Approximately 15 percent of Sweden’s land area is covered by peat ( 30 cm deep). In drained peatlands, decomposition of the peat produces greenhouse gases such as CO2 and N2O. Electric conductivity, measured with the instrument EM38, can be used to assess spatial variation in soil properties. To easier decide the quantity of the CO2-emissions from a peatland the possible relation between electr...

Flood irrigation is often applied in the arid regions of Northwest China to facilitate leaching salts accumulated soil during cotton growth previous season. This will, turn, affect temporal and spatial patterns salinity, thus germination. To reveal salinity two layers (0–20 cm 20–60 cm), so as determine optimal sowing timing, an electronic ground conductivity meter (EM38-MK2) was employed measu...

Precision agriculture is experiencing substantial development through the improved availability of cost-effective instruments for data collection. This includes ground-based proximal sensing technologies that are able to compete with satellite and aircraft observation systems, due low operational costs, high flexibility, spatial resolution. article was therefore designed compare performance mul...

Quantification of drainage to remove excess water from the soil profile and provide a suitable environment for vegetation has been developed over the years. Drainage estimation is fairly challenging particularly in the heterogeneous urban environs. This research studied the temporal variation of drainage rate and nutrient leaching in Veale Gardens of Adelaide Parklands, Australia. A zero tensio...

Diagnosis of soil salinity and its spatial variability is required to establish control measures in irrigated agriculture. This article shows the usefulness of electromagnetic (EM) and soil sampling techniques to map salinity. We analysed the salinity of a 1-ha plot of surface-irrigated olive plantation in Aragon, NE Spain, by measuring the electrical conductivity of the saturation extract (ECe...
