6. Soil Organic Matter Network, Arlington Plots Organic Matter, Wisconsin, USDA-ARS and University of Wisconsin [USDA.ARS.CPSWPRC.Arlington]
This experiment was established in 1958 and consists of a continuous corn system with various levels of nitrogen application. In the preceding 25 years, there was continuous corn with residue burning. ...


7. Broadbalk Wheat Experiment, Soil Organic Matter Network (SOMNET), U.K. [IACR.Broadbalk]
This experiment began in 1843. The site was possibly farmed since Roman times (i.e at least 1500 years). Map of 1623 shows field in arable use. 1839-1843 arable crops: turnips, barley, peas, wheat, ...


8. Nutrient Deficiency Experiment (DIV, Thyrow), SOMNET Long Term Soil Organic Matter Database [HUB.IFP.DIV]
This experiment began in 1937. The soil at the site is described as a Leptic Podzol (FAO). The experiment consists of the following land uses and treatments: Land use: 1937-1958 2 year rotation ...
