Corn belt assessment of cover crop management and preferences
Surveying end-users about their use of technologies and preferences provides information for researchers and educators to develop relevant research and educational programs. A mail survey was sent to Corn Belt farmers during 2006 to quantify cover crop management and preferences. Results indicated that the dominant cereal cover crops in Indiana and Illinois are winter wheat (Triticum aestivum L.) ...

Nitrogen supply for cover crops and effects on peanut grown in succession under a no-till system
In Brazil, as no-till (NT) crop management expands, there is an increased interest in growing peanut (Arachis hypogaea L.) with this system. However, it is not known if the preceding cover crop species, the amount of straw on the soil surface, or the N supplied to the cover crop will affect peanut grown in a NT system. An experiment was conducted on a Typic Haplorthox in Botucatu, São Paulo ...

Stockwell on Soil: Logic On Side of Cover Crops & No-Till
While reading this article I noticed #6 in the list includes cover crops and no till. We often talk about the very same benefits discussed in number six, but the important lesson here is the frame. First, the opening or introductory message is NOT about cover crops or soil health. As much as we all love to delve into those topics, the majority of producers do not (I know, hard to believe, but ...

Scouting for pest in Iowa cover crops
Landscape diversification, including the use of cover crops, can provide habitat and forage for beneficial insects. This is especially true in the spring when there is a lack of food. Alternatively, cover crops can also support field crop pests, including moths, beetles, flies and slugs. The early spring vegetation, sometimes called a “green bridge,” provides resources until the row ...

Damatta Bio Farmer (Cezar Villela), Brazil - Case Study
EFFECTS OF VARYING COVER CROPS ON SOIL RESPIRATION IN A BRAZILIAN OXISOL A Cover Crop/ Soil Respiration Study in Brazil: Validating gains in soil biology with Solvita CO2 – results after 1 growing season. Brazilian Oxisols are high in clay with low natural fertility. This poses a challenge for growers. To test the potential for soil improvement various grasses and legumes were grown for an ...

Integrating winter annual forages into a no-till corn silage system
The benefits of cover crops within crop rotations are well documented, but information is limited on using cover crops for forage within midwestern United States cropping systems, especially under no-tillage management. Our objective was to evaluate plant, animal, and soil responses when integrating winter cover crop forages into no-till corn (Zea mays L.) silage production. Three cover crop ...

Cover crops and organic mulch to improve tomato yields and soil fertility
Cover crops and organic mulches (OMs) have been reported as a means to reduce inputs and increase soil quality. A field experiment was conducted to elucidate the effects of summer cover crops and organic compost on winter fresh market tomato (Lycopersicon esculentum Mill.) yields and quality. Cover crops were sunn hemp (Crotalaria juncea L.), velvetbean (Mucuna pruriens var. utilis), cowpea ...

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 ...

Brassica cover crops for Nitrogen retention in the mid-Atlantic coastal plain
Received for publication February 5, 2008. Brassica cover crops are new to the mid-Atlantic region, and limited information is available on their N uptake capabilities for effective N conservation. Forage radish (Raphanus sativus L. cv. Daikon), oilseed radish (Raphanus sativus L. cv. Adagio), and rape (Brassica napus L. cv. Dwarf Essex) were compared with rye (Secale cereale L. cv. Wheeler), a ...

Earth Innovations: Cover Cropping
Earth Innovations is a new series from Sound Agriculture that covers the up-and-coming techniques growers are deploying to keep their yields high and their land healthy for generations to come. In each blog post, we break down the benefits and challenges of incorporating new practices, using real growers’ experiences and the Sound Agronomy Team’s expertise. Cover crops are ...

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% ...

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 ...

Self-seeded cereal cover crop effects on interspecific competition with corn
Perpetuating cereal cover crops through self-seeding may increase adoption by reducing risk and cost. Winter rye (Secale cereale L.), wheat (Triticum aestivum L.), and triticale (x Triticosecale Wittmack) were used to develop self-seeding cover crop systems in a soybean [Glycine max (L.) Merr.]–corn (Zea mays L.) rotation. Cereal cover crops were planted in varying row spacing configurations and ...

Cover Crop and nitrogen effects on maize productivity in no-tillage systems of the Brazilian Cerrados
Cover crops in direct seeding mulch-based cropping (DMC) systems can be an effective tool to optimize N management for crop production in the Brazilian cerrados. The objective of this study was to determine the effect of four cover crops on maize (Zea mays L.) grain yields in two fields that had been under DMC for 3 and 14 yr. We hypothesized that cover crops would optimize N supply to the maize ...

Fall Tillage Practices And Cover Crops
In my area of Iowa, primarily in Mitchell County, the adoption of strip-till has been huge. There were three or four people that started in the early 2000s, along with my dad, that were pretty vocal about what they were seeing and what kind of benefits they were getting from reducing tillage and going to a strip-till pass. I would love everybody to switch to strip-till and then to no-till down ...

Enhancing nutrient cycling by coupling cover crops with manure injection
Coupling winter small grain cover crops (CC) with liquid manure injection may increase manure nutrient capture. The objectives of this research were to quantify manure injection effects using target swine (Sus scrofa) manure N rates of 112, 224, and 336 kg N ha–1 on CC plant density, fall and spring shoot biomass, N, P, and K uptake and subsequent corn (Zea mays L.) yield. A winter rye (Secale ...

Cover crop effects on the fate of N following soil application of swine manure
Abstract Cereal grain cover crops increase surface cover, anchor corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] residues, increase infiltration, reduce both rill and interrill erosion, scavenge excess nutrients from the soil, and are easily obtained and inexpensive compared to other cover crop options. The use of cereal grain cover crops in fields where manure application occurs ...

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 ...

Establishment and growth of self-seeded winter cereal cover crops in a soybean–corn rotation
Perpetuating cereal cover crops through self-seeding may increase adoption by reducing risk and cost. Winter rye (Secale cereale L.), wheat (Triticum aestivum L.), and triticale (x Triticosecale Wittmack) were used to develop self-seeding cover crop systems in a soybean [Glycine max (L.) Merr.]–corn (Zea mays L.) rotation. Cereals were planted and managed chemically and mechanically in varying ...
