How to Protect Value in the Pit
Manure management plays a central role in the overall efficiency of swine operations. Whether manure is land-applied or hauled off-site, conditions in the pit influence how manure behaves at pump-out, how much effort is required to move it, and how predictable the process is from one cycle to the next.
When solids settle and nutrients separate, pits tend to lose consistency. Agitation becomes more demanding, storage capacity is reduced, and manure quality varies from load to load. In operations that land-apply manure, this often shows up as reduced fertilizer value. In others, it appears as higher handling costs and less control at clean-out.
The questions below reflect common issues producers raise when looking to improve pit performance and maintain consistency over time.
Q: Why does manure from swine pits often underperform as fertilizer?
In many pits, nutrients are not evenly distributed. Solids settle to the bottom as sludge, and to the top as surface crust, creating a stratification within the pit. As a result, manure applied to the field may vary significantly from one load to the next. Some areas receive more nutrients than intended, while others receive less.
Q: How do pit solids affect fertilizer value?
When solids accumulate on the surface or pack at the bottom, nutrients become unevenly distributed. Phosphorus, nitrogen, and micronutrients no longer remain suspended throughout the pit. In these conditions, manure samples may not accurately represent what is ultimately applied, leading to inconsistent crop response and less reliable nutrient planning.
From a handling standpoint, solids accumulation prolongs agitation time, fuel use, and pumping effort.
For producers looking to improve uniformity and reduce pumping challenges, biological pit treatment programs are often used to help maintain suspension and reduce solids accumulation.

Q: What does “better manure” actually look like?
Better-performing manure is more uniform. Nutrients remain suspended rather than separating into layers, and solids are broken down instead of accumulating over time. This improves pumpability and helps ensure more consistent application, whether manure is applied to cropland or removed from the site.
In the field, uniform manure typically leads to more predictable crop response and simpler nutrient planning. In many cases, it also reduces the need for supplemental fertilizer.
Q: Can microbial products really improve fertilizer performance?
Yes, when they are designed specifically for swine manure systems. Targeted microbial programs support the biological breakdown of organic solids, help stabilize nutrients, and reduce losses such as ammonia volatilization.
Rather than relying solely on extended agitation, biological treatment works gradually to improve manure consistency and pit performance over time.
Q: How does PIT PERFECT fit into this process?
PIT PERFECT’s microbial blend takes up nutrients in the process, building what’s referred to as a bio-active manure. By reducing stratification, it supports more consistent nutrient distribution and improves manure handling at pump-out and land application.
Producers also report reduced agitation requirements and improved use of existing pit storage capacity, making manure management more predictable from cycle to cycle.

Q: What changes do producers notice in the field?
Producers using biological pit treatment programs often see:
- More uniform nutrient application
- Improved soil biology and structure
- Better nutrient uptake by crops
- Stronger, more consistent yields
- Reduction of odor during application
In many cases, improved manure consistency results in approximately 18% higher fertilizer value, helping offset the need for commercial fertilizer inputs.
Q: Is this only about crops, or does it help the farm overall?
Improved pit performance affects the entire operation. Healthier pits tend to produce corrosive gas levels and release flammable gases trapped in solids, improve barn air quality, create safer working conditions, and safer living conditions for hogs.. Odor issues are often reduced, and pumping operations become easier to manage.
When manure behaves more predictably, it shifts from being a recurring challenge to a more manageable part of the operation.
Q: What’s the biggest mistake producers make with manure management?
Waiting till there’s a significant problem. Treating manure only when pits are full limits what biology can do. Programs that start earlier—especially after pumpout—help protect nutrient value long before application season.
Turning Waste into an Asset
Manure is already part of every swine operation. The difference lies in how well it is managed over time. With the right biological approach, manure becomes easier to handle, more consistent at application, and more valuable as a nutrient resource.
For producers looking to reduce agitation, improve predictability, and protect manure value throughout the year, biological pit treatment can be a practical part of a long-term management strategy.
