Microp BG - Biofertilizer / Soil Improver

Biofertilizer for Rice

MICROP BG is used to supplement urea usage in flooded rice. Over 30 years of research has shown that nitrogen-fixing cyanobacteria produce significant increases in rice yields by supplying nitrogen in a slow-release, plant-available form.

MICROP-BG's dormant cyanobacteria cells are applied with aerial or ground spray equipment immediately following permanent flood, up to the 1/2 inch internode movement. Once MICROP-BG is applied, the cells come out of dormancy and begin to grow rapidly. As the photosynthetic cyanobacteria develop, they fix nitrogen, deposit valuable organic materials into the soil, and provide oxygen to the submerged rice roots.

This natural, time-release process offers rice-growers an ecologically sound method to enhance productivity and reduce inputs.


Technical Data Sheet

PRODUCT PURPOSE: Grown as a companion crop which produces unmanipulated vegetative plant residues for soil and crop improvements MICROP-BG is composed of nitrogen-fixing microalgae which serve as a biological source of nitrates in flooded rice fields.

PRODUCT DESCRIPTION: Cyanophyta single celled plants in a dry mixture with a density of no less than 320 million living plant cells per gram.

GROWTH CYCLE: Seeded into the flooded field at the rate of one ounce per acre (70 g/ha). The plants grow and colonize in the flooded rice field by cell division. MICROP BG reaches maturity (begins to produce available nitrogen) in about 15 days under average conditions and will continue to grow for up to 60 to 90 days if undisturbed.

APPLICATION TIME: Immediately following permanent flood of the rice field, up to the 1/2 inch internode movement.

APPLICATION METHOD: Suspend dry product material in water and apply with any liquid spray equipment (aerial or ground).

HERBICIDES: Once seeded in the flooded rice field MICROP-BG will not be harmed by herbicide application.

ALGICIDES: Avoid use of algicides which may be active in the floodwater during the growth phase of MICROP-BG. Ask your chemical dealer about length of residual algicide activity.

TANK MIXING: Soil Technologies does not recommend that MICROP-BG be mixed with other chemical products. The company has found, however, that MICROP-BG cells remain viable when mixed with certain chemicals and fertilizers. Before attempting to tank mix, consult Soil Technologies technical staff.

SHELF LIFE: Expiration date is 1 year from the date of packaging.
