this study was done with the aim of investigating the kinetics of available phosphorus changes in treated soils with municipal solid waste compost, fertilizer and the mixture of these in two levels of first and second percent in eight calcareous soil samples and in a period of zero to 3600 hours in incubation conditions (fc moisture and 250c). the results showed that with time increasing, extra...

Phosphorus (P) and suspended sediment (SS) play a pivotal role in influencing water quality and biodiversity and, as a result, controlling the transfer of these important diffuse pollutants from land to water, represents a priority task for catchment managers and stakeholders (Kronvang et al., 2005a). This review briefly summarises the environmental and legislative context regarding phosphorus ...

Maize is one of the important cereal crops in the world agricultural economy both as food grains for human and fodder and feed for cattle and poultry. Maize grain contains about 72% starch, 10% protein, 4.8% oil, 5.8% fiber, 3.0% sugar and 1.7% ash (Choudhary, 1993). Along with this, it is rich in vitamin A, vitamin E, nicotinic acid, riboflavin and contains fairly high phosphorus than rice and...

We perform classical molecular dynamics simulations to investigate the effects of mechanical strain on single-layer black phosphorus nanoresonators at different temperatures. We find that the resonant frequency is highly anisotropic in black phosphorus due to its intrinsic puckered configuration, and that the quality factor in the armchair direction is higher than in the zigzag direction at roo...

In recent decades, degradation of ecosystem in the steppe region of the Inner Mongolia Plateau, especially in riparian floodplain wetlands, has become a significant ecological crisis. Not uncommonly, with the increasing of livestock in the Inner Mongolian steppe region, a riparian floodplain wetland is becoming a hotspot area of grazing for local herdsmen. Hence, it is essential to understand d...

introduction phosphorus (p) is an essential element in crop nutrition, which can be growth limiting or an environmental contaminant, if present in excess. on the other hand, tillage practices have a direct effect on behavior and availability of soil p. since, application of different tillage methods lead to different patterns of soil phosphorus distribution, hence p fertilizer needs and p avail...

Large unilamellar liposomes and multilamellar vesicles consisting of DMPC interacted with cationic phosphorus-containing dendrimers CPDs G3 and G4. DSC and ζ -potential measurements have shown that liposomal-dendrimeric molecular recognition occurs due to the interaction between the complementary surface groups. Calorimetric studies indicate that the enthalpy of the transition of the lipids tha...
