High-resolution soil property maps for Africa were created using machine learning and over 100,000 soil samples. These maps support site-specific agronomy for smallholder farmers.

Area Of Science

  • Agricultural Science
  • Soil Science
  • Geospatial Analysis

Background

  • Accurate soil data is crucial for effective agricultural management.
  • Smallholder farmers often lack access to detailed soil property information.
  • Previous soil maps had limited resolution and scope.

Purpose Of The Study

  • To create high-resolution, open-access soil property maps for Africa.
  • To leverage machine learning for improved soil mapping accuracy.
  • To facilitate site-specific agronomic advice for smallholder farmers.

Main Methods

Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:


Inorganic mineral matter, which constitutes about 40 to 45 percent of the soil volume.
Organic matter, also known as humus, which makes up about 5 percent of the soil volume.
Water and air, covering about 50...

Topographic Surveying and Contours 01:29

Topographic surveying is critical for documenting the Earth's surface, focusing on capturing elevations, slopes, and natural and man-made features. It is essential in construction planning, water resource management, and land-use analysis. The primary outcome of such surveys is a topographic map, which uses contour lines to visually represent the shape and slope of the terrain, providing valuable insights into the landscape's characteristics.Contour lines are fundamental to understanding the...

Plotting of Topographic Maps 01:29

Topographic maps represent the Earth's surface features using contour lines, which connect points of equal elevation to create a two-dimensional representation of three-dimensional terrain. Creating a topographic map requires a systematic approach.Begin by plotting a scaled grid and marking intersections corresponding to the survey's elevation data points. Assign elevation values at these intersections to build the base map. Next, determine contour levels using a consistent contour interval,...

Coordinates and map projections are essential tools in accurately representing the Earth's surface for various applications, ranging from navigation to spatial analysis. The latitude and longitude coordinate system is a universally recognized framework for defining locations. Latitude specifies the distance of a point north or south of the equator, measured in degrees from 0° at the equator to 90° at the poles. Longitude indicates a location's position east or west of the prime meridian,...
