The USDA Pomological Watercolor Collection is one of the most unique collections in the Rare and Special Collections of the National Agricultural Library (NAL). As a historic botanical resource, it documents new fruit and nut varieties, and specimens introduced by USDA plant explorers from the late 19th and early 20th centuries.
The collection spans the years 1886 to 1942. The majority of the paintings were created between 1894 and 1916. The plant specimens represented by these artworks originated in 29 countries and 51 states and territories in the U.S. There are 7,497 watercolor paintings, 87 line drawings, and 79 wax models created by approximately 21 artists.
Lithographs of the watercolor paintings were created to illustrate USDA bulletins, yearbooks, and other publications distributed to growers and gardeners across America.
Today, the collection is preserved in NAL's Rare and Special Collections, where it serves as an important research tool for a variety of users, including horticulturists, historians, artists, and publishers. In 2010 and 2011, the entire printed collection was digitized to improve public access to this valuable resource, and to better preserve the paintings by reducing the need for researchers to handle them. Today, the whole collections is searchable.
In 1886, the United States Department of Agriculture (USDA) established the Division of Pomology to oversee the collection and distribution of new varieties of fruits, and to disseminate information to fruit growers and breeders. USDA commissioned artists to create technically accurate illustrations of newly introduced cultivars for the division's publications. In 1887, William H. Prestele was appointed as the first artist for the Division of Pomology. Henry E. Van Deman, division chief, explained the importance of Prestele's appointment in his 1887 Report of the Pomologist:
Up to August 1, when Mr. Prestele took his place here, there was no one to make drawings of fruits which were being daily received for study and comparison...but since then a part of the drawings have been made in India ink, and others have been reproduced in water-colors, all in the most skillful manner, showing the natural size, shape, and color of both exterior and interior of the fruit, with the leaves and twigs characteristic of each. These are invaluable for comparison and reference, and a portion for publication.
Over the years, other artists were also assigned to the division and their watercolors were used for lithographic reproductions in USDA publications and as scientific documentation of research results. Although some of the watercolor paintings are not signed, we know of 21 artists (nine of whom were women) who contributed to this important resource.

You may not have heard of USDA plant explorers David Fairchild and Palemon Howard Dorsett, but they are among those who have had the greatest impact on what we eat in the United States. Now a silent film of their 1925–26 collecting trip to Ceylon (Sri Lanka), Sumatra, and Java has been found by the National Agricultural Library (NAL).
One hundred years ago, the national cuisine was rather plain—heavy on meat, potatoes, and cheeses, and with a very limited palette of fruits and vegetables. But Fairchild, Dorsett, and other USDA plant explorers trekked across the world to find new crops and ornamental plants for the country.
Fairchild alone is credited with the introduction of more than 200,000 exotic plants and crop varieties, including avocado, flowering cherry trees, hops, horseradish, kale, nectarines, papaya, and pistachios.
Dorsett is best known for collecting germplasm that has helped to build soybeans into a $40 billion-a-year U.S. crop.
In 1925, Fairchild and Dorsett led a USDA expedition to Ceylon, Sumatra, and Western Java, during which they scoured markets, botanical gardens, farms, roadsides, and even beaches to collect seeds and plant specimens. Accompanying the explorers was Dorsett's son Jim, whose job was to document the trip photographically.
Jim Dorsett was equipped with a then state-of-the art Sept camera that could take sharp still photos, fast-action sequence photos, and movies. Fairchild was the first to acknowledge that Jim Dorsett's equipment and techniques were far superior to his own. But he was not the last, as National Geographic hired Jim Dorsett soon after he returned from the expedition.
Recently, NAL's Special Collections staff began an inventory of their 16-mm films. They discovered a poorly labeled film canister. Once they began watching, it didn't take long into the 21:06-minute silent film to realize what they had.
“It is an amazing film,” says botanist Karen Williams with the Agricultural Research Service's National Germplasm Resources Laboratory. “It offers rare insights into how people were using plants at that time. Were they using the same plants in different ways than is now common in the region? In addition, they included natural habitats in the film. Botanists may be able to make comparisons between some of the plants that are identifiable in the film and plants known to occur in the same region today—or they may find that some are rare or even extinct today,” she adds.
A collaboration between NAL and the Fairchild Tropical Botanic Gardenin Coral Gables, Florida, has begun to interpret the botanical and historical context of the film.
“A fascinating movie to watch and a real jewel in ethnobotany, particularly when you consider it was made in the early 20th century,” says Fairchild Tropical Botanic Garden adjunct faculty and Florida International University professor Javier Francisco-Ortega. “The film covers so many things: new crops, plants as avenues to teach, ethnography, plants as tools and building materials. There is one sequence where you see them collecting a certain bamboo and then a man building with it.”
You can watch a digitized version of the entire film on YouTube Those were the days of really getting into travel.
Paula Sewell has biographies of three of the USDA explorers - David Fairchild, Frank Meyer (Meyer Lemon) and Wilson Popenoe (Pop Enoe). Turns out Popenoe retired to Antigua Guatemala and Tony Brown of Carpinteria went to the guru to learn more about the cherimoya and how best to nurture it here and from there the crop flourished and the whole family was involved - Johnny, Peter and Emily.

WASHINGTON, June 26, 2019 – USDA's Natural Resources Conservation Service (NRCS) and the University of California at Davis Soil Resource Laboratory today announced the release of the iOS and Android SoilWeb app, version 2.0. The app now has a cleaner and more modern interface with GPS-location-based links to access detailed digital soil survey data (SSURGO) published by the NRCS for most of the United States. The newly updated SoilWeb smartphone application is available as a free download on Google Play 
and Apple App Store .
“SoilWeb reached a new milestone this year when it was integrated with Google Maps and designed to scale across any device, desktop, tablet or smart phone,” said NRCS Chief Matthew Lohr. “SoilWeb app is a portable interface to authoritative digital soil survey data from NRCS, giving users access to practical detailed scientific soil information on the go.”
The SoilWeb app provides users with information relating to soil types that are associated with their location. The images are then linked to information about the different types of soil profiles, soil taxonomy, land classification, hydraulic and erosion ratings and soil suitability ratings. Identifying soil types is important to understanding land for agricultural production purposes and determining flooding frequencies and suitable locations for roads or septic tanks. SoilWeb provides gardeners, landscapers and realtors with information relating to soil types and how to optimally use the soil. Although soil survey information can be used for general farm, local, and wider area planning, a professional onsite evaluation may be needed to supplement this information in some cases.
“SoilWeb is a great way to understand the landscape you live in,” said Anthony O'Geen, UC Davis Professor and Cooperative Extension Specialist in the Department of Land, Air and Water Resources. “Producing food, constructing structures and maintaining landscapes all depend on this little understood, but critical outermost layer of the earth's crust, the soil.”
The app gives access to valuable scientific data through modern technology. All the soil information in SoilWeb was collected from the National Cooperative Soil Survey, organized by the NRCS, and accesses soil survey information the agency has been collecting since the 1890s. The resulting database, the largest such in the world, makes it possible for soil scientists to generate specialized maps using computer-aided techniques.
O'Geen developed SoilWeb with NRCS Soil Scientist Dylan Beaudette, in 2010 when Beaudette was a Ph.D. student at UC Davis. The app was a popular download, but by 2017 was no longer in compliance with requirements set by Apple and Google. Frequent users of SoilWeb had to rely on the web-based version from 2017 to June 2019. Any users with the older version on their phone can do a simple update to access the newest version. The app is a product of a 14-year partnership between NRCS and UC Davis College of Land, Air and Water Resources.

Here is a really good introduction to the use of the on-line Soil Survey from USDA. Maybe it is easier to follow than blogs I have posted in the past.
WASHINGTON — “Soil don't get no respect,” Rodney Dangerfield might have said (but didn't). Perhaps you know your state bird or flower, but do you know your state soil?
Well, in recent years soil has begun to get more respect. Since the celebration of the Soil Survey Centennial back in 1999, each state has been given its own official state soil. It was in 1899 that the U. S. Department of Agriculture started its survey of all the soils in the country.
SOILS COME IN MANY ‘Flavours'
You might wonder what a “soil survey” really is. Isn't it all just dirt — some perhaps stickier, or redder or deeper — that lies beneath forest, meadow, farm, home and garden?
There you go again. Not enough respect.
In fact, soils are distinctive, as different from each other as robins are from blue jays. These differences are hard to appreciate, of course, because soil is mostly underground, hidden from view. But if you were to dig some holes a few feet deep and then look carefully at their inside surfaces, you would find that soils are made up of layers of varying thickness, called horizons. One soil might differ from the next not only in the thickness of its horizons, but also in their appearance and feel.
Horizons might be as white as chalk, as red as rust, or as dark brown as chocolate. A horizon might be cement-hard, gritty with sand, or stuff for sculpture. And if you were to tease the dirt along one edge of the hole so it falls away naturally — wow! — each horizon would reveal its particles clumped together in arrangements like plates, blocks or prisms. Such information, and more, has allowed soils to be classified, much as birds, flowers and other living things are.
CLASSIFYING SOILS
Modern soil classification goes back only a few decades, when all the world's soils were grouped taxonomically into a dozen “orders.” Differences among orders reflect the formative influence of a particular combination of climate, plants and animals, topography, time and original rock material.
Just as all vertebrate animals are huddled together by biologists into smaller groupings (mammals, say) and those groupings into still smaller ones, so each soil order is divided and subdivided to include more distinctly different soils. At the end of the dividing and subdividing, you end up with a “soil series” identified with a proper name — like the Haven series in my vegetable garden, for example.
YOUR STATE'S AND BACKYARD'S SOIL
A particular soil becomes an official state soil by being widespread within the state; being distinctive chemically or physically; having some degree of name recognition; and, of course, getting a legislative stamp of approval. Examples include soils like West Virginia's Monongahela soil, Texas' Houston Black soil, California's San Joaquin soil and New York's Honeoye soil.
The job, now, of these “ambassadors” of the benevolent underworld is to rekindle awareness of soil's value as a natural resource that can only be renewed very slowly. Soil provides food, shelter, clothing and more, yet it is being lost at alarming rates to everything from blacktop to erosion.
Out in the garden this spring, dig a hole deep and wide enough that you can see and appreciate at least some of the various and distinctive horizons.
Then, if you want the name and a detailed description of that soil — or any soil — look at the maps and descriptions in the Soil Survey Reports issued by the U. S. Department of Agriculture, Natural Resource Conservation Service (NRCS). Search online for “soil survey nrcs” and you'll find links to soil maps for counties throughout the U.S. Or go to the link to “web soil survey.” At this site, you can type in a street address around which you “draw” your area of interest (AOI). The site will delineate the names and descriptions of soils within that AOI.
