How Nitrogen Influences The pH Of Your Growing Medium
In standard greenhouse fertilizers, nitrogen is supplied as ammonium, nitrate, or urea. Each of these three nitrogen sources, when taken up by plant roots, produces different chemical reactions with differing effects on the growing medium pH.

Hydrogel Technology Means Growers And Their Customers Can Water Plants Less
Water and nutrient management are critical elements for quality plant production in the greenhouse. Maintaining the right amounts of available moisture and fertilizer at all times can be pretty labor intensive, but there are tools available to help you keep these inputs at optimum levels as efficiently as possible. Recently, we visited Evonik Industries’ North Carolina production plant for to see how one of these products — Stockosorb — is made, how it works, and learn the benefits of incorporating these tools in your own operation. Learn more about Evonik Industries’ Stockosorb hydrogel product on the Stockosorb website.

Canadian Sphagnum Peat Moss Association Announces Early Results of 2015 Harvest Season
According to an August 31 survey of members of the Canadian Sphagnum Peat Moss Association (CSPMA), whose members represent approximately 95 percent of all North American peat production, the peat harvest season has been adequate, but not strong, and could cause shortages and potentially higher transportation costs. Down To The Dirty Details The survey inquired about the status of CSPMA members’ 2015 Actual Harvest (including an estimate of what can be expected to be harvested for the remainder of the season) as a percentage of their 2015 Expected Harvest. The lack of a strong harvest overall may challenge peat availability. The Prairie Provinces (Manitoba 98 percent, Saskatchewan 88 percent and Alberta 94 percent), experienced early favorable weather conditions and a strong start to the year. This helped to minimize periodic, negative, weather-related conditions during the balance of the harvest season, and the harvest numbers are close to achieving the expected amounts. […]

How Bob’s Market And Greenhouses Improved Growing And Sales With Automated Soil Mixing
My father started our company 45 years ago growing bedding plants, mainly early season production and finished plants for our West Virginia market. It was in the early 1980s that we started growing earlier spring production and shipping materials to southern markets, and by the late 1980s, we also produced pansies for fall. We started using hydrogels when they first came on the market in the early 1990s and found that they really helped with our production by keeping plants healthier for these new markets. Over the years, we’ve grown to be a large young plant producer and have a sizable business growing finished plants in cell packs, 4 1/2-inch pots, 6-inch pots, gallon containers, hanging baskets, multiple sizes of large containers and large baskets for municipal use. Creating The Ideal Soil Mix With our old system, it took several workers to mix pre-made soil with slow-release fertilizers in cement […]
