This book was released on 2004 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although tillage systems produce different soil conditions, which result in different ideal planting dates, and crops respond to planting date, most of tillage research is conducted based on a calendar date. If a tillage system by planting date interaction exists, most of the planting date recommendations based on calendar date research could change. Different authors have modified surface residue distribution in an attempt to achieve optimal soil conditions for crop growth in the row zone while maintaining optimum soil conservation conditions in the mulched interrow zone. A reasonable goal for soil management involves identifying the level of soil and residue disturbance necessary to optimize soil environmental conditions for the corn plant and residue cover for soil conservation. In order to design a tillage system that produces a residue-free band-width based on site-specific soil properties and crop needs, the use of a model to capture the effect of surface residue management, soil non-uniformities (i.e., row zone tillage), and tillage is necessary. Considering a potential tillage by planting date interaction and site-specific strip tillage opportunities, this thesis has the following objectives. The first objective is to test the performance of strip tillage, no tillage, and conventional tillage when each system is planted on the day that optimum soil temperature and water conditions for planting are reached for each system. The second objective is to conduct a soil temperature sensitivity analysis to residue-free band-width, and tillage depth with strip tillage using a model that couples water and heat transport in non-uniform soils. In a two-year study on a poorly drained soil tillage system, effects on corn yield were not detected when preestablished soil temperature and water content criteria were used to determine the day of planting each system. On the other hand, planting date has an effect on corn yield. A tillage system by planting date interaction was detected for soybean yield in one of two years, when drought conditions existed during the second half of July and August. Soil temperature, soil water content, and matric potential were most sensitive to changes in residue-free band-width at 0.05-m in both soils studied.

Available in PDF, EPUB and Kindle. Book excerpt: Conservation tillage systems and rotations with corn (Zea mays (L.) increases surface residue and make popular choices for erosion control in soybean (Glycine max (L.) production. Tillage and system (rotation) affect levels of residue input which in turn affect the response of the soil and plants. Few studies have looked at the long term (23 years) effects of management practices on soil and soybean physiology. The objectives of this study were to (i) determine the effects of surface residue on soil temperature throughout the growing season, (ii) determine the effect of amount of residue on SOC, and (iii) determine the physiological response of soybean to residue, system and tillage treatments. Rotation and NT increased surface residue and soil organic carbon (SOC) for the top 0-5 cm of soil in both years of data collection. Continuous soybean and tillage increased maximum soil temperatures but did not affect minimum temperatures over the course of the study. The differences in plant height and canopy coverage were limited and not directly related to changes in soil temperatures. Long term decisions in tillage and system have a direct effect on soil response but the physiological response of soybean isn’t fully understood.

This book was released on 2018 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corn (Zea mays L.) and soybean ( Glycine max L.) production in the Midwest US can result in significant nutrient leaching to groundwater and surface waters, which contributes to eutrophication and hypoxia in the Gulf of Mexico. A promising strategy to control nutrient leaching and sediment runoff loss during winter fallow period is the use of cover crops (CCs). In southern Illinois, CCs are not widely adopted by farmers due to economic constraints and the lack of scientific data that supports benefits of incorporating CCs into the corn-soybean rotation. This doctoral dissertation addresses the critical question of the feasibility of the use of CCs in southern Illinois and is divided into three overarching research studies with different objectives divided into six research chapters. Research study 1 was a field experiment conducted from 2013 to 2017 to examine the effect of CCs (CC vs noCC) under two tillage systems [(no-tillage (NT) and conventional tillage (CT)] on aboveground plant attributes [dry matter yield, C:N ratio and nitrogen uptake (N uptake)], crop yields, available soil N content and N leaching in the vadose zone. The experimental layout was a randomized design with three rotations including corn-noCC-soybean-noCC [CncSnc], corn-cereal rye (Secale cereale L.) -soybean-hairy vetch (Vicia villosa R.) [CcrShv], and corn-cereal rye-soybean-oats+radish (Avena sativa L. + Raphanus sativus L.) [CcrSor] and two tillage systems. Soil samples collected after corn or soybean harvest and CC termination were analyzed for standard soil fertility parameters. Pan lysimeters installed below the 'A' horizon with depth varying from 22 to 30 cm were used for measuring soil solution nutrient concentration on weekly or biweekly basis depending on the precipitation. In NT system, the corn yield was 14% greater with CcrShv compared to CncSnc, whereas no significant difference existed in corn yield due to CC treatments within CT. Both CC treatments under NT reduced soybean yield by 24 to 27% compared to noCC. The rotations CcrShv and CcrSor with hairy vetch and oats+radish as preceding CCs resulted in 89% (37.73 vs 19.96 kg ha-1) and 68% (33.46 vs 19.96 kg ha-1) more nitrate-N (NO 3-N) leaching than the CncSnc during cash crop season 2015. During the CC season in spring 2016, cereal rye CC in CcrShv and CcrSor reduced the NO 3-N leaching by 84% (0.68 kg ha-1) and 78% (0.63 kg ha-1) compared to the CncSnc, respectively, under the CT system. Overall, our results indicated that the CT system had greater N leaching losses compared to NT system due to higher N availability in the tilled soil profile. The goal of the second research study was to understand the mechanisms of N cycling by CCs. We applied 15N labeled urea fertilizer (9.2% atom) to corn that followed hairy vetch and noCC in May 2017 to evaluate the contribution of fertilizer and soil organic matter to N leaching and quantify the 15N content of surface runoff after storm events. During the 2017 corn season, repeated soil samples were collected and analyzed for 15N fertilizer recovery in soil at three depths. 15N recovery was higher in the corn that had hairy vetch as the preceding CC than the corn that had noCC by 13.13 and 3.68 kg ha-1 on soil sampling events of 7 and 21 days after planting of corn, respectively, at the depth 15-30 cm. Overall, the cumulative loss of 15NO 3-N during corn season 2017 was

Available in PDF, EPUB and Kindle. Book excerpt: This book compiles information relevant to understanding soybean production processes and condenses it into a single volume. The authors identify production practices and bring together diverse information that suggests ways for producers to better utilize the soil and climatic resources of the midsouthern U.S. to enhance production of this valuable and versatile crop. This publication makes a special effort to focus on information that will enhance soybean production in the midsouth, where yields have been lower than those in the upper midwester n portion of the U.S., however, much of the information, such as statistics and crop models, will be applicable to other regions, from Texas to the Carolinas.
