Predicting the soil fragmentation caused by grazing using adaptive neuro-fuzzy inference system (ANFIS)

Zhila Ghorbani; Kiomars Sefidi; Farshad Keivan Behjou; Mehdi Moameri; Ali Ashraf Soltani Tolarod

Volume 72, Issue 2 , September 2019, , Pages 557-568


  The most current way for measuring the soil fragmentation is determination of mean weight diameter (MWD). In this study, the adaptive neuro-fuzzy inference system (ANFIS) was used to predict of range soil fragmentation affected by different grazing intensities, distance from village and sampling depth. ...  Read More

Investigation the causes of uncertainty in methods for estimating soil organic carbon storage

isa Jafari Foutami; Esmaeil Sheidai Karkaj

Volume 71, Issue 1 , June 2018, , Pages 61-71


  The purpose of this study was to investigate the causes of uncertainty in different methods of estimating soil carbon and also to evaluate the proposed computational method that eliminated the effect of soil bulk density on carbon calculation and the actual soil carbon content for soils with different ...  Read More

Carbon and nitrogen allocation in aerial and underground organ of Artemisia austriaca Jacq. in different grazing intensities (Case study: Sabalan Darvishchae Rangelands)

Maryam Asadi

Volume 70, Issue 4 , January 2018, , Pages 895-908


  In this research, was investigated the effect of grazing intensities on carbon and nitrogen allocation in aerial and belowground biomass of Artemisia austriaca in summer rangelands of Darvishchae (including Alvares, Aldeshin and Asbmarz villages) at southern slope of Sabalan. The study areas based on ...  Read More
