Aerial ap: Next generation of cover crop seeding
By Christina Curell Michigan State University Extension
September 10, 2012 – Cover crops are fast becoming a common practice for many farms. According to a survey the Howard G. Buffett Foundation and the Conservation Technology Information Center (CTIC) sent to subscribers of Corn and Soybean Digest, 63.7 per cent of respondents said they did not have enough time to get cover crop established with harvest challenges. A solution to this dilemma is to apply cover crops before crops are harvested. One of the ways to do this is aerial seeding.
Aerial application is an economical way that farmers can apply cover crops to fields. Cost of aerial application is around $15 to $20 an acre plus seed costs. This may seem costly to farmers but when labour, time, equipment and fuel is added together along with the option to use more cover crop species, the cost is comparable.
A challenge to aerial application is proper seeding time prior to crop harvest. Michigan State University Extension – in cooperation with the Michigan Soybean Promotion Committee, the Corn Marketing Program and Al’s Aerial Spraying, LLC – has established two soybean and two corn demonstration plots on two farms. Four cover crop species: annual ryegrass, cereal rye, oilseed radish plus oats mix and annual ryegrass plus crimson clover mix were planted on four different days with the final application during the demonstration. Cover crop seed counts were taken to measure how many seeds made it through the canopy and reached the soil.
A demonstration of aerial application as well as plot tours will be held on Sept. 13, 2012 at Phillips Orchards & Cider Mill 1174 W. Gratiot County Line Rd. St. Johns, MI. Registration will start at 9 a.m. A hog roast luncheon will be provided.
