Lagoon treatment for manure case study
Are you getting a scale build up in your recirculation system from your manure holding ponds (lagoons)? Is it calcium carbonate or struvite (magnesium-ammonia-phosphate) crystals? In some CAFO sites, they will use anaerobic lagoons to reduce the amount of manure that they need to treat. In a zero oxygen environment the anaerobic bacteria will take the manure which is loaded with nutrients and ...

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 ...

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) ...

Runoff Phosphorus loss immediately after poultry manure application as influenced by the application rate and tillage
Excessive or N-based application of poultry manure for crops may result in significant risk of P loss with surface runoff. This study assessed P loss immediately after poultry manure application to soybean [Glycine max (L.) Merr.] residue with and without tillage at eight Iowa fields. Manure from chickens (Gallus gallus domesticus) or turkeys (Melleagris gollopavo) was applied at intended rates ...
