FORTRESS Veld Improvement Scheme

The grazing areas of FORTRESS have been subdivided into 84 camps, of which the largest is 30 ha. Some former maize fields, have been planted to Smuts Finger, Borseltjie Grass, Clover, Iwag Grass, as well as the indigenous Red Grass (Rooigras) increasing the farm’s carrying capacity by up to four times. FORTRESS has developed simple equipment to convert and improve their old lands (previously ploughed) to quality grazing.

This photo illustrates the Smuts Finger Grass, late in summer (Note the clearly visible rows of Smuts Finger Grass)   This photo shows their Rooigras (Themeda Triandra) successfully planted alongside Smuts Finger Grass (Digitaria Eriantha)

Their veld improvement programme succeeded in March 2003 when old lands were freed of weeds, a seed bed prepared and Rooigras (ThemedaTriandra) been hand sown. Rooigras being the usually dominant preferred indigenous species in the Frankfort area.


In 2004 FORTRESS started to produce compost from their feedlot manure and crop remains, straw or any roughage.

The compost is placed in rows where natural bacteria and fungus break organic matter down, in an aerobic atmosphere to humus. Temperature and moisture are regularly monitored very precisely to create the optimum environment for bacteria and fungus. The process is more or less completed in 80 days. Temperatures of 70 ˚C are reached for 14 days causing weed seeds to become sterile. Moisture content is kept between 30 and 45 %. Compost turning is done by a tractor driven compost turning machine in triangular rows of 1.5 wide and a height of 1.2 m.

More than 3.000 tons of compost are produced annually. Between 2 and 6 tons are spread per hectare on lands and worked in. A saving in artificial fertilizer cost of up to 60 % is gained with this process.
