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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Cover crop and liquid manure effects on soil quality indicators in a corn silage system
Due to a lack of surface residue and organic matter inputs, continuous corn (Zea mays L.) silage production is one of the most demanding cropping systems imposed on our soil resources. In this study, our objective was to determine if using cover/companion crops and/or applying low-solids liquid dairy manure could improve physical, chemical, and biological soil properties and overall soil quality. ...

Resilient Farming in Avocado and Citrus Orchards
This article was initially published on Freshfruitportal.com. Environmentally sustainable agriculture is not only a way to meet new customer demands or to respond to increasing pressure from regulators. Many growers implement more environmentally sustainable practices first and foremost because they believe it is the most effective way to grow food in an economically viable way, whether or not ...

Living mulch forage yield and botanical composition in a corn-soybean-forage rotation
Managing forages as living mulches during row crop production requires suppressing the forages to produce economical crop yields. The objective of this research was to identify forage plants with varied growth habit, persistence, and yield potential to provide desirable ecosystem functions in a multifunctional cropping system. Alfalfa (Medicago sativa L.), kura clover (Trifolium ambiguum Bieb.), ...

Effectiveness and efficacy of conservation options after potato harvest
Soil erosion and phosphorus (P) runoff can be severe in potato production systems in the Northeast USA, which are characterized by intensive tillage, minimal ground cover, low crop residue return, and steep slopes. We used rainfall simulators in the greenhouse and field to assess sediment and P movement associated with two conservation practices: straw mulching and application of polyacrylamide ...
