Unfortunately you will notice only a couple of months after planting …
Often we get the question about “how you can see the coir quality is stable”. Well that is very diffcicult to see as most new coir look good. If you feel the coir some soft and spongy and the color is more light brown, it might be too young raw material. That will decompose too fast, starting soon after planting. That will not happen to our coir products.
Dutch Plantin’s product characteristics:
- physical structure remains stable during the whole crop
- stable coir is easier to buffer and wash to low EC at the start
- Sodium and Potassium at low levels for an optimal culture
Dutch Plantin has been producing stable coco for over 20 years in line with a special treatment which avoids the fast decomposing of the structure during the crop. The material is of a certain age in order to retain a good structure for several years, which is the first step of the process. The lignin content increases during this period, which makes the particles more solid. Plus the cellulose content decreases at the same time. The result is that the coco peat’s structure will not slump, but instead will remain airy.
We developed our coco especially for roses and strawberries in the nineties, to be used in crops for many years before renewal. Growers and consultants had already known for years that the physical structure remained very strong for a long time with a balanced air/water ratio.
It is also of great importance that you mix a stable coco for potting soil: only then will you have a mixture which will satisfy customers in the long run.
Dutch Plantin’s buffered coco to avoid surprises in chemical analyses after planting: Sodium and Potassium are at low levels. This is the only way to ensure Calcium is amply available to the plants. For growbags the buffering can be realised by the growers themselves most of the time and we will assist to ensure they succeed.
It is difficult to get a balance in Ca – K/Na when non-buffered coco is used and the first crops will therefore be affected by Calcium deficiencies in leaves and flowers.
Many crops, and especially tomatoes and strawberries, are (very) sensitive to this and a good stable coco “guarantees” a good yield & quality. Seedlings, cuttings and young plants will be of the best possible quality when rooted in our stable coco.
