By skipping the chemicals and going natural, Konpòs Lakay does 4x the work:

  • Compost helps soil to retain moisture in dry periods as well as drain properly during rainy periods.
  • Along with nutrients such as N, P, K, compost adds organic matter back into the soil, thus rebuilding topsoil.
  • Planting trees with compost can help them to build sturdy roots that prevent soil erosion.
  • Research from the Marin Carbon Project shows that compost application increases soil's ability to store carbon, which helps to mitigate the harmful effects of climate change.

SOIL's research has shown that the use of Konpòs Lakay significantly increases yields in the following crops: sorghum, corn, cabbage, carrots, beets, peppers, soy, moringa, and more! With researchers from Stanford University, the University of Hawaii, Université Chrétienne du Nord d'Haïti, Université Polyvalente d'Haïti, Université Episcopale D'Haiti, Université Fondwa, Université Quisqueya, SOIL has conducted experiments relating to Konpòs Lakay's nutrient content and impact on various crops, greenhouse gases, and other environmental factors.

Every batch of Konpòs Lakay is tested throughout the treatment cycle according to national and international laws, regulations, and standards, and is guaranteed to be safe for agricultural use.

SOIL's Ecological Sanitation

The Process

Konpòs Lakay is part of SOIL's Ecological Sanitation cycle. It is made from treated human waste and agricultural byproducts, primarily sugar cane bagasse and peanut shells. Instead of considering these materials as "waste" and allowing them to contaminate the environment, SOIL safely recycles the nutrients so that they can go back into the soil.

Our team of engineers, agronomists, laboratory technicians, and researchers carefully monitor the treatment process, which takes 7-9 months, to ensure that every batch of Konpòs Lakay is of the highest possible quality.
