    Abstract
    The availability of nutrients plays a role in increasing plant productivity, especially macro nutrients (potassium) and C-organic. The problem that occurs is nutrient deficiency. This study aims to map the spatial distribution of potassium (K) and C-organic nutrients, and also to determine the relationship between these nutrients and the productivity of robusta coffee. The research was conducted from March to May 2023 at PTPN XII Kebun Renteng Afdeling Termite. A survey method based on land mapping unit boundaries was used to collect field data for this study. Mapping of nutrients was made using clustering, so that 42 samples were found to determine the availability of potassium (K) and C-organic nutrients. The results showed that the criteria for potassium (K) were very low to high (<0.1%-1%), the criteria for C-organic were very low to moderate (<1%-2%), and the criteria for pH were acid to neutral (4.5 -7). The availability of potassium nutrient is classified as moderate, the availability of C-organic is classified as low to medium and the availability of pH is classified as slightly acidic to sour. The effect of potassium, C-organic and pH status on productivity is shown by the correlation coefficient -0.85, -0.53, and -0.64. The relationship between potassium, C-organic and pH status on productivity is shown by the regression coefficient R2 = 0.73
