Profitability and uptake of nitrogen application system based on remote sensing on 90 commercial farms in the United Kingdom

摘要

There has been an increase in demand for more efficient ways of applying nitrogen. SOYL Ltd, UK used the nitrogen guidelines developed through a Home Grown Cereals Authority, UK precision farming research project and implemented it commercially over 90 farms in spring 2006. The paper outlines any benefits in profit, yield and nitrogen usage delivered on farm. Problems with the implementation of a remote sensed based system in real time are discussed.
