Spatial Estimation of Soil Moisture and Salinity with Neural Kriging
The study was carried out with 107 measurements of volumetric soil water content (SWC) and electrical conductivity (EC) for soil profile (0-30 cm) and the estimating accuracy of ordinary kriging (OK) and back-propagation neural network (BPNN) was compared. The results showed that BPNN method predicted a slightly better accurate SWC than that of OK, but differences between both methods were not ...
متن کاملStudy of Changes in Soil Moisture and Salinity Under PlasticMulch and Drip Irrigation in Pistachio Trees
In this study, changes in soil moisture and salinity contents in drip irrigation combined with white and black plastic mulches compared to no mulch (control) was evaluated. The experiment was carried out in two commercial pistachio orchards (Ohadi cultivar) with irrigation frequencies of 8 to 12 days with a total water consumption 4100 and 6170 m3ha−1. The study was conducted in a complete rand...
متن کاملeffect of salinity on performance of smart sensors in determination of soil moisture content
the accuracy and effectiveness of precision agriculture is highly depending on accuracy and time analysis of the soil moisture conditions. monitoring of the soil water status is a proper method for optimizing the agricultural irrigation. automation irrigation, based on soil moisture measurement by smart sensors has the potential to provide maximum water use efficiency by maintaining soil moistu...
متن کاملWeight Measurements by Using Simple Optical-Fiber Sensors (RESEARCH NOTE)
The use of different optical-fiber sensors for weighing measurements is Abstract described. By using three different mechanical stressing mechanisms, the operation of the fiber-to-fiber transducer systems are tested and the results are presented. Parameters such as sensitivity, hysteresis, resolution, and dynamic range are measured. A comparison of the results has shown that the sensor system m...
متن کاملcorrection of gypsum block readings due to salinity effects for soil moisture content measurements
abstract irrigation planning and management requires continious monitoring and measurements of soil moisture content. application of gypsum blockes (gb) are common in soil moisture measurements. gb readings are subjected to its geometry and soil solution concentration. this study was carried on 90 gb in research greenhouse of faculty agricultural, ferdowsi university of mashhad. at the begining...
