Farmers also widely rely on credit cooperatives as a source of financing for both working capital and investments.

The events surrounding the spread of domesticated crops from Asia the spread of agriculture south-west Asia across the diverse landscapes and societies of early Europe, from the arid Mediterranean to the temperate shores of north-west Europe, involved a complex set of interconnected changes in lifestyle but in virtually all cases ended with land coming under the plough.

Archaeologists don't fully understand the nature of the transition in the disparate regions, but if we did, it may well offer clues to the reasons why farming based on the cultivation of a handful of plant species became the dominant way of life across Europe and the rest of the world.

But these cereal grains show that the much-debated spread inland occurred in fits and starts.

It seems agriculture arrived in the Balkans around 7950 BP then halted for approximately 800 years before spreading rapidly to north-west Europe, arriving with near synchronous dates in the Czech Republic and the Netherlands.

The USDA's National Agricultural Statistics Service (NASS) conducts hundreds of surveys every year and prepares reports covering virtually every aspect of U. The abundance of information produced has earned for NASS employees the title, "The Fact Finders of Agriculture."NASS offers a wide range of data sets.

Production and supplies of food and fiber, prices paid and received by farmers, farm labor and wages, farm finances, weather conditions, chemical use, and changes in the demographics of U. NASS publications cover a wide range of subjects, from traditional crops, such as corn and wheat, to specialties, such as mushrooms and flowers; from calves born to hogs slaughtered; from agricultural prices to land in farms.

The information is commodity specific and contains many category breakdowns including U. Browse NASS by subject: NOTE: Most items obtained from this page are subscribed to by the library and accessible only to Virginia Tech students, faculty, and staff.
