What is dry-farmed almond growing and why does it work in Murcia?
A dry-farmed almond grove is an orchard grown without regular irrigation, relying almost entirely on rainfall stored in the soil. On the Yecla highland plateau in the north of Spain's Murcia region, this is the traditional way to grow almonds: trees set at wide spacing, deep roots, and varieties bred for dry summers and cold winters. The estate Altiplano Almond Grove, covering 38 hectares of that plateau, is a clear example of how rainfed almonds are farmed today.
What exactly is a dry-farmed almond grove?
A dry-farmed almond grove is a planting that depends almost completely on rain. Instead of supplying water through drip lines across the whole season, the grower manages soil moisture: trees are spaced farther apart so each one has a larger water reserve, cover crops slow evaporation, and the soil is worked as little as possible so that reserve stays intact.
The core principles of this model are:
- Wide spacing: fewer trees per hectare, but each one draws water from more soil.
- Resilient varieties: almonds that flower late and tolerate drought well.
- Minimal tillage: the ground is disturbed little to preserve moisture and soil structure.
- Cover crops: grass between rows that guards against erosion and water loss.
At Altiplano Almond Grove most of the land is farmed this way, in pure dry farming. Only one strip, the most exposed to sun and wind, has supplementary drip irrigation to secure the harvest in the driest years.
Why are late-flowering almonds grown in Murcia?
The biggest threat to almonds in inland Murcia is not the summer heat but spring frost. Almond trees bloom very early, sometimes in February, and a single night of frost on the open blossom can wipe out the whole crop. The fix is to plant varieties that flower later, once the frost risk has dropped.
That is why, in 2015, the third generation of the Ortuño family brought in late-flowering varieties such as Soleta and Belona, able to delay their bloom enough to dodge frost on the plateau. It is a common technical move in modern almond growing across southeast Spain: shift the flowering calendar to cut climate risk without giving up quality.
Which almond varieties grow best on the Yecla plateau?
The Yecla plateau combines altitude, limestone soils, and cool nights, an environment that suits several varieties at once. At Altiplano Almond Grove five of them grow side by side:
- Marcona: the sweet, rounded almond prized for confectionery and turrón, a Mediterranean classic.
- Soleta: a late-flowering, productive variety well suited to dry farming.
- Belona: also late-flowering, with a good-sized kernel and frost resistance.
- Guara: self-fertile and early-harvesting, widely planted for its reliability.
- Largueta: a long, slender almond traditional to Spain's Levante coast.
This mix is no accident. Combining early and late varieties spreads frost risk across the spring and staggers the harvest, so the seasonal crews do not have to pick everything at once.
How does dry-farmed almond yield compare to irrigated?
As a rule, an irrigated almond tree produces more kilos per hectare than a rainfed one, because steady water supports a heavier crop load. Even so, dry farming has advantages that explain why it remains the dominant system in areas like Yecla:
- Lower costs: with no irrigation water or pumping energy, per-hectare expenses are lower.
- Less water dependence: in a water-scarce region, not competing for irrigation is a strategic advantage.
- Quality and flavour: moderate water stress tends to concentrate the kernel, something the almond market values.
Dry farming yields swing more from one season to the next because it depends on rainfall, but in return it is more sustainable and cheaper to maintain. That is why estates like Altiplano Almond Grove rely on dry farming as the base and keep drip irrigation only for the most vulnerable strip.
A grove with history on the plateau
Altiplano Almond Grove did not start out as an almond farm. It began in 1978, when the Ortuño family converted part of an old vineyard to almonds to diversify after several poor grape harvests. In the 1990s they replanted the rows at wider spacing, designed for mechanised cultivation and to give each tree a larger soil-water reserve.
The technical leap came in 2015, with the arrival of late-flowering varieties and the supplementary irrigation strip. Today the estate is run by a family partner alongside two permanent workers and seasonal crews for harvest, and the crop is sold in bulk to a local mill and huller. It is the familiar path of many farms in the southeast: adapt to the climate, mechanise where it counts, and choose varieties that lower risk.
How does an almond grove fit into atseis?
On atseis, a real farm like Altiplano Almond Grove is divided into shares that let you connect to the estate and follow its activity across the seasons. The aim is to bring the countryside closer to anyone who wants to understand how a real crop works, with its rhythms of flowering, harvest, and sale to the mill.
Knowing the fundamentals of dry-farmed almonds (the late varieties, the moisture management, the harvest calendar) helps you read what happens in the grove season after season. Almond growing on the Yecla plateau is a patient crop, tied to the rain and to sound decisions about what to plant and when it blooms.
