Master's thesis in two parts: theoretical and practical. A literature review concludes that wastewater sludges can be used efficiently in forest fertilization. They give better yields, in the same manner as chemical fertilizers. Negative effects are negligible. In the second part, larches seedlings were grown on sand in a greenhouse and fertilized with different quantities and frequencies of anaerobic sludge. Positive experience that agrres with theory: better yields.
