The sustainability of the agricultural sector worldwide is increasingly being pressurized by ecological, economic, and social developments. The Dutch government is promoting enhancing circular agriculture as an important rural development strategy in response to the challenges the sector is facing. All farmers in the country will have to be involved in closed cycles by 2030, but many farmers do not want to or cannot make this transition. This study aims to identify the different factors that influence a farmer’s decision to transition towards circular agriculture. Based on thirteen semi-structured interviews with already transitioned farmers, a policy officer, a consultant, and …

The Value Of Soil Sampling And Sampling Density: Conceptual Framework (Part 1), Taro Mieno, David Bullock

Cornhusker Economics

When considering variable-rate nitrogen or seed application, soil sampling can provide farmers and their consultants with valuable information about the spatial distributions of soil properties such as organic matter, micro- and macro-nutrients, and pH. Conceptually, that information may be especially valuable for site-specific input management. But just as farmers make decisions about input applications, they also must make decisions about soil sampling, and in particular, must choose soil sampling density. It is standard practice for U.S. corn and soybean farmers to take soil samples on their fields every three or four years at a density of one sample per 2.5 …

Chemistry & Biochemistry Faculty Publications

Labile organic carbon (LOC) fractions and related enzyme activities in soils are considered to be early and sensitive indicators of soil quality changes. We investigated the influences of fertilization and residue incorporation on LOC fractions, enzyme activities, and the carbon pool management index (CPMI) in a 10-year field experiment. The experiment was composed of three treatments: (1) no fertilization (control), (2) chemical fertilizer application alone (F), and (3) chemical fertilizer application combined with incorporation of wheat straw residues (F + R). Generally, the F + R treatment led to the highest concentrations of the LOC fractions. Compared to the control …
