AbstractIn agricultural culture there are numerous weeds diminishing the production which are controlled by several methods. The most common and efficient method with the modern agriculture is the chemical method of controlling weeds, using a large range of herbicides. A great part of these herbicides have long lasting remanence, even over three years. A great part of the active substances of the herbicides pollute the soil and subsequently the waters, sometimes with disastrous action for the en...

It was revealed that available techniques for soil decontamination can be divided in two parts, depending on where the action have place: in-situ or ex-situ. Also, depending on the nature of the process, these techniques can be biological, physical-chemical and thermal. In order to decontaminate soils properly, the primary contaminants ...

Maize (Zea mays L.) is considered one of the most popular grain crops in China. Among various agricultural technologies, soil mulching is the one that is used more and more in recent years. Mulches influence the soil temperature, retard the loss of soil water, and limit the growth of weeds; and these are important factors in the production of maize. A two-year field experiment was carried out at Shanghai, in southeast of China, in order to evaluate the effects of water hyacinth residues as mulch...

Overexploitation and competitiveness over shared fresh water resources are some of the growing problems that affect numerous countries world-wide, in particular those characterized by high water-related risks linked to water scarcity, droughts and baseline water stress. Private and public sectors are driven to find alternative or best-practice strategies to conserve and optimize the water resource and guarantee a future use to all. The affiliate of Philip Morris Manufacturing and Technology Bol...

Water supply represents a constant worldwide challenge for people and authorities. This issue is significantly severe in semiarid regions such as Gaza Strip, where groundwater constitutes the only fresh water source. Furthermore, Gaza Strip area suffers from water scarcity due to the decrease in water recharge and a constantly groundwater over-pumping, along with seawater intrusion, which cause serious problems in fresh water supply. Treated wastewater reuse represents a sustainable approach to...

Space exploration requires reliable, rapid, significant and safe methods for preventing, monitoring and controlling biocontamination risk in water loops and humid areas in manned Space habitats. Water is one of the most important resources of our everyday life. Its microbiological control in houses, public water dispensers and special conditions (e.g.: epidemics, catastrophes, isolation) is crucial. The presented solution is automated, compact and portable, and above all “integrated&rdquo...

Citrus is one of the most important fruit tree crops worldwide, with respect to both total production and economic value. About 80% of the world production is destined to the fresh market, the remaining is processed to obtain various products (juices, jams, etc.). Citrus processing residues account for about 50-60% of processed fruits; their huge amounts and peculiar characteristics need a correct management that imply cost for producers and processors. If not well managed, they can represent an...

A significant reduction in nitrogen (N) losses from agricultural fields will make a positive impact on the environment. Managing nitrogen for the optimum application provides economic benefits as well as environmental protection. This study presents a model that was developed to determine the optimum ratio of N to yield based on N sensor indices in winter wheat. A quadratic polynomial model was used to characterize the relationship between N and yield for the optimum N rate. The N was applied t...

The concentrations of Copper (Cu), cadmium (Cd), manganese (Mn) and lead (Pb) in liver, kidneys and red meat of cattle slaughtered in selected abattoirs in Owerri metropolis, Nigeria were studied using atomic absorption spectroscopy (AAS). This was performed in relation to their concentrations in a forage grass, Panicum maximum randomly harvested from roadsides of Owerri- Onitsha and Owerri-Aba expressways. Results obtained showed that cattle meat samples contained all heavy metals studied. Thei...

Transport networks, including highways, have many negative ecological impacts, such as habitat loss and landscape fragmentation. One of the most consicuous negative effects is wildlife vehicle collision (WVC). The basic aims of this study, conducted on the KÄąrÄąkkale-ÇankÄąrÄą Highway, Turkey, are the following: i) identifying locations of WVC events, ii) modeling the effects of landscape pattern and traffic characteristics on WVC and iii) proposing a solution to mitigate WVC. In the st...

Côte d'Ivoire is one of the world's leading producers and exporters of agricultural products. Unfortunately, the multiplicity of stakeholders in this sector and the absence of legislation and regulations have contributed to the pollution of the various hydro systems, particularly those of Taabo river basin. The purpose of this study was to assess the ability of the Soil and Water Assessment Tool (SWAT) model to test the applicability of three vegetative filter strips scenarios to m...

This study was performed to quantify the effects of land use changes resulting from the construction of Karkheh Dam, in southwest of Iran, on the water quality of Karkheh River. For this purpose, the periodical Landsat TM and ETM+ images were used to assess the changing trends of the land use types before and after the dam construction. The water quality data were collected from the hydrometric stations and the possible correlation between the changes in the land use types and water quality par...
