Greenkeeping Tasks for September and October have become to some degree a bit repetitive. This would be fine if the desired results followed, but in the majority of cases this can't be said to be true. This month John explains the science behind the perfect autumn renovation plan to get your green started down the road to consistent high performance.
A regular reader asked this week about Calcium and its role in turf management.
To answer here is an excerpt from my eBook, Performance Bowling Greens
Calcium is needed by plants to grow and maintain health. It is a key constituent of cell walls.
Once fixed in the plant, calcium ceases to be mobile and this means if the calcium supply runs out the plant can’t move it around to where it is needed, it must take more in. This means in times of low transpiration, the grass plant can quickly run out of calcium.
If calcium availability is low or compromised grass plants can experience a range of difficulties
- Every plant needs calcium to grow.
- Once fixed, calcium is not mobile in the plant. It is an important constituent of cell walls and can only be supplied in the xylem sap. Thus, if the plant runs out of a supply of calcium, it cannot remobilise calcium from older tissues.
- If transpiration is reduced for any reason, the calcium supply to growing tissues will rapidly become inadequate.
Calcium plays a very important role in Read more
