Helping trees survive hostile soil conditions


The Department of Environment and Natural Resources (DENR) has developed a promising plant microorganism that can help trees survive hostile soil conditions.

According to Dr. Henry Adornado, acting director of the DENR-Ecosystems Research and Development Bureau, this plant microorganism called mycorrhiza is known to benefit plants by making sure that plants and trees survive any soil condition.

It is also cost-effective, environment-friendly and sustainable. Once it is inoculated in the roots, it will stay in the roots of plants throughout its lifetime.

“This technology, commercially known as the Hi-Q Vam 1 is helping trees to grow much faster, doubling the rate compared to those without mycorrhiza,” Adornado said.

It was in 2000 when ERDB’s mycorrhizologist, Dr. Evangeline Castillo, led the collection of different species of mycorrhiza all over the Philippines in search of the right species that could be used in environmental rehabilitation programs.

According to Castillo, ERDB’s field experiments revealed that mycorrhiza plays a “conduit role” in poor soil conditions by actively spreading its roots to obtain the needed nutrients of the plants to survive.

Thus, in 2012, it has been patented as a utility model by the Intellectual Property Office (IPO) of the Philippines.

“Since many of the marginal areas such as upland, grassland, mined-out and other areas in the country have been degraded due to unsustainable farming, grazing and ore extraction activities, the mycorrhiza that is naturally available in many plant species have been lost from the soil,” Castillo said.

Hi-Q Vam 1 is being used in production of quality planting materials for the National Greening Program (NGP) which aims to plant 1.5 billion trees in 1.5 million hectares degraded areas in the country from 2011 to2016.

For 2015 and 2016, ERDB will produce 411 metric tons (MT) of Hi-Q Vam 1 under the supervision of Carmelita Mojica, a research specialist at ERDB. This bio-fertilizer will be inoculated in the planting materials for the NGP to ensure the high survival of planted seedlings.

According to Angelito Exconde, assistant national coordinator and executive officer of NGP, mycorrhiza serves as cheap source of promoting plant growth.

Even with an upfront cost of 20 centavos per application of mycorrhiza per tree, the investment pays off as trees survive and generate income over the years.

To address the need for Hi-Q Vam 1 inoculation in NGP’s quality seedlings, ERDB has constructed facilities for the production of mycorrhiza.

These are located at ERDB’s production facility at the Science and Technology Park of the University of the Philippines in Los Banos, Laguna; Ramon Magsaysay Technological University in Botolan, Zambales; and Bohol Island State University (BISU) in Bilar, Bohol.

With these facilities, ERDB can produce 500 to 1,000 MT of mycorrhiza annually for around four million seedlings.
