 2014 as part of a long-term experiment to test the influence of different soil tillage systems (conventional, reduced, direct sowing) on (a) the yield of summer pea (Pisum sativum L.) and (b) the amount of

Traceability of poultry offal meal in broiler feeding using isotopic analysis (δ13C and δ15N) of different tissues

Brazilian Journal of Poultry Science, 2010
Our goal was to trace the inclusion of poultry offal meal (OM) in diets by using carbon (13C/12C) and nitrogen (15N/14N) isotopic ratios of different tissues in order to contribute for the development of an independent technology for the certification of

PENGARUH APLIKASI ASAM HUMAT DAN PUPUK NPK PHONSKA 15-15-15 TERHADAP SERAPAN NITROGEN DAN PERTUMBUHAN TANAMAN PADI SERTA RESIDU NITROGEN DI LAHAN SAWAH

JTSL (Jurnal Tanah dan Sumberdaya Lahan), 2020
The decline in lowland rice production can be caused by nitrogen nutrient loss through volatilization. The application of humic acid and Phonska 15-15-15 fertilizer can be a solution. This study aimed to determine the effect of humic acid and Phonska 15-
