Water and irrigation
October 2017 – Preparation for painting my home office/study recently required a serious clearing out, and I undertook a somewhat enforced go-through of my filing cabinet. You know the feeling. (If you don’t, do it sometime, it’s pretty liberating. But be warned, it will take you much longer than you think!) Three drawers packed tight with technical crop information from the late ’80s onwards. (Now you see why it was liberating.)
July 28, 2016, Tel Aviv, Israel – Netafim, the global leader in smart irrigation solutions for a sustainable future, has released its 2015 Sustainability Report, which demonstrates how its 2020 Sustainability Strategy is aligned with the Sustainable Development Goals (SDGs)recently adopted by the UN.
August 2016 – It’s that time of year again already. Except it’s not! Level 1 water restrictions came into effect in Metro Vancouver on May 15, two weeks earlier than in previous years, the result of requiring Level 3 restrictions last summer for the first time since 2003.
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.”
