No-tillage improves broomrape control with Glyphosate in Faba-Bean
Broomrape (Orobanche crenata Forsk.) causes considerable losses in faba-bean (Vicia faba L.) production in the Mediterranean region. The application of an ultra-low glyphosate rate at an early broomrape parasitic phase, i.e., tubercle development, is the most common control system. This study sought to determine the effect of tillage system and glyphosate application on broomrape infestation, ...

Assessing the economic benefits and costs of conservation tillage
The economic benefits of the adoption of conservation tillage depend on site-specific factors, including soil characteristics, local climatic conditions, cropping patterns, and other attributes of the overall farming operation. While it is possible to draw some general inferences about components of economic returns and costs, a comprehensive assessment of the net private benefits from greater ...

Effect of loblolly pine root pruning on alley cropped herbage production and tree growth
Tillage to disrupt (prune) tree roots is an intensive practice which could improve herbage productivity at the crop–tree interface by reducing competition for water. We compared tillage effects on 9- to 11-yr-old loblolly pine (Pinus taeda L.) growth and herbage yields of annual ryegrass (Lolium multiflorum Lam.) and pearl millet [Pennisetum glaucum (L.) R. Br.] on a fragipan soil in Arkansas. ...

Effect of tillage and nitrogen rate on corn yield and nitrogen and phosphorus uptake in a corn-soybean rotation
Understanding tillage, N, and P interactions can contribute to improved N and P utilization and crop response. This study examined the interaction effects of tillage and N rate of two N sources on N and P uptake by corn (Zea mays L.). The study was conducted on Kenyon loam (fine loamy, mixed, mesic Typic Hapludolls) soil at the Iowa State University Northeast Research and Demonstration Farm near ...

Impact of varying planting Dates and tillage systems on cotton growth and lint yield production
As economic conditions deteriorated, cotton (Gossypium hirsutum L.) producers have looked to improve profit margins by reducing inputs while maintaining yields. Pairing the yield benefits from early planting with the input reductions from conservation tillage might help accomplish those goals. The objective was to determine how growth, lint yield, and fiber quality were impacted by planting ...

Potato yield and quality response to subsoil tillage and compaction
Compacted soils have been found in intensively cultivated vegetable crop regions of Central Wisconsin, resulting in the wide scale use of subsoil tillage by growers. The goal of this project was to assess potato (Solanum tuberosum L.) yield and quality response to soil compaction and subsoil tillage. Potato quality factors evaluated were marketable yield, tuber size distribution, internal ...

Economic performance of alternative tillage systems in the northern corn belt
While no-till (NT) cropping systems can provide conservation benefits in the northern Corn Belt, adoption has been low due to concerns about potential yield reductions and economic risk. Strip-tillage (ST) systems have been proposed as an alternative that may provide many of the conservation benefits of NT while maintaining productivity and economic returns. The objectives of this study were to ...

Crop response to rotation and tillage in peanut-based cropping systems
Production of peanut (Arachis hypogaea L.) in reduced tillage systems has increased in the United States during the past decade. However, interactions of tillage system and crop rotation have not been thoroughly investigated for large-seeded, Virginia market type peanut. Research was conducted at two locations in North Carolina during 1999 to 2006 to compare yield of corn (Zea mays L.), cotton ...

Soil microbial community change and recovery after one-time tillage of continuous no-till
Continuous no-till (NT) results in soil improvements, primarily in the surface 5 cm of soil. One-time tillage may improve NT systems by inverting surface soil with less improved deeper soil. Research was conducted to determine the change in abundance of soil microbial groups after a one-time tillage of NT and their recovery dynamics. Experiments were conducted under rainfed corn (Zea mays L.) or ...

Runoff Phosphorus loss immediately after poultry manure application as influenced by the application rate and tillage
Excessive or N-based application of poultry manure for crops may result in significant risk of P loss with surface runoff. This study assessed P loss immediately after poultry manure application to soybean [Glycine max (L.) Merr.] residue with and without tillage at eight Iowa fields. Manure from chickens (Gallus gallus domesticus) or turkeys (Melleagris gollopavo) was applied at intended rates ...

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 ...

Tillage effects on soil carbon balance in a semiarid agroecosystem
Tillage systems may affect soil C sequestration, with a potential impact on crop productivity or organic matter mineralization. We evaluated crop yield, C inputs to the soil, and in situ CO2–C fluxes under no-till and conventional tillage (disk tillage) during the 3- to 6-yr period from the installation of an experiment in an Entic Haplustoll of the Semiarid Pampean Region of Argentina to ...

Assessing the relationship between alternative production practices and energy and other input use in US agriculture
An important issue with regard to the overall effectiveness of conservation tillage practices in reducing the impact of agricultural production on the environment concerns what happens to energy, pesticide and fertiliser use as these practices are more extensively adopted. To gain some insight into this, the conservation tillage adoption decision is modelled. Starting with the assumption that the ...

Tillage and fertilizer effects on yield, profitability, and risk in a corn-wheat-potato-wheat rotation
Reduced tillage results in lower production costs and thus may have economic advantages for farmers. However, yield penalties, specific yield risks, or higher nutrient requirements may counteract the positive effects of reduced tillage. This study investigates long-term tillage effects (moldboard plow, and deep and shallow chisel plow) and their interactions with N fertilizer input on yields and ...
