Read the passage and answer the question.

Volcanic soils, formed from weathered ash and lava, are prized by farmers for their exceptional fertility, a quality stemming from their high mineral content, particularly potassium, phosphorus, and trace elements essential for plant growth. The porous structure of these soils also allows excellent drainage while retaining enough moisture for root systems, a balance that reduces both flooding and drought stress compared to denser soil types. However, this fertility is not immediate: freshly deposited ash can initially be inhospitable to crops due to high acidity and the presence of soluble toxic compounds, and it may take years or decades of weathering before the soil reaches optimal productivity. Farming communities near active volcanoes therefore accept periodic destructive eruptions as a trade-off for long-term soil renewal, a pattern observed in regions from Indonesia to Central America.

According to the passage, why might freshly deposited volcanic ash be unsuitable for immediate farming?
