The red soils found in the Yarkon River area are rich in iron oxides, lending them a distinctive reddish color. These soils are generally derived from the weathering of crystalline and metamorphic rocks in areas of high rainfall. They contain large amounts of clay and are typically acidic, which can sometimes lead to a lack of sufficient nutrients. Despite this, the red soil is fertile and ideal for citrus cultivation. However, in the winter, the area's rural roads can become impassable due to mud, making travel challenging. This characteristic red soil is partly due to iron oxide, which is transported to the region from Africa through the Nile and along the eastern Mediterranean coast.
