Iowa farmers discuss how they leave their land a little better than they found it.
No-till / strip-till
Description
Tillage practices affect soil erosion and runoff, which is the primary source of phosphorous loss in Iowa. Using conservation tillage, 30% or more of the soil surface is covered with crop residue after planting. Using no-till, 70% or more of the soil surface is covered with crop residue after planting, which reduces soil erosion and surface runoff.
Benefits
Tillage effects on P loss are site specific. On average, there’s a 90% reduction in P load on no-till ground compared to chisel plowing, and a 33% reduction in P load on ground that had been chisel plowed, compared to moldboard plowed.
