Physicochemical analysis of organic and inorganic rice farm soils in Dumingag, Zamboanga Del Sur, Philippines

Rhivee Mae H. Conol*

This study compared the physical and chemical parameters of the organic and inorganic rice farm soils in Dumingag, Zamboanga del Sur during 2015-2016. It sought answers to the following questions: Moisture content, pH, particle density, and water holding capacity. 30 samples were collected and analyzed at Soil and Plant Analysis Laboratory, Central Mindanao University (CMU) – Maramag, Bukidnon. Organic and inorganic rice farm soils in Dumingag have similar soil conditions, making organic farming more advantageous than inorganic farming. Fertilizers such as farmyard manure, animal manure, vermicast and synthetic fertilizers will be increased to improve soil condition. Analysis of physical and chemical parameters will be conducted in different periods of planting seasons to determine fertilizers and nutrients needed to increase yield. Other researchers should conduct studies to determine micronutrients and cost and return of organic and inorganic farming systems.
