The Chisumbanje Estate
There are currently 6,000 hectares of sugarcane planted within the Chisumbanje Estate.
The area is flat with very gentle basalt plain slopes offering a natural network of drainage lines, forming the largest single tract of relatively deep basalt-derived soils in Zimbabwe, extending over 40,000 hectares. The majority of these soils consist of dark grey and black self-churning clays, characterised by loose granular surface horizons of varying thickness.
Although the soils of this area are of a very high quality, they have special management requirements and infiltration can be a challenge. We therefore use best practice management techniques to control it, for example leaving a trash blanket on the ground after green cane harvesting.
Fertiliser programs are calculated upon the results of high density GPS soil sampling surveys to ensure that nutrients are not wasted.
The Middle Sabi Estate is located 80km from Chisumbanje and there are currently 3,500 hectares of sugarcane planted there.
The soils on this estate consist of alluvial silt and sand deposits with course gravel or sand sub soils making for good drainage and their ideal suitability to pivot irrigation. Soil chemistry shows average to good natural levels of all three iron nutrients – phosphate, potash and nitrogen.
