Lagoons hold less over time | Manure storage may reach capacity before expected, typically due to increases in precipitation, buildup of solids, or increases in animal numbers. Solutions can include expanding the existing lagoon or building, satellite ponds, or agreements with neighboring farms. | Article
Connecting the dots with manure | As this Wisconsin dairy has invested in changes, from anaerobic digestion to drying separated solids for bedding to using a compost bedded pack for heifers, it’s seen improvements in milk and crop production. | Article
Poultry litter brings long-term benefits | Researchers for an Iowa study compared the effects of applying UAN fertilizer and poultry manure for 20 years. The manure applied at agronomic rates had improved soil health, nitrates in tile drain runoff, and crop yields, but soil phosphorus levels were higher. | Article
Poultry litter provides nutrients, risks | Poultry litter N and P levels can vary widely depending on bedding, poultry type, diet, and other factors. So before applying it to forages, which require 3-4 times more N than P, it should be analyzed and an application plan made. | Article
Manure’s contribution to carbon footprints | While animal manures contribute to greenhouse gas emissions on farms, the amount varies depending on storage and handling practices. | Article
