RemineralizersJanota59 provided some excellent links to detailed information on the remineralizer market place in Brazil. Here is a Google Translate version of the Portuguse text:
Remineralizers are considered to be multi-nutrient sources. In addition to this characteristic, the main advantages of using remineralizers are related to the increase in the efficiency of the use of nutrients by crops, the improvement of the soil and its biological activity. Added to these advantages is the development of new regional productive chains for the production of inputs for agriculture, involving mining, processing and transportation of remineralizers.
The limitations are limited to the maximum production costs and the distance of transportation of the remineralizers from the mine to the agricultural area. The effects on the soil are faster the finer the remineralizer, but the cost of producing very fine particles increases proportionally. The logistical limitation depends on the composition of the remineralizer, due to the need for application in high doses to obtain the desired effects in relation to the supply of nutrients and soil improvement. This logistical limitation can vary from 100 to 500 km from the mine, depending on the characteristics of the remineralizer, considering road transport.
This assessment would appear relevant to the K-Forte product. It would also appear relevant to traditional KCl potash mined 2 km underground in Canada, processed into its final pink crystal form, and shipped in bulk by rail across Canada to the coast, and then by sea to Brazil. I would be keen to see the relative transportation costs of the two products as they make there way to various farming locations across Brazil
