Development of measurement technologies to increase productivity, nitrogen use efficiency and nitrogen management decisions for grass crops

目前在农场实现的牧草产量还不到英国环境生物潜力的一半。牧草产量低的主要原因之一是氮肥的使用不够理想，没有考虑到农田内氮肥需求的空间差异。目前估计化肥氮素需求量的方法很复杂，而且没有根据作物需要而变化地施氮量的方法。该项目旨在开发用于可耕种作物(YARA N传感器)的技术，以测量草本作物的氮肥需求。这将为农民提供一种简单、自动化的方法，更精确地控制他们的草类作物的氮肥施用量。好处包括更高的草产量，更大的农场盈利能力和环境效益，如减少温室气体排放和降低硝酸盐淋失风险。该联盟由YARA(牵头和N制造商)、ADAS(管理和研究)、Precision Decision(技术)、Countrywide Farmers(知识转移)和DLF Trifolium(牧草育种者)组成。这个免费的联合体确保了世界级的技术专业知识以及有效的开发途径。

Grass yields currently achieved on-farm are less than half of the biological potential for the UK environment. One of the main reasons for low grass yields is the sub-optimal use of nitrogen (N) fertiliser and failure to account for spatial variation in N fertiliser demand within fields. Current methods of estimating fertiliser N requirements are complex and there is no method for variably applying N according to crop needs. This project aims to develop technology used on arable crops (Yara N-Sensor) to measure the N fertiliser requirement of grass crops. This will provide farmers with a simple, automated method of controlling more precisely the amount of N fertiliser applied to their grass crops. The benefits include greater grass yields, greater farm profitability and environmental benefits such as fewer greenhouse gas emissions and a lower risk of nitrate leaching. The consortium consists of Yara (lead & N manufacturer), ADAS (management & research), Precision Decisions (technical), Countrywide Farmers (knowledge transfer), and DLF Trifolium (grass breeders). This complimentary consortium ensures world class technical expertise alongside an effective route for exploitation.
