organic matter and its related soil properties are among the most important indicators of soil quality. despite the importance of soil organic carbon, no comprehensive study has been done on organic carbon changes in soils of the isfahan province. the objective of this research was to investigate factors affecting soil organic carbon in soils of this province. a total of 248 surface soil sample...

Soil salinization has been known as a world wide problem. It is a chemical process that causes soil degradation particularly in arid and semi-arid agriculture region. There both advantages and disadvantages of optical and microwave remote sensing in the recognition of salinization soil. In order to retrieve both soil salinity and moisture, an empirical method is presented in this paper which is...

because of the scarcity of in situ measurements, estimation of soil temperature by other means is very indispensable, as for irrigation management and scheduling when in different field conditions. so far, many regression models have been developed for an estimation of soil temperature, using meteorological data under bare soil. throughout this study, the performance of coup simulation model an...

this study was conducted to determine regression equations for the prediction metabolizable energy value corrected for zero nitrogen retention (amen) in 12 wheat cultivars (mahdavi, chamran, sabalan, sepahan, sivand, alamoot, sholeh, neishaboor, pishtaz, bahar, shiraz and shahpasand) cultured in alborz province of iran. chromic oxide marker bioassay was used to determine wheat cultivars nitroge...

This present study explores the use high-resolution multi-spectral remote sensing data for generating within-field soil variability map as an inputs required for site-specific management of agriculture. The study was conducted for an experimental plot in Central Potato Research Station of Jalandhar, India. Thirty-five soil samples were collected from the field at regular intervals. The samples ...
