Download or read book Overseeding Annual Ryegrass and Cereal Rye Into Soybean for Winter Forage and as a Cover Crop for Weed Control and Soil Conservation written by Luke B. Smith and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Annual ryegrass (Lolium multiflorum Lam.) and cereal rye (Secale cereale L.) are two forages that fit well into mixed row crop/livestock operations as they can be used both as a cover crop and as a source of winter pasture. Few researchers have studied how to integrate these forages in a soybean [Glycine max (L.) Merrill]-winter pasture-corn (Zea mays L.) rotation. An experiment was conducted where each of these forage species was overseeded at different stages of soybean development, and corn was grown as a subsequent crop. Soybean yield was not altered by overseeding annual ryegrass or cereal rye. All treatments yielded over 2,500 kg ha-1 for the season (with a high of 4,200 kg ha-1), which would supply much needed pasture for winter grazing. While all treatments were adequate sources of forage, overseeding at the R 6.5 stage consistently produced the greatest yields for both annual ryegrass and cereal rye. Forage quality from annual ryegrass was slightly better than for cereal rye, but both had crude protein levels of more than 170 g kg-1 and neutral detergent fiber of less than 559 g kg-1. The overseeded treatments had at least 60% more residue cover and at least 70% less weed cover than did the control plots. Corn yield in the following year was not altered by overseeding. The results of the experiment demonstrate that livestock operations in the lower Midwest could use cereal rye and annual ryegrass overseeded into soybean for winter grazing.

Available in PDF, EPUB and Kindle. Book excerpt: Degradation of soils continues at a pace that will eventually create a local, regional, or even global crisis when diminished soil resources collide with increasing climate variation. It's not too late to restore our soils to a more productive state by rediscovering the value of soil management, building on our well-established and ever-expanding scientific understanding of soils. Soil management concepts have been in place since the cultivation of crops, but we need to rediscover the principles that are linked together in effective soil management. This book is unique because of its treatment of soil management based on principles—the physical, chemical, and biological processes and how together they form the foundation for soil management processes that range from tillage to nutrient management. Whether new to soil science or needing a concise reference, readers will benefit from this book's ability to integrate the science of soils with management issues and long-term conservation efforts.

This book was released on 2016 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Midwestern farmers face the dual challenge of increasing crop production while reducing environmental impacts. Best management practices to decrease nutrient and soil loss in agronomic systems has fueled the resurgence of the cover cropping practice, but many growers are uncertain about the effects that different cover crop species may have in their fields or how combinations of tillage and cover crops may influence yields or soil characteristics. Different cover crop characteristics, such as above and belowground biomass production, nitrogen content, and decomposition may affect both soils and crop yields. Field experiments were conducted across two sites in southern Illinois from 2013 to 2015 to study characteristics of cover crops and the impact of cover crops and tillage on soils, nutrient availability, and agronomic field crop performance. Specifically, these studies 1) determine the effects of cover crops on soil nitrogen, 2) quantify above and belowground biomass production of cover crops, 3) quantify the grain yield and belowground biomass of the following crops of corn (Zea mays L.) and soybeans ( Glycine max L. Merr.), and 4) evaluate cover crop decomposition and nutrient release of a leguminous and non-leguminous species. In both field sites, Hairy vetch (Vicia villosa Roth) treatments produced the most biomass and accumulated the most nitrogen of all cover crop treatments. Cover crop establishment was a problem for the 2014--2015 field season. Cover crops, for the most part, did not have an influence on corn or soybean grain yields, except that corn following Hairy vetch treatments tended to be higher in grain yields than corn following Annual ryegrass treatments. Soybeans following Annual ryegrass treatments tended to be higher in grain yield than soybeans following Canola treatments. Root biomass production was higher for cover cropped plots than non-cover cropped plots (weed root biomass), and corn or soybean root biomass was more affected by tillage practices rather than the main effect of cover crop. Tilled treatments were typically higher in soil nitrate and total inorganic nitrogen compared to No-till treatments, and Annual ryegrass treatments were consistently lower in soil nitrogen compared to other cover crop treatments. Hairy vetch and cereal rye (Secale cereale L.) decomposition and nutrient release was monitored over a 16 week period, with litterbag and intact root core collections at 2, 4, 6, 8, 12, and 16 weeks. Decomposition and nitrogen release data were fit to a single exponential decay model with an asymptote. Cereal rye aboveground (k = 0.14) and belowground (k = 0.19) biomass decomposed more gradually compared to hairy vetch aboveground (k = 0.45) and belowground ( k = 0.68) biomass. The same trend developed for nitrogen release with cereal rye aboveground (k = 0.07) and belowground ( k = 0.19) biomass releasing nitrogen slower and more gradually compared to hairy vetch aboveground (k = 0.61) and belowground ( k = 0.61) biomass. Most of the hairy vetch nitrogen was released around Week 2, but the corn crop did not reach the V6 growth stage until Week 8, therefore cover crop nitrogen release and cash crop uptake may have not been synchronized. Plant Root SimulatorTM ion exchange resin membrane probes also captured significantly more nitrogen in hairy vetch plots compared to cereal rye plots at weeks 2, 4, 6, 8, and 12, which indicates that hairy vetch could increase the readily plant available total nitrogen (nitrate + ammonium) in the soil throughout the bulk of cover crop decomposition. Farmers should decrease the time between cover crop termination and cash crop planting in order to increase the likelihood of crop synchrony. This research will help farmers develop better management practices regarding inclusion of cover crops into traditional agronomic production systems.

Available in PDF, EPUB and Kindle. Book excerpt: Non-Chemical Weed Control is the first book to present an overview of plant crop protection against non-food plants using non-chemical means. Plants growing wild—particularly unwanted plants found in cultivated ground to the exclusion of the desired crop—have been treated with herbicides and chemical treatments in the past. As concern over environmental, food and consumer safety increases, research has turned to alternatives, including the use of cover crops, thermal treatments and biotechnology to reduce and eliminate unwanted plants. This book provides insight into existing and emerging alternative crop protection methods and includes lessons learned from past methodologies. As crop production resources decline while consumer concerns over safety increase, the effective control of weeds is imperative to insure the maximum possible levels of soil, sunlight and nutrients reach the crop plants. - Allows reader to identify the most appropriate solution based on their individual use or case - Provides researchers, students and growers with current concepts regarding the use of modern, environment-friendly weed control techniques - Presents methods of weed management—an important part of integrated weed management in the future - Exploits the knowledge gained from past sustainable weed management efforts

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.
Download or read book Managing Winter Rye for Improving Corn Production Nitrogen Use and Farm Profit written by Christian D. Kessler and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cover crops are often planted during the fallow periods of cash crop harvests to cover the soil and reduce erosion but also to provide other ecosystem benefits including capturing residual nutrients and thus, reducing environmental losses of nitrogen (N) and phosphorus (P) in agroecosystems. Among these cover crops, winter rye (Secale cereale) is popular due to its winter hardiness and relatively cheap seed costs. However, growers in the Midwest, USA are reluctant to use winter rye prior to corn (Zea mays L.) due to the potential yield penalty in corn. This thesis introduces two strategies that could minimize winter rye's effect on corn while providing nutrient loss reduction benefits are precision planting and reducing the seeding rate of winter rye ahead of corn. One study evaluates whether precision planting (planting winter rye strategically to avoid intersecting zones with corn) of winter rye at low seeding rate (37.5 kg ha-1) could produce similar cover crop biomass and quality to normal planted winter rye (50 kg ha-1) and if precision planting can improve performance and N requirement of corn (Chapter 1). The study was conducted in central Indiana during 2020-2021 (CIN21), and southern Illinois during 2021-2022 (SIL22), and 2022-2023 (SIL23) growing seasons. The experiment was arranged in a randomized block design with split plot arrangement. Main plots were three cover crops (a no-cover crop control (NoCC), conventional planted winter rye (CR), and precision planted winter rye (PR). Subplots were six rates of N fertilizer that ranged from 0-280 kg ha-1 for the CIN21 and 0-359 kg ha-1 for SIL22 and SIL23. Our results indicated that shifting from normal planting to precision planting resulted in similar cover crop biomass production with limited effect on winter rye quality [N concentration, Carbon (C):N ratio] and N and C accumulation. In CIN21, the nocover crop control had higher yield and lower N requirements which was consistent with those of SIL22. The economic optimum rate of N (EORN) was below the typical recommended range for central Indiana and was above the recommended range for southern Illinois. Precision planting resulted in a slight increase in corn yield and N requirement, but overall was more profitable than normal planting due to a reduction in the number of seeds required and higher corn to fertilizer prices. Therefore, we recommend that (i) decision support tools for N management in corn should be revised for addition of cover crops in the Midwest, and (ii) precision planting should be implemented instead of normal planting for greater economic benefit. Future research should evaluate ecosystem services of precision vs. normal planting of winter rye over time. The other study evaluates whether planting method of winter rye (precision vs. conventional) at medium and low seeding rates of winter rye influence cover crop biomass production, N and C concentrations and accumulations, and corn performance (Chapter 2). A trial was conducted in 7 site-yrs in Indiana and Illinois during 2020-2021, 2021-2022, and 2022- 2023 growing seasons. The trial was arranged in a randomized complete block design with four replicates. Cover crops [conventional planting (CR) and precision planting (PR)] were factorially arranged with two seeding rates (18.75 vs. 37.5 kg ha-1) for PR and (25 vs. 50 kg ha-1) for CR. Two extra treatments were included as control which were no-cover crop with zero-N and a 224 kg N ha-1 addition to corn. Cover crop biomass, C, N, their uptake, and C:N ratio were evaluated along with corn plant population, and corn grain yield. Our results indicated that winter rye had similar aboveground biomass, N uptake, and C accumulation regardless of planting method and seeding rate suggesting a precision planting at low seeding rate is most economical for cover crop establishment. Corn plant population was only affected by winter rye in one site-yr (CIL23) in which precision planting did not help with minimizing the negative effect of winter rye on corn population. In this study, lack of N fertilization did not decrease corn population but significantly reduced corn grain yield in all site-yrs. Corn grain yield was similar among cover crop treatments (with exception of no cover crop no N) but in one of the site-yrs, precision planting at 18.75 kg ha-1 resulted in greater corn yield than the no-cover crop with 224 N ha-1. We concluded that growers that plant winter rye prior to corn could use precision planting at a seeding rate of 18.75 kg ha-1 to take up residual soil N with limited interference with corn production at a reduced cost compared to conventional winter rye management.
