This book was released on 1987-08-31 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: On the occasion of its twenty-fifth anniversary, in 1985, the Netherlands Society for Grassland and Fodder Crops (NVWV) agreed to organize an International Symposium on a topic related to intensive grass and fodder production systems. The theme selected was "Animal manure on grassland and fodder crops: Fertilizer or waste?" This Symposium was organized under the auspices of the European Grassland Federation and held at the International Agricultural Centre in Wageningen from 31 August to 3 September 1987. The problems connected with the disposal of animal waste have received much attention in recent years, especially in regions with intensive animal of animal manure per hectare agricul husbandry. Whereas the production tural land increased strongly, the need for it decreased because of the introduction of cheap inorganic fertilizers which are easier to handle and have a more reliable effect on crop growth. As a consequence, many farmers dispose of animal manure as cheaply as possible, whilst avoiding damage to grassland and crops and paying little attention to effective use of the plants nutrients contained in the manure. Present practices of manure handling and application often lead to environmental problems. The rise in awareness of these problems renewed interest in possibilities to improve the utilization of nutrients from animal manure in crop production. Research on this topic has been stimulated in many countries during the last decade and the aim of this Symposium was to review and assess present-day knowledge.

Download or read book Modelling water and nutrient dynamics in soil crop systems written by K.Ch. Kersebaum and published by Springer Science & Business Media. This book was released on 2007-05-10 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains articles from a workshop on the modeling of water and nutrient dynamics in crop-soil systems. Data sets from lysimeters and experimental fields of multiyear crop rotations were provided for modelers. A unique data set is provided of a 100-year, long-term field experiment into crop yield and organic carbon development under different management systems. The book includes a detailed description of data sets which can be used by modelers and the papers describe the applications of 18 different modeling approaches.
Download or read book Nitrogen in Organic Wastes written by Bozzano G Luisa and published by Academic Press. This book was released on 2012-12-02 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic wastes are traditionally applied to land to recover their fertilizer value, but the microbial turnover of such organic matter in soil is often out of phase with the requirements of growing plants. Therefore, nutrients may be lost and may even act as potential pollutants of water and air, posing a particular challenge to agricultural and environmental engineers. This book addresses both experimental and modeling methodology under the main headings of nitrogen and carbon transformations, gaseous losses, chemical means of controlling nitrification, and nitrate leaching. The articles are based on material presented at a specialized seminar held under the auspices of ISWA and DAKOFA at Aalborg University, Denmark, in September, 1988.
