Pests And Diseases
$135.00
Together pests and diseases cause up to 40% yield losses every year. The animal groups of the most significant importance as agricultural pests are (in order of economic importance) insects, mites, nematodes, and gastropod mollusks. Insects are responsible for two major forms of damage to crops. First, there is the direct injury they cause to the plants as they feed on the tissues; a reduction in leaf surface available for photosynthesis, distortion of growing shoots, a diminution of the plant's growth and vigor, and the wilting of shoots and branches caused by the insects' tunneling activities.

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.

Agricultural Resources
$135.00
Agricultural resources means the land and on-farm buildings, equipment, manure processing and handling facilities, and processing and handling facilities that contribute to the production, preparation, and marketing of crops, livestock, and livestock products as a commercial enterprise, including a commercial horse boarding operation, a timber operation, compost, mulch or other biomass crops, and commercial equine operation.

Organic Farming and Gardening: Systems and Approaches
$135.00
Organic farming – an alternative agricultural system that relies on fertilizers of organic origin such as compost, manure, green manure, and bone meal and places emphasis on techniques such as crop rotation and companion planting. Biological pest control, mixed cropping, and the fostering of insect predators are encouraged. In general, organic standards are designed to allow the use of naturally occurring substances while prohibiting or strictly limiting synthetic substances.
