Book Description
Research was conducted from the fall of 2014 to the fall of 2016 to evaluate the optimal utilization of cover crops for weed control in no-till environments. Studies included a corn (Zea mays L.) termination timing study to evaluation different termination intervals of cereal rye (Cereal rye L.), hairy vetch (Vicia villosa Roth.), and a combination of cereal rye and hairy vetch cover crops on corn growth and development, an evaluation of a roller crimper for cover crop termination prior to corn study, an evaluation of a roller crimper for cover crop termination prior to soybeans [Glycine max (L.) Merr.], an evaluation of glyphosate + dicamba tolerant (GDT) soybean utilization in a cover cropping system, and a study to evaluate the effects of fall applied herbicides on four cover crop species from controlling Italian ryegrass (Lolium perenne ssp. multiflorum). Results from this research indicate that a cover crop termination interval prior to corn planting can influence corn growth, development, and yield, a roller crimper is not currently a viable tool for cover crop termination prior to planting corn, a roller crimper can be effectively used for cover crop termination prior to soybeans, GDT soybeans can be readily utilized into a cover cropping system, and that fall applied herbicides can be used with cover crops and aid in controlling Italian ryegrass.

Book Description
Fall-seeded cover crops are limited by the short growing season remaining between harvest and planting the succeeding crop. To address this challenge, we considered two alternative systems for introducing cover crops into corn (Zea mays L.)- soybean (Glycine max L.) cropping systems. The first alternative was to interseed the cover crops species with corn at specific developmental stages. We evaluated the effect on corn, cover crop biomass, and the subsequent soybean crop. No detrimental effects on corn were found when cover crops were interseeded at or after corn canopy closure due to the limited cover crop biomass produced during the growing season. However, corn was negatively affected with cover crops interseed at corn planting. Cover crops interseeded at canopy closure did not establish due to corn canopy shading. Cover crops interseeded at or after R5 (dent) produced greater biomass the following spring than in the fall, and cover crops interseeded at R5 and R6 (physiological maturity) produced greater biomass than cover crops interseeded at corn harvest. This indicated that the interseeding by broadcasting cover crops can be successful for improving biomass production. The second alternative was to modify corn management practices such as planting date, plant population, and comparative corn relative maturity (CRM) to allow earlier cover crop seeding dates. We attempted to understand the impact on corn yield, cover crop biomass production, and the subsequent soybean crop. Early- and early-to-medium-maturity hybrids allowed corn harvest about one month earlier and medium-maturity hybrids about 15 d earlier than late-maturity hybrids. No differences in corn yield were observed between the medium- and late-maturity hybrids planted at the earlier planting date, with a 107 CRM hybrid planted early having the highest yield of 16.0 Mg ha-1. The greatest cover crop biomass production occurred with the earliest cover crop planting date. Cover crop biomass increased with air temperature, which was measured with growing degree days (GDDC). This indicates that changes in planting date and corn CRM hybrids are important to increase the potential for use of cover crops. The subsequent soybean yield was not affected by cover crops in either alternative.

Book Description
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.

Book Description
Cover crops slow erosion, improve soil, smother weeds, enhance nutrient and moisture availability, help control many pests and bring a host of other benefits to your farm. At the same time, they can reduce costs, increase profits and even create new sources of income. You¿ll reap dividends on your cover crop investments for years, since their benefits accumulate over the long term. This book will help you find which ones are right for you. Captures farmer and other research results from the past ten years. The authors verified the info. from the 2nd ed., added new results and updated farmer profiles and research data, and added 2 chap. Includes maps and charts, detailed narratives about individual cover crop species, and chap. about aspects of cover cropping.
