  • De-inking paper sludge amendment affects weeds in the presence or absence of herbicide in a soybean-corn rotation

    The application of de-inking paper sludge (DPS), a C-rich but N-poor soil amendment, can sometimes decrease plant growth. This property needs to be investigated to develop the knowledge and management methods necessary for potential weed control. Today, there is no information on the effectiveness of using DPS to control weeds within a soybean [Glycine max (L.) Merr.]-corn (Zea mays L.) rotation. ...

  • Using Compost To Control Plant Diseases

    Losses due to soilborne diseases on some greenhouse, nursery and vegetable crops can amount to thousands of dollars per acre annually. Until the 1930s, organic amendments — consisting of animal and green manures, coupled with crop rotation — were principal methods of control. But these approaches were largely abandoned for reasons of cost and inconvenience after commercial fertilizers and the ...

  • An assessment of the suitability of backyard produced compost as a potting soil

    Current scientific knowledge of compost is largely derived from research into commercially produced green compost. This has shown that such compost tends to have high pH, high conductivity, and potential for organic and/or mineral pollutants and therefore can be problematic for use in growing media at high inclusion rates. Little work has been undertaken at an amateur composting scale and it is ...

  • Non-chemical Pre-plant Soil Disinfestation

    The battle with pests, diseases and weeds is an everyday problem for every farmer. Due to the fact that 40% of the world’s food production is lost due to pests and diseases, farmers need to manage crop protection. An excellent example of the need for pesticides is cotton. It is a crop that is affected by various pests. Cotton farming accounts for more than 25% of all insecticides and 12% of ...

  • Biocontained mortality compost using liquid manure

    During disease outbreaks, composting has been used to safely dispose of carcasses and infectious solid manure. However, optimized methods have not been established to use liquid manure (> 80% water content, WC) from dairies as the substrate for mortality composting. In April of 2007, a 3x2 factorial study was conducted in wooden compost bins (240 x 240 x 140 cm) lined with 0.5 mm plastic to a ...

  • 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 ...

  • Pesticides in the European Union

    There has been a sharply falling trend in the total volume of sales of agricultural pesticides in the EU between 1991 and 1995. But this was reversed in 1996. From 1991-1995, EU sales of pesticides, measured by weight of active ingredients (ai), fell by 13%. They then rose by 6% between 1995 and 1996 to stand at 299,826 tonnes ai. But this still put them nearly 8% below the 1991 figure. The use ...

  • Organic coffee production, shade coffee, quality coffee

    Organic coffee can be considered to be passive or active. Passive organic coffee production systems are systems that do not apply any form of chemical input. Active organic coffee production systems also do not apply chemical inputs but in addition they comply with a range of other criteria needed for organic certification. Organic certification is a necessary step if the coffee is to be exported ...

  • 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 ...

  • Coffee production systems

    Types of production systems Roughly, five types of coffee production systems can be distinguished (Moguel, 1996, in Courville, forthcoming): 1)Traditional rustic coffee system: coffee production under forest trees by substitution of plants growing on the floor of a (sub)-tropical forest with coffee. There is a minimal impact on the original forest ecosystem; 2)Traditional polyculture system ...
