I am inquiring re a trial of CT and Compost we are planning to do.The trial=
is with Cucumbers in a green house. The cucumbers are usually grown with c=
onventional hydroponics.
The trial will involve using CT to control Powdery Mildew as well as a soil=
drench.
Some of the cucumbers will be started in 100% compost in jiffy pots (tiny s=
tarter pots) others will be in conventional potting mix, and then placed on=
the main growing media to grow out. The media being used is pine sawdust a=
nd chips (pinus radiata). We plan to use CT as a drench on the growing bag=
s and also place a small amount of compost on top of the growing bags befor=
e placing the seedling plant on top of the growing bag.
The CT will be fungal dominated but with some bacterial component. Typical =
range as follows.
Total fungal biomass 38 ( micro g per ml)
Active fungal biomass 14 ( micro g per ml)
Total bacterial biomass 230 ( micro g per ml)
Active bacterial biomass 40 ( micro g per ml)
CT will be used weekly as folia to control PM and other leaf diseases. No s=
ticker spreader is to be used.
We are unsure as yet how the CT will be applied, a fogger is one way the gr=
ower usually applies fungicides. Anyone have experience with these machines=
? I do not have the specifications but suspect that the pressures will be t=
oo high.
The water for the hydroponics is not recycled, used once and then used on o=
ther things, the growing bags (full of pine) are recycled if possible i.e. =
after the crop is finished a new one is planted on top of the media in the =
bag.
We hope to take brix readings and will be able to compare with other houses=
on the property.
We expect to be able control PM and show improved quality.
Hopefully it will not be too long till the leaf testing kit will be availab=
le, this would be a great opportunity to use it as we are too far from a la=
b to send leaf samples.
Any suggestions re improvements we could make to this trial??
Regards Mike Harvey.
