2015 Iowa Crop Progress Progress Review, December 2015

The Crop Progress and Condition Report is made possible by the dedication of our volunteer Crop Progress Reporters. A review of Iowa crop land with charts and graphs.

07017-006 Little Clear Lake Watershed Final Report

Little Clear Lake is a 162 acre natural lake located in the western part of Pocahontas County. The lake has a 375 acre watershed that is gently rolling with nearly 84% of the watershed in row crop production. The lake is listed on the Iowa DNR’s impaired waters list due to nutrients, siltation and exotic species (purple loosestrife). These impairments have been verified with in-lake monitoring and landowner conversations as well as watershed modeling. The watershed models estimates that the average sheet and rill erosion is 1.74 tons/acre/year and sediment delivery is .12 tons/acre/year with a total of 44 tons/year being delivered to Little Clear Lake. The goal of the Little Clear Lake Watershed Protection Plan is to (1) reduce sediment delivery to Little Clear Lake by 60%, or 26.5 tons annually, by installing best management practices within the watershed. Doing this will control nearly 100% of the of the lake’s drainage area; and (2) initiate an information and education campaign for residents within the Little Clear Lake watershed which will ultimately prepare the residents and landowners for future project implementation. In an effort to control sediment and nutrient loading the Little Clear Lake Watershed Protection Plan has included 3 sediment catch basin sites and 5 grade stabilization structures, which function to stabilize concentrated flow areas.

Row Crop Response to Topsoil Restored on Borrow Areas, HR-186, Supplemental Report, 1982

Borrow areas are created where soil is needed to provide fill for construction projects. This research evaluated (1) the changes in row crop productivity resulting from removal of soil for highway construction in Iowa and (2) restoration methods which included: depth of topsoil, subsoil tillage, manure application, and two years of legume growth prior to row cropping. The research was carried out from 1977-1981 at four locations. Corn and soybean y1elds from borrow areas have been below, equal to; and greater than yields from undisturbed, neighboring farmland. Little or no yield increase was noted from restored topsoil at coarse textured sites. At finer textured sites, a marked yield increase of both crops occurred after the addition of 6 inches of topsoil but little added yield increase resulted from restoring 12 inches of topsoil. Subsoil tillage has shown little or no beneficial effect on crop yields. The manure treatment has resulted in a corn yield increase but only in the first year after application.

Row Crop Response to Topsoil Restored on Borrow Areas, HR-186, 1982

Borrow areas are created where soil is needed to provide fill for construction projects. The changes in row-crop productivity resulting from removal of soil for highway construction in Iowa and restoration methods, which included addition to topsoil, subsoil tillage, manure application, and 2 yr of legume growth before row cropping, were evaluated. The research was carried out from 1977 to 1981 at four locations. Corn and soybean yields from borrow areas have been below, equal to, and greater than yields from undisturbed neighboring farmland. Little or no yield increase was noted from restored topsoil at coarse-textured sites. At finer-textured sites, a marked yield increase of both crops occurred after the addition of 6 in. of topsoil but little added yield increase resulted from restoring 12 in. of topsoil. Subsoil tillage has shown little or no beneficial effect on crop yields. The manure treatment has resulted in a corn yield increase but only in the first year after application.
