Organic Fertilizer:

"In nature nothing is created, nothing is destroyed, everything is transformed" A. Lavoisier

With the use of organic fertilizers farmers can reduce the use of external inputs and increasing the efficiency of community resources, while protecting human health and the environment.

Victoria organic fertilizer production and use of agro-waste at the Mill and Coffee.

Mill CoopeVictoria, receives and processes more than 80,000 acres of coffee that generate between 38% and 40% of solid waste, coffee bean chaff ( Broza) of processed coffee.

Years ago, commercial waste from the manufacture of sugar, which are mainly sugar cane gur and ashes ended up in the streams of rivers contaminating them chemically, physically and biologically. But since 1986, CoopeVictoria began the first experiences on composting; anticipating what would come in the future, in terms of utilization of organic waste and a rigorous conservation law

All this forced to seek a reasonable use to these sub-products in order to warrant investment in collection systems, transportation and handling. That was how, that year, the gur, ash and coffee bean chaff, went into the composting process to give rise to VICTORIA ORGANIC FERTILIZER.

Manufacturing Process:

The fertilizer manufacturing process is done in a lot of 2 ha farm of the Cooperative, open-pit operation basically consists of mixing the three residues together with a natural process of aerobic decomposition.

The ash is separated from the wash water boiler through gravel filters.

The gur is the residue of the process of clarifying the mixed juice, and consists of a mixture of fiber, sucrose, land and some elements such as nitrogen, phosphorus and calcium.
The coffee chaff is also transported in carts to the composting area. There, parallel mounds of 150 meters long, three meters wide and 1.5 meters high are formed by layers of such materials. This procedure seeks to maintain a volume-volume affinity of 30% “Cachaza”, 50% chaff and 20% ash.

These mounds, which weight ranges from 200 to 250 tons each, go through a period of aerobic decomposition for two months. During this time they are removed every 4 days to help the process of oxygenation of the microorganisms and to control the temperature that should not exceed 60 ° C. By this means, an organic material suitable for agricultural use is obtained.

The chemical analysis of compost has the chemical characteristics below .

In this analysis, you may notice that the material is rich in organic matter, has a good rapport C: N and also has good content of nitrogen, phosphorus, potassium and calcium. From micronutrients, iron content highlights.

In the area of influence of Cooperative Victoria, it has been has verified the positive effect of the use of our fertilizer on crops of sugarcane, coffee and vegetables. Currently its use has been expanded to other crops across the country.

Victoria Compost is available in presentations of 2 kg and 40 kg packaging bags
