  • Ecology
  • Agriculture
  • Agronomy

His main research concerns Agronomy, Soil water, Soil organic matter, Organic matter and Soil carbon. His study in Agronomy is interdisciplinary in nature, drawing from both Topsoil, Soil biodiversity, No-till farming, Nutrient and Vertisol. His research in Soil water intersects with topics in Environmental chemistry, Total organic carbon, Fertilizer, Greenhouse gas and Poaceae.

Ram C. Dalal combines subjects such as Soil chemistry, Soil fertility and Soil quality with his study of Soil organic matter. His work carried out in the field of Organic matter brings together such families of science as Urea, Soil color and Mineralization. His Soil carbon research is multidisciplinary, relying on both Carbon sequestration and Soil salinity.

His most cited work include:

  • Nitrous oxide emission from Australian agricultural lands and mitigation options: a review (491 citations)
  • APSIM's water and nitrogen modules and simulation of the dynamics of water and nitrogen in fallow systems (444 citations)
  • Simultaneous Determination of Moisture, Organic Carbon, and Total Nitrogen by Near Infrared Reflectance Spectrophotometry (424 citations)

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

His scientific interests lie mostly in Agronomy, Soil water, Soil organic matter, Soil carbon and Vertisol. His Agronomy research incorporates themes from No-till farming and Soil fertility. His study explores the link between Soil water and topics such as Total organic carbon that cross with problems in Soil respiration.

His Soil organic matter research is multidisciplinary, incorporating perspectives in Organic matter, Humus and Soil horizon. His Soil carbon research incorporates elements of Agroforestry, Soil type, Pasture, Carbon sequestration and Greenhouse gas. Ram C. Dalal studied Vertisol and Crop residue that intersect with Incubation and Mineralization.

He most often published in these fields:

  • Agronomy (61.87%)
  • Soil water (40.80%)
  • Soil organic matter (36.79%)

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

  • Agronomy (61.87%)
  • Soil carbon (35.79%)
  • Soil water (40.80%)

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

Ram C. Dalal mainly investigates Agronomy, Soil carbon, Soil water, Vertisol and Tillage. His Agronomy study integrates concerns from other disciplines, such as Soil organic matter, Soil type, Crop residue and Soil fertility. His Soil carbon research includes elements of Environmental protection, Carbon sequestration, Global warming, Greenhouse gas and No-till farming.

The study incorporates disciplines such as Cropping and Fertilizer in addition to Soil water. Ram C. Dalal has included themes like Soil structure, Alfisol, Minimum tillage and Bulk soil in his Vertisol study. The concepts of his Tillage study are interwoven with issues in Crop yield, Crop rotation, Soil health and Water content.

Between 2017 and 2021, his most popular works were:

  • Nitrogen-rich microbial products provide new organo-mineral associations for the stabilization of soil organic matter. (41 citations)
  • Agricultural management practices impacted carbon and nutrient concentrations in soil aggregates, with minimal influence on aggregate stability and total carbon and nutrient stocks in contrasting soils (39 citations)
  • Impact of agricultural management practices on the nutrient supply potential of soil organic matter under long-term farming systems (32 citations)

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

  • Ecology
  • Agriculture
  • Ecosystem

Vertisol, Agronomy, Soil water, Soil carbon and Tillage are his primary areas of study. In his study, Nutrient and Crop yield is strongly linked to Crop residue, which falls under the umbrella field of Agronomy. His work on Soil water deals in particular with Soil organic matter and Soil horizon.

He has included themes like Organic matter, Cenchrus ciliaris, Cover crop, Carbon-to-nitrogen ratio and Subsoil in his Soil organic matter study. His Soil carbon study integrates concerns from other disciplines, such as Reforestation, Tropics, Soil structure, Biomass and Conservation agriculture. His Tillage research incorporates themes from Soil type and Soil health.
