To maintain the final grain quality, the harvested coffee cherry are stored immersed in water, to adjust harvested volume and the processing capacity. This study reports some chemical and biochemical characteristics of the water left after storage, to assist decision making for its treatment for river discharge or for agricultural use such as fertilizing. Coffee cherries of different characteristics and origins were used, and BOD, COD and concentration of P, N, K and Na was determined after the storage period of 1 to 5 days. The data showed that the concentration of the nutrients in the immersion water is related to fruit maturation and, in general, also to the degree of cherry deterioration, and this water has potential for fertirrigation.
