GROWTH
in the winter, we have to use chemicals. Applying an artificial fertiliser
takes between 7 to 10 days to show signs of uplift. Iron (Fe) is often applied to improve the aesthetics quickly. By this time we are mowing it in order to control the growth, particularly when the temperatures and vigour are favourable. Unfortunately, due to labour or equipment restraints, there is insufficient time to keep on top of this and the grass gets away, so we “manage” it with a growth regulator. Not only can the GR reduce
top growth, it can also improve rooting, create denser sward and improve colour. However, it does mean that we have to put some nitrogen (N) on to offset browning off. It’s good, it’s effective. Although the greenstaff can
products affecting the balance of gibberellic acids (GA) are common place. The GAs shows very marked effects on growth, in particular promoting the rapid extension of plant cells. Today’s GRs have proven chemical hormonal effects on the GAs, i.e. they suppress them, thus reducing the stem elongation. When you apply synthetic,
non organic nitrogen the plant language changes. Growth cell elongation, stem elongation and
utilise the plant GR to manage aggressive grass behaviour following high N applications, it is vitally important that the application rates and timings are carefully managed. In most recent times,
cell division are triggered more aggressively. The grass plant sugars are increased but, due to elongation of the leaf, stem and vegetation, you now have to mow more often to control the additional growth. As a result, the plant becomes stressed and the sugars manufactured within the leaves are not able to return food to the brain, i.e. the roots. The plant then becomes more out of balance, roots are starved and root hairs are not replaced or satisfied. Root hairs only live for seven
to ten days, and that is in ideal horticultural soil, not compacted, toxic, shallow rooting rootzone with over applied NPK (nitrogen, phosphorus, potassium) with a thatch organic layer. So, the spiral continues in a
