In order to understand more about the changes in vegetable greenhouse soils in coastal areas of China, 150 soil samples were collected in vegetable greenhouses aged from 1a to 17a from Haiyang County, Shandong Province. Results showed soil bulk density decreased first but increased slightly after 11a. Soil pH decreased by 25.0% over 17a. Organic carbon content increased by 86.8% in the first 11a and then dropped by 69.7% in the last 6a. Total nitrogen content increased by 1.41 times over the first 8a and then declined by 52.3% in the last 9a. AHN content increased by 79.5% in the first 8a and declined by 41.8% in the last 9a. AP content increased by 38.6 times in the first 8a and declined by 68.9% in the last 9a. AK content increased by 4.4 times in the first 11a and declined by 77.7% in the last 6a.
