This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus (P) is an essential nutrient required for crop growth with finite global reserves. Although naturally occurring concentrations of total P in soils may greatly exceed crop demand, quantities of readily plant-available P in soil solution are typically very low. As such, agricultural producers regularly apply P-containing fertilizers to help optimize crop yields. While applications of P fertilizers may improve crop performance, losses of P from non-point agricultural sources are a known contributor to the degradation of surface water quality with excessive P inputs leading to eutrophication, harmful algal blooms, and increased water treatment costs. Acknowledging the importance of P in production agriculture and the role it plays in water quality it is imperative to develop agricultural management systems designed to promote crop yields while protecting water quality. This study explores the interplay between winter grown cover crops and P fertilizer management practice in relation to annual concentrations and loads of total suspended solids, total P, and dissolved reactive P in surface runoff generated by natural precipitation events for a no-till corn (Zea mays)-soybean (Glycine max) rotation located in the Central Great Plains. To explain the mechanisms behind the potential implications of altering cover crop and/or P fertilizer management practice in relation to water quality, this study examined temporal/seasonal variability in surface runoff water quality, changes in soil fertility status, and the impact of winter cereal cover crop species on potential P release and nutrient cycling. The majority of this research was conducted at the Kansas Agricultural Watershed (KAW) field laboratory located near Manhattan, KS, USA, from September 2015 through September 2019. This study utilized three methods of P fertilizer management (no P, fall broadcast P, and spring injected P) each expressed with and without a winter grown cover crop. The spring injected method of P fertilizer application consistently lost less total P and DRP compared to the fall broadcast method of applying P fertilizer highlighting the importance of using P fertilizer placement to protect water quality. Findings from this study show that the addition of a cover crop during a normally fallow period increased dissolved reactive P loss in 3 of 4 years representing an unintended consequence of a traditionally recognized conservation practice. Cover crops also decreased sediment loss with greater reductions in sediment loss coming from the P fertilized cover crop treatments. Soil test data for samples collected from KAW field lab found that spring subsurface placement of P fertilizer did not result in lesser concentrations of either Mehlich-III not total P in the top 0-5 cm compared to fall broadcast P. The spring injected P fertilizer without a cover crop treatment had lesser concentrations of water-extractable P (WEP) in the top 0-2.5 cm compared to the fall broadcast with and without cover crop treatments; however, when a cover crop was added to the spring injected treatment, WEP was found to be equal to the two fall broadcast treatments The final portion of this research was conducted from fall 2019 through fall 2021 at locations near both Manhattan, KS, USA and Leonardville, KS, US, and examined the impact of six choices in winter cereal cover crops [included winter barley (Hordeum vulgare), winter oat (Avena sterilis), cereal rye (Secale cereale), triticale (X Tritico-secale), winter wheat (Triticum aestivum), and Cereal Killer Blend (1:1:1:1 of barley:oat:rye:triticale)] on P release from cover crop tissue, residue persistence, and the effect of cover crop choice on nutrient cycling throughout the cash crop growing season. This study found winter wheat to have the greatest potential for P release immediately following termination; however, after one week post termination, P concentrations in winter wheat residues were similar to other observed cover crops. Oats were observed to have lowest residue persistence and also to release assimilated nutrients faster than the remaining species. Marginal differences between winter barley, cereal rye, and triticale were observed with regards to P concentration, residue persistence, and nutrient cycling; however, these differences were not biologically significant. Results from this and the aforementioned studies highlight the importance and implications of management decisions when developing agricultural management practices to protect surface water quality.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Nano-Fertilizer Synthesis and Types?discusses the production of a variety of nano-fertilizers, including biological, chemical, and mechanical types. Nano-fertilizers aid in nutrition control by increasing nutrient consumption efficiency as nutrients are bonded to nano-dimensional adsorbents, which in turn release nutrients considerably more slowly than traditional fertilizers. As the nano-fertilizer sector advances, one approach is to concentrate on macro elements (N, P, K), as switching to nano-fertilizers may result in significant environmental benefits by replacing the majority of these nutrients. Furthermore, the biosynthesis of nanomaterials employing bacteria, algae, yeast, fungus, actinomycetes, and plants has opened up a new field of study for the creation of inorganic nanoparticles as environmentally benign fertilizers. Because of the several-fold increase in the surface-to-volume ratio of nano-forms of nutrients, and their appropriateness for foliar application, where environmental losses are further decreased, nano-fertilizers may achieve higher efficiency. However, before nano-fertilizers are manufactured and commercialized, further research should be conducted to assess their impact for both humans and the environment. While there are some nano-fertilizer products available, the nano-fertilizer production industry still requires additional public and private sector support and development. Nano-Fertilizers Synthesis and Types presents the latest information, highlights the benefits and impacts of each, and provides a single-volume resource to help effectively and efficiently identify options based on use-case. Exploring the topic from the various mechanistic types to the relevant regulatory, safety, and economic aspects, this volume will be appropriate for those working with and researching new nano-fertilizers. Guides in the identification of appropriate nano-fertilizer options based on use-case Addresses both target plant and environmental considerations Includes economic and regulatory insights

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 2002 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Precision agriculture has evolved from a concept into an accepted management practice. The challenge now is how to best utilize these technologies for the benefit of agriculture. Nutrient management could be improved and spatial variability reduced by variable-rate (VR) application. The objectives of this dissertation were to assess the value of VR P fertilization and P-based liquid swine manure application for corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] production compared with the traditional uniform-rate (UR) application. On-farm research methods based on replicated, long narrow strips were adapted to precision technologies. These technologies included grain yield monitors, differential global positioning systems, and geographical information systems. Treatments consisted of a non-fertilized control, a UR method based on average soil-test P (STP) for the entire field and a VR method based on STP from 0.2 to 1.7 ha grid cells. Grain yield and temporal changes in STP were used to assess treatment differences in both studies. In addition, plant dry weight, P concentration, and P uptake (V5 growth stage) were used in the fertilizer study. Phosphorus fertilization and manure often increased whole-field crop grain yield in fields which average STP values were below the Optimum interpretation class for corn and soybean production. Analyses of yield for field areas with contrasting STP values often showed significant responses to fertilizer or manure P in field areas testing Optimum or less, but rarely in high-testing areas. Phosphorus fertilization increased early plant growth and P uptake more frequently than grain yield. Although the method of P application did not influence whole-field or within-field plant responses, VR reduced soil P variability compared with UR by increasing STP in low-testing areas and decreasing or not affecting STP of high-testing areas. This research showed precision farming technologies are useful tools for improving nutrient management. Fertilization or manure application programs that vary the nutrient application rate may not result in increased yield compared with UR application methods. However, use of VR technology will result in better nutrient management and perhaps better water quality because of more efficient distribution of fertilizer or manure.

Book excerpt: In Soil Fertility Management in Agroecosystems, Editors Amitava Chatterjee and David Clay provide a thoughtful survey of important concepts in soil fertility management. For the requirements of our future workforce, it is imperative that we evolve our understanding of soil fertility. Agronomists and soil scientists are increasingly challenged by extreme climatic conditions. Farmers are experimenting with integrating cover crops into rotations and reducing the use of chemical fertilizers. In other words, there is no such a thing as a simple fertilizer recommendation in today's agriculture. Topics covered include crop-specific nutrient management, program assessment, crop models for decision making, optimization of fertilizer use, cover crops, reducing nitrous oxide emissions, natural abundance techniques, tile-drained conditions, and soil biological fertility.
