A crop phenology model for Windows
An object oriented model for simulating crop and weed phenology under field conditions has been developed for educational and research purposes. The model can be used to study seasonal dynamics of crop and weed canopies which are important in controlling crop photosynthesis, evapotranspiration, …

Multi-temporal Remote Sensing of Changing Agricultural Land Uses within the Midwestern Corn Belt, 2001-2015
… use and management practices in recent decades. Cropland expansion, crop rotation change, and crop phenology changes could lead to divergent environmental impacts on linked ecosystems. The overall objective is to examine agricultural land use and management changes and their impacts on water …

Optical remote sensing for agriculture monitoring: a quantitative assessment under local conditions
… and reproducible information on the status of crops and soil across a wide range of spatial and temporal scales. This thesis develops a locally adapted yet scalable and transferable EO-based framework for the quantitative monitoring of agricultural land in Czechia, leveraging the complementary …

Polarimetric SAR for the monitoring of agricultural crops
The monitoring of agricultural crops is a matter of great importance. Remote sensing has been unanimously recognized as one of the most important techniques for agricultural crops monitoring. Within the framework of active remote sensing, the capabilities of the Synthetic Aperture Radar (SAR) to …

Crop monitoring and yield estimation using polarimetric SAR and optical satellite data in southwestern Ontario
… been proven as an efficient source to extract crop information and monitor crop growth conditions over large areas. In local- to subfield-scale crop monitoring studies, both high spatial resolution and high temporal resolution of the image data are important. However, the acquisition of optical …

Effect of summer and winter rotations on selected soil properties and productivity of succeeding winter chickpea (Cicer arietinum L.)
… (Cicer arietinum L.) is one of the minor pulse crops in South Africa, but there is hardly any commercial chickpea production in South Africa and the rest of Southern Africa despite its increasing domestic demand. The country meets its domestic demand through imports. Preliminary research has …

Quantifying Crop Yield, Bioenergy Production And Greenhouse Gas Emissions From Cropland And Marginal Land Using A Model-Data Fusion Approach
… maize (<em>Zea mays</em> L.)) and cellulosic crops (e.g., switchgrass (<em>Panicum virgatum</em> L.) and <em>Miscanthus</em> (<em>Miscanthus × giganteus</em>)) provides alternative energy to fossil fuels and has been considered to mitigate greenhouse gas emissions. To estimate the large-scale …

Evaluation and Application of the Community Land Model for Simulating Energy and Carbon Exchange in Agricultural Ecosystems
… (CMIP5), however, did not include process-based crop models with comprehensive physiology and phenology. One of the most widely used LSMs, the Community Land Model (CLM), has only recently included prognostic crops (CLM4-Crop). This thesis research evaluated the CLM4-Crop LSM for corn and soybean …
