Overview

What is he best known for?

The fields of study he is best known for:

  • Agronomy
  • Fertilizer
  • Soil water

Reynald L. Lemke spends much of his time researching Soil water, Agronomy, Crop rotation, Tillage and Crop. His Soil management study in the realm of Soil water connects with subjects such as Ecodistrict. His research integrates issues of Carbon footprint and Crop residue in his study of Agronomy.

His biological study spans a wide range of topics, including Soil organic matter, Soil carbon, Soil classification and Chernozem. Dry matter, Growing season and No-till farming is closely connected to Manure in his research, which is encompassed under the umbrella topic of Tillage. His Crop study incorporates themes from Legume, Water-use efficiency, Soil retrogression and degradation, Seeding and Erosion.

His most cited work include:

  • Estimation of N2O emissions from agricultural soils in Canada. I. Development of a country-specific methodology (200 citations)
  • Improving farming practices reduces the carbon footprint of spring wheat production (136 citations)
  • Crop residue removal and fertilizer N: Effects on soil organic carbon in a long-term crop rotation experiment on a Udic Boroll (135 citations)

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

His primary areas of investigation include Agronomy, Soil water, Crop rotation, Fertilizer and Tillage. His Agronomy research includes elements of Cropping and Chernozem. His Soil water study combines topics in areas such as Moisture, Seeding and Water content.

His research on Crop rotation also deals with topics like

  • Monoculture and related Elymus and Elytrigia,
  • Soil carbon, which have a strong connection to Crop residue. The various areas that Reynald L. Lemke examines in his Fertilizer study include Leaching, Straw and Manure. His Tillage study integrates concerns from other disciplines, such as Coated urea and Soil horizon.

He most often published in these fields:

  • Agronomy (81.13%)
  • Soil water (30.19%)
  • Crop rotation (24.53%)

What were the highlights of his more recent work (between 2015-2021)?

  • Agronomy (81.13%)
  • Cropping (16.04%)
  • Soil water (30.19%)

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

The scientist’s investigation covers issues in Agronomy, Cropping, Soil water, Growing season and Fertilizer. His Soil carbon research extends to the thematically linked field of Agronomy. His Cropping research is multidisciplinary, incorporating elements of Agroforestry and Linear regression.

His research in the fields of Soil biodiversity overlaps with other disciplines such as Microbial population biology. As part of the same scientific family, Reynald L. Lemke usually focuses on Growing season, concentrating on Growing degree-day and intersecting with Field experiment and Annual percentage yield. His study in Fertilizer is interdisciplinary in nature, drawing from both Silage and Loam.

Between 2015 and 2021, his most popular works were:

  • Soil nitrous oxide emissions from agricultural soils in Canada: Exploring relationships with soil, crop and climatic variables (37 citations)
  • Microbial crop residue decomposition dynamics in organic and conventionally managed soils (35 citations)
  • A multi model evaluation of long-term effects of crop management and cropping systems on nitrogen dynamics in the Canadian semi-arid prairie (15 citations)

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

  • Agronomy
  • Fertilizer
  • Botany

His primary areas of study are Soil water, Agronomy, Cropping, Growing season and Crop. His Soil water research is multidisciplinary, incorporating perspectives in Greenhouse, Environmental engineering, Irrigation, Water content and Moisture. His Agronomy study combines topics from a wide range of disciplines, such as Leaching, Linear regression, Crop residue, Decomposer and Nutrient cycle.

The Cropping study combines topics in areas such as DayCent, Loam and Cropping system. His Growing season research incorporates elements of Precipitation, Soil texture, Soil pH, Crop yield and Yield. His work deals with themes such as Denitrification, Diurnal cycle and Spring, which intersect with Crop.
