Tomatoes are known for their human health benefits. Tomato producers use chemical fertilizers to increase tomato production levels. However, the use of organic fertilizers such as digestate can achieve satisfactory yields while sustaining the soil environment. In this tomato study, the effect of three dilutions of digestate (25%, 50% and 75%) on plant height, leaf area and fruit number were compared to NPK 15 15 15. The 50% dilution of digestate had the most beneficial effect on the plants at the end of the experiment.
