Cassava is a staple food and major source of income for many smallholder farmers. However, its yields are less than 6 t ha−1 compared to potential yield 20–25 in Zambia. Understanding cropping practices constraints cassava production systems imperative sustainable intensification. Therefore, survey 40 households each with three fields at 12, 24, 36 months after planting (MAP) was conducted. Ana...

the aim of this research was to evaluate some soil physical quality indicators using remotely sensed date, gis and geostatistical methods in baft area that is one of the most important centers of agricultural production in kerman province. therefore, soil samples were collected from 0 to 20cm depth of 183 points based on regular sampling pattern (every 250 meters) and soil physical indicators i...

Geostatistics provides quantitative indicators to characterize the spatial distribution of soil attributes which follow the regionalized variable theory. The present study aimed at applying Geostatistics to enhance the resolution of a regional soil map at East El-Owienat area which surveyed by one profile for each four kilometers. Studied area was extracted over 71 thousand feddans where six so...

Ground response analyses are mostly used for the development of design response spectra in the modern earthquake engineering. After 1999 Marmara Earthquake, the damages were mostly related with unavailable soil conditions and this unavailability were analysed according to liquefaction analysis. The other analyses which cover the dynamic soil properties were not studied in detail. In this study,...

zygophyllum atriplicoides is one of the most important rangeland plants that often seen as associated species and rarely seen as the dominant species in ranglands rangelands which is very critical for soil  in starting and ending points of each transect. measured soil properties (included gravel, texture, organic matter, lime, ph and electrical conductivity) and physiography (elevation and slop...

of stereoscopic landscape analysis, and then determine the soil types that occur in each map unit by field inspecA method to enhance manual landform delineation using phototion of the soil at representative sites. A common inspecinterpretation to map a larger area is described. Conventional aerial tion density is one observation per one to four map photo-interpretation (API) maps using a geo-pe...

this research was done in order to submit a model for salinity map made with tm satellite data and salinity values in a buienzahra. the necessary processings such as principal component analysis and producing of different indices was done on the main bands. the 38 soil samples using random sampling (with 10×10 km dimension) from different horizons were designed and performed on the study area. ...
