• Productive system:
• Rice and maize/corn
• Geographic coverage:

• National

Description

Fosfotal is a biofertilizer whose active ingredient is the native strain of Rhizobium pusense (B02), with a minimum concentration of 1x10⁸ CFU/mL of product.

It serves as a complement to synthetic chemical phosphorus fertilization since it helps reduce the application of phosphorus fertilizers in rice and maize/corn crops by up to 50 %, following a conventional fertilization scheme for these productive systems, i.e., maintaining the application of fertilizers to supply other elements.

It is compatible with the main active ingredients of fertilizers and pesticides used in maize/corn and rice crops, which allows its incorporation into integrated management programs. Additionally, depending on the crop's geographical area, Fosfotal can increase production by up to 6.25 % in maize/corn crops and up to 7 % in rice crops.

Reduces the potential negative environmental impacts caused by applying excessive chemical fertilizer obtaining healthier and safer foods.

The economic impact of losing purchasing power in international markets (devaluation of the Colombian peso against the US dollar) is reduced.

Presentation and dosage

Fosfotal is a concentrated suspension. It is found in a 2-liter polyethylene bag.

Dosage and frequency of application

The recommended dose for maize/corn and rice crops is 1 liter per hectare, which must be divided into two applications, depending on the abovementioned crops.

A premix must be made in 150 liters of water in each application.

Fosfotal is a bioproduct that requires refrigeration.
