Conservation Programs Flashcards
How does conservation fare in the new Farm Bill?
conservation compliance added back to insurance
cuts of $4-5B per over 10 years (decreases acreage enrollment)
consolidation of programs
higher caps on contracts
fewer farms getting contracts
What is NRCS?
Natural Resources Conservation Service
a federal-state partnership
does the Web Soil Survey, National Resources Inventory and National Cartography & Geospatial Center
What did NRCS used to be called?
Soil Erosion Service
Soil Conservation Service
Soil Conservation District Act
How does NRCS operate at the state level?
prioritize areas and implement programs
state technical committees
What are the general categories of land use?
cropland, grassland pasture and range, forest-use land, special uses, miscellaneous land, urban land
special - federal and state parks, wildlife refuges, rural transit, public facilities, farmsteads, farm roads
What is land cover?
What the land looks like from the surface.
How has cropland use changed over time?
fewer acres in use, less idle cropland, less summer fallow and pasture
What four crops have dominated cropland use over the last 50 years?
corn, soybeans, hay, wheat
What is most conservation spending for?
land retirement and working lands programs
What is the historical context for land retirement?
initially concerned with controlling surplus production, shifted to primarily worried about controlling erosion in the 1980s
What did the 1936 Soil Conservation and Domestic Allotment Act do?
encouraged a shift to soil conserving crops
What did the 1956 Agricultural Act create?
the soil bank conservation reserve
When was CRP created?
1985 Farm Bill
Conservation Reserve Program - primary mechanism for moving land into retirement now
amended in 1990 and 1996
What is CRP concerned with?
removing highly erodible and marginal lands from production
not concerned with prime farmland
Why does USDA survey soils?
to understand the crop production resource base
through the soil series and soil mapping units
What is HEL?
highly erodible lands
defined in 1985 Farm Bill - land capability classes IV - VIII OR erosion excessively greater than T
defined by Federal Register - ratio of RUSLE:T
What is T?
the tolerable soil loss
What is the soil erosion index?
EI = (R*K*L*S)/T R = rainfall K = susceptibility factor L = slope length S = slope steepness
EI >= 8 is HEL
