[0054] At least one sensor measures the fertilizer concentration (10) in the mixing tank, connected to the fertilizer concentration adjustment pump of the fertilizer tank to control the fertilizer concentration. If the concentration is lower than the set range, the fertilizer concentration adjustment pump will stop operating. If the concentration is lower than the set range, the system checks if the mixing tank's circulation pump is operating. If it is, the fertilizer concentration adjustment pump will add fertilizer to the mixing tank to adjust the concentration to the set range. If the circulation pump is not operating, the fertilizer concentration adjustment pump will stop operating. At least one sensor also measures the fertilizer concentration (10) in the nursery bed (1) and growing bed (2). If the concentration is lower than the set range, the fertilizer concentration adjustment pump will stop operating. If the concentration is lower than the set range, the fertilizer concentration adjustment pump operates with the mixing tank. The mixed fertilizer in the mixing tank is supplied to the nursery bed (1) and growing bed (2) according to the set conditions. If not within the watering period, the fertilizer concentration adjustment pump will stop operating. If within the watering period, the fertilizer concentration adjustment pump will operate according to the set conditions.

[0055] Additionally, at least one sensor measures the fertilizer concentration (10) in the mixing tank, connected to the pH adjuster pump of the fertilizer tank to control the pH level. If the pH level is within the set range, the pH adjuster pump will stop operating. If the pH level is not within the set range, the system checks if the mixing tank's circulation pump is operating. If it is, the pH adjuster will add pH adjuster to the mixing tank to adjust the pH level to the set range. If the circulation pump is not operating, the pH adjuster pump will stop operating.

[0056] At least one sensor also measures the fertilizer concentration (10) in the nursery bed (1) and growing bed (2). If the pH level is within the set range, the pH adjuster pump will stop operating. If the pH level is not within the set range, the pH adjuster pump operates with the mixing tank. The mixed pH adjuster in the mixing tank is supplied to the nursery bed (1) and growing bed (2) according to the set conditions. If not within the watering period, the pH adjuster pump will stop operating. If within the watering period, the pH adjuster pump will operate according to the set conditions.

[0057] Figure 11 shows the components of the watering system in one embodiment of this invention. The plant management system is also equipped with at least one sensor for the watering control unit (11) connected to the watering pump, used for watering the nursery bed (1) and growing bed (2) connected to the watering pump, controlled by the processing and control unit (3) according to the set conditions.
