This book was released on 2015 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigated soil quality under corn (Zea mays L.) -- soybean (Glycine max L.) rotation as affected by cereal rye (Secale cereal L.) cover crop in the U.S. Corn Belt. The objectives were to 1) examine the affect of cereal rye cover cropping on various physiochemical soil quality indicators, including bulk density and total porosity, plant available water content, soil organic carbon concentration and stock, total nitrogen concentrations and stock, pH, cation exchange capacity, and clay activity ratios to a depth of 60 cm; 2) integrate several of these soil surface (0---10 cm depth) quantitative parameters into a unit less soil quality index (SQI); and 3) examine the affect of cereal rye cover cropping on corn and soybean yields.three case studies were investigated with soil samples taken in 2011 and crop yields over four growing seasons. These case studies were on a Mollisol (Nicollet series: Fine-loamy, mixed, superactive, mesic Aquic Hapludoll) in northwestern Iowa, an Alfisol (Nabb series: Fine-silty, mixed, active, mesic Aquic Fragiudalf) in southeastern Indiana, and an Alfisol (Capac series: Fine-loamy, mixed active, mesic Aquic Glossudalf) in central Michigan.

Download or read book Soil Management written by Jerry L. Hatfield and published by John Wiley & Sons. This book was released on 2020-01-22 with total page 432 pages. 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.

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.

Download or read book Three year Soybean wheat corn Rotation Benefits on Soybean Production Soil Health and Soil Bacterial Community are Site and Year Dependent written by Daowen Huo and published by . This book was released on 2020 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: Higher crop rotational diversity can improve crop productivity, soil health and soil microbial diversity. This research hypothesized that three-year (3-yr) rotation of soybean-corn-wheat would have higher soybean productivity, better soil health and more diverse soil bacterial community compared to two-year (2-yr) soybean-corn rotation. A rotation experiment was established in 2013 at two research sites in Ohio. Soybean seedling establishment and biomass, crop yield and soil were collected in 2018 and 2019. Higher seedling stand and biomass, and soybean yield were observed in the 3-yr rotation but the results were not consistent across all site-year combinations. Soil organic matter was higher in the 3-yr rotation at three out of four site-years. Similarly, higher soil carbon, nitrogen and active carbon was detected in the 3-yr rotation at one site-year. The bacterial community at NWARS and WARS also different. However, at each site, the diversity of soil bacteria, sampled at soybean seedling stage, did not differ between the 2-yr and 3-yr rotation. Seven major phyla and nine core bacterial sequence variants were found in samples from all treatments. Nevertheless, compared to the 2-yr rotation, the 3-yr rotation had a unique set of six taxa, absent in the 2-yr rotation samples, and higher abundance of Pseudomonas sequence variants and lower abundance of Ralstonia sequence variants. Most of the 3-yr rotational benefits were detected on site-year combinations where environment and weather conditions were unfavorable to soybean growth, such as poorly drained soil, high precipitation, and fewer growing degree days. Hence, under unfavorable conditions, the 3-yr rotation of soybean-corn-wheat is recommended for soybean and soil benefits.

Download or read book Soil Fertility and Corn and Soybean Yield and Quality in a Six year Nitrogen and Phosphorus Fertilization Experiment written by Peter M. Anthony and published by . This book was released on 2012 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimum management of nitrogen (N) and phosphorus (P) fertilizers for corn [Zea mays L.] and soybean [Glycine max (L.) Merr.] production requires quantitative understanding of multiple soil processes and crop responses, including supply and immobilization of N and P by soil, the response of yield and quality to nutrient availability, and the relationships and interactions between N and P cycling, crop response, and other soil physical and chemical variables. We conducted a six-year experiment on two 16-ha fields on glacial-till soils in south-central Minnesota. In each year of a corn-soybean rotation, we measured soil physical and chemical parameters and grain yield and quality at a 0.014-ha resolution within each field. These observations coincided with placement of a randomized complete block, split plot design of N and P fertilizer treatments. Spatial patterns of mineralizable N were consistent over time. Mineralizable N was highly correlated to soil nitrate at a well-drained site, but not at a poorly-drained site. Increases in available soil P per kg of net P addition were significantly related to soil pH. Within fields, spatial patterns of soybean yields were highly correlated across years, and we observed consistent relationships between yield and soil variables. Overall, soybean yield related positively to soil P and Zn and negatively to pH at all site-years. Quadratic-plateau regression models of soybean yield in relation to soil P and Zn indicate that in high pH soils at these sites, yield is optimized when soil P and Zn levels are higher than current recommendations. Corn yields responded significantly to N rate and N rate by P rate interaction in all site-years. Whole-field economic optimum N rate differed significantly by site-year and by P treatment at some site-years. Site-specific P fertilization should account for spatial variation in soil P buffering capacity. Nitrogen mineralization and NxP nutrient interactions should be accounted for in agronomic management decisions for corn production. The consistent influence of soil pH on nutrient cycling and crop response indicates the potential benefit to amelioration of high pH in calcareous glacial-till soils. Results highlight the significance of spatial variability in nutrient cycling to crop management.
