Guide for Organic Olive Oil Producers in Tunisia and Accuracy of Standards
What does organic olive oil mean?
Organic farming in Tunisia is not just the absence of medicine and chemicals in analyses, it is a complete production system that respects nature and ecological balance from the first day in the field until the day the oil is sold. This system strictly prohibits the use of synthetic chemical fertilizers and hormonal pesticides, and relies on protecting consumer health and soil, ensuring fairness in the exploitation of water and natural resources.
Tunisia today is considered one of the pioneers in the world in organic olive areas and export volume. To maintain this reputation, the state has set strict laws and specifications that every farmer must respect to obtain certification and classify their oil as premium organic. A basic rule to know is that organic oil requires complete and clear traceability, meaning the farmer must record every detail in the farm register, from the type of manure used to the date of harvesting and pressing.
First: Basic conditions on the farm (agricultural production stage)
* Transition period: To convert a regular farm to an organic one, you cannot sell its oil as organic from the first year. It must undergo a transition period lasting 3 full years for olives. During these years, the farm remains under surveillance to completely cleanse the soil and trees from old pesticide residues, and the product is sold under the name "oil in transition".
* Windbreaks and estate protection: The organic farm must be protected from pollution coming from neighbors using chemicals. The farmer must plant natural windbreaks (like prickly pear, cypress, or dense trees) or leave a sufficient safety belt so that the neighbor's pesticide spray does not reach the organic olive trees.
* Plant protection and disease control: Control here relies on natural prevention such as strengthening the tree with proper pruning, cleaning the land, and encouraging beneficial insects that eat harmful ones (like the olive fly). If necessary, the farmer only uses materials authorized in the specifications, such as copper solution or sulfur, and food and sexual traps, and any synthetic chemical pesticide is prohibited.
Second: Detailed technical part – Organic fertilization protocol and soil nutrition
Since chemical fertilizers (like ammonia, urea, and synthetic phosphate) are strictly prohibited, feeding the olive tree relies on organic matter and the natural soil cycle according to the following protocol:
* Use of fermented manure: Not just any manure is put into the ground. Fresh manure can bring diseases, fungi, parasitic weed seeds, and burn tree roots because it has a high ammonia percentage. The farmer must use animal manure (cows, sheep, or poultry) that has been fully fermented for at least 4 to 6 months with careful turning and moistening. The fermentation process raises the temperature to 60 degrees, killing germs and making nutrients (nitrogen, phosphorus, potassium) easy and stable for absorption by the tree's roots.
* Green manure: This is an excellent technique based on planting legumes (like fava beans, clover, or peas) between olive rows in autumn (October and November). Legumes have a unique property of fixing nitrogen from the air into the soil through their roots. At flowering time (February and March), the farmer plows the land and turns these plants into the soil, which provides very rich organic matter that improves soil fertility and structure and increases its moisture-holding capacity.
* Valorization of Margine (olive mill wastewater): The farmer can spray margine on the farm as an excellent natural fertilizer rich in potassium and organic matter, but under very strict conditions: the quantity must not exceed 50 cubic meters per hectare per year, it must be sprayed homogeneously and at least 1 meter away from the tree trunk, it is forbidden to spray it on lands with a close water table or steep slopes, and it must be raw margine not mixed with chemicals.
* Valorization of Pomace: Pomace is mixed with animal manure during the fermentation process to produce excellent compost rich in carbon, improving the soil's ability to retain water and feeding beneficial microorganisms in the ground.
* Use of natural extracts and seaweed: To improve leaf growth and excellent flowering, the producer can use a foliar spray with authorized seaweed extracts or natural amino acids, giving a strong boost to the tree at critical times (like fruit setting, during droughts, and lack of rain).
Third: Conversion standards inside the mill (pressing and packaging stage)
The accuracy of standards continues inside the mill so that organic oil does not mix with regular oil:
* Cleanliness of production lines: The mill must be fully washed and sanitized with approved cleaning materials before pressing organic olives. Many mills dedicate the first days of the week or the first hours of the day exclusively to organic oil.
* Cold pressing: The temperature of the olive paste and added water must not exceed 27 degrees Celsius to preserve benefits and volatile aromas.
* Storage tanks: The oil is stored in fully insulated food-grade stainless steel tanks clearly labeled "organic olive oil" with the batch number.
Fourth: Control and certification system (How to get Bio certification?)
Control in Tunisia is carried out by accredited international companies registered with the Ministry of Agriculture (like Ecocert, CCPB, etc.), and the system works according to the following stages:
* Membership and contract stage: The farmer submits a request to the control body with a complete disclosure of the farm's area, location, and history, starting the calculation of the legal 3-year transition period.
* Field inspection stage: The inspector comes to the farm (mandatory once a year, plus unannounced visits) to check the registers, warehouses, and land to ensure the farmer is applying the specifications literally.
* Laboratory analysis stage: Samples are taken from soil, leaves, and oil and sent to the lab to search for any pesticide trace and scientifically prove the product is 100% clean.
* Certification and logo stage: Issuance of the organic conformity certificate, renewed every year, which authorizes the printing of the commercial Bio logo and export abroad.
Fifth: Financial privileges and encouragements provided by the Tunisian State
To encourage organic farming, the Tunisian State has put in place a package of significant grants and financial privileges for farmers and cooperatives:
* Equipment and machinery grant at 70%: The farmer receives a grant covering up to 70% of the cost of machinery and equipment specific to organic production (like compost machines, mowing equipment, etc.) with a ceiling of 200,000 dinars. This rate is 50% for cooperatives and development groups.
* Coverage of control expenses at 50%: The State reimburses the farmer 50% of the expenses paid every year to control companies to obtain the certificate, to help small farmers and ease their periodic financial burden.
* Tax exemptions: Facilitations and exemptions from taxes upon importing some authorized organic materials, and preferential and fast customs paths when exporting oil.
Sixth: Regional structures that assist the farmer (Example: Sfax and the Center)
The Ministry of Agriculture has set up a special organic agriculture department in every regional commissariat. In the Regional Commissariat for Agricultural Development in Sfax (Airport Road km 5.5), for example, there is complete support divided into the following circles:
* Extension, Support, and Programming Circle: This circle handles continuous training, information days, and field schools to teach the farmer how to make compost and treat with authorized materials.
* Development, Research, Analysis, and Pattern Stabilization Circle: Goes to the field, monitors farmers during the transition period, conducts technical inspections, and coordinates laboratory analyses.
* Professional Structures Activation, Marketing, and Export Circle: Helps farmers and groups participate in major exhibitions (like SIAMAP and MedOleo) and facilitates their connection with exporting companies and global markets.
Conclusion and Recommendations
The organic olive oil project in Tunisia is highly successful with a great and very profitable future, as its prices in the world are constantly rising and consumers are looking for healthy products. The complete secret to success is the accuracy of standards and strict discipline; record everything in the registers, work on organic fertilization with scientific and fermented methods, and always stay close to agricultural extension cells to benefit from grants and technical expertise and ensure the highest quality for our Tunisian oils.
