Download or read book Effect of Soil Test Values and Fertilization on Corn, Soybean and Wheat Tissue Phosphorus and Potassium Concentrations written by Phoo Pye Zone and published by . This book was released on 2019 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Tri-State Fertilization Recommendations were published in 1995 and have provided a framework for phosphorus (P) and potassium (K) nutrient management in field crops. Due to changing soil properties, management practices and advanced crop genetics, there is a need to reassess plant tissue analysis using current soil conditions and modern hybrids. The Tri-State Fertilizer Recommendations use early reproductive leaf nutrient concentrations as a diagnostic of crop nutrient status and grain nutrient concentrations are the basis of fertilizer rates to replace nutrients lost at crop harvest. An evaluation of these nutrient levels in grain and plant tissue samples are therefore important when revising fertilizer recommendations. The goal of this thesis was to evaluate the how crop nutrient levels, especially P and K, are influenced by key soil and management factors. Specific objectives of Chapter 1 were to determine the effects of i) soil test P and K levels and ii) P and K fertilization on early reproductive leaf and grain P and K concentration of corn, soybean and wheat. The specific objective of Chapter 2 was to report grain nutrient concentration and nutrient removal rates in corn, soybean and wheat in Ohio. On-farm P and K fertilizer strip trials in corn, soybean and wheat were conducted at 262 sites in 39 counties across Ohio from 2014 - 2018. At each site, experiments were conducted using a randomized complete block design with 3-4 replications with two treatments, a P or K fertilization treatment and a non-fertilized control. Routine soil nutrient analysis before fertilization, nutrient concentrations in leaves at early reproductive stages, grain yields and grain nutrient concentrations at harvest were measured at each trial. Key site management practices were also recorded through a survey. The effect of soil test P and K level on plant tissue nutrient concentrations was assessed by using regression analysis. Fertilization effects on tissue nutrient concentrations were examined using analysis of variance (ANOVA). Early reproductive leaf and grain P and K concentrations of corn, soybean and wheat generally increased as soil test P and K increased. However, the relationships between soil test levels and nutrient concentrations were weak (all R2

Book Synopsis Soil Fertility and Nutrient Management by : Roma Doshi
Download or read book Soil Fertility and Nutrient Management written by Roma Doshi and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil fertility refers to the ability of a soil to supply plant nutrients. Bioavailable phosphorus is the element in soil that is most often lacking. Nitrogen and potassium are also needed in substantial amounts. For this reason these three elements are always identified on a commercial fertilizer analysis. For example a 10-10-15 fertilizer has 10 percent nitrogen. Inorganic fertilizers are generally less expensive and have higher concentrations of nutrients than organic fertilizers. Also, since nitrogen, phosphorus and potassium generally must be in the inorganic forms to be taken up by plants, inorganic fertilizers are generally immediately bioavailable to plants without modification. However, some have criticized the use of inorganic fertilizers, claiming that the water-soluble nitrogen doesn't provide for the long-term needs of the plant and creates water pollution.
Book Synopsis Improving Potassium Recommendations for Agricultural Crops by : T. Scott Murrell
Download or read book Improving Potassium Recommendations for Agricultural Crops written by T. Scott Murrell and published by Springer. This book was released on 2022 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book highlights concepts discussed at two international conferences that brought together world-renowned scientists to advance the science of potassium (K) recommendations for crops. There was general agreement that the potassium recommendations currently in general use are oversimplified, outdated, and jeopardize soil, plant, and human health. Accordingly, this book puts forward a significantly expanded K cycle that more accurately depicts K inputs, losses and transformations in soils. This new cycle serves as both the conceptual basis for the scientific discussions in this book and a framework upon which to build future improvements. Previously used approaches are critically reviewed and assessed, not only for their relevance to future enhancements, but also for their use as metrics of sustainability. An initial effort is made to link K nutrition in crops and K nutrition in humans. The book offers an invaluable asset for graduate students, educators, industry scientists, data scientists, and advanced agronomists.

Book Synopsis Uniform and Variable-rate Fertilizer and Manure Phosphorus for the Corn-soybean Rotation by : David John Wittry
Download or read book Uniform and Variable-rate Fertilizer and Manure Phosphorus for the Corn-soybean Rotation written by David John Wittry and published by . 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.
