Book excerpt: This book mainly presents the current state of knowledge on the use of of Silicon (Si) in agriculture, including plants, soils and fertilizers. At the same time, it discusses the future interdisciplinary research that will be needed to further our knowledge and potential applications of Si in agriculture and in the environmental sciences in general. As the second most abundant element both on the surface of the Earth’s crust and in soils, Si is an agronomically essential or quasi-essential element for improving the yield and quality of crops. Addressing the use of Si in agriculture in both theory and practice, the book is primarily intended for graduate students and researchers in various fields of the agricultural, biological, and environmental sciences, as well as for agronomic and fertilizer industry experts and advisors.

This book was released on 1977 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Liming is usually aimed at eliminating such effects deleterious to plant growth as low pH, low base status, aluminum and/or manganese toxicity, and P fixation. In the present study, field and greenhouse experiment were conducted to study the effect of lime application (as calcium hydroxide) on maize growth and some soil properties. The work was conducted on an Ultisol in the forest region of Ghana. Results from both cultivated and uncultivated soil samples indicate that the subsoil were very low in available P, exchangeable Ca, Mg, and K when compared to the surface soils. On the other hand, P adsorption isotherms showed that the subsoils had higher adsorption maxima, an indication that the high clay content and aluminium saturation contributed to the high Pfixing capacity of the subsoil. Field results showed that liming did not have an effect on the bicarbonate-extractable P (Olsen), 0.1M HC1-extractable Zn, CEC, and exchangeable Mg of the top soil. pH and exchangeable Ca increased with increased lime application. The subsoil was not affected by liming the top soil, which may indicate that there was little or no leaching of Ca over the period of the experiment. Lime application did not significantly increase maize grain yield in either the major or minor growing season. The first increment of lime (0.5 t/ha) increased grain yield economically in both seasons, but subsequent lime levels did not. A yield depression occurring at the highest lime rate (4 t/ha), when compared to the check plots where no lime (...).

Download or read book Interpreting Soil Test Results written by Pam Hazelton and published by CSIRO PUBLISHING. This book was released on 2016-11-01 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interpreting Soil Test Results is a practical reference enabling soil scientists, environmental scientists, environmental engineers, land holders and others involved in land management to better understand a range of soil test methods and interpret the results of these tests. It also contains a comprehensive description of the soil properties relevant to many environmental and natural land resource issues and investigations. This new edition has an additional chapter on soil organic carbon store estimation and an extension of the chapter on soil contamination. It also includes sampling guidelines for landscape design and a section on trace elements. The book updates and expands sections covering acid sulfate soil, procedures for sampling soils, levels of nutrients present in farm products, soil sodicity, salinity and rainfall erosivity. It includes updated interpretations for phosphorus in soils, soil pH and the cation exchange capacity of soils. Interpreting Soil Test Results is ideal reading for students of soil science and environmental science and environmental engineering; professional soil scientists, environmental scientists, engineers and consultants; and local government agencies and as a reference by solicitors and barristers for land and environment cases.
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.

Download or read book Maize Crop written by A. Solaimalai and published by CRC Press. This book was released on 2020-05-10 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maize is one of the versatile emerging crops with wider adaptability under varied agro-climatic conditions. Globally, maize is known as queen of cereals because it has the highest genetic yield potential among the cereals. It is cultivated on nearly 150 m/ha in about 160 countries having wider diversity of soil, climate, biodiversity and management practices that contributes 36 % (782 m/t) in the global grain production. The United States of America (USA) is the largest producer of maize contributes nearly 35 % of the total production in the world. It is the driver of the US economy. This book talks about the improvement, production, protection and post harvest technology of the maize crop. Note: T& F does not sell or distribute the Hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka.
Download or read book Plant Nutrient Acquisition written by N. Ae and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: New research reveals that plants actively acquire nutrients; the acquisition process is not a passive one in which plants simply wait for dissolved nutrients to come closer to their roots. In fact plants play a far more active role than once was understood to be possible in nutrient acquisition and in adaptation to problem soils. This book presents an excellent overview and summary of new concepts of plant nutrient acquisition mechanisms, and sets forth their practical implications in crop production. The scope is wide ranging, from biochemical, molecular, and genetic analysis of nutrient acquisition to global nutritional problems. Especially noteworthy are the sections on the cell apoplast, phosphorus-solubilizing organisms, and direct uptake of macro-organic molecules. With contributions by leading scientists worldwide, the book provides an invaluable resource for researchers in plant and environmental sciences and in agronomy and other branches of agriculture.
