PSPs is made on site and on different stands in order to represent the condition of the Educational Forest of Wanagama I. one that can be studied in PSPs is potassium content of soil. Potassium is the third most important element after N and P for plant.

From observation to potassium levels of soil under the stands of teak, legaran, and mahogany in the educational forest of wanagama I, it included in the criteria is very low at <0.1 me/100gr. Nutrient levels of potassium in each stand is on Teak 0.003 to 0.020 me / 100gr, on mahogany 0,005-0,013 me/100gr, and on legaran 0,020-0,038 me/100gr. This shows the soil at educational forest of wanagama I in the stand of teak, mahogany, and legaran was very lack of nutrient potassium, and also at educational forest of wanagama I needed treatment of potassium fertilization for plants to grow well.</description><publisher>[Yogyakarta] : Universitas Gadjah Mada</publisher><date>2014</date><type>Thesis:Thesis</type><type>PeerReview:NonPeerReviewed</type><identifier> , ARI ABRIYANTO and , Daryono Prehaten, S.Hut, M.Sc.
