Sulfur is an essential macronutrient needed in plant growth. Volcanoes tend to release small amounts of sulfur into the air. Probably: "Particles released by volcanoes contain sulfur, which is good for soil." or "Particles released in the air by volcanoes fall to the ground and enrich the soil." It is most likely the latter one because this sulfur is released in a gas, therefore it would fall to the ground and enrich the soil.
