Vertical Farming with Dosatron | Nutrient Dosing System

A Tower Farm is defined by a minimum of 10 commercial-grade aeroponic towers equipped with fully automated irrigation and nutrient-dosing systems.

It is obvious that an aeroponic tower used to grow parsley will use less water and nutrients than a tower dedicated to growing tomatoes. Our fully automated irrigation and nutrient dosing systems supply water and nutrients to each tower on an as-needed basis.

At Agrotonomy, we consider a Tower Farm the analog version of vertical farming. Contrary to conventional hydroponics, no sensor is required, only one nutrient solution is used for all crops, and our irrigation and nutrient dosing systems work with water pressure and gravity.

Our plants receive a meticulously calibrated blend of minerals and trace elements dissolved in water. This ionic nutrient solution includes all macronutrients like nitrogen, phosphorus, potassium and vital micronutrients such as copper, molybdenum, and boron.

At the heart of our farming system lies the Dosatron, a crucial component responsible for precisely dosing the nutrients with water, ensuring the perfect nutrient-to-water ratio.

Here’s how it operates: As water flows into our farm, it passes through the Dosatron, where we set the ratio to 1:300, meaning that for every 300 liters of water used in our farm, one liter of Nutrients A and B is seamlessly mixed in. The Dosatron operates without electricity since it is powered by water pressure in conjunction with an ingenious piston technology.

The nutrient-enriched water then goes into a gravity tank which sits 3 feet off the ground, where, driven by the force of gravity, it automatically fills the Aeroponic Towers on an as-needed basis through a float valve mechanism, precisely delivering the nutrients to our plants, ensuring optimal growth, yield, and a high nutrient density.

During the hottest summer months, we change the nutrient-to-water ratio to 1:400 (1 liter of nutrient solution mixed in 400 liters of water). In fact, when the ambient temperature rises, plants need to drink more water but don’t need to absorb more nutrients. This is why we increase the ratio to provide more water for the same amount of nutrients. Changing the nutrient-to-water ratio on the Dosatron units is straightforward and takes 1 to 2 minutes.

This nutrient-dosing system is perfectly designed to serve up to 150 towers effortlessly. For larger projects, we recommend utilizing multiple Dosatron units/stations to ensure redundancy and, therefore, a backup.

The Dosatron nutrient dosing technology requires very little maintenance, and it is very durable and sturdy. It is by far the most stable nutrient-dosing option available.

We have set up Tower Farms in over 50 countries on 6 continents using Dosatron technology. We have never received a complaint from any of our customers or partners regarding their nutrient-dosing system.

We do not have any vested interest in recommending Dosatron. We are not commissioned on any equipment related to the irrigation and nutrient dosing system that we resell at cost as part of our Tower Farm turnkey solutions.
