Available in PDF, EPUB and Kindle. Book excerpt: Efficient management of rice (Oryza sativa) nutrition across soils ranging from organic to mineral soils varies widely due to large contributions of nutrients, including N, from the indigenous supply. This study tested the hypothesis that the indigenous N supply (INS) would increase if the SOC content of the rice paddy soil increased, evaluated across a wide range of soil organic carbon (SOC) content. The INS, defined as N uptake from N omission plots, was estimated from 54 plots over a three year period at two locations in the Sacramento-San Joaquin Delta over a range of SOC from 6 to 232 g SOC kg−1. Additionally ten N rate trials (0 to 160 kg N applied ha−1) were conducted concurrent with the N omission plots. The INS did not increase as SOC increased across the entire SOC gradient, and instead exhibited a concave quadratic trend across the SOC gradient; greatest in the 110-170 g SOC kg−1 range and lower in sites with less than 110 g SOC kg−1 or more than 170 g SOC kg−1. Consequently, positive yield response to N fertilizer was observed in soils with low INS, with no positive yield response on soils with high INS. This study indicates that the INS can be predicted by the SOC content, hence fertilizer-N recommendations should include considerations for SOC content.

Available in PDF, EPUB and Kindle. Book excerpt: This volume addresses three important agricultural aspects of rice: physical characteristics, physico-chemical characteristics, and the organoleptic aspects. Divided into sections, the book first examines recent trends and advances for higher production and quality improvement, focusing on the effects of climate on rice cultivation and climate-resilient agricultural practices in rice. The volume goes on to cover nutrient management for rice production and quality improvement. Chapters also address weed management and postharvest processing practices for improved rice production. With chapters from renowned scientists, researchers, and professors, this book will be a useful reference for rice researchers working in the area of agronomic practices, postharvest processing, and quality improvement in rice.
Download or read book Soil Nitrogen Uses and Environmental Impacts written by Rattan Lal and published by CRC Press. This book was released on 2018-03-15 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen (N) is potentially one of the most complex elements on the Earth. It is necessary for all biological activity, but creates negative impacts on water and air quality. There is a balancing act between deficiency and surplus and the forms of N available further complicate our understanding of the dynamics. Biological fixation provides some plants with N supply while others are totally dependent upon N being available in the soil profile for the roots to extract. Nevertheless, the demand for N will increase because the human population with its increasing growth requires more protein and thus more N. Understanding the global N cycle is imperative to meeting current and future nitrogen demands while decreasing environmental impacts. This book discusses availability, production, and recycling of N in air, water, plants, and soils. It features information on N impacts to soil and water quality, management of N in agroecosystems, and techniques to maximize the use efficiency while minimizing the risks of leakage of reactive N into the environment. This volume in the Advances in Soil Science series is specifically devoted to availability, production, and recycling of N with impact on climate change and water quality, and management of N in agroecosystems in the context of maximizing the use efficiency and minimizing the risks of leakage of reactive N (NO-3, N¬2O) into the environment.

Download or read book Nitrogen in Agriculture written by Khan Amanullah and published by BoD – Books on Demand. This book was released on 2018-02-01 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is the most yield-restraining nutrient in crop production globally. Efficient nitrogen management is one of the most important factor for improving nitrogen use efficiency, field crops productivity and profitability. Efficient use of nitrogen for crop production is therefore very important for increasing grain yield, maximizing economic return and minimizing nitrous oxide (N2O) emission from the fields and nitrate (NO3) leaching to ground water. Integrated nitrogen management is a good strategy to improve plant growth, increase yield and yield components, grain quality and reduce environmental problems. Integrated nitrogen management (combined use of chemical + organic + bio-fertilizers) in field crop production is more resilient to climate change.
