Soil And Fertilizer Concepts And Practices

by 楊秋忠, Soil And Fertilizer Concepts And Practices Books available in PDF, EPUB, Mobi Format. Download Soil And Fertilizer Concepts And Practices books, Agriculture builds upon the integration of crops and the environment, with which its yield depends strongly on a healthy soil foundation. With that in mind, the knowledge of the soil and fertilizer is crucial to maintaining an environment with optimal nutrients, water and oxygen for crop production. Soil is one of human's precious resources, the protection and nurturing of our soil is thus an integral part of sustainable development. Effective soil management is considered not only a technology, but also an art. In practice, to make use the full potential of the land, the management strategies need to take account of the differences and characteristics of the soil, plant and climate that are unique to each geographical location. Such an approach is increasingly more important nowadays because of the increasing loss of cultivable land and need of high quality agricultural products.

Download Valuing Nutrients In Soil And Water Concepts And Techniques With Examples From Iwmi Studies In The Developing World books, Despite the importance of nutrient-water interactions, they are often ignored in analysis. After discussing the interrelationships between soil nutrients and water and reviewing methods for determining nutrient balances, this report describes an array of available methods for soil nutrient valuation and provides a discussion of four nutrient valuation studies, which together cover a range of scales, perspectives, and geographic contexts. It also includes case studies from Ghana, Mexico, sub-Saharan Africa, and an examination of possible approaches to valuing soil organic matter and its various functions--an often ignored area in literature.
