Chuck RippRipp’s Dairy ValleyDane, Wisconsin


Ripp’s Dairy Valley

• 990 cow dairy– 100 dry cows– 1,800 head of youngstock

• 16 full-time employees– Including 6 family members

• 1,200 owned acres– 200 rented– 500-600 used for nutrient management plan

Ripp’s Dairy Valley • Located 20 miles from the state Capitol• Yahara Watershed Project:

• Goal is incorporate systems/regulations that allow agriculture and urban life to coexist

• Minimize nutrient run off mainly nitrogen and phosphorus from both agriculture and urban areas

Current Manure System• Manure is scraped daily into a channel to a “central

pit”• Pumped through a 2-stage sand separator• Separated manure pumped to another pit where the

digester then sucks the manure to the digester

Current Manure System • Dane County Manure Digester

– Community digester– Shared between 3 farms (2,500 cows total)

• “The digester will produce methane and that methane will be used to power generators that will churn out $2 million a year in electricity, enough to allow Alliant Energy to power 2,500 homes,” (WI State Journal, 2011)

Current Manure System

• Manure sits at digester for 28 days• Liquids are returned back to the dairy daily• This liquid is called centrate

– Centrate is mostly liquids (with minimal fibers) and is combined with used parlor water to clean sand

– This process recycles about half of the water on the farm!


What’s Working?• Biodigester/Sand Separator

– Before digester, sand cost $1,400 per week– After digester/sand separator, sand cost

$320 per week– We believe there is nothing better for cow comfort– We can suck lagoon out without having to scoop sand

and apply it to the fields

Other Benefits • Manure that is spread on fields has reduced

odor – This is HUGE because it is hauled close to 3 different

surrounding villages

• This process removes about 50-55% of the phosphorous– Has the potential to remove 60-65% P when the

centrifuge is running correctly


Challenges• Sand separator not working correctly• Mechanical challenges

– Pumps/Moving parts

• Temperature effects– In summer, manure because more watery and the

pump tends to grab more sand

• Someone on call 24/7• Biodigester not working, then can’t pump

manure• Plugged lines

Advantages• Methane pulled off so manure is not as odorous

• Pulling phosphorus out-now can apply more manure based on NMP

• Love sand bedding for cows

• Environmentally friendly– Yahara Watershed


Looking to the Future • Everyone needs a NMP and need to follow it

• Plan your work and work your plan

• Precision ag technologies• Cost justified?

• Cover crops• Focus on areas where cover crop can hold back run off• Early Fall- Get manure on and plant cover crop• Think outside of the box with cover crops and rotations

• We cannot expand cow numbers without knowing where our manure is going to go

Final Thoughts

• Farming is a business• Be proactive and environmentally correct!

• Be open to evaluate new technologies• People are watching you

• Transparency & Honesty!

• Appearance is everything• Manure is always yours…take responsibility for

it!


Thank You

The WORM POWER Story

Large-scale Vermicomposting• Was approached by an entrepreneur• Business proposal was highly scrutinized• Not afraid to let someone else take the risk and reap

the financial rewards• Very little risk on our part• Allowed us to make some money and dispose

of our manure solids


Feedstock PreparationVery few materials instantly ready for large-scale vermicomposting

Manure separators – Ver 1.0 & 3.3

Compost Preparation

• All materials stored under cover and on concrete

• Materials are mixed with large agricultural equipment to a specific recipe (17 ton/batch)

• 8 loads of manure solids to 1 load of waste silage

The WORM POWER Story

Large-scale Vermicomposting • Bottom line:

• This system works• Allows us to make some money and dispose

of our manure solids• It is not the long-term manure

management-sustainability solution


Coyne Farms• Like to be innovators and listen to new ideas • Potential ideas are highly scrutinized

– Is it the right fit?– Is there a reasonable return on investment?– Is it the right thing to do?– Milk co-op formed

• 11 farms• Similar values &

management• Traceability important

moving forward– Big investment– Right fit– Right thing to do

Addressing Challenges• Urban pressures• Heavily traveled roads• Odor control• Image & public

perception

Currently• Drag line system is working• Incorporating precision ag technologies

– This has a huge upside and will allow our manure management program to get better

• We have 2,000 acres and 1,000 milk cows, which is a workable ratio

Looking to the Future• Continued adaptation of precision

farming technologies:• Starts at the corn planter• Grid mapping fields• Topographic maps• GPS technology tools• Variable rate manure application

– Green Seeker technology

• Real-time yield monitors• Accuracy & efficiency


Looking to the Future• Develop value-added relationships with

row crop farmers:– This needs to happen

• Evaluatingmanure digesters

Looking to the future• Keep an open mind with these goals:

– Meticulous nutrient management plan• Being as precise as you can, even if land acres

exceed cow pressures!

– Good stewardship– Plan your work and work your plan– Minimize odors– Transparency & honesty
