Studying soil-reclamation state of rice agricultural landscapes

Arsenic Tracking in Iranian Rice: Analysis of Agricultural Soil and Water, Unpolished Rice and White Rice

Since rice is a staple food most consumed world-wide, there have been increasing health concerns regarding exposure to arsenic through rice consumption. Several studies have reported the accumulation of arsenic in rice grains cultivated in regions with elevated levels of arsenic in groundwater or contaminated soil. Therefore the principal aim of this study was determining the amount of arsenic ...

Sodic soil reclamation: Modelling and field study

Reclamation of sodic soils has traditionally been undertaken using calculation of gypsum or Ca requirement assuming 100% exchange efficiency and neglect of the contribution of calcium carbonate in the profile. The UNSATCHEM model is reviewed and then evaluated for its ability to predict field reclamation of a sodic saline soil. The 40-ha field site was initially at an electrical conductivity (E...

Acoustic Observations in Agricultural Landscapes

Sounds emanating from various habitats and ecosystems provide a rich source of information to interpret ecological phenomena at multiple scales. Acoustic communication is a fundamental property of many animals for breeding and defending territories (Fletcher 1953, Peterson and Dorcas 1994), and acoustic signatures can be used to measure the spatial and temporal distributions of vocal organisms ...

Biochar for soil remediation and land reclamation

Land reclamation generally relates to the improvement of soils degraded by human activities, for example construction and certain forms of agriculture. Soil remediation refers to the process of removing, neutralizing or reducing the toxicity of certain compounds, often left by human activities such as mining and industry. Each degraded and/or contaminated site is potentially unique in its chara...
