  • Seeding rate and planting arrangement effects on growth and weed suppression of a legume-oat cover crop for organic vegetable systems

    Winter cover crops can add soil organic matter, improve nutrient cycling, and suppress weeds in organic vegetable systems. A 2-yr study was conducted on organic farms in Salinas and Hollister, CA, to evaluate the effect of seeding rate (SR) and planting arrangement on cover crop density, ground cover, and cover crop and weed dry matter (DM) with a mixed cover crop. The mix contained legumes (35% ...

  • 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 ...

  • Hairy Vetch management for no-till organic corn production

    Rolling-crimping to control hairy vetch (Vicia villosa Roth) may make organic no-till corn (Zea mays L.) possible. This study investigated how rolling-crimping date and growth stage of the cover crop affected hairy vetch control and if a rolled-crimped hairy vetch cover crop could supply weed control for no-till corn. Hairy vetch was planted in late August and was rolled and crimped and planted ...

  • Effects of the herbicide imazapyr on juvenile Oregon spotted frogs

    Conflict between native amphibians and aquatic weed management in the Pacific Northwest is rarely recognized because most native stillwater‐breeding amphibian species move upland during summer, when herbicide application to control weeds in aquatic habitats typically occurs. However, aquatic weed management may pose a risk for aquatic species present in wetlands through the summer, such as the ...

  • Summer cover crop and management system affect lettuce and cantaloupe production system

    Cover crops are widely used in both conventional and organic systems to protect and improve the soil. This study evaluated the effect of summer cover crop and management system on the production of fall romaine lettuce (Lactuca sativa L.) and spring cantaloupe (Cucumis melo L.) from 1999 to 2003. Cover crop treatments included cowpea [Vigna unguiculata (L.) Walp.] incorporated (CPI), cowpea used ...

  • 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 ...

  • How green was my Vertical Farm?

    By 2050, 80% of the earth’s population will live in cities and 3 billion more people will need to be fed. The simple fact is we are running out of available land to grow enough food to feed them. If we can’t grow our cities outward to find more arable land, the only solution is to grow them upwards. This may change the way we design cities forever.The problem is real and immediate. Even by most ...
