Prevention & Treatment: Do not plant beans in low-lying, poorly drained areas. Plant beans on raised beds. Plant after the soil has warmed to 69 Â°F at a 4-inch depth. Reduce disease buildup in the soil by rotating locations in the garden where you plant bean or pea with other vegetables.
These collapses can be small, or, as this picture shows, or they can be huge and can occur where a house or road is on top. The most damage from sinkholes tends to occur in Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania. The picture to the left shows a sinkhole that quickly opened up in Florida, apparently eating a swimming pool, some roadway, and buildings.
The Science of Sinkholes. Sinkholes are common where the rock below the land surface is limestone, carbonate rock, salt beds, or rocks that can naturally be dissolved by groundwater circulating through them. As the rock dissolves, spaces and caverns develop underground.
