The Farm Klein Boesman, south of Dordabis in the Khomas Region of Central Namibia, is situated on the ecotone between the Central Highlands/Central Plateau and the southern Kalahari. Whereas a considerable amount of information is available for the Kalahari Duneveld in South Africa, little is known of the same ecosystem in Namibia, specifically the...

Massive investments in climate change mitigation and adaptation are projected during coming decades. Many of these investments will seek to modify how land is managed. The return on both types of investments can be increased through an understanding of land potential: the potential of the land to support primary production and ecosystem services, a...

ENGLISH ABSTRACT: A number of chemical and physical features of Namibian soils in a 22 790 km2, two degree-square block between 17 – 19 oE and 22 – 23 oS in eastern central Namibia, had been investigated, and the fertility status established. In 80 % of samples the nitrate, nitrite, and sulfate concentrations of the saturated paste extract are 0 –...

The Namibian authorities endeavour to implement a rangeland resources management policy at national level. The first line of action is the allocation of livestock marketing priorities to the most drought‐affected areas. Another potential application is the estimation of land value in terms of grazing capacity, as a base for land purchase and redist...
Article

Four methods were compared to measure the small amounts of organic matter present in many Namibian soils and to detect organic amendments added to improve fertility. Two Walkley-Black wet oxidation methods involving titration (WBT-C) and colourimetry (WBC-C) and two loss on ignition methods involving combustion at 360°C after drying at 105°C (LOI-1...

Errors due to mistakes in sample handling, labeling, data transcription, and computation may be undetected by normal quality control/quality assurance (QA/QC) procedures. Manual detection of random errors relies on a thorough knowledge of soil properties, which may be lacking in technical staff. This paper describes the development of a checking sy...

A preliminary soil map of Namibia had been produced in 2000. The current project draws on work done since then to update the map and database.
