Book Synopsis Agronomic, Economic, and Ecological Response of Corn and Soybean Production Systems to Winter Cover Cropping and Minimum Tillage Management in the Mississippi Alluvial Valley by : Thomas Beauregard Badon
Download or read book Agronomic, Economic, and Ecological Response of Corn and Soybean Production Systems to Winter Cover Cropping and Minimum Tillage Management in the Mississippi Alluvial Valley written by Thomas Beauregard Badon and published by . This book was released on 2020 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winter fallow corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] production systems are susceptible to erosion and agrochemical transport. This research determined the effects of Cover Crop Minimum Tillage (CCMT) on erosion and agrochemical transport from corn-soybean rotations at field scale, while assessing impacts to agroeconomics and irrigation in Mississippi’s Delta Region. CCMT did not affect total suspended solids (p = 0.53), total inorganic phosphorus (TIP) (p = 0.30), or total nitrogen (TN) (p = 0.25) loads, but did reduce TIP (p = 0.018), TN (p = 0.011), and nitrate-nitrite (p = 0.007) concentrations. An economic loss of $281/ha with no effect on yield (p = 0.09), irrigation use efficiency (p = 0.38), or consumptive water use (p = 0.83) was observed. CCMT will not improve profitability of corn-soybean rotations in the Delta and transitioning from fallowing to CCMT will have varying effects on erosion and agrochemical transport.
Book Synopsis Impact of Winter Cover Crops and Nitrogen Recommendations for a Corn-soybean Rotation in Northeast Arkansas by : Brayden William Burns
Download or read book Impact of Winter Cover Crops and Nitrogen Recommendations for a Corn-soybean Rotation in Northeast Arkansas written by Brayden William Burns and published by . This book was released on 2020 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research plots were established on production farms in no-tillage, corn-soybean rotations following a winter cover crop. Yield optimum nitrogen rates (69.7 to 214.1 kg N ha−1) were consistently less than the University of Arkansas' recommendation of 247 kg N ha−1. Dynamic N-recommendation systems like N-Star, and measures of pre-sidedress available nitrogen reduced recommended N-application rate with little risk of insufficent N-supply. The Soil Health Tool recommended greater N-reductions but had a greater risk of N-insufficiency. In addition to soil N-tests, remote sensing indices proved to be useful nitrogen management tools. During the V8 growth stage, regressions of corn grain yield by index value produced R2 values of 0.84, 0.89, and 0.89 for Red-Edge Normalized Difference Vegetation Index, Chlorophyll Index Green, and the Green Normalized Vegetation Index, respectively. Through dynamic recommendation systems and remote sensing, nitrogen use efficiency in conservation systems may be improved without compromising agronomic or economic goals.
Book Synopsis Cover Crops and Irrigation Impacts on Corn and Soybean Production in the Mid-Southern USA by : Dillon Aaron Russell
Download or read book Cover Crops and Irrigation Impacts on Corn and Soybean Production in the Mid-Southern USA written by Dillon Aaron Russell and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reducing groundwater withdrawals from the Mississippi River Valley Alluvial Aquifer is imperative to sustain future irrigated cropping systems in the mid-southern USA. This research was conducted to determine the impacts of cover crops and irrigation sensor thresholds on corn (Zea mays L.) and soybean (Glycine max L.) production, water productivity, irrigation water use efficiency, and soil physical properties in the Mississippi Delta. The cover crop treatments included cereal rye (Secale cereale L.), hairy vetch (Vicia villosa R.), wheat (Triticum aestivum L.)-radish (Raphanus sativus L.)-turnip (Brassica rapa L.) mix, and no cover crop. The irrigation thresholds included -40 kPa, -90 kPa, and no irrigation. In 2020, cover crops and irrigation thresholds showed minimal impacts on most of the measured parameters but showed improvements as the study progressed. After two years, it was determined that long-term evaluations are needed to make a recommendation to producers in the mid-southern USA.

Download or read book Returns to Corn and Soybean Tillage Practices written by Michael Duffy and published by . This book was released on 1984 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extract: Average per-acre returns differ little for most U.S. corn and soybean farmers using various alternative tillage strategies, according to this analysis of 1980 farm-level production data. Midwest conventional-till soybean farmers, however, accrue a significantly higher average return than do Midwest no-till farmers. Most conservation-till soybean farmers in the three major producing regions incur significantly lower input costs than do conventional-till soybean farmers, but also harvest lower yields except in the Southeast. Significant differences were found in the use of specific corn and soybean inputs among alternative tillage strategies.
Book Synopsis Effect of Cover Crops, Grazing and Tillage Practices on Soil Microbial Community Composition, Function, and Soil Health in East Central Mississippi Soybean Production System by : Namita Sinha

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrating crop and livestock is being considered to improve soil health by carbon sequestration. A two-year study (2019-2021) at CPBES in Newton, MS was aimed to evaluate soil microbial diversity in the warm, humid regions, specifically southeastern USA. Amplicons targeting bacterial 16S rRNA genes and fungal ITS2 regions were sequenced. Taxonomic assignment and microbial diversity characterization were performed using QIIME2®. Soil fungal diversity showed significant differences (alpha diversity, p = 0.031 in yr. 2020 and beta diversity, p = 0.037 in yr. 2021). Canonical Correspondence Analysis (CCA) and Mantel test showed significant influence on fungal diversity due to carbon (rm = 0.2581, p = 0.022), nitrogen (rm = 0.2921, p = 0.0165) in yr. 2021, and on bacterial diversity due to EE-GRSP (rm = 0.22, p = 0.02) in yr. 2020. Long term study of ICLS can help us better understand the shift in microbiome to improve crop production sustainably.
Book Synopsis Short-term Effects of Winter Cover Crops on Soil Properties, Yield, and Partial Returns in a No-tillage Soybean Rotation by : Drew Dillion Kirkpatrick
Download or read book Short-term Effects of Winter Cover Crops on Soil Properties, Yield, and Partial Returns in a No-tillage Soybean Rotation written by Drew Dillion Kirkpatrick and published by . This book was released on 2021 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cover crops have the potential to provide many benefits including weed suppression, erosion control, and improvements to soil quality. These benefits can be affected by species, biomass accumulation, and management practices. Although large amounts of biomass are good for maximizing benefits, it can result in problems for establishing the subsequent crop. Soybean [Glycine max (L.) Merr.] accounts for over 50% of Arkansas crop hectares annually; therefore, understanding the effect that a cover crop can have on the following soybean crop is crucial to the successful implementation of cover crops within the state. A study was established to evaluate winter cover crops as an alternative to traditional Arkansas practices, such as winter fallow, as well as winter wheat (Triticum aestivum L.) soybean double-crop system, and the effect each cropping system has on soybean yield and partial returns. Additionally, a goal of this study was to assess a variety of cover crop species and blends as well as their effect on aboveground biomass accumulation, nutrient uptake, and stand establishment of the following soybean crop. Soil organic matter (SOM) and pH were also used to evaluate overall soil health following three full rotations of each winter treatment. Results of the study show that winter cover crops do not affect the following soybean crop establishment, but had a positive influence on soybean yield and partial returns in a no-tillage system. Except for blue lupin (Lupinus angustifolius), each cover crop treatment proved to be an equally viable alternative to a traditional double-crop system and more profitable than a winter fallow system. Cover crops not only have an immediate impact of increasing soybean yield, but cover crops also have the potential to provide long-term benefits. Previous research has shown that increased biomass production typically increases SOM and results of this study indicate that cover crop treatments produced up to four times as much aboveground biomass compared to a winter fallow management strategy. Treatments that produced the most biomass also accumulated the most aboveground nutrient contents for the macronutrients nitrogen (N), phosphorus (P), and potassium (K). There were no differences in soil health calculations, but each treatment received a "good" soil health score. Our results indicate that winter cover crops provide a promising alternative to the winter wheat soybean double-crop system and winter fallow management program and with continuous management, soil quality can be improved.
Book Synopsis Integration of Cover Crops Into Midwest Corn-soybean Cropping Systems and Potential for Weed Suppression by : Joshua S. Wehrbein
Download or read book Integration of Cover Crops Into Midwest Corn-soybean Cropping Systems and Potential for Weed Suppression written by Joshua S. Wehrbein and published by . This book was released on 2019 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cover crops have potential to provide benefits to agricultural systems, such as improved soil productivity, nutrient scavenging, weed suppression, and livestock forage. There are several challenges associated with cover crop integration into traditional Midwest corn-soybean cropping systems. One of these challenges is timely establishment in the fall, which is limited by the relatively late harvest of corn and soybean. Cover crop effectiveness is related to the amount of biomass produced, thus maximizing the growth period in the fall is desired. To address this challenge, we evaluated the potential to utilize early-season soybean maturity groups (MGs) to allow for earlier soybean harvest and cover crop planting to maximize cover crop growth. In addition, an integrated cover crop and herbicide management program was evaluated to determine its effect on weed suppression and corn yield. Cover crops have often been shown to be most effective when integrated with other methods of weed management such as herbicides. Cover crops have also been shown to potentially reduce subsequent corn yield. Therefore, we evaluated the influence of cover crop planting date, termination date, and herbicide program on weed density, weed biomass, and subsequent corn yield. Field experiments were conducted in 2017-2019 across six different locations in Nebraska, Ohio, and Kentucky. Results suggest use of early-season soybean MGs allow cover crops to be planted up to 30 days sooner than late-season MGs. Cover crop biomass production was highest for early cover crop planting dates associated with early-season MGs across most site-years evaluated. Soybean yield often plateaued near a 3.0 relative maturity (RM) depending on the region, suggesting that soybean RM may be reduced to 3.0 to allow for earlier cover crop planting without sacrificing soybean yield. Results further suggest that use of a residual herbicide with a postemergence herbicide was necessary to obtain the largest reduction in both weed density and biomass. Weed biomass was occasionally reduced by the cover crop, however, results were inconsistent. Cover crops generally had minimal influence on overall weed suppression, and occasionally resulted in corn yield reduction, indicating the importance of other traditional methods of weed management. Abbreviations: MG, maturity group; RM, relative maturity.
Book Synopsis Effects of Cover Crop Management on Biologically Related Soil Properties in a Mississippi Dryland Soybean System by : Sapana Pokhrel
Download or read book Effects of Cover Crop Management on Biologically Related Soil Properties in a Mississippi Dryland Soybean System written by Sapana Pokhrel and published by . This book was released on 2020 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil microorganisms are important for the stabilization and preservation of a good soil structure. Management practices can affect the diversity and population of microorganisms, which could beneficially change soil properties and promote a more sustainable dryland system. This study was established near Pontotoc, MS on Atwood silt loam to evaluate the impacts of cover crops and fertilizer sources on selected biologically related soil properties in a no-tillage, dryland soybean system. Soil analyses included total carbon and nitrogen, permanganate oxidizable carbon (POXC), easily extractable glomalin-related soil protein (EE-GRSP), water stable aggregate (WSA) and soil pH. Cover crop biomass and percent groundcover, soybean leaf area index (LAI), plant height, and yield were also determined. Results indicated that fertilizer source did have an impact on total nitrogen, EE-GRSP and soybean yield. A positive impact on soil properties is expected with the use of cover crops if studied for a longer period of time.

Book Synopsis Effect of Delayed Cover Crop Termination on No-till Corn and Soybean Production by : Heidi Myer
Download or read book Effect of Delayed Cover Crop Termination on No-till Corn and Soybean Production written by Heidi Myer and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: No-till corn and soybean growers in the mid-Atlantic who use cover crops (CC) typically terminate the cover crops with an herbicide a week or more before cash crop planting. In the interest of extending soil health benefits longer into the spring, some growers are now planting green, (PG) or delaying cover crop termination until cash crop planting or later. Three experiments were conducted to quantify the effects of planting green on corn and soybean production in Pennsylvania. We had three overarching hypotheses across all of the studies: compared to early rye termination, PG would i) increase cover crop biomass, cool and dry soil at planting, and conserve soil moisture later in the growing season; ii) reduce slug damage on cash crops; and iii) not reduce cash crop yield. We conducted one experiment at two Penn State research stations for three years to evaluate cereal rye CC management influences on soybean production. We had three treatments in a split-split plot randomized block design. The main plot was rye seeding rate (34, 67, or 134 kg ha-1), the split plot was topdress nitrogen fertilization rate (34 or 67 kg ha-1), and the split-split plot was rye termination timing (early-killed or planted green). PG increased rye biomass by 48-169%. Soil (0-8 cm) in the PG treatment was generally drier at planting, wetter later and cooler for much of the growing season compared to early-killed rye. PG reduced slug damage compared to early-killed in three of four site-years measured. PG soybeans yielded similarly to the early-killed most consistently when the 2x seeding rate was combined with the lowest N rate. Our results suggest that for best results with PG soybeans, rye seeding rates should be reduced to 67 kg ha-1 or lower, N fertility should be maintained at conservative levels, and rye should be killed early in dry springs.We conducted a second experiment at the same two Penn State research stations for three years to evaluate cover crop management effects on corn production. We had two treatments in a randomized complete block design: cover crop species (crimson clover, cereal rye, or clover + rye mix), and termination timing (early-killed or planted green). We measured similar CC biomass and soil moisture effects of PG as in the soybean experiment, though we found that crimson clover also caused dryer and warmer soils compared to rye or the crimson clover + rye mix. Slug damage was not significantly influenced by PG or CC, contrary to our hypothesis. At Rock Springs, corn yield was 10% lower in PG compared to early across CC in dry 2015, and 12% lower in PG crimson clover compared to early across years, and the main predictors of corn yield were soil moisture and temperature at planting and corn population. We concluded that PG can help manage soil water and corn can maintain similar yields in early-killed CC and PG, but we caution against PG and crimson clover in dry springs due to excessive soil drying and stand establishment complications.The last experiment expanded to include three cooperating farm sites in addition to the two Penn State research stations for three years, and we evaluated cover crop termination timing (early-killed or planted green) effects on corn (4 sites) and soybean (5 sites) production across a range of crop rotations, soils, weather conditions, and equipment. Planting green increased CC biomass 94% to 181% compared to early-kill. Except for two site-years, soil was 8% to 24% drier, and 0.7 to 2.4C cooler at planting in PG compared to early-kill. Slug damage was not different, lower, or higher in PG corn, and not different or lower in PG soybeans compared to early-kill. Our yield stability analysis showed that corn yield was more likely to be reduced by PG in high yielding environments, but there was no difference to a slight benefit in yield at lower yielding environments; conversely, soybean yield was stable across environments regardless of treatment. We conclude that corn was more vulnerable to yield losses from conditions created by PG than soybeans, and growers in environments similar to Pennsylvania hoping to get the most out of their cover crops can plant soybeans green to increase cover crop biomass, and manage soil water, with little risk of yield reduction.
