Acidic soil, which is soil with a pH lower than seven, can be a problem if you intend to grow certain plants, such as vegetables, most annuals, and lawn grassAll of these types of plants perform poorly in acidic soil because soil acidity prevents them from taking up nutrients from the soil
Will soil washing work at every site? Soil washing works best when the soil does not contain a large amount of silt or clay In some cases, soil washing is best applied in combination with other treatment technologies, rather than as a technology by itself Removal of contaminants can often be improved during the soil washing process by adding .
