The non-uniformity of distribution of seeds sown in a row influences their productivity. To analyse and eliminate the causes of non-uniformities, the straight motion of coulters must be separated fr...
Satellite measurements for atmospheric pollutants monitoring provide full mapping, large spatial coverage, and high spatial resolution. Retrieved aerosol optical depth (AOD) from satellite data as t...
The vegetation coverage is one of the important factors that restrict the accuracy of remote sensing retrieval of soil moisture. In order to effectively improve the accuracy of the remote sensing re...
Billions of people in the world depend on rice as a staple food and as an income-generating crop. Asia is the leader in rice cultivation and it is necessary to maintain an up-to-date rice-related dat...
Rice is the most important cereal crop governing food security in Asia. Reliable and regular information on the area under rice production is the basis of policy decisions related to imports, export...
The monitoring was based on 6 localities selected from within different regions of the Czech Republic. The vegetation was monitored during 2005 to 2008. Plant checklists have been made for each locali...
Astragalus excapus L. and Astragalus austriacus Jacq. are regarded as critically endangered species in Slovakia. They are threatened by environmental impact, natural succession, as well as by human ac...
Altogether, 17 threatened wild plant species of the family Fabaceae, selected in their natural localities, were included in the monitoring. They could have prospects for use in agriculture or horticul...
The effects of elevated CO2 (approximate doubling of atmospheric CO2 concentration) on the rate of photosynthesis estimated from continuous monitoring of CO2 exchange in whole plants were investigated...
A two-band digital imaging system —one band for the visible red band (RED, 630−670 nm) and the other for the near infrared band (NIR, 820−900 nm)— was devised and positioned at a height of...
Procedures have been presented to utilize a yield-monitoring combine for test cultivations of paddy rice. As an example, grain yields were compared at two blocks of sparse (30cm×30cm) and controlled (...
