Introduction To Agroecology: Principles And Practices
$135.00
Agroecology is defined by the OECD as "the study of the relation of agricultural crops and environment." Dalgaard et al. refer to agroecology as the study of the interactions between plants, animals, humans, and the environment within agricultural systems. Francis et al. also use the definition in the same way but thought it should be restricted to growing food.

Agricultural Soil Science
$135.00
Prior to the development of pedology in the 19th century, agricultural soil science was the only branch of soil science. The bias of early soil science toward viewing soils only in terms of their agricultural potential continues to define the soil science profession in both academic and popular settings as of 2006.

Agricultural Technology
$135.00
A major turning point for agricultural technology is the Industrial Revolution, which introduced agricultural machinery to mechanize the labor of agriculture, greatly increasing farm worker productivity. In modern mechanized agriculture powered machinery has replaced many farm jobs formerly carried out by manual labor or by working animals such as oxen, horses, and mules. Advances in the 19th century included the development of modern weather forecasting and the invention of barbed wire. Improvements to portable engines and threshing machines led to their widespread adoption.

History Of Agriculture
$135.00
Agriculture began independently in different parts of the globe and included a diverse range of taxa. At least eleven separate regions of the Old and New World were involved as independent centers of origin. The development of agriculture about 12,000 years ago changed the way humans lived. They switched from nomadic hunter- gatherer lifestyles to permanent settlements and farming.

Green Revolution
$135.00
Green Revolution, the great increase in the production of food grains that resulted in large part from the introduction into developing countries of new, high-yielding varieties, beginning in the mid-20th century. Its early dramatic successes were in Mexico and the Indian subcontinent. The new varieties require large amounts of chemical fertilizers and pesticides to produce their high yields, raising concerns about cost and potentially harmful environmental effects. Poor farmers, unable to afford the fertilizers and pesticides, have often reaped even lower yields with these grains than with the older strains, which were better adapted to local conditions and had some resistance to pests and diseases.

Advances in Agronomy
$135.00
Agronomy is the science and technology of producing and using plants by agriculture for food, fuel, fiber, chemicals, recreation, or land conservation. Agronomy has come to include research in plant genetics, plant physiology, meteorology, and soil science. It is the application of a combination of sciences such as biology, chemistry, economics, ecology, earth science, and genetics. Professionals of agronomy are termed agronomists.

Agriculture In Society
$135.00
Agrarian societies are dependent upon agriculture and have been around for more than 5,000 years. Imagine a society of farmers and you'll have a pretty good idea of what an agrarian society is all about. An agrarian society is a society whose economy and wealth are primarily based upon agriculture. Agrarian societies have been around for at least five thousand years. In fact, they still exist today. Nearly every civilization has spent some time as an agrarian society. The ancient Egyptian, Indian, Chinese, and Mayan societies were agrarian. Today, the poorest of the lesser-developed countries are pretty much agrarian societies.

Agriculture And The Environment
$135.00
The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. The environmental impact of agriculture varies widely based on practices employed by farmers and by the scale of the practice. Farming communities that try to reduce environmental impacts by modifying their practices will adopt sustainable agriculture practices. The negative impact of agriculture is an old issue that remains a concern even as experts design innovative means to reduce destruction and enhance eco- fficiency.
