Download A Method of Economic Analysis Applied to Nitrogen Fertilizer Rate Experiments on Irrigated Corn Book in PDF, ePub and Kindle
Marginal economic analysis can be applied to the relationship between nitrogen fertilizer as an input factor and crop yields to determine the rate of application of fertlizer thet will maximize returns from its application. This method of analysis is supplemental to other analyses of experimental data by methods specified by the designs of agronomic experiments. This bulletin reports on the application of a method of economic analysis illustrated by experimental results fom plots designed to test the application of nitrogen fertilizer on irrigated corn in Oregon, Washington, and Nebraska. Under existing information, the exponential function (Y1 = M - ARxi) is a logical function to represent the relationship for the application of a single input. This functionis used to represent the yield response curve of eperimental data. Unless the economic implications of the most profitable rate in terms of the comparative returns to nitrogen are observed, the relative importance of different rates may be overlooked. The most profitable rate of application at which returns to nitrogen will be maximized may be identical for two different situations but the returns to nitrogen may differ greatly. The comparative returns to nitrogen form the primary criterion by which one situation can be selected over the other. Differences between the most profitable rates of nitrogen application for an estimated yield curve and its confidence limit curves may be substantial, but the differences in the return to nitrogen are small. The (...).

Download Nitrogen Turnover in the Soil-Crop System Book in PDF, ePub and Kindle
In the Netherlands the Institute for Soil Fertility Research plays a major role in soil biological, soil physical and plant nutritional research on the availability of nitrogen to crops. Main subjects of research are nitrogen turnover in the crop-soil ecosystem through biological transformations, nitrogen transport through the soil and nitrogen losses by leaching, denitrification and volatilization, and nitrogen use efficiency of various crops and cropping systems. The current knowledge in the different fields of research is integrated in simulation models. Simulation models not only make it possible to summarize and structure knowledge, but also, after verification, to extra- late the knowledge to situations different from the situations that have actually been studied. Such research is also carried out in other European and non-European countries. To compare the various simulation models currently in use, a workshop was organized by the Institute for Soil Fertility Research on 5-6 June 1990 on the occasion of its centennial. The title of the workshop was 'Nitrogen turnover in the soil-crop ::cosystem: modelling of biological transformations, transport of nitrogen and nitrogen use efficiency'. The 40 Jarticipants, who came from Canada and various European countries, were requested to run their model with data Jrovided by the Institute prior to the workshop. Data from 18 cases were made available to the participants: three ocations, three treatments, and two seasons.
