BSWM conducts a seminar-workshop on Zinc in soils, interaction and management for rice nutrition

Zinc is the most common micro-nutrient disorder in wetland rice. Its deficiencies mainly occur when soil pH is high, when there’s a presence of high organic matter in soil, when soil is calcareous or chalky with high bicarbonate content, and when soil is intensively cropped. Paddy soil under prolonged submerged condition cause Zinc deficiency. Zinc amelioration is widely practiced in Zinc deficient areas. Zinc sulfate is a commonly used ameliorant that is applied in soil as broadcast or in seedbed. Since, it is an essential nutrient for rice, it is important to know other conditions that affect its deficiencies.

In this line, the Department of Agriculture’s Bureau of Soils and Water Management under the leadership of the OIC-Director Angel C. Enriquez, through the Soil and Water Resources Research Division headed by Dr. Edna DL Samar, organized and conducteda one day Seminar-Workshop on Zinc in Soils Interaction and Management for Rice Nutrition. Resource Speakers include Ms. Evelyn F. Javier from the Philippine Rice Research Institute (PhilRice); Ms. Angelita C. Marcia of BSWM; Dr. Johnvie B. Goloran and Mr. Francis Hennel C. Rubianes of the International Rice Research Institute (IRRI); and Dr. Annabella B. Tulin of the Visayas State University. They discussed different topics on zinc dynamics in soil, zinc technology experiences and research results.

Participants include the DA-RFO’s R&D and Rice Program Focal Persons; DA Regional Soils Laboratory Staff; representatives of the Philippine Council for Agriculture, Forestry and Natural Resources Research and Development (PCARRD), Bureau of Agricultural Research (BAR), Bureau of Plant Industry (BPI), PhilRice, International Rice Research Institute (IRRI), Fertilizer and Pesticide Authority (FPA), Philippine Nuclear Research Institute (PNRI) and the BSWM Technical Staff. The participants are expected to gain increased awareness on Zinc in soils, interactions and management for rice nutrition; technology awareness from experiences and researches; improved cultural and nutritional practices for Zinc deficient areas; and adopt possible technology for Zinc management. A plenary followed which provided the opportunity for the participants to identify the R &D gaps in Zinc dynamics and amelioration technology.
