Robotic Mowers & Fertilization | Why CRF Is the Perfect Match

A robotic mower only performs as well as the growth it is asked to manage. Feed the turf with a fast-release fertilizer and you get a growth flush the machine cannot keep up with. Feed it with a controlled-release fertilizer and growth stays steady, day after day, exactly the pattern a robotic mower is built for.

That is the first reason Granucote 23-5-12 +2MgO +CaO +TE and robotic mowing fit together so well. The second reason is just as important: you apply it once, and for the next six months you do not have to think about it again.

No growth peaks, by design

Every granule of Granucote is enclosed in a polymer coating. Nutrients are released gradually through that coating, driven by soil temperature, over a period of six months. There is no initial surge and no sharp drop-off at the end. The turf receives a continuous, predictable supply of nutrition.

Compare that to a fast-release fertilizer, which delivers the bulk of its nitrogen within days of application. The turf responds with a flush of growth, and the consequences show up immediately on a robotically mown surface:

• Longer grass between passes, undermining the even surface the mower was bought for
• More clippings on the surface, which can smother the sward and increase disease pressure
• Longer running times and more wear on blades, motors and batteries
• A dip after the flush, as the nutrient supply runs out

A robotic mower has a fixed cutting capacity per day. As long as daily growth stays within that capacity, the result is a beautifully dense, even sward. Controlled release is what keeps growth inside that window.

One application, six months of nutrition

The second advantage is simply convenience. One Granucote application in spring covers the entire main growing season. No repeat rounds, no split applications, no monitoring for the moment the previous feed runs out.

For a turf professional managing multiple sites, that is a fundamentally different way of working. Fertilization stops being a recurring task on the schedule and becomes a single planned action at the start of the season.

The strength of our partnership with Vitaro

This is exactly where the collaboration between Mivena and Vitaro comes in.

Vitaro supplies robotic mowers and handles both installation and maintenance. Their service model follows the season. In autumn, when the grass stops growing, they collect the machines and carry out the full service: new blades, checks, everything the mower needs for the next season. In spring they return to the customer, place the mower back on the lawn and apply Granucote at the same time.

The customer is left with one visit in spring and one in autumn. In between, the mower keeps the surface even and Granucote keeps the nutrition constant. Complete peace of mind, from one moment of contact.

A six-month controlled-release fertilizer fits that model perfectly. A programme requiring repeat applications simply would not: it would mean extra visits, extra logistics and extra cost, and it would undermine the very thing that makes the service attractive.

Complete nutrition, not just NPK

A frequently cut sward with a high tiller count has a continuous demand for a broad nutrient package, not nitrogen alone. That is why the full formulation matters.

Granucote 23-5-12 +2MgO +CaO +TE provides a nitrogen-led feed with sufficient phosphorus and a solid potassium level for stress and wear tolerance. Magnesium supports chlorophyll formation and therefore colour. Calcium strengthens cell walls, which supports wear tolerance on high-traffic surfaces. The trace element package covers iron, manganese, zinc, boron and the other micronutrients the plant needs in small quantities but cannot do without.

Because release is governed by the coating rather than by rainfall or irrigation, that complete nutrition stays available across the full six months.

Why robotic mowing produces a denser turf

It is worth noting what the mower itself contributes. Where conventional mowing removes a large amount of leaf material two or three times a week, a robotic mower removes a very small amount every day. The plant responds by tillering: producing more side shoots instead of upward growth. More tillers means more plants per square metre, and therefore a denser, more even and more wear-tolerant surface.

Combine that with a nutrient supply that never spikes, and the turf can maintain that density throughout the season.

In short

Robotic mowers need steady growth to deliver their promise. Granucote 23-5-12 +2MgO +CaO +TE provides exactly that: a gradual, complete and predictable supply of nutrition for six months, in a single application.

Together with Vitaro, we turn that into a complete service. They place and maintain the machine, we make sure the grass grows in a way the machine can handle.
