Title StatementGreenhouse studies on the use of Philippine peats as fertilizer and soil conditioner
General NoteCollege, Laguna: UPLB, 1978. 95p. -(UPLB-PCARR Proj. No. 338)
Summary, Etc.Experiments were conducted to evaluate Philippine peats as fertilizer. The peats gathered and used were classified as sedimentary peats. They were relatively well decomposed and contained high percentage of nitrogen (N) but had poor water-holding capacity. About 43 M cu m peats deposited in Lake Buluan in Central Cotabato contained on the average, 48% and 2.2% organic matter and nitrogen respectively, and were able to supply a maximum of 40 kg each of N, P205 and K20 to a crop planted immediately after its application. Application of these peats was found best one week after planting at the rate of 10-20 t dried matter/ha. Meanwhile, about 50 million cubic meter peats deposited in Basey, Samar under greenhouse condition were able to supply a maximum of 40 kg each of N and K20 to a crop planted immediately after its application to the phosphorus-sufficient soil. Best results were obtained when the peats where applied during planting time at the rate of 15-20 t dried matter/ha. These peats however, could be applied in phosphorus-deficient soils when supplemented with chemical phosphorus fertilizer
