Determination of soil properties is based on soil sampling with low resolution (1- 2 or more samples per hectare) and their analysis in the laboratory. This method does not provide sufficient data to highlight the significant variability of the soil properties for the analysed parcel. This leads to a uniform distribution of the nutrients that can also be synthetic chemical substances (pollutants). Since the soil properties can influence plants growth, high-resolution mapping is required by the help of some sensors...

The paper compares the different description of drought periods in the history of annual rainfall in certain geographical areas. Drought indices are indispensable tools in detecting, monitoring and assessing drought events. These indices include: the Palmer drought index or drought severity index, PDSI abbreviated, Keetch-Byram drought index, KBDI abbreviation, drought recognition or recall index, abbreviated RDI, percentage of normal amount (average value for over 30 years), standardized precipitation index, SPI,...

The use of synthesis chemical substances in agriculture for increasing agricultural production and ensuring food across the globe is a process that has as a reverse negative effects on the environment and human health. According to the research conducted widely it has proved that, these synthesis substances that sometimes are toxic (pesticides, herbicides, etc.) have a negative influence on human health ultimately, also by polluting the environment, which represents the biggest challenge of the humanity today - cl...
