Shrink-Smart Small Towns are those that have thriving quality of life despite depopulation since 1994.
This publication discusses how smartly shrinking towns differ from other declining places; and outlines recommendations for communities to maintain quality of life as their populations decline.
David J. Peters, Hannah Fisher, and Kimberly Zarecor
Small towns in the Midwest have experienced dramatic changes in social and economic conditions since the 1980s. In the Midwest, most small communities have experienced decline in terms of shrinking populations, exodus of younger people, job losses, and poorer community services (Kusmin 2016). One theoretical explanation for these changes is the shift away from an industrial economy to a postindustrial one, which has impacted traditional rural sectors like agriculture and manufacturing particularly hard (Peters 2013). There is clear evidence that these downward trends have persisted over the past several decades; and are unlikely to be reversed in most communities (Johnson & Lichter 2013).

The GeoTagged Photos To Points tool is available in ArcGIS Desktop Standard license. The tool located in the Data Management toolbox, allows you to visualize the locations of images taken with a GPS-enabled camera or mobile device (such as an iPhone). The tool creates points from the x-, y-, and z-coordinate information stored in Exif (Exchangeable image file format) metadata within the photo.
Site-Specific Nutrient Management: For Nutrient Management Planning To Improve Crop Production, Environmental Quality, and Economic Return
Agustin Pagani, John E. Sawyer, and Antonio Mallarino
Consistent use of nutrient management planning has been identified by USDA/NRCS as lacking on many farms in the USA (Conservation Effects Assessment Project (CEAP), Assessment of the Effects of Conservation Practices on Cultivated Cropland in the Upper Mississippi River Basin). It has also been shown that all resource concerns are rarely achieved with a single conservation practice. Implementation of site specific nutrient management planning to minimize nutrient loss, conservation practices to control runoff, and practices to trap materials leaving the field should be utilized as a combination of efforts. In combination, these practices have the ability to reduce agricultural non-point source pollution and to enhance economically sustainable crop production. However, increased nutrient management practice implementation requires increased producer awareness and well informed crop advisers.
Managing smoke produced by prescribed fires has, in recent years, become a critical consideration when planning a prescribed fire event. In some situations, planning for smoke management may be more complicated than planning for the prescribed fire itself. Considerations such as human and animal health and safety, air pollution, and reduced visibilities must be taken into careful account when planning even a small, routine prescribed burn.

Nitrogen (N) is an essential nutrient for animals and plants. For cereal crops, it is often the most limiting nutrient and therefore important in regard to fertilization and management. Nitrogen is abundant in nature; air is 78% N; rocks of the earth’s crust have 50 times more N than the atmosphere; and the surface layer of most cultivated soils contains 1,200 to 6,000 lb N/acre, with more than 90% in organic forms. However, the majority of this N is not in a form that plants can take up, and must be converted to plant available ammonium (NH4) or nitrate (NO3), or supplied from atmospheric N2 fixation by plant/microbe symbiosis or industrial fertilizer manufacture. Nitrogen is very reactive in that it can change among many forms: organic like amino acids, proteins, and chlorophyll; gasses like ammonia (NH3), dinitrogen (N2), and nitrous oxide (N2O); and ions like NH4 +, nitrite (NO2 -), and NO3 -. Conversion from one form to another occurs by many chemical and biological processes, which are highly influenced by environmental conditions, especially temperature and moisture. The overall interaction between soil, air, microbes, plants, animals, and humans is called the N cycle (see figure). In soils, plants and microbes interact with all components of the cycle, with many processes occurring simultaneously and all having potential influence on the fate of N. A major factor complicating N management for crop production, and the importance of climate, is that the soil is an open system – meaning than N can move out of the soil (“be lost”) to the atmosphere or to ground and surface waters. If such movement did not occur, then N management would be much less complicated. Research continues to better understand the intricacies of the soil N cycle and the influence from climate, with the goal to provide management options in order to enhance N use by crops and therefore improve agronomic efficiency, economic profitability, and environmental quality.

Since 2000, soybean aphid has been the primary soybean pest in the north-central region of the United States. Although infestation can be sporadic and unpredictable, this aphid has demonstrated the capacity to cause significant yield loss if not managed properly. This regional field guide reviews current knowledge about the biology and management of soybean aphid and offers recommendations for profitable decision making in soybean.

Soybean cyst nematode is the most economically significant pest of soybeans in Iowa and has been found in 98 of the 99 Iowa counties. Infested soybean plants often show no symptoms other than reduced yield. The 62-page field guide is designed as a resource for agronomists and farmers to manage soybean cyst nematode.
Gregory L. Tylka and Mark P. Mullaney
Soybean cyst nematode (SCN) is widespread in Iowa. The nematode reproduces quickly (completes several life cycles or generations per season), survives in the soil for 10 years or more in the absence of a soybean crop, and can cause substantial yield losses, particularly in dry years.

Soybean gall midge was first noted in northeastern Nebraska in 2011 and eastern South Dakota in 2015. Midge infestations were isolated and spread slowly, before eventually being detected in Minnesota and northwestern Iowa in subsequent growing seasons.

Measuring water chemistry prior to feeding will help the farmer gauge the likelihood that fish are stressed. Sick and stressed fish will not eat feed and should not be fed in order to avoid water quality issues and mortality. Visually inspecting fish for external signs of disease such as lesions, discolored skin, and erratic swimming behavior should be done to prevent feeding stressed fish. If the water quality falls within the optimal range and fish appear to be disease free, the farmer should begin feeding by hand a small portion (handful) of the feed that the fish have been rationed.
