LSD Offers Free Training on Tricho and Legume Inoculant Production

By Aurora M. Manalang – February 20, 2012



Composting is an alternative procedure for converting on- farm organic waste materials into a farm resource. However, farmers in many parts of the world and even in developing countries are unable to benefit from the composting opportunities being extended to them, because they lack awareness on efficient and expeditious labor-saving technology.

Soil Inoculant and Trichoderma

The growing concerns relating to land degradation, the inappropriate use of inorganic fertilizers, atmospheric pollution, deteriorating soil health, soil biodiversity and sanitation have rekindled interest in organic recycling practices such as composting on the production of organic fertilizer- as it enhances soil fertility, improved soil health and increased agricultural productivity. With the discovery of Trichoderma harzianum, Compost Fungus Activator (CFA) by Dr. Virginia C. Cuevas from UPLB in 1986, the composting method has been simplified, minimizing labor inputs. Tricho hastens the decomposition of various agricultural wastes in just 3-4 weeks. By using Tricho, the farmer reduces the amount of inorganic fertilizer that he needs by 50%, thus lowering his production costs and continued use can result to increased yield based on nationwide trial on Modified Rapid Composting Technology.

The BSWM adopted the technology for many years. It has even simplified the techniques of mass producing pure cultures of Tricho, more so, the manner of composting the wastes. Majority of the Regional and Provincial Soils Laboratories in the country including the recipients of OFPP Tricho Laboratory Establishment Project have been trained on Tricho Production and in the process of rapid composting of wastes.

On the other hand, legumes inoculants are biologically prepared materials in a compounded soil mixture containing a pure culture of nitrogen-fixing bacteria or Rhizobia which symbiotically fix atmospheric nitrogen into a form that leguminous plant can assimilate. The use of legume inoculants ensures the introduction of effective N-fixing bacteria which reduces or eliminates the need for the application of N-fertilizer. Inoculation also increases the grain yield and quality of crops.

Legume inoculation is a way of assuring that the Rhizobium strains is present in the soil, appropriate for the seed to be planted at the proper time and number sufficient to assure a guide and effective infection and an efficient subsequent N-fixation. Inoculation is usually accomplished by treating the seed or the soil with a mix of selected strains of bacteria and carrier called inoculums.

Free training on Tricho and Legumes Inoculants Production can be offered to interested individuals, groups, students, farmer’s cooperatives, technicians, crop growers, and entrepreneur. Request can be coursed through the office of the Director - Dr. Silvino Q. Tejada, CESO III.
