eLEAF is providing PiMapping® data on crop growth and water use to Illovo Sugar, British Sugar’s subsidiary in Africa. For Nchalo, a 17,000ha estate in Malawi, satellite based data is delivered on a biweekly basis at a resolution of 10m. The data is delivered via the Remote Cane Management (RCM) website by SQR, which is already used by Illovo for sugarcane management.
Illovo is using PiMapping® data to:
- Improve agricultural production and agronomy support – PiMapping® data is used to capture spatial trends and patterns of agronomic interventions to measure the success and yield impacts during the growing season and possibly during the next ratoon
- Yield estimation – during the growing season biomass production and LAI are used to estimate the amount of biomass that is accumulated in the stalks to calculate yield
- Support irrigation management – the effectiveness of emergence irrigation and irrigation practices have been assessed in the short, medium and long term depending on crop development for the range of irrigation systems
The PiMapping® products delivered are actual and potential biomass production all in kg/ha biweekly: actual evapotranspiration (mm biweekly), biomass water productivity (kg/m3 biweekly), nitrogen top leaf (kg/ha) and LAI (m2/m2).
Besides providing PiMapping® via RCM, eLEAF provides support sessions on data interpretation, crop development assessment and implementation of decisions concerning agronomic interventions. This is done in Malawi as well as via distance learning.
