Zwart Systems - AdeptAg products

Flood floor irrigation systems are the best option for growers producing seasonal crops, looking to reduce labor costs and improve crop quality. Enjoy consistently great crops and a virtually maintenance-free growing system. Flood floor irrigation technology has changed immensely over the past 20 years. Advances in concrete technology allow for a shallower profile on the floors to create greater uniformity. Delivery and filtration technology have also improved. Ask any greenhouse grower with a concrete flood floor built within the past 10 years and they will agree that they save a large amount of labor and enjoy consistently great crops and a virtually maintenance-free growing system.

At Zwart Systems, we offer multiple drip irrigation systems to help save nutrient and water consumption by placing water at the root zone, maximizing resources and minimizing labor. If you have done irrigation work around your greenhouses, you likely have had to deal with poly pipe. One of the downsides when dealing with poly pipe for drippers is punching the holes to your desired spacing before inserting the drippers. Let us take your labor out of the equation. At Zwart, we can punch the poly pipe to the spacing you need, and for an additional fee, we will insert the drippers for you, providing a precisely punched poly pipe with no downtime for your operation.

At Zwart Systems, we are proud to offer a custom solution to every grower`s unique requirements. Our Perfect Rain boom irrigators offer the most uniform and versatile irrigation and mist available. Zwart Systems has been manufacturing irrigation booms for over a decade. Our booms are made of the highest quality North American materials and are built to last. Double rail booms are very cost-effective and deliver 99% irrigation uniformity. Zwart Systems offers two control platforms to manage our booms or any other competitors’ booms if that is your desire.

Overhead hanging nozzle assemblies from Zwart Systems are a low-cost option for introducing irrigation that can provide a range of styles from mist to droplet for all growing areas. Hanging nozzle assemblies are a simple, cost-effective system to introduce overhead irrigation to growing areas. There are many nozzles to choose from that can provide anywhere from a mist for propagation to an irrigation style droplet. Overhead nozzle systems could water a 24’ wide x 120’ long greenhouse of 4” pots in 20 minutes with 95% consistency. It could be used to disperse Nematodes or to add humidity to a young poinsettia crop. We draw from both Netafim and NaanDan systems to provide the best result for the grower when we design a project.

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.
