Book Description
Selection of economically optimal levels of nitrogen fertilization is an important farm management problem. Fertilization levels chosen will depend on agronomic and economic factors. Many farmers have already adopted or are considering adoption of no-tillage corn cultural practices. The objective of this publications was to determine the economically optimal levels of nitrogen fertilization for no-tillage and conventional tillage corn cultural practices. The economically optimal levels of fertilization presented on this publication were based on data collected form nitrogen rate by tillage experiments conducted by The University of Maryland Department of Agronomy at four research farms during 1979 to 1983. Corn yield response to nitrogen fertilization functions were estimated for each farm location, tillage system and year in which the experiment was conducted. The corn yield response to nitrogen and the economically optimal rates of nitrogen fertilization derived from the yield response functions varied according to farm location, cultural practice and year in which the experiment was conducted. Yield responses at certain locations exhibited large variations, while yield response at other locations were relatively consistent. Changes in yield response and/or the prices of nitrogen and corn may change the economically optimal rate of fertilization, however, large changes in nitrogen and corn prices may not lead to large changes in economically optimal rates of fertilization.

Managing Cover Crops Profitably (3rd Ed. )
Author: Andy Clark
Publisher: DIANE Publishing
ISBN: 1437903797
Category : Technology & Engineering
Languages : en
Pages : 248
Book Description
Cover crops slow erosion, improve soil, smother weeds, enhance nutrient and moisture availability, help control many pests and bring a host of other benefits to your farm. At the same time, they can reduce costs, increase profits and even create new sources of income. You¿ll reap dividends on your cover crop investments for years, since their benefits accumulate over the long term. This book will help you find which ones are right for you. Captures farmer and other research results from the past ten years. The authors verified the info. from the 2nd ed., added new results and updated farmer profiles and research data, and added 2 chap. Includes maps and charts, detailed narratives about individual cover crop species, and chap. about aspects of cover cropping.
