After cultural treatments such as site preparation, release and fertilization, changes in the supply of mineral nutrients relative to each other and shifts in the composition of vegetation may have a delayed effect on the nutrition, carbon partitioning and growth of forest trees. This study was conducted to evaluate the influence of early management options that control vegetation and fertility...

During an epidemiological survey on the relationship between diet and cardiovascular risk factors, serum sodium, potassium, calcium, phosphorus, and total protein were measured in 4167 men and 3891 women with a mean age of 49 years. Several consistent and highly significant correlations were found between serum cation and phosphorus levels and blood pressure. The analysis was performed separate...

The mineral compositions of the 8 wild edible fruits were investigated. Nitrogen, sodium, potassium, calcium, magnesium and phosphorus were analyzed as the major constituents of the fruits and iron, zinc, copper and manganese were identified as a minor constituent. Among all the mineral, Potassium were found in large quantity in all fruits. Ficus racemosa L., fruit contain the highest amount of...

This study was designed to investigate the effects of different tillage systems on some parameters such as soil salinity (pH, EC, SAR), soil density and nutrients in a nested experimental design with three treatments (no tillage, reduced tillage and conventional tillage) and three replications. Chenaran city fields were selected as the case study areas. Result of the statistical analysis indica...

This paper took the wheat field of typical alluvial soil area as the research site, aimed to explore the spatial pattern of the soil nutrients, such as soil available potassium, soil available phosphorus, soil organic matter (SOM) and soil alkali hydrolysable nitrogen. With the help of DGPS, a total of 104 topsoil(0–20cm) samples were collected. Based on classical statistics, research results i...
