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: Crop rotation is the practice of growing a series of different types of crops in the same area in sequential seasons. Crop rotation gives various nutrients to the soil. A traditional element of crop rotation is the replenishment of nitrogen through the use of green manure in sequence with cereals and other crops. Crop rotation also mitigates the build-up of pathogens and pests that often occurs when one species is continuously cropped, and can also improve soil structure and fertility by alternating deep-rooted and shallow-rooted plants. Crop rotation has increased in the south in the last 10 years due to the changing tides of the ever changing grain price. With the increase in corn acres across the south, as well as the increase in irrigation, we have seen a steady increase in yields. There are many studies showing yield increases of 10 to 15 percent in soybeans and corn when rotation is utilized. Rotations also help with a reduction in nematodes, weeds and diseases. Northern Leaf Blight is a good example of a disease that has increased over the last several years, and can be reduced by rotating corn and soybeans. Understanding the relationship between nitrogen (N) and crop rotation is very important when making N management decisions. There are several benefits to using crop rotation, including improved nutrient cycling, soil tilth, and soil physical properties; and enhanced weed control. Crop rotation also may influence the rate of N mineralization or the conversion of organic N to mineral N by modifying soil moisture, soil temperature, pH, plant residue, and tillage practices.The incremental increase in N use over the past five decades, due to emphasis on maximizing yield, has led to a subsequent increase in N in the soil profile of some agricultural fields. Therefore, the influence of agricultural practices on water quality has prompted studies to develop best management practices to optimize the use of fertilizer N and reduce N loss to surface and groundwater. Crop rotation can play a major role in minimizing the potential risk of nitrate leaching to surface and groundwater by enhancing soil N availability, reducing the amount of N fertilizer applied, and minimizing the potential risk of N leaching. Research on the impact of long-term crop rotation on soil N availability shows that planting alfalfa, corn, oat, and soybean significantly increased the mineralized net N in soil compared with planting continuous corn. Because soil N mineralization can effect yield, crop rotation thus can be used as a management system to enhance the soil nutrient pool, thereby reducing the fertilizer N input and minimizing the risk of leaching of excess N during wet weather. A combination of conservation tillage practices and crop rotation has been shown to be very effective in improving soil physical properties. Long-term studies in the Midwest indicate that corn-soybean rotation improves yield potential of no-till compared with continuous corn. The reduction in yield of continuous corn in no-till is attributed to low soil temperature during seed germination, which is evident on poorly drained soils under no-till. Studies show that the poor performance of no-till corn following corn is more likely due to the previous crop than to surface residue conditions preventing early-season warming and drying of soils. The use of a legume cover in crop rotation can provide a substantial amount of N to a succeeding crop. Research has indicated that seeding rates for legumes can be reduced by approximately one-third of that recommended for forage production when used as cover crops without sacrificing biomass or N accumulation. Also, the type of crop grown in the previous year can impact the efficiency of conservation tillage, especially for no-till systems, due to the kind and amount of crop residue from the previous crop.
Book Synopsis Intercropping Corn and Soybean by : Raeann L. Huffman
Download or read book Intercropping Corn and Soybean written by Raeann L. Huffman and published by . This book was released on 2021 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intercropping is the practice of growing multiple crops together in the same field. This is not commonly implemented in Midwest agriculture - instead, current monoculture practices have garnered attention because of the negative environmental impacts of monoculture farming. For this study, corn and soybean were intercropped in a production agriculture setting to investigate the benefits to the producer and the environment. Intercropping corn and soybean crops may reduce the need for added nitrogen (N) fertilizer, saving money on inputs and potential loss of N from the farm to the environment. Soybeans within the system may utilize less of the soil N leaving more N, available for the corn crops. Soybean plants are legumes and form a symbiotic relationship with bacteria the soil, Bradyrhizobium japonicum, which allows the soybean plant to fix plant-unavailable N into a plant-available form. Therefore, corn plants within the intercropping system would require little, if any, synthetic N fertilizers.An intercropping system may decrease the loss of N associated with greenhouse gases and acid rain components. The loss of N through leaching and denitrification are seen in monoculture practices where N fertilizer is used. The cause of the negative environmental impacts is from the over application of nutrients that are lost from the soil profile. The macronutrients which crops require in large amounts include nitrogen (N), phosphorous (P), and potassium (K). N, P, and K are being lost in large amounts increasing the creation of laws in many areas, like the Chesapeake Bay and the Lake Eerie watershed, are limiting how much and when fertilization can occur. The proposed intercropping system could increase farmer profit without any additional N fertilizer applied.This study compares monoculture and intercropped systems of corn and soybean. All plots are treated the same for fertility in that no supplemental macronutrients were applied. The monoculture treatments were 38-cm corn (narrow-row corn), 38-cm soybean (narrow-row soybean), 76-cm corn (wide-row corn), and 76-cm soybean (wide-row soybean). Populations were constant for the monocropping treatments: 83,980 corn plants ha-1 (34,000 plants ac-1) and 345,000 soybean plants ha-1 (140,000 plants ac-1). These four monoculture treatments were compared to two intercropping treatments, intercropped corn and soybean with a corn population of 27,993 plants ha-1 (11,333 plants ac-1) and intercropped corn and soybean with a corn population of 55,985 plants ha-1 (22,666 plants ac-1). Since producers are constantly manipulating different cropping systems, this study took into consideration differences in the effect of row orientation and row spacing on yield. Thus, this study compares current monoculture production to intercropping to determine if intercropping could be profitable while requiring fewer environmentally-insensitive inputs.Throughout the study, various statistical analyses were conducted to evaluate if there were any differences between the six treatments. Results evaluating the impact of row orientation and row spacing on corn and soybean production showed that both row orientation and row spacing did not significantly influence corn and soybean productivity. Comparing corn leaf tissue, corn intercropped with soybean contained a significantly greater N concentration within the plant tissue than monoculture corn (p = 0.0006). This difference was visually observed during the 2020 growing season. Further, the results showed that intercropped corn and soybean produced a greater weight of seed per plant than any of the monoculture treatments. Profitability of the monoculture and intercropped treatments was further evaluated to compare the two cropping systems. Two different analyses were conducted, comparing the different prices of corn and soybean at a set market price, and then comparing the different treatments at a range of potential prices. On 19 October 2020 the grain was sold at Prairie Central Co-operative in Lexington, IL. The price received for soybean was $10.24 bu-1 , and corn was $3.79 bu-1 . The intercropping profit was significantly greater than all the monoculture treatments. Since grain prices vary significantly from year to year, different ranges of prices were further evaluated using historical prices from the past 10 years. This resulted in a price range of $3.00 to $6.00 for corn prices and $8.00 to $14.00 for soybean prices. Different price combinations were evaluated and showed that the intercropping treatment was more profitable than the monoculture treatments at most combinations of corn and soybean prices. Further, the profitability of intercropping compared favorably to traditional monocrop corn grown in the Midwest using N fertilizer. Results of this study show that intercropped corn and soybean may be more profitable and benefit the environment from reduced inputs of N fertilizer.

Book Synopsis Corn and Soybean Genotypes with Contrasting Root System by : Alexandre Tonon Rosa
Download or read book Corn and Soybean Genotypes with Contrasting Root System written by Alexandre Tonon Rosa and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of tillage on crop yield, early growth, and soil nutrient stratification can be influenced by fertilizer placement. In addition, deeper root systems can enhance the crop ability to uptake water and nutrients. A thorough understanding of how these factors interact can result in increased grain yields and profitability for the producer. Three studies were completed to describe and evaluate different aspects of crop root system and response to fertilizer placement and tillage. The objective of the first study was to characterize the root system of two genotypes of corn (Zea mays) and soybean (Glycine max (L.) Merr.) using image analysis in the greenhouse and in the field, as well as evaluate dry weight accumulation and nutrient uptake patterns by shoot and root plant parts for both crops. Two different genotypes of each crop were sampled during the growing season to access root characteristics such as biomass, length, surface area, average diameter and volume. Significant differences were found in corn where the P1151 AM hybrid had greater root length, surface area and volume than the P1105 AM hybrid. In soybean, the differences were found in nutrient uptake with overall greater nutrient uptake values for the poor drainage variety (PD) compared to the good drainage variety (GD). The objective of the second study was to evaluate the effect of fertilizer placement and tillage system on corn with different genotypes. Three fertilizer treatments were combined with two different corn genotypes selected based on contrasting root systems and two different tillage systems. The three fertilizer placements were sub-surface band, broadcast, and control. The two hybrids of corn used were a P1151 AM hybrid and P1105 AM hybrid. The two tillage systems were no-till (NT) and strip-till (ST). Corn hybrids showed different response in root biomass but did not show a consistent response in other characteristics evaluated. Broadcast and sub-surface band increased nutrient uptake and grain yields over the control but were not significantly different from each other. Tillage showed no difference in corn response. The objective of the third study was to evaluate the effect of fertilizer placement and tillage system on contrasting soybean genotypes. Three fertilizer treatments were combined with two different genotypes selected based on contrasting root systems and two different tillage operations. The three fertilizer placements were sub-surface band, broadcast, and control. The two varieties of soybean used were one recommended for poor drainage (PD) and one recommended for good drainage (GD). The two tillage operations were NT and ST. Soybean root biomass differences were observed by varieties. Sub-surface band treatment favored early soybean growth, biomass and P uptake at the V3 growth stage, but it did not turn into yield increase. Soybean grain yields did not respond to fertilization in this study. Yield was affected significantly by variety selection and response varies by site-year.
