July 2015: Sino-UK Newton AgriTech Project

The kickoff meeting of the Sino-UK Newton AgriTech Project “Remote Sensing for Sustainable Intensification in China through Improved Farm Decision-Making” was held from July 2nd to 6th in Changchun, Jilin Province. The participants visited the Research Sites and the Science and Technology Backyards in Lishu. The UK participants also visited the CAU Jiansanjiang Experimental Station and the Science and Technology Backyard. Dr. John Crawford from Rothamsted Research presents the UK PI and Dr. Yuxin Miao from the CAU presents the Chinese PI within this project.

June 2015: Lishu Research Site

Dr. Raj Khosla (Colorado State University, USA) visited the Lishu Research Site with Dr. Fei Yuan (Minnesota State University, USA) and Dr. Yuxin Miao (China Agricultural University) on June 8th and 9th, 2015. Lishu is a new ICASD research site for precision maize management research started in 2015.
Dr. Khosla gave a presentation on “Precision Management of Nutrients, Water & Seeds: A Holistic Approach” at the departmental seminar in the evening of June 9th, and also gave a presentation on “Climate Smart Precision Agriculture for Small Scale Farming Systems” at the Food Security Forum on June 10th.

ICASD field campaigns 2015

Starting in April, a new series of field measurements was conducted in
Quzhou, Hebei Province, China.

Crop growth in irrigated wheat fields of the Quzhou Experimental Station
(China Agricultural University, Beijing) is investigated.

From the University of Cologne (Germany), the former ICASD PhD student
Dr. Juliane Bendig and student assistant Lars Gruenhagen monitored crop growth
using an UAV (equipped with RGB and thermal sensors) and a field spectrometer.
