A greenhouse experiment was conducted using corn to study the effect of arbuscular mycorrhiza, organic matter and zinc (Zn) on chemical forms of Zn in a calcareous soil. Experimental setup was factorial, based on completely randomized design with 3 replications. Treatments consisted of 3 levels of Zn (0, 5, and 10 mg Zn per kg soil), 2 kinds of organic manure (sheep manure and municipal waste c...

Three competing mathematical fitting models (a point-by-point estimation method, a linear fit method, and an isoconversion method) of chemical stability (related substance growth) when using high temperature data to predict room temperature shelf-life were employed in a detailed comparison. In each case, complex degradant formation behavior was analyzed by both exponential and linear forms of t...

Application of sewage sludge on the farmland as a source of crop nutrient had recently received considerable attention. Some management practices may be required to control the accumulation of toxic elements including Pb, Ni and Cd. Sequential extraction gives useful information on plant bioavailability of the elements. The objective of this study was to investigate the cumulative and residual ...
