19th World Congress of Soil Science Congress Symposium 5 Micronutrients in soils and plants in relation to crop and human health

چکیده
The micronutrient density of seeds is important not only for human nutrition but also for the nutrition of the next generation seedling. Deficiencies of zinc (Zn), iron (Fe) and manganese (Mn) in soils and crops occur nearly in all countries, particularly in cereals growing areas. The deficiencies adversely affect both food production and human health in a major part of the world. Therefore, variations in micronutrient (Zn, Fe and Mn) accumulation were evaluated among 14 wheat varieties in a field containing DTPA extractable Zn, Fe and Mn 1.60, 17.55 and 3.50 mg/kg soil, respectively at the Research Farm, CCS HAU, Hisar, Haryana, India during 2008-09 The treatments for Zn, Fe and Mn consisted of control, 50% of the recommended dose, recommended dose, 150% of the recommended and recommended foliar spray. There is considerable genetic variation in concentration of Zn, Fe and Mn among all the wheat varieties. The accumulation of Zn, Fe and Mn were more in straw than seed, irrespective of the variety under study.

Forensic Taphonomy aims to provide information relevant to the courts in cases where cadavers have been allowed to decompose. Here I consider the cadaver’s effects on the burial environment when decomposition occurs on the soil surface or belowground. Significant advances have been made in recent years that have allowed a better understanding of cadaver decomposition, its effect on the burial e...
