Water restoration for container nurseries
A container nursery lives on its irrigation water, and much of it is stored and recycled: captured runoff, a holding reservoir, a return that recirculates. Water that sits warm and still goes flat, and the crop reads it as slow, uneven growth and emitters that clog. The reservoir sets what the whole yard receives.
The problems we see on your water
What Alchemal installs and takes responsibility for
A container yard draws almost everything through one point: the irrigation reservoir. Water held there warms and settles, and a warm, still basin loses its dissolved oxygen (the oxygen dissolved in the water) and stratifies into a flatter, oxygen-poorer bottom layer, which is usually the layer the lines draw from. Recycled runoff adds nutrients and biology that make the basin work harder still. The water leaving flat arrives at the root zone (the water and medium around the roots) already short, and it seeds the algae and biofilm that foul the drip downstream.
Nanobubble oxygenation holds dissolved oxygen through the full depth of the reservoir and carries it down the line with every watering, adding nothing else. We baseline the basin before sizing anything, top to bottom and across the day, install the system matched to it, and Stewardship logs the oxygen against a baseline taken before any commitment. Where the real limit is nutrient load, sediment, or filtration rather than oxygen, the assessment says so. The N-Series unit is matched to the site, with a published target price band, and what we measure and how is published, so the reserve in your reservoir is a number you can check.
Proof from container nurseries
The first installations for this audience are being instrumented now, and their case files publish when the record is worth reading. The methodology is already public: what we record, how we calibrate, and how we report what didn't move.
From your first note to the assessment
- You describe the water. A specialist reads it, replies with a plain answer, and says whether an assessment makes sense.
- Your water goes on the schedule. The first assessments and installations are being scheduled now; requests are answered in the order they arrive.
- The assessment puts a baseline on paper: dissolved oxygen top to bottom, clarity, the condition of the sediment, and a plan with a prediction attached. If oxygenation isn't the right fix, the report says so.
Questions nursery growers ask
Do you treat the reservoir or every line?
We hold oxygen in the reservoir, which is where the whole yard draws from, so the water leaving it carries a reserve down the lines. Clearing and filtering the lines stays your maintenance work; the reservoir change slows how fast they foul again.
How do you size a system for our reservoir?
The assessment baselines dissolved oxygen top to bottom and across the day, since a stored reservoir stratifies, then sizes to hold a reserve through the warm, still weeks. We measure the basin before sizing, and we will not quote an undersized unit to win on price.
We recycle runoff already. Does that change anything?
Recycling saves water and returns nutrients, and it also returns whatever the runoff carried, so the reservoir works harder to hold its oxygen. The baseline reads how flat the recycled water runs, so the reserve is sized to the load you actually recirculate.
