  • Agriculture
  • Ecology
  • Carbon dioxide

His primary areas of study are Agronomy, Nitrous oxide, Pasture, Soil water and Grazing. His studies in Agronomy integrate themes in fields like Loam, Nitrate and Greenhouse gas. His Nitrous oxide research integrates issues from Carbon dioxide, Manure and Environmental engineering, Effluent.

His Pasture study integrates concerns from other disciplines, such as Dairy farming and Denitrification. His work in Grazing tackles topics such as Topsoil which are related to areas like Drainage, Ruminant and Nitrogen cycle. The study incorporates disciplines such as Field experiment, Soil carbon and Growing season in addition to Fertilizer.

His most cited work include:

  • Denitrification and N2O:N2 production in temperate grasslands: processes, measurements, modelling and mitigating negative impacts. (273 citations)
  • A review of emissions of methane, ammonia, and nitrous oxide from animal excreta deposition and farm effluent application in grazed pastures (179 citations)
  • Gaseous Emissions of Nitrogen from Grazed Pastures: Processes, Measurements and Modelling, Environmental Implications, and Mitigation (164 citations)

What are the main themes of his work throughout his whole career to date?

Agronomy, Nitrous oxide, Soil water, Fertilizer and Manure are his primary areas of study. Jiafa Luo has included themes like Loam, Nitrification and Effluent in his Agronomy study. His Nitrous oxide research is multidisciplinary, incorporating elements of Environmental chemistry, Deposition, Grazed pasture, Greenhouse gas and Animal science.

His research in Soil water focuses on subjects like Denitrification, which are connected to Nitrate and Soil horizon. His work is dedicated to discovering how Fertilizer, Soil carbon are connected with Lignin and Mineralization and other disciplines. As a part of the same scientific study, he usually deals with the Manure, concentrating on Straw and frequently concerns with Ultisol and Dissolved organic carbon.

He most often published in these fields:

  • Agronomy (58.58%)
  • Nitrous oxide (33.14%)
  • Soil water (26.04%)

What were the highlights of his more recent work (between 2018-2021)?

  • Agronomy (58.58%)
  • Fertilizer (24.85%)
  • Nitrous oxide (33.14%)

In recent papers he was focusing on the following fields of study:

Jiafa Luo mostly deals with Agronomy, Fertilizer, Nitrous oxide, Manure and Soil water. The study of Agronomy is intertwined with the study of Soil carbon in a number of ways. His Fertilizer research incorporates themes from Field experiment, Crop yield, Mollisol and Irrigation.

His work deals with themes such as Nitrification, Pasture, Greenhouse gas, Environmental chemistry and Animal science, which intersect with Nitrous oxide. His Manure research is multidisciplinary, incorporating perspectives in Straw, Ultisol and Organic fertilizer. His biological study spans a wide range of topics, including Biogeochemical cycle, Groundwater, Karst, Ecosystem and Denitrification.

Between 2018 and 2021, his most popular works were:

  • Long-term application of manure over plant residues mitigates acidification, builds soil organic carbon and shifts prokaryotic diversity in acidic Ultisols (29 citations)
  • Nitrogen and phosphorus enrichment accelerates soil organic carbon loss in alpine grassland on the Qinghai-Tibetan Plateau (23 citations)
  • Manure over crop residues increases soil organic matter but decreases microbial necromass relative contribution in upland Ultisols: Results of a 27-year field experiment (20 citations)

In his most recent research, the most cited papers focused on:

  • Agriculture
  • Ecology
  • Carbon dioxide

Jiafa Luo mainly investigates Agronomy, Fertilizer, Nitrous oxide, Manure and Soil water. His Agronomy research includes themes of Soil carbon and Loam. In his research, Climate change, Subtropics and Soil classification is intimately related to Soil pH, which falls under the overarching field of Fertilizer.

The various areas that Jiafa Luo examines in his Nitrous oxide study include Pasture based, Pasture, Greenhouse gas and Animal science. His work in Manure addresses subjects such as Straw, which are connected to disciplines such as Crop residue. The various areas that he examines in his Soil water study include Nutrient and Ecosystem.
