On the afternoon of October 6, the Department of Agriculture and Rural Development of Ham Yen district (Tuyen Quang) presided over and coordinated with specialized units of the district to inspect and initially determine the cause of the phenomenon of many worms crawling to the ground in Trung Thanh 1 village, Thanh Long commune.
Through inspection and assessment, the entire area of the melon field had worms crawling on the surface of about 15 sao of 6 households. When digging the soil to check (the surrounding field edge area), the worms were found to be very healthy, not dead, and had a high density of worms. The soil in the field was loose and rich in humus, very favorable for worms to grow and develop.
Initially, the experts determined that the phenomenon of worms crawling up to the ground originated from the following reasons: People use fertilizer (chicken manure) to fertilize melon plants, so during the decomposition process, it will generate heat, making the soil hot and lacking air in the soil. Along with that, households use nylon to cover the beds of melon plants with high density, which also reduces the air in the soil, causing worms to crawl up to the ground to breathe.
In addition, the weather has changed recently, during the day it is sunny and the humidity is low, combined with fertilization, the air in the soil has decreased, causing worms to come to the surface in large numbers. When the weather is sunny and hot, the worms go back to the ground around the edge of the field.
The district's professional agency also confirmed that worms are very good for the soil. The worms crawling to the surface of the soil is a normal phenomenon that does not affect production.
District authorities also came to inspect the landslide that affected the house of Mr. Dang Van Dap, Trung Thanh village 1, Thanh Long commune, about 100 meters from the melon field where worms crawled up to the surface. Through assessment, this landslide occurred on September 12, far from the melon field, so it had nothing to do with the phenomenon of worms crawling up to the surface.
The local government has also directed the officials of Trung Thanh 1 village to continue to propagate so that people do not panic, avoid superstitious activities that affect security and order, and take measures to protect against bad guys from stealing worms and destroying the soil environment in this area. At the same time, continue to closely monitor this phenomenon, if there are any abnormalities, it is necessary to notify early to have appropriate solutions, to avoid public panic.
