Il Fiorello is working hard to be sustainable. We believe that good stewardship of our land and our trees is very important. Although we have just submitted paperwork for the formal organic license, we have been growing organically and sustainably for the past four years. Our Mill has been certified to mill organic olives for over 5 years. In our tours we always discuss how important it is to be good to the land and then reap the benefits in great fruit and healthy trees. We also discuss how we grow and care for the trees. Biodiversity on our property gives us a balance. Biodiversity is critical in a balanced farm and we grow olives, citrus, tend an organic culinary garden, figs, lavender, and plant flowers for the bees. All these plants encourage wildlife.
So what makes us say we are sustainable? First, sustainable agriculture is defined as environmental health, economic profitability, and social and economic equity. These are also the goals of Slow Food International: Good, Clean and Fair. The UC Sustainable Agriculture Research and Education Program at UC Davis has an excellent position statement on the concept of sustainable agriculture.
Let me take you on a tour of our beliefs.
Last year we made a significant commitment to solar energy production. Our home, the Visitor Center, and our milling barn all are solar supported. We are thankful to be able to use this fabulous source of energy. The solar savings are significant. Watching the Visitor Center solar counter run gives all of us great satisfaction. Our Milling Barn is also very well insulated to protect the oils and the machines. Our eight stainless steel oil storage tanks are well insulated and cooled.
Water management in this drought is so extremely important. We use only drip irrigation, from April to October, then we pray for rain. We have an onsite monitoring system that measures depth of soil moisture content at one, two, three, and four feet. This corresponds to olive root depth. We also take into account temperature, evapotranspiration, and wind effect. Olives close the pores of their leaves in high temperatures and hot winds, a lifesaving characteristic. They are drought tolerant but our little trees need some help. During milling water conservation is important and our centrifuges operate with little water in a very efficient manner. We actually may use more water for cleaning the mill than in the process of making oil.
To feed the trees we use a technique called fertigation, irrigate and feed at the same time. Dual purpose and efficient. We use an organic kelp fertilizer and do tissue, leaf, and soil samples to guide our applications.
Our commercial water treatment plant converts available waste water from milling and from the Visitors Center to usable water that is shifted to the groves.
At Il Fiorello we actively practice sustainable agriculture. Stewardship of our land and trees is very important to us and will remain a central theme of our business.
