Cropping systems information on explicit scales is an important but rarely available variable in many crops modeling routines and of utmost importance for understanding pests and disease propagation mechanisms in agro-ecological landscapes. In this study, high spatial and temporal resolution RapidEye bio-temporal data were utilized within a novel 2-step hierarchical random forest (RF) classific...

In the present study, 3 replanted black pepper orchards with continuously cropping histories for 10, 21, and 55 years in tropical China, were selected for investigating the effect of monoculture on soil physiochemical properties, enzyme activities, bacterial abundance, and bacterial community structures. Results showed long-term continuous cropping led to a significant decline in soil pH, organ...

The continuous cropping of cucumber in the same potting soils may result in a reduction of yield and quality of the crop, a phenomenon described as soil sickness. The changes of soil microbial communities as affected by continuous cropping and the link between these changes and soil sickness of cucumber are still not clear. In the present study, cucumber was cropped in pots under greenhouse con...

Soil degradation has been a very serious problem for sustainable production, especially by a re-cropping of greenhouse-cultivated cucumber (Cucumis statirus L.). The aim of this research was to expound the actuality for soil degradation, at the same time, put forward some suggestion for preventing from soil degradation and maintain sustainable production in greenhouse basic on the two experimen...

Hairy vetch (Vicia sativa L.) succeeded by corn (Zea mays L.)or grain sorghum (Sorghumbicolor L. Moench) were seeded insplit plots randomized within whole plots of no-tillage versus conventional tillage over four growing seasons (1980-83). The vetch-corn cropping system increased the density of Meloidogyne incognita 2.9 X more than the vetch-grain sorghum cropping system. I n contrast, the vetc...

Steganography is the art and science of hiding or embedding data in a transmission medium. The goal of steganography is to hide an information message inside a harmless cover medium in such a way that it is not possible even to detect that there is a secret message. In this paper, the object oriented steganography is based on biometrics. Data is embedded into some regions of the skin and not to...

Automatic image cropping algorithms aim to recompose images like human-being photographers by generating the boxes with improved composition quality. Cropping box regression approaches learn beauty of from annotated boxes. However, bias annotations leads quasi-trivial recomposing results, which has an obvious tendency average location training samples. The crux this predicament is that task nai...
