A prerequisite to use organic fertilizers in a sustainable way is to quantify the amount of phosphorus and potassium available for plants that could be taken up by a crop. The objective of this study was to evaluate direct and subsequent influence of organic fertilizers addition (poultry manure and two types of composts) on the changes of bioavailability of phosphorus and potassium in soil and ...

Understanding the diversity and community structure of arbuscular mycorrhizal fungi (AMF) is important for potentially optimizing their role in mining phosphorus (P) in agricultural ecosystems. Here, we conduct a comprehensive study to investigate the vertical distribution of AMF in a calcareous field and their temporal structure in maize-roots with fertilizer P application over a three-year pe...

Twentyfour surface soil samples (0-30 cm) collected from salt affected area of Vasantdada Sugarcane Research and Development farm Manjari(Bkk.), Pune, Maharashtra (India) were studied for the Cu, Zn, Fe and Mn status in relation to important soil factors. All the soil samples had adequate amount of Cu, Zn, Fe and Mn. Iron and Maganese are significantly positively correlated with organic carbon,...

background: previous studies have demonstrated that patients with insulin-dependent diabetes mellitus (iddm) have a high prevalence of osteopenia.  hypercalciuria has also been well documented in human diabetes and many children with insulin-dependent diabetes mellitus have short stature.   objective: to investigate the relationship of hypercalciuria and hyperphosphaturia with growth retardatio...

In sub-Saharan Africa, crops are often grown under low nitrogen (N) and phosphorus (P) conditions, which may impact on the nutritional components of grains. The aim this study was to investigate effect N P a combination two iron (Fe), zinc (Zn) phytic acid content in commercial South African spring wheat cultivars (PAN3497 SST806). Phenotypic traits were also investigated. Although cultivar eff...
