  • Potato Processor

    Problem: A major potato processor was faced with odor and downstream land application difficulties. Solution: After reviewing their wastewater treatment process, the source of their problems was identified as a high strength recycle stream, comprised of filtrate and spray bar water from the vacuum drum filters. This stream was being returned to the ...

  • Potato Flume Water 1

    This client transports potatoes from their receiving dock to the processing area of the plant in a water flume. This process removes the dirt from the fields. The pH was 6.3 and did not require pH adjustment. The sample was tested with I, H, and K and it was determined that the K was the best product for clarity, reduced dosage and floc size. The samples were treated with 0.13 grams of Floccin-I, ...

  • Tests of taxonomic and biogeographic predictivity: Resistance to disease and insect pests in wild relatives of cultivated potato

    A major justification for taxonomic and biogeographic research is its assumed ability to predict the presence of traits in a group for which the trait has been observed in only a representative subset of the group. Such predictors are regularly used by breeders interested in choosing potential sources of disease and pest resistant germplasm for cultivar improvement, by genebank managers to ...

  • Effects of low concentrations of herbicides on full-season, field-grown potatoes

    Current phytotoxicity plant test protocols for US pesticide registration require testing for effects on seedling emergence and early growth without regard to other important factors, such as plant reproduction. Yield and quality reduction can have significant economic and ecological effects. Therefore, field trials were conducted to determine if potato (Solanum tubersum L.) vegetative growth and ...

  • Introgession of wild species germplasm with extreme resistance to cold sweetening into the cultivated potato

    Potato (Solanum tuberosum L.) breeders are interested in developing chipping cultivars that can be stored at cold temperatures to reduce storage losses and increase profitability for potato producers. Commercial cultivars accumulate reducing sugars during cold storage, resulting in unacceptably dark chips when processed. In this study, we have identified diploid wild Solanum species accessions ...

  • Soil microbial, fungal, and nematode responses to soil fumigation and cover crops under potato production

    Abstract  Sodium N-methyldithiocarbamate (metam sodium) and 1,3 dichloropropene are widely used in potato production for the control of soil-borne pathogens, weeds, and plant parasitic nematodes that reduce crop yield and quality. Soil fumigation with metam sodium has been shown in microcosm studies to significantly reduce soil microbial populations and important soil processes such as C ...


  • Organic amendment history and crop rotation effects on soil Nitrogen mineralization potential and soil Nitrogen supply in a potato cropping system

    Crop management practices influence readily and potentially available N in soil. In this study, we evaluated the effects of organic amendment history and crop rotation on potentially mineralizable N (N0), mineralizable N pools, and field estimates of soil N supply in potato (Solanum tuberosum L.) production, and evaluated a suite of N availability measures to detect changes in these parameters. ...

  • Advancements in chemistry are providing growers with flexibility when managing slug pressures in potato crops.

    Flexibility in slug control The mild and wet weather and lack of ground frosts seen this winter, means that being vigilant to slug activity will be key as we move into the potato planting season. Andrew Sprunt, Agrii’s Northern region potato technical agronomist, explains what growers can expect from the season ahead, and how to manage the potential impact at farm level, ...

  • Bulk carbon, oxygen, and hydrogen stable isotope composition of recent resins from amber-producing Hymenaea

    Antimicrobial peptide magainin II, isolated from the skin of the African clawed toad, has shown activity in vitro against a range of micro-organisms. Transgenic potato lines expressing a synthetic magainin gene show improved resistance to the bacterial plant pathogen, Erwinia carotovora. Culturable bacterial and fungal communities associated with magainin-producing potato plants were compared ...

  • Compost, manure and synthetic fertilizer influences crop yields, soil properties, nitrate leaching and crop nutrient content

    From 1993 to 2001, a maize-vegetable-wheat rotation was compared using either 1) composts, 2) manure, or 3) synthetic fertilizer for nitrogen nutrient input. From 1993 to1998, red clover (Trifolium pratense L.) and crimson clover (Trifolium incarnatum L.) were used as an annual winter legume cover crop prior to maize production. From 1999 to 2001, hairy vetch (Vicia villosa Roth.) served as the ...

  • Modified atmosphere packaging of dried fruit and fruit snacks - Case Study

    Systech Illinois’ oxygen headspace gas analyzer helps Whitworths maintain the quality of a million packs of dried fruit every week.  In the UK, Whitworths produces around a million packs of dried fruit and fruit snacks each week using modified atmosphere packaging (MAP) to ensure long product shelf life. Sample packs are tested every hour using a Systech headspace gas analyzer ...

  • Lindsay Irrigation advances Watertronics AG Pump Stations case Study

    When AJ Ochoa, a fourth generation Othello, Wash. farmer pushed one button to start his new Watertronics® agricultural pump station, he became one of the first irrigators in the world to reap the benefits of a fully integrated pump and center pivot water control package. Even more important to Ochoa, he began realizing immediate and substantial reductions in energy, water and labor costs. ...

  • How three U.S. mini-farms are sowing the seeds of global food security

    Tiny, biointensive operations show smallholder farmers from around the world how they can grow far more food than conventional approaches. Her face shaded by a wide-brimmed straw hat, Olawumi Benedict is cheerfully tending to her “little babies” — kale seedlings growing in shallow wooden flats until they’re hardy enough for transplantation into soil beds. Three miles over ...

  • A big slug year ahead?

    In addition to the weather, stubble clean-ups and green bridge carry-over are the two other major contributors, which means that high slug pellet usage on farms across the UK is likely this year, explains Justin Smith agronomist for Bartholomews Agri Food Ltd. “I work with farmers in the East Sussex and Kent areas, most of whom farm in vulnerable water catchment areas and are looking for ...

  • One Year Later · Persistent Herbicides in Compost

    ONE YEAR has passed since the Washington State University (WSU) composting facility and the Spokane Regional Compost Facility discovered traces of persistent herbicides in their composts. In Spokane, the source of contamination is a compound called clopyralid. Compost contamination at WSU initially involved the herbicide picloram, but clopyralid has since been detected in the compost also. In ...

  • Arsenic in irrigated paddy soils

    Natural arsenic pollution of drinking water has been reported from over 70 countries world-wide, affecting an estimated 150 million people (Ravenscroft et. al., 2008). About 50 million of these people live in Bangladesh, 30 million in India and 33 million in six other countries of south and south-east Asia. It has recently been recognised that arsenic-contaminated groundwater used for irrigation ...
