Rice Cultivation on Reducing Excessive Soil Fertility and Rice Growth in Continuous Vegetable Cropped Greenhouse Soil

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 ...

Soil fertility in flooded and non-flooded irrigated rice systems

Long-term rice cultivation stabilizes soil organic carbon and promotes soil microbial activity in a salt marsh derived soil chronosequence

Soil organic carbon (SOC) sequestration with enhanced stable carbon storage has been widely accepted as a very important ecosystem property. Yet, the link between carbon stability and bio-activity for ecosystem functioning with OC accumulation in field soils has not been characterized. We assessed the changes in microbial activity versus carbon stability along a paddy soil chronosequence shifti...

Effects of Residue Decomposition on Productivity and Soil Fertility in Rice–Wheat Rotation

containing about 1.90 million Mg of nutrients, are available in the IGP of India (Sarkar et al., 1999). In the Rice (Oryza sativa L.)–wheat (Triticum aestivum L.) farmers in Indian Punjab alone, about 12 million Mg of rice straw India burn or remove residues to facilitate seedbed preparation. Incorare burned annually, which causes about 0.7 million Mg poration of residues before planting of the...

Effect of rice straw and wood chips on Soil erosion and seedling growth on the fill slope of forest roads

Extended abstract   1-Introduction Erosion is a geomorphologic and natural process that is always seen across the world, but this process is triggered by human activities, such as road construction, resulting in a significant negative impact on water resources, soil, environment and national economy. According to the above, preventing soil erosion is an important target in the management and...
