Coffee’s inherent quality improves when grown at higher elevations. Therefore it is beneficial to have an accurate map indicating the elevation of each plot in the Subak. The information provided by such a map can then assist with decisions on where to plant specific coffee varietals and/or cultivars, as each will have an optimal elevation where it will produce its best quality cherries.
- Identified plots with nutrition deficiencies, which can be addressed through more efficient fertilizing.
- Identified plots affected by coffee leaf rust (CLR)
- Clearly delineate coffee varietals and cultivars in the field so pickers know what is planted where and can pick accordingly
- Improve genetic stock of entire Subak by planting improved quality varieties and cultivars
- Leverage higher elevation zones by slowly replacing commodity-grade trees with specialty-grade trees
- Existing variety and cultivar identification
- Variety and cultivar purchasing and placing
By identifying the location of all plots, farmers can then make variety/cultivar purchasing and planting decisions based on the elevation of the plot. The Subak can also strategize how to organize quality tiers into marketable products. For example, all coffee grown below 1000 MASL could be marketed as a lower-priced, commercial-grade coffee while coffee grown between 1000 – 1099 MASL could be marketed as a middle-tier workhorse coffee and everything grown above 1100 MASL could be processed and marketed as microlots, sold at a premium.
In the process of mapping plots, trees can be inspected for various problems such as nutrient deficiencies, pest and disease issues, etc. Once the problems have been identified, they can be addressed.
