Organic matter (OM) and pH may influence nanoparticle fate and effects in soil. This study investigated the influence of soil organic matter content and pH on the toxicity of ZnO-NP and ZnCl2 to Folsomia candida in four natural soils, having between 2.37% and 14.7% OM and [Formula: see text] levels between 5.0 and 6.8. Porewater Zn concentrations were much lower in ZnO-NP than in ZnCl2 spiked s...

Th e aim of the present study was to determine diff erences of amount and composition of milk between conventional and organic systems in Istrian pramenka breed of sheep. Sum of the data included 838 conventional and 9238 organic samples of eweś milk. Each farm is classifi ed as organic from the date of entering in organic production. Before that date farms didń t show characteristics of organi...

In this study, the nutritive values of treated Walnut hull by Neurospora sitophila were evaluated. The chemical composition of samples was evaluated by laboratory analysis.In vitrodigestibility experiment was done to determine digestibility coefficients of dry matter, organic matter and also digestible organic matter in dry matter (DOMD) to estimate the metabolizable energy (ME) content oftreat...

The main objective of this study was to compare the performance of two liquid organic fertilizers, an animal and a plant-based fertilizer, with mineral fertilization on citrus trees. The source of the fertilizer (mineral or organic) had significant effect in the nutritional status of the organic and conventionally managed mandarins. Nutrient uptake, vegetative growth, carbohydrate synthesis and...

Runoff leads to the leaching of soil nutrients, transports the topsoil particles and deposits the sediments in water reservoirs. Recognition of different environmental factors affecting the runoff properties and water infiltration depth has a great importance concerning soil for the integrated management of watershed and the distinguishment of complex hydrological processes. Thus, this research...

cation exchange capacity (cec) is one of the main factors in monitoring and management of soil quality in order to achieve sustainable production. although cec can be measured directly, these measurements are difficult, time-consuming and costly, especially for aridisols. one alternative method is the use of pedotransfer functions (ptf), in which cec of soils is estimated through available soil...

The aim of this work was to find the most useful inorganic nitrogen source to enable Leucopaxillus giganteus to become a more nutritious mushroom, regarding organic acid and phenolic composition and total alkaloids content. For these, the influence of NH 4NO 3,NaNO 2, KNO 3,, and (NH 4) 2HPO 4 on the organic acid production was determined by HPLC-UV and total alkaloid content was assessed by a ...

This study was conducted to evaluate the effects of dietary supplementation of protected organic acid blends including medium chain fatty acids and different nutrient density diets on growth performance, nutrient digestibility and faecal noxious gas content in growing pigs. A total of 80 crossed [(Landrace × Yorkshire) × Duroc] growing pigs with an initial body weight (BW) of 22.61 ± 2.32 kg we...

abstract in order to evaluate the effects of different organic and biological fertilizers on quantity and quality of essential oil of fennel an experiment was conducted in a completely randomized block design with three replications. the experimental treatments were two organic (compost and vermicompost) and two biological (pseudomonas putida and azotobacter chroococcum ) fertilizers, their all...
