Does Light Quantity Trump Light Quality?

Posted By MNLA eNews, Wednesday, December 27, 2017

When we think about lighting of plants, the different dimensions we consider are light quantity (intensity), light quality (spectrum), photoperiod (hours of light per day) and uniformity. Usually, we think of these four parameters independently, but we know that they interact with each other to regulate plant growth and development. Therefore, when considering photoperiodic or supplemental greenhouse lighting, we should consider these factors simultaneously. Here’s a brief summary of these two lighting applications.

How Mycorrhizae Provide Value at Your Greenhouse or Nursery

Posted By MNLA eNews, Wednesday, December 27, 2017

Plants have evolved over the years to develop several mechanisms that help them interact with microorganisms to acquire nutrients from the soil. One of the most widespread symbiotic relationships occurs between arbuscular mycorrhizal fungi (AMF) and most major agricultural crops and herbaceous and shrub species in natural ecosystems. This mutually beneficial relationship, known as arbuscular mycorrhizal symbiosis, facilitates nutrient uptake and exchange between the plant and the fungi. The plant sends carbon (e.g., sugar, lipids) to the fungus, and in return, the fungus provides the plant with inorganic nutrients and water.

Evaluating Robotic Transplanters for Plant Cuttings

Posted By MNLA eNews, Wednesday, December 27, 2017

Every grower’s situation is different with respect to the labor cost tradeoff for evaluating automatic transplanters. Robotics manufacturers can provide costing spreadsheets to evaluate return on investment. Work out your own cost to transplant cuttings manually as a point of comparison — in our grower survey it averaged $0.018 per cutting.

Monitor Your Greenhouse Environment with Five Easy-to-Use Tools

Posted By MNLA eNews, Friday, November 17, 2017

Growers attending the “Measuring and Monitoring Greenhouse Environments With Data” presentation at Cultivate’17 can be forgiven if they felt like they were in a round of speed dating. Upon entering the meeting room, the audience quickly split into five different groups, and each group went around the room, where a team of horticulture researchers each gave short presentations covering different tools that are available to growers to help them effectively manage their greenhouse environment.  Here’s a quick look at some of the takeaways from each presentation.

2017 Nursery Management State of the Industry Report

Posted By MNLA eNews, Friday, November 17, 2017

Each November, the editors of Nursery Management magazine bring you our State of the Industry research.  We surveyed a cross section of the nursery industry about the issues that are critical to their businesses. Sales, profits, shortages, surplus, expansion, and labor – it’s all here. Once we had the results, we asked noted economics expert, hort professor and Ellison Chair in International Floriculture Dr. Charlie Hall for his take. Watch for "Charlie's perspective" throughout each section, as well as input from growers like you who took the survey.

What does Trump Action to "Unwind" DACA Mean for Horticulture?

Posted By Craig Regelbrugge, AmericanHort, Friday, October 27, 2017

On September 25, the Trump administration announced that it will rescind the Obama-era Deferred Action for Childhood Arrivals (DACA) program, phasing it out over the next six months. Administration officials emphasized that this approach allows Congress an opportunity to resolve the fate of DACA recipients. The DACA program allowed qualifying undocumented individuals brought to the U.S. as children to obtain relief from deportation and the opportunity to acquire temporary authorization to work in the U.S. 

Nearly 800,000 individuals have received protection from deportation under the program. An estimated 89% of those individuals are in the workforce. While only a small percentage are believed to be employed in agriculture and horticulture, through many conversations with employers we know that some DACA recipients are key employees. Absent of a longer term resolution, these individuals will no longer be legally employable when their employment authorization documents expire. 

There is widespread sympathy for the plight of the “dreamers” as they have become known. So no surprise, the announcement was swiftly met with a firestorm of criticism, including from the business and higher education communities and some Republican Members of Congress. Economists were also quick to rebut Attorney General Jeff Sessions’ specious claim that DACA recipients have deprived hundreds of thousands of Americans from jobs. Others defended that the administration’s “unwind” approach was preferable to leaving the program vulnerable to a court challenge threated by the attorneys general of about 10 states, led by Texas.

Key technical details of how the program will be phased out can be found in a Department of Homeland Security memorandum. The big looming question is this: will the announced action finally serve as a catalyst that prompts Congress to address DACA and perhaps other long-deferred elements of immigration reform?

Posted By MNLA eNews, Friday, October 27, 2017

Weeds probably aren’t at the forefront for most American consumers buying food. But if farmers could no longer control weeds with existing herbicides, Americans would take notice pretty quickly.
