Never Underestimate the Growing Mix Selection

We’ve all learned how important global supply chains and material availability can be over the past three years. Change and uncertainty are two words that come to mind. When we talk about taking control of your inputs, specifically your growing media, versatility and flexibility are more critical now than ever before.

In this podcast, we will explore:

  • Potential solutions to increase crop quality while also increasing efficiency;
  • Ways to ease supply chain burdens using creative mix selection and incorporating different components the correct way;
  • How Berger’s approach help growers growing Beyond greenhouse production.

Control Your Inputs: Reduce Risk Through Growing Mix Selection

by: Stacey Rocklin, grower advisor

With change and uncertainty the theme of the year, how can we prepare for the unexpected? Knowing your inputs and their supply chain can help you make decisions quickly when faced with unforeseen challenges. When choosing a growing media, consider looking for a versatile mix that performs well under various conditions, thus improving your adaptability.

 

Biological Inputs and Fertilizer Decisions

Knowing more about growing media components and other additions to growing mixes can help you make informed decisions, especially during periods of short supply. Consider these two common mix additives: biological inputs and controlled release fertilizers (CRF), which both affect growing media shelf-life. The options include adding these additives directly to the crop during planting or adding them to the growing media. Two key reasons growers prefer to have these blended into their mix are labor shortages to apply them and consistency concerns. However, horticultural research has shown that each component performs better when added directly to the crop. Moreover, direct application allows growers to target specific crops or life stages, maximizing the benefits by using it only where it matters.

 

Biological inputs, specifically mycorrhizae, work best when introduced directly to plant roots and are most beneficial to plants with lengthy crop times. They may also interact with the naturally occurring, non-pathogenic microflora of peat moss during storage and transit before first use. However, our industry needs more research on how this impacts their efficacy.

 

CRFs added as a topdressing at or just after planting fertilize for the entire duration of their expected cycle. Whereas incorporation into the moist environment of a peat mix during storage and shipping risks early nutrient release into the mix, causing a higher starting EC. Even if the incorporated CRF does not release early, roots in individual pots receive nutrients more uniformly when adding CRF as a top dressing. Adding these additives at or shortly after potting results in better growth and cost savings if equipment and labor are available to do the added work (Donald J. Merhaut, 2013).

 

Higher demand for ready-to-use growing media

Another control point is in understanding the peat supply. Growers who have traditionally been mixing their growing media find it harder to source straight peat. Multiple factors are at play in producing peat moss. Starting with the end, post-harvest peat bog restoration is critical to an overall harvest plan. Restoration funds must exist before any new site gains approval to open for harvest. Considering there is no existing infrastructure like roads near bogs in remote locations before they come into use, this is a significant added expense to sourcing peat. Add how weather impacts harvest directly and how costs are rising is understandable. To mitigate weather issues, Berger has a department dedicated to managing multiple bogs across Canada to ensure a more uniform product blended across these diverse areas and secure a quality peat supply for decades to come.
