Research Title Nutrient and Water Dynamics in Muyong-Payoh Systems in Amganad, Banaue, Ifugao
Research Personnel Leader:
Dr. Damasa M. Macandog

Research Duration Start:
14 December 2011
13 December 2013
Research Location Amganad, Banaue, Ifugao
Research Description The nutrient and water dynamics in the “muyong-payoh” system in Banaue, Ifugao was determined by quantifying the essential nutrients present in the soil and water run-off from the “muyong” forest; the changes in soil fertility level of “payoh” at various times after the application of sunflower leaves during decomposition and throughout the rice growing season; to quantify the rice plant nutrient content (leaves, stalks, grain) at harvest. The nutrient contents in soil, water and vegetation in the “muyong-payoh” system is very dynamic. Results have shown that essential nutrients vary in space and time in the system. The soil organic matter and exchangeable K contents are higher in the “muyong” forest that in the “payoh” plots. Soil organic matter content of soils in “payoh” terraces increased with increasing distance from the “muyong” forest while soil available P and exchangeable K decreased with increased distance from the “muyong” forest. The soil nutrient contents were lower at harvest stage compared with soil nutrient contents at transplanting stage. Plots with sunflower had higher soil available P at harvest stage than at transplanting stage.
Research Objectives The project will be able to generate quantified and improved nutrient management strategies of irrigated upland-rice farming systems (payoh) in Banaue, Ifugao. The data and information generated by the project will be an important input in local policy formulation and development of information materials to help improve the socio-economic status of indigenous farming communities in Northern Luzon.
