The Dirty Work: Soil Revegetation Case Study

Apr 11, 2017
BioFlora Improved Soil Revegetation

The following data has been compiled over several trials that were conducted throughout Indonesia with the BioFlora product Humega.

Humega®, is an organic, biologically active, humate product. It works to increase soil aggregation, improve water infiltration, improve root development and stimulate microbial activity in the soil.

This product was tested on soils that had been mined for tin and coal and were in need of a revegetation program. These soils had a low pH (3.8-4.6), had very low organic matter, low water holding and cation exchange capacity, had the potential for iron deficiency, had a decreased microbe population and were expected to perform in high temperatures. To alleviate these issues and revitalize these soil, BioFlora utilized the following program:

Application Program

Humega: Broadcast or banded
10 gals / acre (100 lts / ha)

Granular NPK Product: Broadcast or banded
36 lbs / 1,000 sq.ft (16 kg / 1,000 sq. ft.) or
750 lbs / acre (840kg/ ha)

*Application is for individual plant

Humega: 20 gals (75.7 lts) blended with 100 gals (378 lts) of water. Apply 16 oz. (0.5 lts / ha) of blend per plant

Granular NPK Product: Apply 2 – 3 ozs (0.06 – 0.09 kg) per plant
