Abstract
Soil analysis was carried out on samples collected
from a farm located on the out scares of Thokoza Township in
Johannesburg, South Africa. The Farm operational site
currently used for farming was once a waste dumping site. The
moisture content of different samples was determined with an
initial weight of 100g; each sample was placed in an oven and
heated at 107 °C for 2 hours. The X-Ray fluorescence (XRF)
analysis was used in the determination of samples composition.
Magnesium (Mg), Calcium (Ca), Potassium (K) and
Phosphorus (P) were mainly discussed in this study. Horse dung
and crushed bones were reported more suitable as fertilizers
due to large amount of K and P considered as potential plant
growth catalysts. Wood saw dust revealed particularities in its
effect on sand especially in agriculture. The purpose of this
study was to analyse, compare and predict the impact of horse
dung, crushed bones, and wood sawdust in the land remediation
and fertility improvement.
