Phytase supplemented poultry diets affect soluble phosphorus and nitrogen in manure and manure-amended soil
Understanding P and N dynamics in manure-amended soil is essential for estimating the environmental impact of manure utilization in land applications. A laboratory incubation study was conducted to assess, (i) the effect of feeding a standard Australian commercial diet, and diets modified with phytase supplementation and reduced nonphytase phosphorus (NPP), on the concentrations of P and N (total ...

Critical source area management of agricultural phosphorus: experiences, challenges and opportunities
The concept of critical source areas of phosphorus (P) loss produced by coinciding source and transport factors has been studied since the mid 1990s. It is widely recognized that identification of such areas has led to targeting of management strategies and conservation practices that more effectively mitigate P transfers from agricultural landscapes to surface waters. Such was the purpose of P ...

Evaluation of Soil Physical Properties as Influenced by Various Green Manuring Legumes and Phosphorus Fertilization under Rain Fed Conditions
A field experiment was conducted under rainfed environment of Pothowar region of Pakistan to assess physical properties of soil as influenced by various green manure legumes (sesbania, cluster bean and rice bean) and different P levels (0, 30, 60, 90 kg P2O5/ha). Highest fresh biomass was observed in sesbania (23 t/ha) followed by cluster bean (19 t/ha) and lowest in rice bean (17 t/ha). Maximum ...

What are the advantages of using rabbit manure as organic fertilizer?
Nutrient content of rabbit feces Rabbit manure is a kind of high efficient organic fertilizer, the content of nitrogen, phosphorus and potassium is significantly higher than other animal manure. The nitrogen content of rabbit manure is 1.53 times of chicken manure, 3.29 times of sheep manure, 3.83 times of pig manure, the phosphorus content is 2.88 times of chicken manure, 4.6 times of sheep ...

Effects of dried distillers` grains with solubles (wheat-based) in feedlot cattle diets on feces and manure composition
The use of dried distillers' grains with solubles (DDGS) in feedlot cattle (Bos taurus) diets is increasing as the bio-ethanol industry expands. This study investigated how wheat (Triticum aestivum L.) DDGS-based diets impact feedlot cattle nutrient and volatile fatty acid (VFA) excretion. Feedlot heifers were fed DDGS at 0 (Control) 20, 40, 60% or 60% + Ca (1% limestone) of dietary dry matter. ...

Estimating Phosphorus loss in runoff from manure and fertilizer for a Phosphorus loss quantification tool
Nonpoint-source pollution of fresh waters by P is a concern because it contributes to accelerated eutrophication. Given the state of the science concerning agricultural P transport, a simple tool to quantify annual, field-scale P loss is a realistic goal. We developed new methods to predict annual dissolved P loss in runoff from surface-applied manures and fertilizers and validated the methods ...

Linking Wisconsin dairy and grain farms via manure transfer for corn production
One relatively under-used manure management strategy employed by dairy farmers is to transport and apply manure onto the fields of nearby grain farmers. While this system offers advantages to both parties, little of the existing research on manure management has been conducted on grain farms. As part of an effort to link grain and livestock farms in southern Wisconsin, 20 on-farm trials were ...

Transport and fate of phosphorus during and after manure spill simulations
Animal manure spills contribute to P loading of surface waters and little is known about the effectiveness of the current manure spill clean-up methods to mitigate P contamination. Manure spill clean-up consists of containing, removing, and land applying the contaminated water column, while P-enriched fluvial sediments remain in place. Therefore, the objectives of this study were to (i) ...

Dairy diet Phosphorus and rainfall timing effects on runoff Phosphorus from land-applied manure
Surface-applied dairy manure can increase P concentrations in runoff, which may contribute to eutrophication of lakes and streams. The amount of dietary P fed to dairy cows (Bos taurus) and the timing of a rain event after manure application may further affect runoff P losses. The objective of this study was to examine dietary P supplementation effects on manure and runoff P concentrations from ...

Unlocking the potential of poultry manure
The poultry industry is one of the largest and fastest-growing agro-based industries in the world. At the same time, the growth brings along a number of environmental problems. One of the major environmental problems is the accumulation of large amounts of wastes, e.g. manure. In order to mitigate these problems new economically sustainable technologies are needed. Manure has often been referred ...

Efficient Manure Separation: Screw Press vs. Slope Screen Separator
In the realm of agricultural and livestock farming, the responsible management of manure is of paramount importance. Manure, a valuable resource rich in organic matter and nutrients, can be a double-edged sword for farmers. On one hand, it serves as a potent natural fertilizer; on the other, its mismanagement can lead to environmental issues. To address this challenge, farmers have turned to ...
