Data from a survey of nematodes associated with sugarcane conducted in South Africa in 1978 (Spaull, 1981) were re-examined in combination with associated soil, climatic and topographic data. The objective was to identify associations between the distribution of the nematodes and soil, climatic and topographic factors in sugarcane fields in KwaZulu-Natal. The procedures used in the survey are s...

Soil science is a relatively new discipline which has mainly developed since the 1880s. It uses terms, methods and processes borrowed from other basic disciplines like climatology, geology, chemistry, physics and biology, but with a direct application to soils. At present, it is difficult to speak about one single science but as soil sciences, as they cover several fields including: pedology (o...

During recent strategic planning exercises, the SSSA identified several trends related to the soil science profession: 1) declining academic programs and course offerings at land-grant universities, 2) decreased enrollments, and 3) improved employment opportunities for soil science graduates. To quantify these trends, the SSSA conducted surveys in 2008 of soil science students, academic departm...

During the past two decades, soil survey as many other applied scientific disciplines has been dealing with a rapidly changing society and consequent shifts in public and private information needs for planning and management. Concurrently, soil survey has been faced with the advent of a whole range of new technologies, many of them highly relevant to the planning and execution of soils resource...

Soil metal surveys were conducted in Baltimore, MD (1976-1979), Minnesota (1981-1988) and most recently, New Orleans, LA (1989-present). The unique characteristic of New Orleans is that it has two surveys; Survey I was completed in 1992 and Survey II was completed in 2000. This paper seeks to determine if there is a perceptible change in the amount of metals during less than a decade that separ...
