Installation of weather stations:


During 2019, Agro San Antonio took an important step by acquiring DAVIS brand weather stations for its La Moyina and Larmahue fields. These systems have sensors to monitor temperature, evaporation, humidity, UV rays, rain, among others.

The information is incorporated into the global monitoring system of DAVIS worldwide. These data allow us to better manage decision making, achieving more efficient and effective agronomic management.

Mapping and numbering of all fields

During 2019 Agro San Antonio completed the mapping of each of the plants in all the orchards, thus allowing a detailed management of each tree.

In parallel, each row of the fields was marked with their number and also with the number of associated plants. In this way, an extremely practical and useful tool for data management and to act more efficiently and timely in the detection of irrigation problems, pests and diseases is incorporated through a very simple element.

Systematic Pest Monitoring:

Together with the specialized company Xilema, a biweekly pest monitoring program has been established in all orchards, which is made visible through physical reports and on a web platform.

This system is enabled in the La Moyina, San Antonio and Cara Cara fields.

Thanks to the monitoring and strict compliance with the procedures, we have complied with the pest protocols for export.

To this important systematic support are added the scheduled visits of Marcelo Somoza, a pest specialist, with whom the results of the survey carried out by the company providing the service are analyzed in detail, in addition to the steps to follow, if necessary.

The exporting company, our strategic partner.


In recent years Agro San Antonio has structured a strategic alliance with Agricom, a leading export company, responsible for bringing and presenting our fruit in international markets.

Given the above, we have strived to maintain a transparent, close and trustworthy relationship. This proximity has allowed us, since 2016, to have our graphic identity in export boxes destined for the United States.

For us this fact is of great value and confirms the reciprocal trust between both organizations. We want you to ask for our fruit by our name.

Our export rate has been increasing year by year thanks to the professional and continuous care of our company, coupled with the technical advice that companies such as Agricom have provided us.

In 2019, we reached a record export rate of 92%. This achievement fills us with pride and is the product of the love and commitment of the workers of Agro San Antonio, of our work methodology and of the support of our main strategic partners.

Plants have to be good and feel good.

Beyond profitability, which is important for any company, Agro San Antonio seeks that its orchards, in addition to having sustainable production, look and feel good throughout the year. To achieve the above, we care to deliver the best food and water to our plants.

This is how in 2018 we installed a modern automated fertigation center in the Campo de Larmahue. Thus, each tree receives the necessary nutrients in a controlled and efficient way.

On the other hand, for more than two decades we have been working with the Las Garzas laboratory to obtain the relevant foliar analyzes, which allow us to know both the availability of nutrients in the soil and the nutritional status of the plant, among other data.

With this information Agro San Antonio develops customized fertilization programs in each of its orchards.

We also worry, permanently, that our plantations are clean, without garbage or other elements foreign to agricultural production such as plastics, cigarette butts, bottles, etc.  

The Use of Round Point Scissors.


Since 2014, we have integrated a type of American scissors with a rounded tip into our harvest.

However, after an internal examination we came to the conclusion that this scissor had serious problems in the cutting of the fruit, (lost the edge quickly) and also its ergonometric produced injuries to the worker. For this reason, and concerned about the welfare of our workers, we chose the leading scissors in the world, both in terms of functional quality and comfort for the worker.

During the year 2017 we acquired stainless steel scissors from the Spanish brand Les Nuleres.

A total of 37 hectares will be planted by October 2018. The well that will irrigate these lands through a technical system has already been developed and the Huerto California nursery is working on the production of the plants. This plantation will be carried out in Campo LARMAHUE, located 7 km to the east of the Pichidegua area, in a sector characterized by its deep lands and generous climate for citrus.

Titration of Oranges


AGRO SAN ANTONIO during the months of April and May we begin with an exhaustive analysis of the internal quality of the oranges, in such a way to determine the optimum moment (Brix and Acidity) in which to start the harvest. This monitoring is done with Agricom.

In this year 2017 and as a result of a hot summer season, the fruit underwent changes in its internal quality faster than usual. As a result, we and Agricom have decided to organize and implement a titration laboratory in the AGRO SAN ANTONIO premises.

Japanese Company Agreement


During this past June, the Cooperation Agreement was signed between AGRO SAN ANTONIO SANTIAGO and AGRISUPPLY SpA, a subsidiary of a leading Japanese company in production and distribution of orange marmalade in Japan. In this first year, commercial trade exceeded 140,000 kilos of oranges of excellent quality, after that a process in Chile was sent to factories in Japan for the production of orange marmalade.

Agro San Antonio brand in the world markets


We are very glad since for the first time we have incorporated our brand “AGRO SAN ANTONIO” in the boxes used to export our oranges, we have also given visibility to Pichidegua as home to the best oranges in the world. All the work done in AGRO SAN ANTONIO makes us feel proud of this step, and simultaneously commits us to further develop with joy an excellent product for key global markets.

Over than 130.000 oranges boxes are taken our brand through out the world, and those customers are testing the best flavor and color of our land. Our commitment is to continue to improve in order to generate identity and confidence with our product.

Harvest 2016


As every year, in the month of June AGRO SAN ANTONIO had their harvest of Fukumoto oranges in the fields of La Moyina and San Antonio, in the sixth region of Chile. With the help of a develop harvesting plan and with the support of an excellent team of more than 300 people willing to collaborate with quality production, the feast of orange recollection was done. Despite the work pressure, we always remind our self’s that if we work with joy our oranges will be sweeter and richer.

Once again we reached high standers of quality, with an export rate that exceeded 89%, and a curve caliber accumulated of 83% of the fruit to with 72 caliber. This year all of our fruit that was exported was channeled thru AGRICOM, the main destination was USA.

The transportation of the fruit from the orchards to the Polpaico de Agricom Plant was taken care of by Empresa de Transportes de Don Joaquín Retamales. The harvest fest for AGRO SAN ANTONIO is the culmination of a process that seeks to export the best flavor and color in the world.



Without a doubt if a person visits the orchard of AGRO SAN ANOTONIO from march onward he will be very surprise. Why? Each of the orange plants has a very carful system of “shoring” on the branches that carry the fruit which are close to the soil or uncoupling danger. It should be between 8 or 10 struts per tree. Each shoring is made with bamboo and must be prepare with wire in order to give the shape to provide the support and not damage the structure of the tree. There are almost 400.000 shoring that must be done each year. It has already generated a great experience.

Why is this done?

  • •Our trees are very generous in their production. They even go beyond what their structure allows them, considering also that pruning is done at skirts. We must answer with reciprocity to this generosity. This is why the shoring is done tree by tree, this way to ease the burden and also protect the fruit so it wont be close to the ground.
    • It is almost as an artisan work, and from what we have seen, practically unique in its magnitude and depth.
    • This practice allows us to maintain our trees healthy and not stress.
    • This practice allows us to recover values kilos of fruit per tree.
