Inorganic nitrogen (N) fertilizers, microbial inoculum and biologically-active substances are used to fortify composts which characteristically contain low amounts of N. The potentials organic wastes from agriculture for N enrichment were indicated by significant increase in soil while there can be fortuitous improvement the available phosphorus (P) contents on information about extent is lacki...

Introducing smart and sustainable tools for climate change adaptation mitigation is a major need to support agriculture’s productivity potential. We assessed the effects of processed gypsum seed dressing SOP® COCUS MAIZE+ (SCM), combined with gradient N fertilization rates (i.e., 0%, 70% equal 160 kg ha?1, 100% 230 ha?1) in maize (Zea mays L.), on: (i) grain yield, (ii) root length density (RLD...

In order to investigate the persistence of organic amendments, nitrogen and zinc effects on soil characteristics in rapeseed-wheat rotation, a factor analysis was conducted in a complete random design with three replications in two consecutive years in a greenhouse. Treatments in the first year consisted of N fertilizer, municipal waste compost, vermicompost, sheep manure. The control consisted...

Although classical density functional theory provides reliable predictions for the static properties of simple equilibrium fluids under confinement, a theory of comparative accuracy for the transport coefficients has yet to emerge. Nonetheless, there is evidence that knowledge of how confinement modifies static behavior can aid in forecasting dynamics. Specifically, recent molecular simulation ...

Much reusable software is available for solving routine mathematical and statistical problems. Unfortunately, locating this software is often quite diicult in current distributed computing environments. The Guide to Available Mathematical Software (GAMS) virtual software repository seeks to remedy this by providing users with convenient access to thousands of software modules physically distrib...
