The basalt flour amendment improves the size and especially the flavor of the olives.

Agricultural amendments are a common practice in agriculture to improve crop quality and productivity. One of these amendments is basalt flour, which is used especially in olive crops.

Basalt flour is a type of volcanic rock that is pulverized and added to soil as a mineral amendment. This rock contains a large amount of nutrients important for plant growth, such as calcium, magnesium and iron. In addition, it also contains trace elements and minerals such as silicon, boron, manganese and cobalt that are essential for plant health.

Regarding the benefits that basalt flour can bring to the flavor of olive fruit, several studies suggest that olive trees that have been treated with basalt flour have a higher concentration of aromatic compounds and polyphenols in the fruit, which contributes to a more intense and complex flavor. These compounds can also improve the fruit's resistance to diseases and pests, which in turn can improve the quality and quantity of the harvest.

Additionally, basalt flour can also help improve soil structure, increasing water holding capacity and improving aeration, which can help olive tree roots grow stronger and deeper. All of this can contribute to greater resistance of olive trees to environmental stress and greater productivity in general.

In summary, basalt flour is a popular agricultural amendment for olive crops due to its high nutrient content and its ability to improve soil quality and crop resistance to diseases and pests. In addition, it can contribute to a more intense and complex flavor in the olive fruit.
