The Department of Environment and Natural Resources (DENR) is boosting its production of bio-fertilizers by 55 percent in support of the government’s National Greening Program (NGP).
Some 155 tons of bio-fertilizers will be made this semester or 55 tons higher than what was produced during the same period last year, according to the DENR’s Ecosystems Research and Development Bureau (ERDB).
ERDB is using “mycorrhizal” technology in producing fungus-based fertilizers, which main component is a nitrogen-fixing bacteria species called “vesicular arbuscular mycorrhiza.”
Mycorrhiza is known to promote fungal infection in the root area of a plant, induce root growth and improve transfer of water and nutrients to the host plant.
“A total of 155 tons are to be distributed to 16 regions from January to June 2013, with a maximum of 10 tons per region,” ERDB Director Portia Lapitan said in her memorandum to DENR Secretary Ramon J. P. Paje.
The production of the bio-fertilizer was first pegged at 100 tons in May last year, when it entered into a rpartnership with the National Institute of Molecular Biology and Biotechnology of the University of the Philippines-Los Baños (UPLB-BIOTECH).
Lapitan noted that the production capacity of the UPLB-BIOTECH has been hitting 25 tons per month since last December.
Dr. Evangeline Castillo, ERDB science research specialist and project leader for the mycorrhizal production, said some 43 tons had already been distributed to various DENR field offices as of March this year.
Castillo said satellite nursery facilities will be constructed this year to mass produce the bio-fertilizer by the DENR for the next four years of the NGP’s implementation as well as for possible public consumption after 2016.
“The project hopes to produce about 500 tons of mycorrhiza by the end of the year from the three satellite nursery facilities established in Laguna, Bohol and Zambales provinces,” Castillo said.
She added that the mass production of bio-fertilizers was in compliance with Paje’s order to maintain an 80 percent survival rate of planted seedlings under the NGP.
The DENR is also planning to put up another mycorrhiza facility in Agusan del Norte to supply the bio-fertilizer requirements of the NGP’s implementation in Mindanao, Castillo said.
ERDB’s facility inside the UPLB is already in production mode of the bio-fertilizer in preparation for the supply needs for the second semester while the construction of other facilities is now in full swing.
These facilities are located in Bohol Island State University in Bilar, Bohol; Ramon Magsaysay State University in Botolan, Zambales; and Caraga State University in Butuan City, Agusan del Norte.
According to Castillo, using mycorrhiza as fertilizer is more practical because of its unique characteristics that boost root growth.
“With the limited availability of water particularly during long dry season, mycorrhiza increases the plant’s tolerance to drought,” Castillo said.
She said biofertilizers were also effective even in hostile environment like mine waste areas and mine tailings site, citing studies which show that mycorrhiza has unique mechanisms that sequester heavy metals in the soil, thus increasing the plant’s tolerance to toxicity of the metals and minimizing their transfer to the plants treated with the bio-fertilizer.
