The paper concerns the profitability of PK and NPK fertilization in mature spruce stands on drained peatland in South Finland.
The profitability was found to be very high in plots given 200 kg/ha or 400 kg/ha of PK fertilizer. The other treatments also gave at least a satisfactory economic result. On average, PK fertilizations was noticeably more profitable than NPK fertilization.
