- ... Research was initiated to study the interaction between soil amendments (lime, gypsum, and ferrous sulfate) and dissolved molybdate reactive phosphorus [RP ] losses from manure applications from concentrated runoff flow through a sod surface. Four run-over boxes (2.2-m surface area) were prepared for each treatment with a bermudagrass [ (L.) Pers.] sod surface (using sod blocks) and composted dair ...

- ... There is growing interest in evaluating the effects of corn silage harvesting methods on erosion control. Increasing the silage cutting height will increase residue cover and could conceivably minimize off-site migration of sediments compared with conventional silage harvesting. The effects of residue level and manure application timing on runoff and sediment losses from no-till corn were examined ...
