Conservation tillage is gaining popularity throughout the country. This relatively new practice saves fuel, reduces erosion, and cuts field work. The Lyon County, Kentucky, field pictured is shown immediately after a four inch rain. Little erosion damage is evident.
This is a cropland field in Henry County, Alabama, where erosion and resulting sedimentation occurred due to farming up and down the slope with no conservation measures applied. In 1977, sheet and rill erosion on cropland alone totaled almost 2 billion tons. Half of this total was excess erosion -- that
which occurred at rates above those that soils can tolerate without affecting their long-term productive potential.
This shows a seeded wheat field in the Palouse of Washington State that lost 200 tons of soil per acre during one rain storm.
Nowhere in the Nation has soil and sediment erosion been greater over time than
Precise amounts of water can be applied with assurance that the total field will receive adequate and uniform amounts. Good land use planning balances land use requirements with land capability. This Pennsylvania community is compact and well defined, surrounded by agriculture that is free of urban sprawl, with steep slopes in trees and level or gently sloping acres in cropland.
