Why is agritechnology crucial for growers and consultants?
There are a number of issues on people’s minds in this industry— issues that crop-level insights can help resolve. Petunia distortion and pansy mottle syndrome, for example, are environment-related, but the industry has never really found a fix or a way to control and prevent them. These issues would pop up some years, but not others, and there was never any reliable way to really predict them. That’s been one interesting challenge.
One customer, for example, had a particularly bad problem with petunia distortion last year, which resulted in high levels of waste and product loss. I worked on a project with them this year, which showed both the importance and limitations of some technology. I’d use their computer data, go into the nursery, download the information— export into PDF, analyze, and send it back to them. Needless to say, this was a difficult and clunky way to work. But it did underscore the point that regular contact on environmental conditions is important. We could see the changes to the environment, see the effect of those changes in the environment on the crop, look at the weather going forward, and repeat every week. That kind of regular monitoring informed our ability to change the greenhouse conditions to suit the outside environment: drop temperature when it gets cold, raise temperatures to control VPD or humidity when it gets warm. It’s all about keeping plants active and understanding how they respond to the environment on an ongoing basis. As soon as I saw the 30MHz system, I saw the advantage that it would give to this sort of consultancy. I saw opportunities for this product, but I needed some examples. So I approached Fargro, who agreed to allow me to trial this with some customers. Newey Roundstone is the first.
How are you working with the 30MHz platform at Newey Roundstone?
We’re still just finding out how it all works, but we’re already seeing the benefits in a short time. We’re seeing plant response on a continuous basis, monitoring leaf temperature (which we could never monitor before), VPD at crop-level, RH, AH, and HD. We can make changes to the environment with this kind of information. We can change when irrigation happens, change screen settings. Monitoring is helping us understand how to prevent loss: we’re understanding the stress that may cause pansy mottle syndrome in pansy production.
Some will say there’s no replacing “looking at the plant.” Where do remote monitoring and crop analytics fit with more traditional approaches to horticultural consulting?
It’s not about replacing looking at the plant, or going into the greenhouse. It’s about adding a new level of context and insight that we previously didn’t have. The problem with only looking at the plant is that you’re just seeing the snapshot, the plant at a given moment. You don’t see what it has experienced, or what it will experience. I feel that we’ve never been able to truly understand what’s going on with our crops because we’re drawing conclusions based on single moments, and we risk making the wrong judgements. Analytics from live data give us more support in our decisions, allowing us to look backwards and have more information moving forward. That’s the big benefit.
For example, if you walk into a greenhouse and the plant is wet— it’s easy to assume you might be overwatering. But you haven’t got the context of what’s happened in the past seven days. If you have crop-level data, you can see if the plant’s been stressed, you can look at the VPD. It’s not about replacing looking at the plant— we always look at the plant— but it’s giving a new level of understanding of what the plant is going through. This is integral to a consultant’s work: a combination of looking at the plant and analyzing data from monitoring it.
