  • 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% ...

  • Knowledge of Farm Practices – The Key for Successful Farming

    Agriculture plays an important part in the world economy. One-third of the economically active population obtains its livelihood from agriculture. In Asia and Africa, millions of small-scale farmers, fishermen, and indigenous people produce most of the food consumed worldwide, in most cases on very small plots of land. Agriculture is increasingly called upon to address a wide range of critical ...

  • One crop, two ways, multiple benefits

    Nitrogen fixation is one of the best examples of cooperation in nature. Soil microbes – naturally occurring bacteria in the soil – work with plants to pull nitrogen from the air. They turn the nitrogen into a form the plant is able to use. In return, the plant lets the microbes eat some of the sugars it makes. Faba beans (also called fava beans) are one example of plants that work ...

  • 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 ...

  • Crop gene banks are preserving the future of agriculture. But who’s preserving them?

    As climate change makes crop diversity even more important, gene banks struggle to stay afloat. During the past few years of civil war in Syria, rebel fighters have destroyed Shia mosques and Christian graves, and burned and looted Christian churches while the Islamic State group has demolished priceless artifacts in the region. Nothing seemed sacred to the disparate ...

  • Crop protection 2.0: reducing environmental impact in the EU Is it feasible?

    By 2023 all EU member states must be complying with more stringent guidelines related to Integrated Pest Management (IPM). “The essence of the new guideline is reducing the environmental impact of pesticides,” says Piet Boonekamp, manager of the Bio-interactions and Plant Health business unit at Wageningen UR. “In principle this European goal can be achieved, as has been shown ...

  • Rotary batch blender mixes biological products that boost farm crops

    Agriculture has never been more challenging and fertility efficiency tools, such as inoculants, more important. Modern farmers rely on technology and production practices to significantly increase the yield of their food crops. Biological products like inoculants are a vital part of that strategy. Novozymes Biologicals is an industry leader in developing and manufacturing inoculants, which are a ...

  • 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 ...

  • EPA Sued Over Guidance Classifying Seeds Coated with Neonicotinoid Insecticides as Treated Articles Exempt from Registration under FIFRA

    On January 6, 2016, a complaint was filed against the U.S. Environmental Protection Agency (EPA) in the United States District Court for the Northern District of California by a coalition of U.S. beekeepers, farmers, and affiliated non-government organizations (Petitioners). The Petitioners allege that EPA has allowed “the ongoing sale and use of unregistered pesticide products” ...

  • The Best Practices for Using Plant Residues

    Plant residue are crop materials such as stems, leaves, and roots, that are left on the field after the harvest. In the past, farmers considered crop residue to be trash, that was usually destroyed by fire. However, today this practice is not recommended and highly is not used by farmers. There are two different ways to manage crop residues. The first method is tillage prior planting when plant ...

  • Nitrogen contribution from red clover for corn following wheat in western Ohio

    Inclusion of a winter legume cover crop into a crop rotation has been suggested as a method to provide a substantial portion of the N requirement of the following crop. While the benefits of winter cover crops such as reduced soil erosion, increased soil organic matter, and increased mulch cover have been well documented, the N contribution to the subsequent crop has shown to be variable. The ...

  • Grain legumes in northern great plains

    Cropping systems in the Northern Great Plains have shifted from fallow-based to legume-based systems. The introduction of grain legumes has impacted soil organisms, including both symbiotic and nonsymbiotic N-fixing bacteria, pathogens, mycorrhizae and fauna, and the processes they perform. These changes occur through effects of legume seed exudates, rhizosphere exudates, and decomposing crop ...
