Weed Seeds of the Great Plains
ISBN: 9780700606511 / Angielski / Twarda / 152 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Seeds, as small and unobtrusive as they seem, are an essential part of the life cycle of plants. In addition, they are useful for indentification of plants and, in fact, are often superior for that purpose that other parts of a plant. Thant's because seedds have distinctive characteristics, tend to outlast all other plant parts, and vary little within a species-unlike other parts such as leaves. Since weeds interfere with the growth, harvesting, and quality of crops, Linda Dvais says, the ability to identify weed seeds before they are indavertently planted affords an economic advantage. Other...

A Green and Permanent Land: Ecology and Agriculture in the Twentieth Century
ISBN: 9780700610662 / Angielski / Twarda / 232 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Once patronized primarily by the counterculture and the health food establishment, the organic food industry today is a multi-billion-dollar business driven by ever-growing consumer demand for safe food and greater public awareness of ecological issues. Assumed by many to be a recent phenomenon, that industry owes much to agricultural innovations that go back to the Dust Bowl era. This book explores the roots and branches of alternative agricultural ideas in twentieth-century America, showing how ecological thought has challenged and changed agricultural theory, practice, and policy from...

ISBN: 9780792310952 / Angielski / Twarda / 380 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Many agricultural crops worldwide, especially in semi-arid climates, suffer from iron deficiencies. Among plants sensitive to iron deficiency are apples, avocado, bananas, barley, beans, citrus, cotton, grapes, peanuts, pecans, potatoes, sorghum, soybeans, and numerous ornamental plants. Deficiencies are usually recognized by chlorotic, in new leaves and are typically found among sensitive crops grown in calcareous or yellowed, interveinal areas soils which cover over 30% of the earth's land surface. Iron deficiency may lead, in extreme cases, to complete crop failure. In intensive...

Iron Nutrition in Soils and Plants: Proceedings of the Seventh International Symposium on Iron Nutrition and Interactions in Plants, June 27-July 2, 1
ISBN: 9780792329008 / Angielski / Twarda / 401 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Iron is a major constituent of the earth crust. However, under alkaline conditions commonly found in arid and semi-arid environments iron becomes unavailable to plants. When plants are affected by a shortage of iron their leaves become yellow (chlorotic), and both plant growth and crop yield are reduced. The roots of plants affected by iron deficiency may develop a series of responses directed to improve iron uptake, such as increased proton excretion and iron reduction capabilities or excretion of iron chela tors called siderophores. Iron deficiency affects major crops worldwide, including...

ISBN: 9780792336082 / Angielski / Twarda / 507 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In the coming decades the world will need to more than double its food and feed production, almost all of the increase being needed in developing countries. This has socioeconomic and biophysical implications. Traditional component and commodity research addresses overly narrow issues at too small a scale. Rural development needs an eco-regional approach that integrates biophysical and socioeconomic work on cropping systems, livestock, the environment, and natural resources.
This book contains the papers, response papers and discussion report of a five-day seminar on eco-regional... In the coming decades the world will need to more than double its food and feed production, almost all of the increase being needed in developing coun...

Sulphur in Agroecosystems
ISBN: 9780792351238 / Angielski / Twarda / 223 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This is the second volume in the series Nutrients in Ecosystems. Sulphur as an essential plant nutrient has received little attention. This is explained by the facts that sulphur was obviously in sufficient supply from the atmosphere, from soil and as a by-product in mineral fertilizers. Increases in the yield potential and thus in the nutrient requirement of modern crops, however, as well as remarkable changes in SO2 emissions by private households, power stations and industry, associated with legislative measures to reduce air and water pollution, have altered the...

Current Advances in Coconut Biotechnology
ISBN: 9780792358237 / Angielski / Twarda / 440 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The coconut palm occupies a significant place in the world economy as an important subsistence crop in all the areas in which it is grown. Relatively few countries are able to export any quantity of coconut products because of increasing home demands coupled with low productivity. Yields are generally well below potential despite recent developments with improved planting stock and agronomic practices. In the last 50 years, both these aspects have received considerable attention, but the focus is shifting to investigate how the use of recently developed biotechnological techniques- can...

The Farming Game
ISBN: 9780803275829 / Angielski / Miękka / 246 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In cantankerous opinions, hard-headed advice, and free-swinging sketches of real farmers, Bryan Jones addresses everyone who feels the pull of the land. He accepts the emotional appeal of "going back to the land" and then takes the unconventional stand that, above all, farming can be a good way to make money. Against the grain of public policy that, he maintains, encourages big agriculture, Jones works out how a shrewd, stubborn small farmer can still make a go of it. His keen-eyed sketches of farmers at work show the variety of ways a farmer may succeed or fail. Even his own neighborhood,...
