What are some benefits of manure?
A.
Transitional Period; Slower to dry out; Soil slower to warm; Specialized planting equipment; Nutrient Management Challenges; Increased Diseases; Pesticide Use; Cand Furrow Irrigate
B.
Typical costs $20-$40/acre; Nitrogen/grazing benefits can justify costs
C.
Weed suppression - growing/later seasons; Disease/insect pest cycles broken by adding biological time; Provides additional grazing for livestock
D.
Grazing removes soil quality benefits - partial/mob grazing strategy; Must be aware of herbicide carry-over impact on cover crop - herbicide restrictions on grazing; Ways to reduce seed costs
E.
1992 when ocean dumping was prohibited
F.
Sunflowers, Flax, Safflower, Buckwheat; Match to your goal
G.
Treatments to eliminate hazards; Restrictions on types of land/crops; No food crops
H.
plants grazed - secrets chemicals into soils = biology/aggregation
I.
Saves water; Reduces Erosion; Less Fuel/Labor Costs; Less equipment costs; Less field prep time; Increases soil quality; Carbon sequestration; Less dust, air pollution
J.
Provides long growth period potential: August to freeze or spring if winter species; Fall grazing opportunity
K.
Odor; Soluable Salts
L.
After Wheat Harvest; After corn/soybeans; Early spring prior to seeding summer crop
M.
Rolling spikes (Planter); Hydraulic Down pressure
N.
Leaching and runoff of nitrates and phosphates (nitrate leaching more of an issue in storage); Generation of gaseous air pollutants (Methane/Ammonia); Applying evenly
O.
horticultural and high value crops
P.
Legumes higher in protein; Grasses higher in tons of feed; Brassicas very good grazing
Q.
Pollutants; Human Pathogens; Human disease vectors; Pathogens; Others
R.
Crop planted between periods of regular crop production to: Positively benefit soil; Aid in pest control; Improve success of no-till productions; use as grazing resource (Integrating Livestock)
S.
Source of nutrients - slowly releases N, P, K; Adds organic matter - 20-40% organic solids in manure; soil microbial improvements
T.
crop grown just to protect the soil from erosion

aerobic decomposition of manure or other organic materials - generates temps up to 150 degrees;
incorrect
27.
Excellent nutrient cycling/residue decay; Tremendous roots; Frost hardy; Radish, Turnip, Rapeseed (non-food canola)
incorrect
28.
try to destroy them w/ heat and other treatments
incorrect
29.
Produce lots of dry matter; Good for grazing; High C:N ratios; Oats, Rye, Triticale, Millets, Sudangrasses
incorrect
30.
Challenge of short growth period before freeze: Longer periods after silage corn/seed corn; Possible arial seeding before harvest
