Most producers use herbicides to manage weed infestations. Generally, herbicides are applied at a uniform rate to the entire field. However, a uniform application may not be appropriate for all areas of a field. As precision agriculture technologies have developed, site-specific management of most agricultural inputs, including herbicides, has become feasible. Differentiated application of herb...

Swine manure is generally used as fertilizer and applied to fields for growing agricultural commodities. Salmonella and other pathogens have frequently been isolated from swine wastes.1-3 Land application of Salmonella-contaminated manure may pose an environmental risk if movement occurs to surface and groundwaters.4-6 Sustainable swine production requires the development of innovative and cost...

Most often, our waterways are being polluted by municipal, agricultural and industrial wastes. When this happens, much of the available dissolved oxygen is consumed by aerobic bacteria in decomposing the waste, thereby robbing other aquatic organisms of the oxygen they need to live. In this paper, we consider the solution of the optimal control problem for the modified Dissolve Oxygen(DO)/ Biol...

The recycling and separation of waste from the source could reduce the amount of unusable waste. Workers in this sector are exposed to severe health complications. The present study aimed to assess the health status of waste recycling workshops in Jouybar and Ghaemshahr, Iran in 2018. In this descriptive, cross-sectional study, data were collected using a researcher-made questionnaire, the reli...

Urban agriculture (UA) is practiced inside (intraurban) or on the outskirts (periurban) of a town or a city. While it focuses on raising food and animal crops, it includes recycling household waste and wastewater for agricultural purposes, the processing and distribution of different food and non-food products using human and material resources, products, and services that are found in the same...

Economy: worldwide accessibility for food/diminishing quantitative discrepancy between rich and poor countries providing a nutritional optimum per capita decreasing waste of food Food Security: tracing/tracking of animals and products developing a good agricultural practice building responsibility for the total supply chain Sustainability: meeting technical standards like CO 2 decrease/not livi...

Twenty-two surface sediment samples were collected from Visakhapatnam harbour, east coast of India, and analysed for monophenyltin (MPT), diphenyltin (DPT), triphenyltin (TPT), total bacteria, and TPT tolerant bacteria. Concentrations of MPT, DPT and TPT varied between 1-26, 3-28, and 0.31-145 ng Sn g(-1) dry wt, respectively. Phenyltin concentrations were influenced by ship related activities,...

Applications of manures to agricultural fields have increased soil test values for P to high levels in parts of the USA and thus increased the likelihood that P will be transported to surface water and degrade its quality. Waste paper applications to soils with high STP (soil test P) may decrease the risk of P transport to surface water by decreasing DRP (dissolved reactive P) by the formation ...

Cupáková, ·. , J . Luká‰ová: Agricultural and Municipal Waste Water as a Source of Antibiotic-Resistant Enterococci. Acta Vet. Brno 2003, 72: 123-129. The occurrence of enterococci in different waste waters from two cattle farms in south and north Moravia and sewage treatment plant of the University of Veterinary and Pharmaceutical Sciences Brno, Czech Republic was investigated.
