SHD olive crops

The SHD olive grove is a revolutionary new agronomic model driven by Agromillora for over 30 years in an effort to solve many of the problems that faced by growers in traditional crops. Our system translates into much more profitable and efficient crops for our customers.

Meet the projects of super high density crops.


Características del sistema en olivo superintensivo

  • SHD plantation with Smarttree® plants.
  • Clonal propagation of dwarf varieties.
  • Varieties featuring fast entry into production.
  • Planting patterns (3-4 x 1-1.5 m). High planting density (+1,600 plants/ha).

Advantages

  • Increased productivity per area unit.
  • Total mechanisation from the moment of planting, with the aim of reducing costs and work.
  • Early entry into production, with a faster amortisation of the investment.
  • Less cultivation work and labour, which is increasingly scarce and costly.
  • Fully mechanised harvest: Increase in speed and efficiency using over-the-row machines.
  • High quality of oil obtained, 100% extra virgin.


Olive tree varieties compatible with SHD cultivation.

Choosing the right variety is one of the core aspects to achieve the objectives of an SHD plantation.

We have six varieties for this system to suit different agro-climatic and crop conditions which likewise meet the stringent demands of the olive sector.

Arbequina AS-1

Overall evaluation.
Reference variety of the SHD system, easy central axis layout. Medium vigour, although the final size depends largely on climatic conditions and farming method. It is productive and constant, early entry into production. Ripening begins in early November in warm areas of the Northern Hemisphere.

Denominación y sinonímias

La arbequina recibe esta denominación por su zona de origen, probablemente cercana al pueblo leridano de Arbeca. Se encuentra también con las denominaciones Arbequí, Arbequín y Blancal. La Arbequina AS-1 es una selección de la variedad Arbequina muy productiva y totalmente adaptada al sistema superintensivo.

Área de cultivo

Es la variedad más importante de Cataluña, donde ocupa más de 55.000 hectáreas. También se ha difundido en el resto de España, sobretodo en Andalucía. Es la variedadad de referencia en las nuevas plantaciones superintensivas, por este motivo además de España se ha plantado en muchos otros países; Francia, USA, Chile, Portugal, Italia,Túnez, Marruecos, Australia y Argentina.

Overall oil profile.
Strong, green virgin oil featuring a good aromatic harmony and very bitter, spicy and astringent. Persistent.

Koroneiki i-38

Overall evaluation.
Variety suitable for SHD system, erect/open structure and medium/high vigour, preventing the central axis layout. It is very productive and early entry into production. It delivers a very high oil yield. Ripening is two weeks later than the Arbequina variety. Very low resistance to cold, so planting on raised plots with good sun exposure is advisable.

Main features of the Koroneiki i-38 clone.
Tree:
Erect/open structure
Medium/high vigour
Fruit:
Olive weight (g) 1.07
Pulp/bone ratio 2.70
Oil yield (% measured on dry matter) 51.10

Overall oil profile.
Green virgin oil, very complex and highly stable. Persistent and high in astringency. Characteristic green colour.

Sikitita

Overall evaluation.
Very productive variety and optimal for super high density system plantations. Weeping structure and dwarf. Early entry into production. Ripens one week before the Arbequina variety. Good oil yield and extractability performance.

Main features of the Koroneiki i-38 clone.
Tree:
Weeping structure
Low vigour
Fruit:
Olive weight (g) 2.70
Pulp/bone ratio 5.50
Oil yield (% measured on dry matter) 49.65

Overall oil profile.
Sweet virgin oil featuring an intense fruity flavour and low levels of bitterness and spiciness. It is a soft, smooth and balanced oil on the palate.

SHD olive grove features

Planting pattern

The most widespread planting patterns currently vary between 3-4 m row distance and 1-1.5 m between trees. This implies planting densities of above 1,600 plants/ha. Choosing a suitable plantation pattern suitable for the agro-climatic features of the area in question and the variety of choice is paramount to the success of the plantation.

Production.

Entry into production is very fast. In the third year of planting yield is 3-4 t/ha. The results obtained in these years of experience in different olive-growing areas result in sustained yield values of between 8-12 t/ha. In warm-area plantations, and under appropriate crop management, yields can reach up to 16 t/ha.

Cost effectiveness.

Choosing a suitable plantation pattern suitable for the agro-climatic features of the area in question and the variety of choice is paramount to the success of the plantation.

Crop quality.

The mechanized harvesting that takes place in the SHD olive grove ensures that fruits can be collected in proper ripening conditions with minimal damage and allows a quick delivery to the mill for grinding. These factors are important when in order obtain extra virgin olive oil (100% extra virgin olive oil) boasting outstanding organoleptic qualities.


Smarttree®

Our 30 years of experience working with SHD olive groves have helped us improve how these plantations are managed and implement their cropping system.

The most significant improvement has come with the revolutionary Smarttree® plant system, designed for the SHD system.

Smarttree® plants are the perfect solution for new super high density plantations, since they allow fully mechanising all growing tasks from planting onwards. This in turn reduces costs, ensures a continuous hedge in the shortest possible time, increases oil production per hectare and improves the efficiency and profitability of a SHD olive grove.

Thanks to this format, planting olive grove plantations can take place in any season, according to the specific climate conditions of the project, avoiding winter in frost-risk zones and the summer in very hot zones.

Smarttree® Features

  • Total mechanisation from the moment of planting, unlike the central axis layout, which implies significant labour savings.
  • Maximum genetic and health quality.
  • Shorter nursery production time.
  • Plant, 60 cm high with numerous branches from 50 cm, with stake.
  • Strong root system and developed in inert substrate.
  • Plant provided with a plastic protector to protect it from the use of herbicides at the moment of planting and avoiding suckers.
  • Ease of transportation and planting.
  • Efficiency of the production process
  • Mechanized planting. Planting in SHD systems is a highly efficient and highly technical process. Prior to planting, the soil is prepared (with a slope not exceeding 20%), varieties are chosen, and the plantation pattern/orientation of rows designed. Currently, the Smarttree® [link to Smarttree®] plants featuring a plastic protector offer plantation yields that exceed 6,000 plants/day.
  • Mechanized pruning. Pruning is certainly one of the key tasks in olive groves and other fruit trees. The SHD system allows mechanising pruning, significantly reducing operating costs. By using our revolutionary Smarttree® [link to Smarttree®] plant, pruning can be machined completely, thereby considerably boosting crop profitability. The objective of pruning is to keep the olive tree productive, ensuring a correct wood-leaf ratio and keeping it at the right size for the harvesting machine.
  • Mechanised harvesting. 100% mechanised harvesting. The same over-the-row machines used for harvesting grapes are employed. This system ensures that 98% of fruits are harvested resulting in minimal damage to both the olive and the tree. Yields may reach 1.5-2 hours/ha and harvesting costs range between 0.03-0.06 €/kg. This type of harvesting allows harvesting olives in a proper state of ripening and rapid delivery of the fruits to the mill for grinding, decreasing potential deterioration and possible undesirable flavours in the oil.
  • Hedge formation. The traditional super high density system, featuring the central axis layout, has become a thing of the past, superseded by Agromillora’s new Smarttree® [link a Smarttree®] free plant formation system. The new system allows full mechanisation of the work related to planting and hedge formation and pruning, resulting in a major cost reduction.

Advantages of Smarttree® layout

  • Lower initial investment, since no poles or wires are required.
  • Decreased labour necessary during formation, since there is no tying involved.
  • Earlier entry into production by hectare: Only pinching occurs. Branches are never cut from Smarttree® plants, which exhibit greater development from the very beginning in the nursery.
  • Less relevance of attacks and insects that can damage the apical bud.
