Glyphosate-based herbicides on weeds management and maize performance under conservation agriculture practices in eastern Kenya
A three-season research study was conducted at Embu Agricultural Research Station farm to determine the effect of glyphosate-based herbicides on weeds management and maize ( Zea mays L. ) performance under zero-tillage conservation agriculture practice. Glyphosate herbicide sprays were prepared from Roundup Turbo product at the rate of 2.5 L ha –1 and Roundup Weathermax at 1.5, 2.5 and 3.0 L ...

Spatial variability of Atrazine and Metolachlor dissipation on dryland no-tillage crop fields in Colorado
An area of interest in precision farming is variable-rate application of herbicides to optimize herbicide use efficiency and minimize negative off-site and non-target effects. Site-specific weed management based on field scale management zones derived from soil characteristics known to affect soil-applied herbicide efficacy could alleviate challenges posed by post-emergence precision weed ...

Control of cereal rye with a roller/crimper as influenced by cover crop phenology
Adoption of reduced tillage practices have been driven by the need to enhance soil quality, minimize field labor time, and scale up farm size. However, concerns about increased reliance on herbicides and demand for organically grown foods call for adoption of production practices that can reduce both tillage and herbicide use. This research study assessed the influence of planting and termination ...

ASA Survey Shows Herbicide Strategy Compliance Difficult for Farmers
The Environmental Protection Agency has proposed several pesticide registration plans that could significantly affect farmers’ abilities to utilize herbicides. EPA is responsible for approving registrations on pesticides in the United States and has consistently been found by courts to have not properly evaluated the registrations’ effects on endangered species. In order to meet ...

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 ...

Giant black-grass requires lock stock approach
Nigel Riches, Arable Technical Specialist for Certis, explains what he’s been seeing in the field. “Black-grass is a problem that in the past has generally been confined to the main arable areas, in the east of the country. “But increasingly we’re seeing this pernicious weed spreading further west each season. Where previously black-grass has not been a big issue in the ...

Weed control in organic farming
Probably the most cost-intensive and time-consuming operation in organic farming is the elimination of weeds at different stages of plant development. Due to the impossibility of herbicides application, the processing must be performed mechanically. For this purpose farmers use a wide variety of rotary and striegel harrows, cultivators and tillers for interrow processing and ...

LCA of integrated orange production in the Comunidad Valenciana (Spain)
In order to perform an LCA of integrated orange production in the Comunidad Valenciana two representative areas were studied. The functional unit was 1 kg oranges at the farm gate. Eight scenarios were considered according to type of irrigation, the origin of water and the tillage practice. The production of agrochemicals, the production and use of energy in agriculture (for irrigation and ...

Behavior of atrazine in limited irrigation cropping systems in Colorado: prior use is important
Received for publication October 28, 2008. Glyphosate-resistant (GR) corn may be a major component of new cropping systems to optimize the use of limited irrigation water supply while sustaining production. Because atrazine is an important tool for residual weed control in GR corn, we examined atrazine binding to soil, dissipation, movement, and early season weed control in limited and full ...

Because atrazine is an important tool for residual weed control in GR corn, we examined atrazine binding to soil, dissipation, movement, and early season weed control in limited and full irrigation cropping systems.

Jointed goatgrass management with Imazamox-resistant cultivars in a winter Wheat–fallow rotation
Jointed goatgrass (Aegilops cylindrica Host) is an economically important weed in winter wheat (Triticum aestivum L.)–fallow production regions of the United States. Few options exist for management of jointed goatgrass in winter wheat due to the close genetic relationship between the two species. This research evaluated use of imazamox herbicide ...

Variation in characteristics and imazamox tolerance of feral rye
Rye (Secale cereale L.) is a minor crop in America, with similarities to wheat (Triticum aestivum L.) in growth habit and distribution. However, feral rye has become a weed in wheat. Little is known about variation in feral rye morphological characteristics that influence success of cultural controls. Thus, 21 feral rye populations were sampled from wheat fields in central Oklahoma to ...

Growing currants and other berries organically
Northern of Latvia is region where there are relatively many crops with ecological berry plantations – including currants. As a company, we had the opportunity to personally see it in June this year. Together with our dealer – the SIA POLTEH company we took part in the Farm’s Open Day ( which was organized by ones of the local berry’s producers. The event was accompanied ...

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, ...

Local advice on managing blackgrass
Blackgrass is a weed that troubles many, and controlling it is an increasing challenge, particularly with the small armoury of products available, and the growing issue with resistance. Paul Drinkwater, Crop Production Manager for Abbots Ripton Farming Company, explains how, in his 40 years of being in the Cambridgeshire area, the blackgrass problem has evolved. “My role sees me manage ...

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 ...

Three reasons the F15/F15B is ideal for fall fieldwork
As all farmers know, there’s no rest after harvest—as soon as the crops are in, it’s time to prep seedbeds for next planting season. Fall fieldwork is key to generating good emergence and yield, so it’s important to get it right. Here’s a few reasons why AMCO’s F15/F15B Double Offset Tandem Disc Harrow is the perfect tool for the job: The F15/F15B breaks up ...

Conservation: It’s the right thing to do
A fable of six blind men and an elephant originated centuries ago somewhere on the Indian continent. In it the blind men try to identify an elephant by touching only one part. According to the fable each man came to a different conclusion as to what the elephant was. The parable illustrates that though opinions may vary, there’s some truth to be found in all of them. That’s the way ...

How a new way of thinking about soil sparked a national movement in agriculture
For three weeks every month, Ray Archuleta captivates audiences with a few handfuls of soil. He begins with two clumps, dropping them into water. The soil from a farm where the soil isn’t tilled holds together, while the tilled soil immediately disperses, indicating poor soil structure. Next, volunteers from the audience — mostly farmers and ranchers — pour water over a soil ...
