Ingenio Magdalena (Magdalena) S.A.
Ingenio Magdalena (Magdalena) S.A. farms around 52,000 hectares of sugar cane in Guatemala. In view of the ecological challenges, the company is implementing targeted measures to promote soil biology with the aim of increasing yields while simultaneously contributing to climate change mitigation.
In agriculture, soil fertility is a key factor – not only for stable yields, but also for climate protection and ecosystem resilience. Well-structured soils store large amounts of organic matter, bind carbon and secure long-term productivity. However, monocultures and the intensive use of chemical fertilisers are increasingly endangering these natural functions.

DEG Impulse supported the development of measures to improve soil health as part of its Business Support Services programme.
A central element was the switch to green harvesting. While traditional sugar cane cultivation involves burning the fields before harvesting and then harvesting the remaining sugar canes by hand or machine, Magdalena has now switched to purely mechanical harvesting of 80 percent of its land – without prior burning – reducing significant CO₂ emissions. "After the mechanical harvest, the cut leaves are left on the fields. This allows the soil to store more moisture," explains Francisco Javier Ortega Orozco, Head of Transformation at Magdalena. The result: Water savings of up to 20 percent. This method also inhibits weed growth, which reduces the use of herbicides.
Fazit
The successes of the project are manifold. Magdalena was able to build technical capacity to produce high-quality microbiological compost, significantly reducing the use of mineral fertilisers. The targeted addition of bacteria, fungi and other microorganisms improves the nutrient supply of the soil and promotes its fertility. At the same time, an innovative harvesting technique ensures that CO2 emissions are reduced. “It was particularly exciting for us how holistically the issue of soil was considered,” summarises Anne Schneeweis. "It wasn't about isolated measures. Rather, the different approaches intertwine. This is the only way to identify the crucial adjustments to effectively improve soil quality."
Magdalena actively shares its knowledge at conferences, in associations and in exchange with other sugar cane producers. The aim is to inspire other farmers to adopt similar sustainable practices – and thus jointly promote environmental protection in the industry.
