Sustainable pasture production on reclaimed coal mine soils
Coal mining impacts large areas in the grasslands of the Mpumalanga Province of South Africa.To mitigate such impacts, it is imperative to restore the once productive soils to the best possible condition.The re‐vegetation of mined land presents a particular challenge because cover soils are often acidic and nutrient deficient.It is current practice to amend such soils using lime and inorganic fertilizer.Research over the past 8‐10 years into the use of a coal combustion by‐product (CCBs)‐class F fly ash,and an organic material such as sewage sludge,has demonstrated the feasibility of using such materials to amend acidic and infertile substrates (Norton et al., 1998 ; Truter and Rethman,2002 ; Truter,2007).The objective of this research was to determine if alternative amendments could create a more sustainable system, in which botanical composition, basal cover, plant productivity and soil chemical properties were improved.
