This book was released on 1981 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Critical nutrient percentage is defined as the nutrient concentration associated with maximum yield with respect to the nutrient. Objectives of this research were: (1) to compare three methods for calculating maximum yield and associated critical % N and to determine effects of time of leaf sampling at or near silking on critical % N; (2) to determine effects of P fertilizer rates on critical % N and of N rates on critical % P; and (3) to determine effects of crop sequence, plant density, and moisture stress on critical % N and % P in both grain and leaf. Data were from 39 fertilizer experiments at 4 outlying research centers in Iowa. The direct regression method (Yield on % N in the plant part) was generally poorer for estimating critical % N in the grain and leaf than the two-step method (yield and % N on N rates) or graphical method (highest yield based on significance and associated % N). The latter two were similar. Time of leaf sampling and weather factors prior to and during silking affected % N of treatments and critical % N. The P rates increased critical % N in grain as mich as 0,12% and that leaf as much as 0.16%. As N rates increased, critical % P decreased as much as 0.028% in the grain and increased as much as 0.58% in the leaf. The critical % N and % P in the grain of leaf can evaluate N and P fertility status of corn better if levels of both are considered. The critical % N and % P in both grain and leaf were slightly less in C2 than in C1 in a C1-C2-soybean roatation. Increased stand level (...).

This book was released on 2001-12-03 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen in the Environment: Sources, Problems, and Management is the first volume to provide a holistic perspective and comprehensive treatment of nitrogen from field, to ecosystem, to treatment of urban and rural drinking water supplies, while also including a historical overview, human health impacts and policy considerations. It provides a worldwide perspective on nitrogen and agriculture. Nitrogen is one of the most critical elements required in agricultural systems for the production of crops for feed, food and fiber. The ever-increasing world population requires increasing use of nitrogen in agriculture to supply human needs for dietary protein. Worldwide demand for nitrogen will increase as a direct response to increasing population. Strategies and perspectives are considered to improve nitrogen-use efficiency. Issues of nitrogen in crop and human nutrition, and transport and transformations along the continuum from farm field to ground water, watersheds, streams, rivers, and coastal marine environments are discussed. Described are aerial transport of nitrogen from livestock and agricultural systems and the potential for deposition and impacts. The current status of nitrogen in the environment in selected terrestrial and coastal environments and crop and forest ecosystems and development of emerging technologies to minimize nitrogen impacts on the environment are addressed. The nitrogen cycle provides a framework for assessing broad scale or even global strategies to improve nitrogen use efficiency. Growing human populations are the driving force that requires increased nitrogen inputs. These increasing inputs into the food-production system directly result in increased livestock and human-excretory nitrogen contribution into the environment. The scope of this book is diverse, covering a range of topics and issues from furthering our understanding of nitrogen in the environment to policy considerations at both farm and national scales.

This book was released on 2012-12-06 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing a link between theoretical and applied aspects of plant nutrition and agriculture, this book introduces new concepts in plant nutrition. It shows how these can be applied in order to assess the nitrogen status in crops and to improve nitrogen nutrition through optimized N fertilization management. In this way economic benefits can be obtained, while at the same time preventing detrimental effects on the environment. The main agricultural crops - grasses, wheat, barley, Durum wheat, maize, sorghum, grain legumes and potatoes - are covered. The book will be an invaluable source for agronomists.

Download or read book GROWTH and Nutrient Uptake by Corn written by and published by . This book was released on 1960 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through the process of photosynthesis, corn plants use energy from sunlight to manufacture sugar from carbon dioxide in the air and water and nutrients in the soil. This sugar is then converted to starches, proteins and other compounds that make up the dry weight of the plant. Essentially, all phootsynthesis occurs in the leaves. Generally, then, the more leaf area an adapted plant has, the more dry weight it will produce. Corn leaves are produced early in the growing season-largely before mid-julay-then the stalk and tassel form, then the husks, cob, etc., and finally the grain. But the potential amount of grain that can be produced at the end of the season depends upon the leaf area produced early in the season. Early dry matter accumulation in the corn plant is slow. Leaf area then is small. As more leaf area is available, the amount of photosynthesis and dry matter accumulation increases. (...).

Download or read book Advances in Silage Production and Utilization written by Thiago Da Silva and published by BoD – Books on Demand. This book was released on 2016-11-16 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ensiling is a technique that is used to store food, mainly vegetable crops, to feed the herd when the forage supply from the pastures is not enough to maintain the productive performance of the ruminant animals. However, silage can also be used as substrate for biogas production and other different purposes. In the past years, we have seen many advances in the knowledge about silage production utilization, and this book is a compilation and discussion of the outstanding scientific research activities concerning actually the most recent advances and technologies that have been studied about silage and future demands. It is directed to a broad public of readers - farmers, academics, students, or anyone just curious or interested in the subject.
