Fertilization of Dryland and Irrigated Soils
Author: J. Hagin
Publisher: Springer Science & Business Media
ISBN: 3642683274
Category : Technology & Engineering
Languages : en
Pages : 197
Book Description
Much has been learned about the proper and judicious use of fertilizers. Fertilizer application by farmers has grown from an art to a science. As food producers have strived to increase crop yields by overcoming nutrient deficiencies the use of fertil izers has increased dramatically. This has created a large chemical industry capable of supplying the needed plant food elements. A more complete understanding of soil chemistry and plant nutrition has led to greater fertilizer use with improved fertilization methods and crop cultural practices. Improved fertilizer technology has led to the production of more efficient forms of fertilizer. The modem fertilizer industry and with it fertilization practices began in the humid countries of the world. The use of fertilizers in arid and semiarid regions was later in development, although agriculture had its beginning in semiarid and arid regions. The development offertilizer use is parallel to industrial development in various areas of the world.

Home in the Woods
Author: Eliza Wheeler
Publisher: Penguin
ISBN: 0399162909
Category : Juvenile Fiction
Languages : en
Pages : 42
Book Description
This stunningly beautiful picture book from New York Times bestselling author-illustrator Eliza Wheeler is based on her grandmother's childhood and pays homage to a family's fortitude as they discover the meaning of home. Eliza Wheeler's gorgeously illustrated book tells the story of what happens when six-year-old Marvel, her seven siblings, and their mom must start all over again after their father has died. Deep in the woods of Wisconsin they find a tar-paper shack. It doesn't seem like much of a home, but they soon start seeing what it could be. During their first year it's a struggle to maintain the shack and make sure they have enough to eat. But each season also brings its own delights and blessings--and the children always find a way to have fun. Most importantly, the family finds immense joy in being together, surrounded by nature. And slowly, their little shack starts feeling like a true home--warm, bright, and filled up with love.

Fertilizers and Environment
Author: Claudio Rodriguez Barrueco
Publisher: Springer Science & Business Media
ISBN: 9400915861
Category : Technology & Engineering
Languages : en
Pages : 539
Book Description
Food production remains the highest agricultural priority, subject to the constraint that it be done in harmony with nature, or at least with minimum environmental pollution. The amount of fertilizer applied can be controlled using modern application techniques, including soil and crop management, guaranteeing higher economic profit and lower environmental cost. It is in such a context that the present book addresses the efficient and rational use of mineral and organic fertilizers while preserving environmental quality. The book discusses the impact on surface and groundwaters, soils and crops, and experience of nitrate leaching, denitrification, ammonia volatilization, heavy metal pollution, agricultural and urban waste management, and international and national legislation. Audience: Agronomists, environmentalists, soil and food chemists, ecologists, policy makers, and managers in the fertilizer industry concerned with the trend of public opinion.

Fertigation
Author: P Soman
Publisher: New India Publishing Agency
ISBN: 9390591147
Category : Technology & Engineering
Languages : en
Pages : 4
Book Description
Fertigation requires a thorough understanding of the science behind the technology to make it deliver the immense possibility it offers in crop production. Though the idea of fertigation existed from the times of solution culture, it did not receive the necessary attention from among plant nutritionists and agronomists when it reappeared in the context of micro irrigation. Fertilizer application in field agriculture has also not developed as a precision technology. Recommendations of the quantum of fertilizers required for a crop, at least in India are not based on current varieties of the crops, nor have they anything to do with the growth rate and developmental changes occurring while a crop is managed by the grower. Most of the fertilizer recommendations are itself very old and efforts to make them relevant to the current growing conditions, soil status, crop variety and crops reaction to the environment etc. are very limited. It is even worse when growers follow traders' recommendations whose idea is to sell more the fertilizer they supply. Not only lower yields and very low fertilizer use efficiencies, but the deterioration of soil and water bodies are the results.
