Objectives of the Experimentation:
The trial aimed to evaluate the nutritional efficiency of nitrogen (N) and phosphorus (P) in organomineral fertilizer formulations. More specifically, the goals were to analyze nitrogen release dynamics, assess phosphorus efficiency, and perform an N and P balance in the soil/plant system.
The test species was tomato, grown in large pots (28 cm in height and diameter). The pots were filled with a soil (1/3) – sand (2/3) mixture, buried, and equipped with an automated irrigation system (low-flow, with individual drippers for each pot and a timer).
Plant nutritional status was monitored throughout the growing season. Harvesting was carried out in two phases, both in August. Fresh and dry weight, acidity, and Brix degrees of the fruit were measured. Observations were also conducted on the root system.
