  • Fertilizer (21.14%)

What were the highlights of his more recent work (between 2017-2021)?

  • Manure (26.86%)
  • Agriculture (20.00%)
  • Fertilizer (21.14%)

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

Manure, Agriculture, Fertilizer, Nutrient and Greenhouse gas are his primary areas of study. The Manure study combines topics in areas such as Environmental chemistry, Crop residue, Environmental engineering and Compost. His biological study spans a wide range of topics, including Water quality and Natural resource economics.

Fertilizer is a subfield of Agronomy that Gerard L. Velthof studies. His study in the field of Manure management is also linked to topics like Context. His Nitrate research incorporates themes from Soil water, Leaching and Irrigation.

Between 2017 and 2021, his most popular works were:

  • The role of nitrifier denitrification in the production of nitrous oxide revisited (105 citations)
  • China’s livestock transition: Driving forces, impacts, and consequences (92 citations)
  • Benefits and trade‐offs of replacing synthetic fertilizers by animal manures in crop production in China: A meta‐analysis (40 citations)

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

  • Agriculture
  • Ecology
  • Fertilizer

His primary areas of investigation include Greenhouse gas, China, Soil water, Agronomy and Fertilizer. Many of his research projects under Greenhouse gas are closely connected to Greenhouse effect with Greenhouse effect, tying the diverse disciplines of science together. His study focuses on the intersection of China and fields such as Land use with connections in the field of Agricultural science.

His research integrates issues of Surface irrigation, Crop yield and Crop in his study of Soil water. He combines subjects such as Soil horizon, Nitrate, Leaching and Groundwater with his study of Agronomy. As part of the same scientific family, Gerard L. Velthof usually focuses on Soil pH, concentrating on Manure and intersecting with Environmental impact assessment, Anaerobic digestion and Outreach.
