Water and irrigation
February 2016 — Determining irrigation run times that minimize water use while sustaining optimal production is a difficult task for container nursery managers. The confined volume imposed by the container provides little buffer against under-watering and over-watering.  
Jan. 12, 2016, Whitby, Ont. — Want to learn more about aquaponics?
January 2016 — Well, well, well.
January 2016 — Growers in Canada know very well that natural winter light conditions are different than those in the fall, spring and summer. Sunlight is reported in many different ways. One can find total sunlight hours, light intensity during the seasons and light spectrum information. For example, I was looking at Edmonton, which is 53 degrees North latitude, and found the average of several years in terms of per cent sun, hours of sunshine and number of days. On an annual basis, the city has 2,345 hours of total sunlight and 325 days of sun.
Nov. 5, 2015, Gainesville, FL — A web-based irrigation system developed by researchers at the University of Florida Institute of Food and Agricultural Sciences saved 21 per cent in water use without reducing growth of container-grown landscape plants, a new study shows.
November 2015 — How effective is it? Many major municipalities throughout the world are using ozone water sterilization in their water treatment plants because ozone is a powerful disinfectant and leaves no chemical residue in the water.
October 2015 – I have written extensively on pH and electrical conductivity (EC) issues and management in bedding plants in Greenhouse Canada (March 2014 and earlier editions). Basically there are plants such as geraniums and impatiens, among others, that change the pH of the growing media towards the acidic side. However, plants such as petunias and calibrachoa, among many others, change the pH towards the alkaline side.
October 2015 – After the last “Inside View” editorial on fertilizer efficiency, a colleague in the supply industry wrote to me saying that “it is easy to put a smorgasbord [of nutrients] in front of the plants every day and let them choose what they want, instead of selectively giving them a balanced diet that doesn’t allow for overconsumption of certain fertilizers that outcompete others.”
October 2015 – Today many growers produce high value hydroponic crops in greenhouses and they have developed a growing science for vegetables and flower crops under protected cover.
Back when I first started writing about water quality and water treatment options, I made a presentation on greenhousing to participants of “WE ARE THE LAND: Energy and Food Sustainability Conference.”
July 7, 2015, Manitowoc, WI — The Dramm Corporation is in the national spotlight for making an eye-catching product.
May 8, 2015 – If the pH of your media is out-of-whack, consider checking your irrigation water alkalinity.
March 4, 2015, Guelph, Ont. – There was a steady stream of new ideas discussed yesterday at a major farm water management conference.
Ontario is making it easier for greenhouse growers to comply with regulations regarding the disposal of greenhouse nutrient feedwater by streamlining environmental compliance that will benefit farmers and enhance protection of the environment.
Feb. 26, 2015 — Nothing lasts forever, and fertilizer injectors are no exception.
