Overview

What is he best known for?

The fields of study he is best known for:

  • Agronomy
  • Botany
  • Irrigation

Leonard Wade mainly investigates Agronomy, Oryza sativa, Soil water, Soil organic matter and Poaceae. His Agronomy research includes elements of Lowland rice and Soil fertility. His research in Oryza sativa focuses on subjects like Botany, which are connected to Superoxide dismutase and Chloroplast.

His work in the fields of Soil water, such as Soil carbon and Humus, intersects with other areas such as Phosphorus. His Poaceae research includes themes of Rainfed agriculture, Phenology, Quantitative trait locus, Japonica and Root system. His Cultivar research integrates issues from Photosynthesis, Rice plant and Upland rice.

His most cited work include:

  • Proteomic analysis of rice leaves during drought stress and recovery (392 citations)
  • Stable soil organic matter: A comparison of C:N:P:S ratios in Australian and other world soils (261 citations)
  • Genetic analysis of drought resistance in rice by molecular markers: association between secondary traits and field performance (254 citations)

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

Agronomy, Soil water, Agroforestry, Root system and Lowland rice are his primary areas of study. His studies deal with areas such as Oryza sativa and Hardpan as well as Agronomy. His Subsoil and Soil organic matter study in the realm of Soil water connects with subjects such as Phosphorus.

His Agroforestry research focuses on Perennial plant and how it relates to Waterlogging, Sustainable agriculture and Mixed farming. The Root system study combines topics in areas such as Drought tolerance, Pasture and Water content. His Poaceae research is multidisciplinary, relying on both Quantitative trait locus, Transpiration, Rainfed agriculture and Seedling.

He most often published in these fields:

  • Agronomy (90.48%)
  • Soil water (22.62%)
  • Agroforestry (21.43%)

What were the highlights of his more recent work (between 2010-2015)?

  • Agronomy (90.48%)
  • Soil water (22.62%)
  • Dry matter (8.33%)

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

The scientist’s investigation covers issues in Agronomy, Soil water, Dry matter, Hardpan and Root system. Many of his studies on Agronomy involve topics that are commonly interrelated, such as Animal science. His Dry matter research is multidisciplinary, incorporating perspectives in Water use, Agroforestry, Water deficit and Perennial plant.

In his work, Soil horizon, Soil classification, Subsoil, Quantitative trait locus and Doubled haploidy is strongly intertwined with Wax, which is a subfield of Hardpan. The Root system study which covers Water content that intersects with Crop, Cropping, Pasture and Drought resistance. Leonard Wade has researched Soil organic matter in several fields, including Soil carbon and Humus.

Between 2010 and 2015, his most popular works were:

  • Stable soil organic matter: A comparison of C:N:P:S ratios in Australian and other world soils (261 citations)
  • Carbon-nutrient stoichiometry to increase soil carbon sequestration (171 citations)
  • Nutrient availability limits carbon sequestration in arable soils (140 citations)

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

  • Agronomy
  • Botany
  • Irrigation

His main research concerns Agronomy, Soil water, Soil organic matter, Phosphorus and Humus. His Agronomy and Germplasm and Grain quality investigations all form part of his Agronomy research activities. Phosphorus is integrated with Straw, Carbon sequestration, Arable land, Terrestrial ecosystem and Environmental chemistry in his study.

His Humus research is multidisciplinary, incorporating elements of Soil type, Soil carbon, Soil fertility, Crop residue and Animal science. His research on Soil carbon concerns the broader Soil science.
