Understanding microtopography changes in agricultural landscapes through precision assessments of digital surface models by the UAV-RTK-PPK method without ground control points

Autor: Yasutaka Nakata, Kenta Iwasaki, Seiji Shimoda, Hiroyuki Torita

Publikováno v: Smart Agricultural Technology, Vol 5, Iss , Pp 100269- (2023)

Soil erosion on agricultural land causes severe environmental problems and damages crop plants. Structure-from-motion with multiview stereo (SfM-MVS) together with data obtained via unmanned aerial vehicles (UAVs) helps understand spatiotemporal chan

An improved crop calendar model for winter wheat incorporating vernalization and winter survival to project changes in phenology

Autor: Keach Murakami, Toshichika Iizumi, Seiji Shimoda

Publikováno v: Environmental Research: Food Systems, Vol 1, Iss 1, p 011002 (2024)

Crop phenology and associated crop calendars are necessary for designing breeding goals and for developing effective management practices. Winter wheat is a representative biennial, the cultivation schedule of which is constrained by winter climate c

Prediction of municipality-level winter wheat yield based on meteorological data using machine learning in Hokkaido, Japan

Autor: Keach Murakami, Seiji Shimoda, Yasuhiro Kominami, Manabu Nemoto, Satoshi Inoue

Publikováno v: PLoS ONE, Vol 16, Iss 10 (2021)

This study analyzed meteorological constraints on winter wheat yield in the northern Japanese island, Hokkaido, and developed a machine learning model to predict municipality-level yields from meteorological data. Compared to most wheat producing are
