Sadia swine manure lagoon treatment case study
The Problem SADIA, a major integrated hog producer located in the Santa Catarina province of Brazil requested permission to conduct a test to determine the effectiveness of Nordevco Associates’ technology to improve conditions in their manure storage lagoon at a facility located in Concordia. Nordevco’s solution was applied by the producer and all testing and analyses were carried out ...

The ManureEcoMine pilot installation: advanced integration of technologies for the management of organics and nutrients in livestock waste
Manure represents an exquisite mining opportunity for nutrient recovery (nitrogen and phosphorus), and for their reuse as renewable fertilisers. The ManureEcoMine proposes an integrated approach of technologies, operated in a pilot-scale installation treating swine manure (83.7%) and Ecofrit® (16.3%), a mix of vegetable residues. Thermophilic anaerobic digestion was performed for 150 days, ...

Zonejection: Conservation tillage manure nutrient delivery system
Manure application in minimum till (MT) systems is a challenge worthy of attention because residue cover is a keystone for environmental protection. To develop a system combining zone tillage and manure application into one operation (zonejection), two experiments were conducted. In Exp. 1, liquid swine manure (LSM) was applied in fall or spring for two site years (A, B). In Exp. 2, LSM was ...

Nitrous oxide production in an eastern corn belt soil: sources and redox range
Nitrous oxide derived from soils is a main contributor to the greenhouse gas effect and a precursor to ozone-depleting substrates; however, the source processes and interacting controls are not well established. This study was conducted to estimate the magnitude and source (nitrification vs. denitrification) of N2O production as affected by the form of N fertilizer, soil water content, and redox ...

Cover crop effects on the fate of N following soil application of swine manure
Abstract Cereal grain cover crops increase surface cover, anchor corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] residues, increase infiltration, reduce both rill and interrill erosion, scavenge excess nutrients from the soil, and are easily obtained and inexpensive compared to other cover crop options. The use of cereal grain cover crops in fields where manure application occurs ...

Enhancing nutrient cycling by coupling cover crops with manure injection
Coupling winter small grain cover crops (CC) with liquid manure injection may increase manure nutrient capture. The objectives of this research were to quantify manure injection effects using target swine (Sus scrofa) manure N rates of 112, 224, and 336 kg N ha–1 on CC plant density, fall and spring shoot biomass, N, P, and K uptake and subsequent corn (Zea mays L.) yield. A winter rye (Secale ...

Dietary protein and cellulose effects on chemical and microbial characteristics of swine feces and stored manure
Received for publication January 24, 2008. The objectives of this study were to investigate the effects of dietary crude protein (14.5 or 12.0%) and cellulose (8.7 or 2.5%) levels on composition of feces and manure after 8 wk of diet feeding and storage. Pigs were fed twice daily; after each feeding, urine and feces were collected and added to manure storage containers. On weeks 2 and 8 after ...

The Biophosphate Plant
Biophosphate pellets from pig manure for use in low-phosphate agricultural areas The Ecoson Biophosphate plant produces green gas from animal manure in a sustainable way, and a natural, phosphate-rich organic fertilizer pellet for use in low-phosphate agricultural areas. The plant has a processing capacity of 100,000 tonnes of manure per year. With this, approximately 6,000 tons of biophosphate ...
