Zwart Systems - AdeptAg products

One way in which proportional systems can fall short is in human error—stock solution can be made inconsistent from batch to batch. Injectors can fall out of calibration over time and irrigation will continue to run without alarm warnings when the stock solution is weak, strong, or empty. A second way proportional injectors can be thrown out of calibration is a result of wear and tear on the equipment caused by fertilizer viscosity in the stock solution. Cyclone Pump Sets are computer-controlled units that consistently deliver temperature compensated EC/pH monitored fertilizers, track progress, graph history and send alarms when EC/pH set points are not achieved.

Reliable and low-cost, Dosatron injectors are simple to operate and rely only on your water system’s pressure to provide accurate injection of your pre-mixed fertilizer solutions. Many growers want to be able to fertilize just a bench or an area or perhaps use a fungicide on only one crop. This can be difficult if your injection system uses a common mainline to supply all areas. Some growers have mounted proportional injectors on hand-carts with a pail for supply or used a wagon but if you ever pulled on a hose and watched your cart tip over and your injector crack as it hits the ground, you would know why we developed a Dosatron Cart that will last a lifetime. Dosatron carts are for fertigation on the go. From single units to comprehensive systems, Dosatron has been the proportional injector of choice for Zwart systems for over 25 years. Discover the difference Dosatron can make in your greenhouse, garden center, or nursery.

pH is an important detail in plant nutrient uptake. Zwart Systems has designed a pH loop system to help growers in correcting pH in farm irrigation. If your farm or greenhouse irrigates using rainwater or lake water, you may have water that is low in bicarbonates. If this is the case, then often fertilizer selection will help you reach your desired pH level. If your farm irrigates using well water or pond water, the bicarbonates can be high, and it may be a challenge to correct and maintain at a proper pH level. When bicarbonate is high it is necessary to lower the pH by adding an acid. When the pH value and the desired set point are too far apart, and bicarbonate level is high, multiple dosings of acid may be required. If dose levels are too strong you can go over the ‘pH cliff’. Circulating water in a tank with a pH loop is the safest way to maintain the correct pH set point.
