  • The Latest in Whitefly Control

    Next month’s Greenhouse Canada Grower Day is welcoming leading researchers and crop specialists to help you tackle one of the industry’s biggest challenges. Whitefly is proving to be one of the most difficult pests to control, mainly due to the lack of effective registered chemicals that can eradicate silverleaf whitefly. It is also due to the unwillingness of biological suppliers to ...

  • Have humans tilted the climate books out of balance?

    In the great book-keeping of climate change, scientists have just discovered a big mistake. They have been wrong, they now think, to count on the mountains, the plains, the forests and the grasslands as an agency that slows climate change by absorbing carbon dioxide. It does absorb carbon dioxide. But the chilling news is that  ...

  • Passive evaporation of source-separated urine from dry toilets: UES optimization and dry product accumulation over time

    A urine evaporation system (UES) was optimized and evaluated in a laboratory by adding 5 L of urine at the same time each day for 65 days. The UES consisted of a wooden box that is open at the front only with tracks for 22 vertically stacked cafeteria-type trays and a fan and chimney at the back. Urine flowed from tray to tray via gravity exiting each tray via a weir along the long side of the ...

  • New study finds recycled phosphorus could fertilize 100 percent of U.S. corn

    The world has a problem. A phosphorus problem. Needed to fertilize crops, the bulk of phosphorus comes from nonrenewable phosphate rock. While China mines the most — producing almost half the world’s phosphorus — Morocco alone controls three-fourths of global phosphate rock reserves. Year by year those global reserves ...

  • Effects of androstenedione exposure on fathead minnow (Pimephales promelas) reproduction and embryonic development

    High concentrations (300 ng/L) of androstenedione (A4) were identified in snowmelt runoff from fields fertilized with manure from livestock feeding operations in Wisconsin. In fishes, A4 is an active androgen and substrate for biosynthesis of functional androgens (e.g., testosterone and 11‐ketotestosterone) and estrogens (e.g., estradiol‐1713). Thus, A4 has the potential to be a powerful ...

  • Ammonia sanitization of blackwater for safe use as fertilizer

    Source-separated blackwater from low-flush toilets contains plant-available nutrients and can be used as a fertilizer. The aim of the study was to evaluate the impact on pathogen inactivation when treating blackwater with urea and/or lime. Blackwater was spiked with Salmonella typhimurium, Escherichia coli O157, Enterococcus faecalis, and Ascaris ...

  • In-situ comparison of phosphorus losses between organic and inorganic fertilizers

    Phosphorus (P) is one of the limiting factors of eutrophication. P added to soil from fertilizer application could pose a threat to water quality. According to agricultural habits, swine manure (SM), oil cake (OC), biogas slurry (BS), commercial organic fertilizer (OF) and compound fertilizer (CF) were selected to compare their P losses on a slope-land under natural rainfall. The results showed ...

  • Can chemical treatments to displace radioisotopes influence soil fertility? A laboratory trial

    Soils contaminated with radionuclide pose a long–term radiation hazard to human health through exposure via the food chain and other pathways. Remediation of contaminated soils has become increasingly important. The feasibility to move radionuclides from superficial soil layers to a deeper level using an acid leaching solution was already illustrated previously. As this chemical treatment may ...

  • Persistence of endocrine disruption in zebrafish (Danio rerio) after discontinued exposure to the androgen 17β‐trenbolone

    The aim of the present study was to investigate the effects of the androgenic endocrine disruptor 17β‐trenbolone on the sexual development of zebrafish (Danio rerio) with special emphasis on the question whether adverse outcomes of developmental exposure are reversible or persistent. An exposure scenario including a recovery phase was chosen to assess the potential reversibility of androgenic ...

  • Effects on macronutrient contents in soil-plant irrigated with different quality waters and wastewaters

    The goals of this research were focused on investigating the effects of irrigation with untreated wastewater, ozone-enhanced primary treated wastewaters (O3EPTW), tap water and tap water + fertilizer on the macronutrient content in soil and plant tissues. The effect on plant development was evaluated by growing Lactuca sativa in soils irrigated with these different quality ...

  • Many Countries Reaching Diminishing Returns in Fertilizer Use

    When German chemist Justus von Liebig demonstrated in 1847 that the major nutrients that plants removed from the soil could be applied in mineral form, he set the stage for the development of the fertilizer industry and a huge jump in world food production a century later. Growth in food production during the nineteenth century came primarily from expanding cultivated area. It was not until the ...

  • Molasses Tanks For Effective Storage Of Molasses and Liquid Fertilizer

    As the UK’s sugar beet harvest is still underway, molasses production is also at its yearly high. 50% sugar by weight, beet molasses contain calcium, potassium, oxalate and chloride, making for an ideal base for a number of animal feeds over the winter. Correct storage of molasses is vital and the Enduramaxx range of Molasses Tanks are manufactured from UV stabilized polyethylene and come ...

    Organic fertilizer is processed by fermenting the animal and plant residues, it not only contains major elements that plant required such as nitrogen, phosphorus and potassium, also contains microelements such as molybdenum, zinc, iron, copper and other trace elements which is ...


  • 3 Unexpected ways to improve food security in Sub-Saharan Africa

    The United Nations’ new population growth projections show that the world is set to reach nearly 9.6 billion by 2050. This growth holds serious implications for global food security. Absent other effective measures to control dietary shifts and ...

  • Local fertilizer manufacturing: A new look at agro-business

    The American farmer works in a tough business. Aside from the demanding physical and mechanical processes to raise fertile crops from tiny seeds, the farmer must also battle against supply for adequate water, the right seeds, pest and weed control products, and various fertilizers. All these elements have added stress and cost to bring a crop to market, making it less profitable than ever to ...

  • World Population Hitting 7 Billion

    The number of people in the world is expected to reach 7 billion by the end of October 2011. Our rate of increase continues to slow from the high point of over 2 percent in 1968. Still, this year’s 1.1 percent increase means some 78 million people will be added to the global population in 2011. The human population did not reach 1 billion until the early nineteenth century, and it took ...

  • Fertilizer NPK from human urine and olive oil mill wastewaters

    The objective of this work was to determine how some wastewater acids could be used to prevent the decomposition of urea into ammonia during storage. The effect of storing human urine with olive oil mill wastewaters (OOMW) or water bubbled with CO2 (BW), was studied. Moreover, the application of two levels of urine dissolved in water OOMW, has been studied in relation to the properties of two ...

  • Treat your customers as equals! Fostering customer collaboration through social media

    The purpose of this paper is to explore, firstly, how companies and customers interact using social media, and secondly, how social-media-mediated interactions support customer collaboration. We identify two modes of interaction: the relationship-oriented mode and the instrumental mode. The former reflects relationship marketing in that it emphasises reciprocal and bilateral communication, while ...
