Overview

What is he best known for?

The fields of study he is best known for:

  • Agriculture
  • Ecology
  • Agronomy

His scientific interests lie mostly in Soil carbon, Agronomy, Soil water, Soil organic matter and Agroforestry. His Soil carbon research incorporates elements of Carbon sequestration, Soil quality, Hydrology and Soil retrogression and degradation. Rattan Lal has included themes like No-till farming, Loam, Crop residue and Alfisol in his Agronomy study.

His research integrates issues of Total organic carbon and Crop yield in his study of Soil water. His biological study spans a wide range of topics, including Soil biology, Organic matter, Humus and Soil fertility. His study on Agroforestry also encompasses disciplines like

  • Soil management which intersects with area such as Soil biodiversity, Soil functions, Soil structure and Manure,
  • Agriculture which is related to area like Water resources.

His most cited work include:

  • Soil carbon sequestration impacts on global climate change and food security. (4049 citations)
  • Soil structure and management: a review (2186 citations)
  • Soil carbon sequestration to mitigate climate change (2067 citations)

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

Rattan Lal mainly focuses on Agronomy, Soil carbon, Soil water, Agroforestry and Tillage. As a part of the same scientific study, Rattan Lal usually deals with the Agronomy, concentrating on No-till farming and frequently concerns with Cover crop. His work deals with themes such as Soil quality, Soil organic matter, Soil retrogression and degradation, Carbon sequestration and Soil management, which intersect with Soil carbon.

His Soil retrogression and degradation study which covers Environmental protection that intersects with Climate change. His Soil water research entails a greater understanding of Soil science. His research in Agroforestry focuses on subjects like Soil biodiversity, which are connected to Soil health.

He most often published in these fields:

  • Agronomy (34.33%)
  • Soil carbon (32.01%)
  • Soil water (25.67%)

What were the highlights of his more recent work (between 2016-2021)?

  • Soil carbon (32.01%)
  • Agronomy (34.33%)
  • Agriculture (12.97%)

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

Rattan Lal spends much of his time researching Soil carbon, Agronomy, Agriculture, Soil water and Agroforestry. While the research belongs to areas of Soil carbon, Rattan Lal spends his time largely on the problem of Carbon sequestration, intersecting his research to questions surrounding Ecosystem. His Agronomy research integrates issues from No-till farming and Soil quality.

He focuses mostly in the field of Agriculture, narrowing it down to matters related to Greenhouse gas and, in some cases, Climate change. His Soil water study is concerned with the larger field of Soil science. His study looks at the relationship between Agroforestry and topics such as Soil management, which overlap with Soil biodiversity.

Between 2016 and 2021, his most popular works were:

  • Management of Carbon Sequestration in Soil (380 citations)
  • Soil Quality and Soil Erosion (140 citations)
  • Digging deeper: A holistic perspective of factors affecting soil organic carbon sequestration in agroecosystems. (129 citations)
