Overview

What is he best known for?

The fields of study he is best known for:

  • Agriculture
  • Ecology
  • Ecosystem

Soil fertility, Agroforestry, Nutrient, Erosion and Land use are his primary areas of study. His Soil fertility research is multidisciplinary, incorporating elements of Soil classification and Fertilizer. His Agroforestry research includes elements of Soil organic matter, Soil management, Soil nutrients and Leaching.

His biological study spans a wide range of topics, including Agroecosystem and Soil water. He usually deals with Erosion and limits it to topics linked to Sustainability and Temporal scales. Eric Smaling interconnects Nutrient management and Agronomy in the investigation of issues within Land use.

His most cited work include:

  • Assessment of soil nutrient depletion in sub-Saharan Africa: 1983-2000. (394 citations)
  • Integrated soil fertility management: Operational definition and consequences for implementation and dissemination (374 citations)
  • A system for quantitative evaluation of the fertility of tropical soils (QUEFTS). (370 citations)

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

His primary areas of study are Soil fertility, Agroforestry, Agriculture, Agronomy and Nutrient. Eric Smaling combines subjects such as Fertilizer, Leaching, Soil nutrients, Manure and Soil management with his study of Soil fertility. The Soil management study combines topics in areas such as Soil organic matter and Soil retrogression and degradation.

His Agroforestry research incorporates elements of No-till farming, Erosion, Land use and Sustainability. His work on Nutrient management as part of general Agriculture research is frequently linked to Business, thereby connecting diverse disciplines of science. His work on Crop, Pennisetum and Crop yield as part of general Agronomy research is often related to Striga hermonthica, thus linking different fields of science.

He most often published in these fields:

  • Soil fertility (57.32%)
  • Agroforestry (41.46%)
  • Agriculture (48.78%)

What were the highlights of his more recent work (between 2010-2019)?

  • Agroforestry (41.46%)
  • Agriculture (48.78%)
  • Remote sensing (13.41%)

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

Eric Smaling mainly investigates Agroforestry, Agriculture, Remote sensing, Normalized Difference Vegetation Index and Land cover. His Agroforestry research incorporates themes from Soil carbon, Soil fertility, Soil nutrients, Manure and Land degradation. His study in Soil fertility is interdisciplinary in nature, drawing from both Land development and Land use, land-use change and forestry.

Eric Smaling performs integrative study on Agriculture and Wildlife conservation in his works. His Land cover research is classified as research in Land use. Eric Smaling works mostly in the field of Land use, limiting it down to concerns involving Cartography and, occasionally, Economy.

Between 2010 and 2019, his most popular works were:

  • Rice yields and yield gaps in Southeast Asia: Past trends and future outlook (115 citations)
  • Rice yields and yield gaps in Southeast Asia : past trends and future outlook + corrigendum (90 citations)
  • Mapping the irrigated rice cropping patterns of the Mekong delta, Vietnam, through hyper-temporal SPOT NDVI image analysis (90 citations)

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

  • Agriculture
  • Ecology
  • Ecosystem

Eric Smaling focuses on Southeast asia, Yield, Agricultural economics, Soil carbon and Soil science. Southeast asia combines with fields such as Past Trends, Yield gap, Food processing, Trend analysis and Cultivar in his work. The concepts of his Soil carbon study are interwoven with issues in Standard deviation, Digital soil mapping, Soil test, Kriging and Geostatistics.

In most of his Digital soil mapping studies, his work intersects topics such as Spatial variability. The various areas that he examines in his Spatial variability study include Cropping, Agriculture, Flooding and Vegetation. His Soil science study combines topics in areas such as Mean squared error, Standard error and Sample size determination.
