There is increasing concern about the sustainability and environmental impacts of mineral fertilizer use in agriculture. Increased recycling of nutrients via the use of animal and green manures and fertilizers made from domestic organic waste may reduce reliance on mineral fertilizers. However, the relative availability of nutrients (especially nitrogen) is lower in organic compared to mineral ...

A number of years ago, [Bro05] explored a prospective language feature then known as Object Templates. That feature died on the vine due to healthy skepticism voiced by EWG, as well as the usual lack of cycles to develop the idea much further. However, the original underlying issue is still present in C++11, after even many additional years of experimental effort to achieve the desired effect v...

Human health risks associated with the consumption of three shellfish (<i>Penaeus monodon, Crassostrea rhizophorae</i>, and <i>Tympanostomus fuscatus</i>) harvested from Buguma, Krakrama, Bonny Rivers in Niger Delta region were evaluated this study. The bioaccumulation potential toxic elements (PTEs) [Arsenic (As), Cadmium (Cd), Chromium (Cr), Lead (Pb), Nickel (Ni)] was...

Repeated fertilizer applications to cultivated soils may alter the composition and activities of microbial communities in terrestrial agro-ecosystems. In this study, we investigated the effects of different long term fertilization practices (control (CK), three levels of mineral fertilizer (N1P1K1, N2P2K2, and N3P3K3), and organic manure (OM)) on soil environmental variables and microbial commu...

BACKGROUND The aim of this study was to evaluate the effects of nitroxin biofertilizer and chemical fertilizer on the growth, yield, and essential oil composition of dill. The experiment was conducted under field condition in randomized complete block design with three replications and two factors. RESULTS The first factor was the concentrations of nitroxin biofertilizer (0%, 50%, and 100%) o...

The study was conducted to determine the interactive effects of biochar application in combination with farm yard manure (FYM) and nitrogen (N) fertilizer on soil organic matter (SOM) and mineral nitrogen at Agricultural Research Farm of Khyber Pakhtunkhwa Agricultural University Peshawar in 2010-2011. Soil samples at 0-15 cm depth were collected from maize and mungbean plots at harvest stage (...

Fluorescence and confocal laser scanning microscopy were explored to investigate the movement and localization of mineral oils in citrus. In a laboratory experiment, fluorescence microscopy observation indicated that when a 'narrow' distillation fraction of an nC23 horticultural mineral oil was applied to adaxial and opposing abaxial leaf surfaces of potted orange [Citrus x aurantium L. (Sapind...

of plant residue C and N. Application of 15N-labeled fertilizer or maize residue together resulted in more than The role of mineral fertilizer-N inputs and N deposition to agricultwice as much 15N recovered from fertilizer than from tural and natural ecosystems can affect plant residue decomposition and soil C processes. Yet it is still unclear whether residue-N or residue in the SOM (Dourado-N...

Effects of different fertilizers on organic carbon (C) storage and turnover of soil fractions remains unclear. We combined soil fractionation with isotope analyses to examine soil organic carbon (SOC) dynamics after 25 years of fertilization. Five types of soil samples including the initial level (CK) and four fertilization treatments (inorganic nitrogen fertilizer, N; balanced inorganic fertil...
