During the 2013-2014 and 2014-2015 winter wheat growing seasons in the North China Plain, the effects of planting patterns and irrigation fre...
To study the effects of tillage system, planting method and of nitrogen fertilizer rate on the agronomic characteristics and seed yield of rapeseed (Brassica napus L.) Dalgan oilseed rape cultivar, as the second crop after rice, a split factorial experiment in complete randomized block design with three replications was carried out in two cropping seasons (2016-2018) at paddy fields of Rice Res...
Results We present global planting date patterns for maize, spring wheat and winter wheat (our full, publicly available data set contains planting and harvesting dates for 19 major crops). Maize planting in the northern mid-latitudes generally occurs in April and May. Daily average air temperatures are usually c. 12–17 °C at the time of maize planting in these regions, although soil moisture of...
After the mining of mineral resource, mineland resources utilization became increasingly complicated. Soil and planting information can be used as the indicators to evaluate mineland reclamation level. In order to obtain the soil and planting information in real time, a CDMA-based soil-quality monitoring system was developed to wirelessly monitor air/soil environment and plant image in remote o...
