- Reducing soil disturbance may limit erosion, but many still consider tillage essential for seedbed preparation, particularly on poorly drained soils. Our objective was to quantify tillage and fertilizer management effects after 45 yr {21 in continuous corn [Zea mays L.] [CC] and 24 in corn–soybean [Glycine max (L.) Merr.] [CS] rotation} on a somewhat poorly drained silt loam near Belleville, IL. Four tillage (moldboard plow [MP], chisel tillage [ChT], alternate tillage [AT], and no-till [NT]) and five fertilizer (no fertilization, N-only, N+NPK starter, NPK+NPK starter, and NPK broadcast) treatments were evaluated. With N, P, and K fertilizer, yields were similar for tilled and NT treatments, averaging 8.73 Mg ha–1 for CC and 11.93 Mg ha–1 and 3.70 Mg ha–1 for rotated corn and soybean. Below recommended soil-test values resulted in NT yielding less than tilled treatments even though soil test P, K, and pH were similar. No-till with N, P, and K increased soil organic matter (OM) to 27.6 g kg–1 (20.5 g kg–1 in all other treatments), with the greatest increase from 0- to 5-cm. No-till treatments showed stratification of P and K, but it had no effect on yield. No excessive pH stratification was observed. Overall, fertilizer management predominantly influenced crop yield and with complete NPK management non-tilled yields were similar to tilled, even on flat, somewhat-poorly drained soils. No-till with NPK management therefore may allow farmers to maintain high yields while reducing soil and nutrient losses.
- Tillage x Fertility Crop Yields 1970-2015, Soils, and Plant TissueThese data represent crop yield data from 1970 to 2015 for the long-term Tillage x Fertility trial started by Dr. George Kapusta at the Southern Illinois University Belleville Research Center in Belleville, IL. Some other agronomic data are also included.BRC_TxF_yield_1970-2015.csvTxF soils increment data 1990 and 2013These data were used for the Cook and Trlica 2016 publication. Soil plow layer (0-15 cm) was constructed from 5-cm increments. Metadata is included with the yield README file.BRC_TxF_soils_increments_1990_2013.csvTxF Corn plant tissue 1990 and 2014These data were analyzed for the Cook and Trlica 2016 publication. Metadata are found in the yield README file.BRC_TxF_Plant_tissue_1990_2014 Corn.csvTxF historic soils composites 1978 1983 1990 1999 2011 2013These data were NOT included in the Cook and Trlica 2016 publication. Curation for the historic soils data was imperfect and any use of this data should be considered not completely reliable. A thorough explanation of data processing and data issues is included in the README file. The composite samples were for the most part collected and analyzed at 0-15 cm soil cores.BRC_TxF_soils_composite_78 83 90 99 2011 2013.csv
