Since the remote sensing data of MODIS has some advantages of short detection period, wide coverage and open access, it is suitable for large-scale, dynamic agricultural remote sensing monitoring. According to the application requirements of winter wheat acreage extracting in Huang-Huai region, this article analyzes the features of MODIS data and phenological characteristics of crops. Three kin...

The Florida vegetable industry relies heavily on plasticulture technologies from the transplant nursery through the packing house and market chain. The value of the Florida vegetable industry has consistently risen while the acreage has declined for many commodities. The use of greenhouse technologies for high-valued crops is an alternative method of crop production that would compliment the cu...

The objective of this study was to obtain up-to-date information on land use and to identify long term changes in land use, especially rice, aquaculture and other crops in Ben Tre and Tra Vinh provinces in Vietnam’s Mekong Delta. Long-term changes in land-use of the study area have not been studied using long time series of SAR and optical Earth observation (EO) data before. EO data from 1979–2...

Supplementary Information Data Notes-Soil Quality USDA-NRCS's soil surveys are conducted at pre-designated spatial units, known as map units (MUs), which represent common management requirements towards various land uses (Soil Data Viewer 6.0 User Guide, 2011 pp. 11). Although MUs are the finest spatial resolution in the soil surveys, they are composed of multiple map unit components that are h...

A major share of the area of hypoxic growth in the Northern Gulf of Mexico has been attributed to nutrient run-off from agricultural fields, but no estimate is available for the cost of reducing Gulf hypoxic area using agricultural conservation practices. We apply the Soil and Water Assessment Tool using observed daily weather to simulate the reduction in nitrogen loading in the Upper Mississip...

Rice acreage estimation is a key aspect to guarantee food security and also important to support government agricultural subsidy system. In this paper, we explored a sophisticated method to improve rice estimation accuracy at county scale and we developed our approach with China Environment Satellite HJ-1A/B data in Hunan Province, a fragmented area with complex rice cropping patterns. Our appr...

32 RRJBS| Plant Biotechnology and its ApplicationsS3, 2016 The world wheat production has to be doubled until 2050 to meet the increased demand arising from the continuing population growth, rising meat and dairy consumption, and expanding use of biofuel and biogas [1]. The most sustainable and environmental friendly approach to reach this goal is to increase crop yields per area, but yield gro...
