Realizing 10% More Fruit Weight Throughout The Season with Source Track

• It is challenging to keep red pepper fruit weight consistent throughout the season, particularly with the Alzamora pepper variety. If plants are stretched out too much early on in the season, this cultivar will not perform well in terms of fruit weight towards the end of the season.

• C. Zwinkels had issues with a new aphid last year which resulted in ending cultivation early and cost them 2 kg/m2 (on top of €0.50/m2 extra labor costs.)

• Climate computers show a large amount of data, which can make it challenging to identify the root cause of problems. Especially for new, less experienced, growers.  

Zwinkels engaged with Source.ag in the summer of 2022 and deployed the Source Track dashboard to provide key data for the new cultivation, and Source App to measure plants with granularity and consistency.

Source Track is a hardware-agnostic platform that tracks, compares and improves cultivations. Source Track helps growers manage more hectares more effectively. It provides growers with one platform to track all of the data surrounding a cultivation, generating and sharing insights across multiple facilities so that growers can get an overall view across all operations.

With Source Track, C. Zwinkels can get a single overview of the state of its most important KPIs across all three of its greenhouses. Using Source Track, C. Zwinkels began to track:

- Ratio of irrigation to light
- Plant load
- Drain
- Dry down at first irrigation cycle
- Dry down at sunset
- Total dry down

By simulating plant biology and helping to optimize photosynthesis, Source Track indicates whether C. Zwinkels’ KPIs are on or off track, helping Arus to make the best decisions based on all the right data. Source Track provides a simple and intuitive dashboard to show all KPIs that matter to its optimal cultivation. Data-driven insight can be accessed anywhere, at any time, meaning the grower has a constant overview of operations.

Source Track also provides C. Zwinkels with the tools to work towards a more strategically optimized crop plan, allowing it to compare the realized results with the original growing plan. With more careful planning for the season, the grower has been able to determine when it should speed things up, and when it shouldn’t. 

Keeping a clear overview of three greenhouses used to be challenging for the grower. With Source, C. Zwinkels can get a single overview of the state of its most important KPIs across all three greenhouses. Using only the climate computer, the grower could not see the connections and correlation between the graphs and the KPIs, but in Source, this is easily demonstrated. 

In addition to this, the grower has also started looking at new and previously unknown KPIs in Source, which is delivering more in-depth insight into the new cultivation. Arus explains that Source helps him to monitor historical timelines and trends, whereas previously, the climate computer only showed the current state of any given KPI: 

“In the climate computer, I can't see the connections between graphs and KPIs, but in Source I can. This gives me a clearer view of the current status of my cultivation and of course, any adjustments or decisions I need to make. With Source, I can also look further ahead, forecasting using real plant data, which is much more accurate. I can see how many set fruits I can expect just by looking at the number of flowers that I register in the app.” 

Since using Source, C. Zwinkels has seen considerable improvement in revenue, both in spring and autumn, largely due to being able to produce bigger, better peppers that are in demand. 

Before implementing the technology, peppers would regularly not reach target weights by the end of the growing season. After applying Source, C. Zwinkels is now able to produce peppers with 10% more weight throughout the whole season. This is down to better-growing decisions made throughout the season, which has resulted in getting more peppers from the main branch, which are heavier and grow quicker. 

C.Zwinkels is now able to sell 80-90% of peppers even in the last three weeks of the season, in comparison to 50% during this end-of-season period in previous years. 

“One wrong decision can make or break a season: when cultivations get off course at the beginning of a season, it is difficult to be profitable. With Source, I’m able to look more into the future. Instead of spending countless hours on climate computers, Source tells me the status of my cultivation, pointing out deviations that I can act on immediately to keep my cultivation on course." - Arus Biersteker - General Manager and Head Grower C. Zwinkels

Finally, working with Source inspired C. Zwinkels to track new KPIs that they hadn't thought to track before. These KPIs deliver more in-depth insight into the new cultivation.
