Summary

• Early results indicate very high P concentrations and yields in fall when leaves are not collected; spring can also be high

• Majority of P is in the dissolved phase as orthophosphate in fall, particulate in spring

• Leaf collection/sweeper timing could be crucial. Need more basin‐specific information to measure response

• Model simulations indicate annual P load from urban areas may be higher than originally thought but lower than agricultural sources.

CoverCropPilotProject• Heidi Johnson, Crop and Soils Educator, Dane County – UW‐Extension

Yahara Pride Cover Crop Demonstration Plot

Heidi JohnsonDane County UWEX Crops and Soils Agent

Goals of YP Demonstration Plot

• Evaluate many different cover crop species and planting dates– After silage harvest and manure application

• Options after wheat will be different• Ideal cover crops

– Erosion protection, reduce phosphorus run‐off– Economically beneficial for farmers

Cover Crop Demo Plot

• Goal is to show options for planting after silage – Field for demo was in alfalfa

• Alfalfa killed on the first of September• Manure applied• Half of plots were no‐till, half of plots were strip tilled

Cover crops• Winter Rye (100 lbs./acre)• Annual Ryegrass (var. King) (25 lbs./acre)• Oats (var. Badger) (60lbs./acre)• Barley (100lbs./acre)• Rye/Barley (60, 25 lbs./acre)• Tillage Radish™ and Rye (4, 100 lbs./acre)• Tillage Radish™ and Barley (4, 100 lbs./acre)• Tillage Radish™, Austrian Peas and Rye (4, 20 and 65 lbs./acre)

Planting dates

• September 9• September 23• September 30• October 10

Comparing the Cover Crops• Pictures taken of plots • Measurements

– Visual estimation of ground cover in plots – fall – Actual measure of residue cover ‐ spring– Height of cover crops – forage stick– Biomass – 2 square foot samples– Soil samples to 1 ft. – analyzed for nitrates

• Calculations – Soil loss estimates – using biomass– Phosphorus index– Seeds costs

Yield

• Plots that contained Winter Rye planted very early were slightly less yield but lacked consistency

• Annual ryegrass didn’t die easily, caused spring issues

• Both rye and ryegrass require an additional herbicide treatment and added cost

The Bottom Line• If cover crops can go in very early – get good growth on winter killed cover crops

• Rye and wheat are the only late options –spring growth– Provide a spring forage

• Farmers needs to plan on spending extra time in the spring managing overwintered cover crops

The Future

• Continued this fall in the same field• Planted cover crops at different planting rates• Two planting dates• Silage again

NEW WaterUpdate on Silver Creek Pilot Project

Bill Hafs - NEW Water 10/2014

NEW Water Background information 31,624 lbs Phosphorus (P) discharge peryear (Green Bay & De Pere Facilities) isless than 3% of total P entering Green Bayfrom Fox River (1.2 million lbs. P/ year).

9,332 lbs P reduction target required byTotal Maximum Daily Load (TMDL)Watershed Plan at NEW Water.

$223 – $394 million dollars estimated costfor additional treatment to reduce P totarget at NEW Water. ($23,896 - $42,220cost per pound).

9,332 lbs reduction target is less than 1%of P entering Green Bay every year fromthe Lower Fox River Basin.
