Book Description
Both raw and digested FDM, and through 30 pore volumes, very little leaching of P at all. The soils receiving inorganic P retarded leaching the least, and the extent of retardation was related to the soils inherent P sorbing capacity through Al and Fe oxide content. ANOVA output revealed significant differences in P accumulation in the soils among P amendments and soils, as well as a P amendment * soil interaction. Duncan's Multiple Range Test showed the P accumulated in soils receiving inorganic P to be significantly less than those receiving raw or digested FDM. Precipitation with Ca and Mg contained in the FDM, entrapment of particulate P, and immobility of OM due to soil chemistry are the suspected explanations for the lack of P breakthrough in FDM amended columns. The precipitated P is not expected to be stable and will leach into the deeper soil horizons. This study highlights the differences in P behavior in soils when delivered through different mediums and the complexity of the soil chemistry regarding P when FDM is amended to soils. It also demands further research in this area to better understand the processes and consequences of P leaching where similar practices are employed.

Removal of Water-extractable Phosphorus from Dairy Manure
Author: Kathryn Elizabeth Lawson
Publisher:
ISBN:
Category : Dairy cattle
Languages : en
Pages : 83
Book Description
Phosphorus is an essential nutrient for life, but excess phosphorus in runoff from manure applied to agricultural fields can lead to negative environmental impacts such as harmful algal blooms. Water-extractable phosphorus (WEP) is correlated with phosphorus runoff from land-applied manure, but can change depending on the water content of a sample. Understanding how total phosphorus (TP) and WEP partition through livestock manure management systems can aid attempts in preventing phosphorus pollution of watersheds by increasing knowledge of how to remove it at its source. A number of dairy farms use solid-liquid separation in order to make the manure easier to handle. This produces a mostly solid material which can be re-used in the dairy barns as bedding for the cows, as well as a mostly liquid material which is applied to the fields. However, little is known about the partitioning of WEP through solid-liquid separation.

Inorganic Constituents in Soil
Author: Masami Nanzyo
Publisher: Springer
ISBN: 9811312141
Category : Nature
Languages : en
Pages : 188
Book Description
This open access book is a must-read for students of and beginners in soil science. In a well-organized and easy-to-follow manner, it provides basic outlines of soil minerals, new methods and recent developments in the field, with a special focus on visual aids. The chapters on primary minerals, secondary minerals, non-crystalline inorganic constituents and inorganic constituents sensitive to varying redox conditions will help readers understand the basic components of soils. Further, readers are introduced to new analytical methods with the aid of microscopy and recent developments in the field. Uniquely, the book features case studies on the identification and isolation methods for vivianite crystals from paddy field soils, as well as a useful procedure for identifying noncrystalline constituents such as volcanic glasses and plant opals, which can also be applied to other soils depending on the local conditions. Given its focus and coverage, the book will be useful to all readers who are interested in agronomy, plant production science, agricultural chemistry and environmental science. In addition, it can help biogeochemists further expand their research work on the rhizosphere of wetland plant roots, iron and phosphate dynamics, etc.
