Last updated:December 23, 2021 Welcome to Earthworm Central, our new site for the Earthworm software and community to organize and contribute to a great open source tool in seismology! Please contribute your time to helping maintain and move forward this great resource. Release Status On August 20, 2019 version 7.10 was released. This new version has vastly improved stability and improvements to Earthworm including 64 bit compilation for all modules. We still support 4 flavors of Operating System: Windows, Mac OS X, Linux, and Solaris (however we are not compiling on SPARC for solaris; if you need this operating system look at Earthworm 7.8.) Note: You can always get the most current version from git: git clone -software/earthworm.git
- Static Web Documentation (v7.10)
- Google Group _forum?hl=en
- Downloads (Source, Binaries, Fixes, Addons, etc)
- Developer Community Gitlab Page - where to register bugs/issues/requests, get GIT workflow information etc.
- SeisNetWatch - the definitive tool that many EW users use to monitor seismic networks

Earthworms are vital to soil health and to plants growing in it because they transport nutrients and minerals from below to the surface via their waste. An earthworm can eat up to a third of its body weight in a day.
This Test Guideline is designed to be used for assessing the effects of chemicals in soil on the reproductive output (and other sub-lethal end points) of the earthworm species Eisenia fetida or Eisenia andrei.
Charles Darwin died 130 years ago today, leaving an intellectual legacy which has profoundly influenced the general course of Western thought. He is best known for his work On the Origin of Species(1859) and The Descent of Man (1871), both of which introduced radical new ideas for the time concerning the origins of humans and all life. Darwin's last work, however, devoted itself entirely to a more down-to-earth species: the lowly earthworm.
With the help of his children, with whom he set out early each morning (and often on rainy nights) while the ground was still cool and moist, Darwin observed and recorded the habits of the earthworm and its effect on soil formation. Darwin learned that worms literally move the earth in the process of their meanderings. Their passage through the earth aerates the soil and the natural chemistry of their guts renders soil and plant matter into fertile pellets. As a by-product of their movements, worms deposit new soil on the surface, causing whatever was on top to slowly submerge. Thus, whole monuments may be buried over a period of decades. It is estimated that for a single acre of cultivated land, earthworms move 8 tons of earth in a year, enough to produce a new layer of earth 2 inches thick, rich in nitrogen, phosphorous and calcium.
The carbon that is consumed, processed and then excreted by earthworms is a key building block in a well-structured soil, says Amanda Ashworth, soil scientist at the ARS Poultry Production and Products Safety Research Unit in Fayetteville, Arkansas.
Ashworth and her colleagues at the ARS Dale Bumpers Small Farms Research Center in Booneville, Arkansas, and at the University of Tennessee, inventoried earthworm populations in soils where no-till cropping systems and cover crops and poultry litter had been used for 12 years. They found that earthworm populations were twice as abundant in soils where corn and soybean are grown. Also, earthworm populations were more than twice as large in field tests that used poultry litter.
The earthworm or the night crawler, was first native to Europe but is now all over North America and Western Asia in large quantities. Earthworms are found everywhere, except in freezing regions and deserts. There are about 6,000 species all over the globe.
Earthworm is the common name for the largest members of Oligochaeta (which is either a class or subclass depending on the author) in the phylum Annelida. In classical systems they were placed in the order Opisthopora, on the basis of the male pores opening posterior to the female pores, even though the internal male segments are anterior to the female. Theoretical cladistic studies have placed them instead in the suborder Lumbricina of the order Haplotaxida, but this may again soon change. Folk names for the earthworm include "dew-worm", "Rainworm", "night crawler" and "angleworm" (due to its use as fishing bait).
Although earthworms are beneficial in most agricultural systems, they can wreak havoc on meticulously managed, closely-mowed sports turf. Large numbers of earthworm castings deposited on the surface can render golf putting greens and croquet courts virtually unplayable, and excessive earthworm burrowing activity can cause root desiccation and turf thinning on athletic fields. The castings interfere with turf maintenance by dulling mower blades, preventing a clean cut. When compacted by foot traffic, carts, or mowing equipment, castings can create silver-dollar sized mud spots that can critically damage the turf underneath.
Potter said the Chinese turf managers apply the substance to the turf and then water it into the soil. In response, the earthworms come out of the ground and then turf managers rake them or hose them off of the playing surface, thus eliminating the casting problem.
Potter said earthworm management is a problem on golf courses worldwide. Currently no pesticides are approved to manage the problem in the United States. For the most part, turf managers are currently dealing with it by brushing the castings off the course with brooms or similar tools, which is labor intensive and not really a long-term solution. But, there are no published studies on this management approach.
In all, more than 7,000 earthworm species exist in moist soils across all continents, except for Antarctica. The invertebrates are important decomposers of organic matter and help improve soil health by promoting aeration and recycling nutrients.
Bruce Snyder, instructor in K-State's Division of Biology, has received the first set of earthworms back from Kansas middle- and high-school classrooms as part of the Earthworms Across Kansas: A Citizen Science Approach to an Invasive Species Survey, funded by a grant from the K-State Center for Engagement and Community Development.
Currently more than 220 free earthworm roundup kits, containing four vials of preserving fluid, collection labels, a pencil, instructions and a return shipping label, have been requested and shipped out to teachers across the state. Snyder, however, still has resources to produce at least 200 more free kits and is continuing to accept requests from interested teachers and home-school instructors.
The project is designed to meet state academic science benchmarks while giving teachers an opportunity to take their classroom outdoors. In return Snyder will receive valuable data on the distribution of invasive earthworm species in Kansas.
In addition to requests for collection kits, the website has distribution maps of the previously known earthworm species and earthworms that have been returned. The website continues to be updated with lesson plans and other resources.
Earth Science Earthworm Castings, 4 lb, are made with 100% earthworm manure. We never cheapen our product with lower cost fillers of any kind. Professional growers have relied on earthworm castings for years to improve the soil. Regular use of earthworm castings increases the water and nutrient holding capacity of soils and encourages plant growth. Earth Science Earthworm Castings are carefully harvested and packaged to provide the best results. They are an excellent supplement for all types of plants, whether in the ground or in containers. This product provides a good source of Nitrogen. Nitrogen encourages plant growth and helps provide foliage with its green coloring. Healthy soil contains and requires this nutrient to thrive.
