The aim of this study was to evaluate a production of Gambier plant cultivated in critical land in Pakpak Bharat Regency, North Sumatra Province, since January to October 2013. Descriptive analysis was used to evaluate the progress of Gambier plant growth in relation with the status of soil and chemical substances in land. The study took 12 points of sampling to composite four replicates with the depth of (0 to 20) cm and (40 to 60) cm. Providing of dolomite to raise the pH of the soil has not been done because the pH of the soil is still suitable for the growth and production of Gambier. The interchangeable of K content which belongs from the moderate to high on the top layer and low in the bottom layer. Providing phosphate, Ca, and Mg fertiliziersis absolutely necessary because the P-levels are available, although P-total as well as the levels of Ca and Mg can be exchanged into very low.id
