Effect of organic material input on the crush strength of seven granulated organo-mineral fertilisers
© European Compost Network ECN e.V. (6/2014)
Organo-mineral fertilisers (OMF) based on a judicious mix of both organic materials and mineral nitrogen (N) and phosphorus (P) plant nutrients play an important role in improving soil fertility and crop yield. However, the efficiency and reliability of OMF made from mixtures of separated solid fraction of pig slurry (SPS) and ammonium phosphate as alternative sources of N, P and organic amendments depends, among several factors, on the crush strength (CS) of OMF granules.

Regulating Ocean Fertilization under International Law: The Risks
© Lexxion Verlagsgesellschaft mbH (6/2013)
This paper explores the regulatory regime for ocean fertilization under the Dumping regime, which comprises the 1972 London Convention and 1996 Protocol. It assesses the extent to which ocean fertilization is presently subject to mandatory and voluntary controls and provides an overview of the proposals currently under active consideration designed to develop a comprehensive regime for ocean fertilization. Whilst acknowledging the benefits of regulation and the importance of environmental protection, this paper concludes with a warning against considering ocean fertilization in isolation from the broader context of geoengineering and climate change more generally.

Composting of Municipal Solid Waste in the districts of Lomé (Togo): experimental process study and agronomic use potential
© Wasteconsult international (5/2011)
This study concerns waste processing by composting in Lomé (Togo). It presents the composition of this waste, the treatment by composting of this waste recovered in the transfer sites and collected within individual households, an evaluation of its use as a fertilizer, and finally a market research to determine its economic value.

Micronutrients uptake by corn from Sewage sludge treated soils
© Aristotle University of Thessaloniki (6/2009)
In arid and some semiarid regions of Iran due to the shortage of organic matter,in soil, in one hand, and industrial production of organic fertilizers, on the other hand, the tendency toward the usage of sewage sludge (biosolid) has increased. Biosoild is rich in macro and micronutrients its application to the agricultural soils can promote growth and productivity of crops. One aspect of biosoild application as an organic fertilizer on agricultural farms is environmental pollution concerns such as heavy metals uptake by plans. The objectives of this research were to study the effect of biosolid applications (levels 0, 25, 50 Mg ha-1) to soils under corn plant.

Application of computer modelling for forecasting of contaminants distribution in soil
© Aristotle University of Thessaloniki (6/2009)
An outlook of various methods of computer modeling application for the analysis and forecasting of contaminants migration in the soil is being discussed. A new mathematical model of contaminants transport in near-surface soil layer under non-isothermal conditions is being proposed. The given model takes into account the soil moisture content change effecting the solute transport and sorption owing to evaporation processes and recondensation of water vapor. The article also covers the possibility of hybrid expert systems (HES) application for solving contaminants migration in the soil. Distinguish structure of HES that includes models hybridization is being proposed. On the basis of given methods and models a new software has been developed.

Prediction of nitrate leaching under different climatic and nitrogen management scenarios
© Aristotle University of Thessaloniki (6/2009)
Prediction of nitrate leaching by using dynamic simulation under different climatic and crop management scenarios is useful in designation strategies to reach agronomic and environmental goals. Nitrate leaching from maize and winter wheat stands on layered sandy and loam soil profiles was studied by simulation, using the Swedish Coupled heat and mass transfer model for soil-plantatmosphere systems (CoupModel).

Preliminary studies on the degradation of a range of pesticides in novel biomixtures using different agricultural by-products as straw substitutes
© Aristotle University of Thessaloniki (6/2009)
Five common ligninocellulosic materials with different physicochemical characteristics were used in novel biomixtures as straw substitutes. The biomixtures formed were treated with a mixture of 9 commonly used pesticides. The degradation of the pesticides as well as some biochemical parameters (total hydrolytic activity, substrate induced respiration, Mn peroxidase and Laccase activity) were measured during the experiment.

The FOOTPRINT software tools: Pesticide risk assessment and management in the EU at different spatial scales
© Aristotle University of Thessaloniki (6/2009)
In the EU-project FOOTPRINT three pesticide risk assessment and management tools were developed, for use at different spatial scales. The three FOOTPRINT tools share the same underlying science, based on the consistent identification of environmental characteristics driving the fate of agriculturally applied pesticides and their interpretation to parameterise state of the art modelling applications thus providing an integrated solution to pesticide risk assessment and management in the EU.

Fuzzy decision support system for assessing nitrogen fertilization in agricultural land
© Aristotle University of Thessaloniki (6/2009)
Modern conditional agriculture is based on whole field and mostly empirical approaches in defining and applying agrochemical inputs. The impact of fertilizing practices in the environment comprises of a crucial research matter. Soil nitrogen in its nitrate form is the most mobile nutrient, meaning that is easily leached out of soil system, increasing environmental risk.
