Nourishing the Soil to Nourish the Vine: Regenerative Viticulture Meets Precision Technology in Puglia

Location: Noicattaro (BA), Puglia · Crop: Autumn Crisp table grapes · Grower: Rocco Decaro

There's a simple but radical principle guiding Rocco Decaro's work in his Autumn Crisp vineyard in Noicattaro, at the heart of Puglia's table-grape country: nourish the soil to nourish the vine, not the other way around.

It's an approach that turns the logic of conventional viticulture on its head — a logic usually focused on acting directly on the plant through synthetic chemistry. Here the road is a different one: regenerative, organic agriculture, where the soil isn't a mere physical support but a living ecosystem to rebuild and safeguard.

A vineyard that works with microbiology, not against it

Choosing to give up synthetic chemistry and invasive tillage wasn't only an agronomic decision — it was a genuine vision. The work in the field is built on:

• Consortia of beneficial microorganisms (EM), to reactivate the soil's biological life
• Zeolites, to improve soil structure and its capacity to hold water and nutrients
• Organic matter, to rebuild natural fertility over time

The aim is to recreate a system in balance, where the plant finds everything it needs in the soil, without external forcing.

Precision technology in the service of the land

A regenerative approach doesn't mean giving up scientific tools: it means using them to listen to the land more closely. That's where SoilSense sensors come in — installed 20 and 40 cm deep in the vineyard since last year, to monitor the soil exactly where most of the root system sits.

"SoilSense sensors are essential for constantly monitoring soil moisture and how the soil responds, letting me manage irrigation scientifically — without wasting water and in complete harmony with the system I've built."

The chart below, taken from the SoilSense platform, shows this principle in action: plant-available water (top) rises sharply with each irrigation and then draws down gradually, while the volumetric water content of the soil (bottom) follows the same rhythm at two depths (20 and 40 cm). The green band marks the safe moisture range: every irrigation is calibrated to bring the soil back into that band, with nothing wasted.

Soil temperature, tracked at the same two depths, tells the same story of stability: smaller, more gradual swings than the air temperature above, the signature of a living, well-structured soil that shields the roots from climatic extremes.

Alongside the soil, the platform also keeps an eye on the microclimate above the canopy: a datalogger in the vineyard continuously records air temperature — a complementary reading that helps interpret the plant's heat stress and relate the weather to how the soil responds.

Continuous soil-moisture monitoring makes it possible to:

• Irrigate only when it's genuinely needed, avoiding wasted water
• Understand how the soil — brought to life by the biological work — responds over time
• Make decisions based on hard data, not estimates or habit

In a regenerative system, where soil health is the heart of everything, having objective, continuous feedback on the soil's water response becomes a valuable tool for validating — and refining — agronomic choices.

The result: a healthy, loose, resilient bunch

The alignment between agronomic vision and precision water management translates into a tangible result, visible right in the bunch: a healthy, loose, resilient structure — the mark of well-managed water and nutrition.

But the goal, as Rocco Decaro is quick to point out, goes beyond simply producing fruit:

"Our goal isn't simply to produce grapes, but to offer the consumer an authentic, healthy fruit — the child of a living soil that is respected and cared for."

Living soil, living data

This story captures what it really means to bring regenerative and precision agriculture together: two approaches that might look distant at first glance, but that in fact reinforce one another. Work on the soil's microbiology makes the ground more receptive, better able to hold water and nutrients; constant monitoring makes it possible to measure — and therefore value — that work, guiding every irrigation decision without waste.

The result is a fruit that carries with it the story of a land that is cared for, observed, and respected, day after day.
