Where to get soil sample probe

Jolly good, needs a real good clean out if it’s been stood with roundup in it.
Is it a knapsack and if so does it have the internal regulator?

 

One of these. CP15

 

That’s great, inside the filler have you switched it to low which will set it to 1 bar?

I’ve a feeling though it might not have the internal regulator. When you open the filler there is a blue switch which you lift and turn.

Edit Blast I’ve just checked and it’s the piston version so it’s up to 3 bar. Did you purchase the regulator by any chance?

No,I can't see one.

 

Ok, the link shows the regulator, mine has a regulator built in but only for Max bar. The regulator in the link will prevent it working under 1 bar and will not allow more than 1 bar. This is important for applications so you get an even distribution and cuts down on the amount used which is a must for roundup with the correct nozzle for the job.
At the moment it’s spraying anywhere up to 3 bar.
So here’s one of the nozzle I use for example for my lawn feeds.

At 1 bar it produces 1.2ltrs a min. To check you either fill tank and spray in a container for 1 min or use a measuring jar. As you increase the bar strength the Ltrs per min increase. The regulator just means you know the output which is handy when checking the calculations required for whatever you are using.


Just a quick question but by your nozzle connector do you have a yellow adaptor fitted?

If you do you have a regulator already

 

Makes sense.

The one you linked to is unavailable for purchase on their site. A new search came back with this one.

Well worth getting one if yours does not have one. Will save money and give better results.

A green Anvil 1.2 will be fine to start with. It has a 1 meter width and you may have one that was supplied with the sprayer. You need the nozzle 50cm from the ground, you can measure out a short piece of say string with a weight at the bottom like a nut. This helps you gauge the height to start with. Nozzle widths are measured at 50cm.

I would start with some seaweed as you have just fed the lawn, it’s a good way of learning the ropes and it will help the lawn. I don’t think you need a dye as it’s a small area to spray but it’s a personal preference.

 

Mine has the blue 1.8 nozzle.

1.8 litres per minute @ 1 bar.

I'm guessing that will do the job.

 

thats a 1.5mtr width which is fine. What normally happens is you use a calculation to work out how much water and chemical is required for a set area. It’s done several ways but your walking speed comes into the calculation as well as the output of the nozzle.
The idea is to apply the correct amount for the area and not have any mixture left and to make sure you are with the spec on the label of the fertiliser etc that you are using.
I’ve included a pdf to help with the calibration from a company called Agrigem who also do some rather nice liquid feeds and treatments.

Sometimes though with some products you can apply more than the recommended like seaweed for example or some iron based turf tonics. You get to know some products over time but it might not be technically correct.

Normally you end up with a fair few nozzles as time goes on that suit your applications.

 

I should have added this.

Notice the output at different bars on your blue.

So on your blue using these nozzles your output may be between 1.8 or lower and over 3 ltrs per min and you change the output quality from course to medium so you have more drift. With the regulator fitted its at 1.8, a nice steady pattern and less drift. Handy when using herbicides as you don’t want drift.

 

I said my nozzle was blue, but that was from memory, now I'm thinking it could be green. I'll look in the morning.

Thanks for all the info. It's a lot to take in but I think I'm getting my head round the basics.

 

No problems, just shout if you need help.

Just make sure the whole lot is super clean as you have used roundup even if it means purchasing a cleaner powder as some products contain oil that coats and can be hard to remove if left sitting.

Whenever you use the sprayer always use just what’s required then do a triple clean, that’s use the product till it’s gone then put at least 1ltr in and shake, pump over a shingle or safe area and spray till empty and repeat 2 more times.
I keep my knapsack for just lawn work and another sprayer for the likes of roundup.

 

Any suggestions as to where to buy the liquid seaweed or is the stuff they sell at garden centres as good as anything online?

 

I think they're the dead stalks and leaves of the course grass that was all over my lawn 3 months ago. I have a Bosch Verticutter, should I run over the lawn with the machine on its highest setting to try and remove it and also to stand up any remaining stems that are still hiding under the turf grass so the mower can get to them?

 

Sorry for the late reply, Fridays is always a long day for me.

There are dozens of seaweed products, I’m using this at the moment and it’s fine. The postage ups it but as I’ve ordered a few bits and bobs it works fine for me. My only comment is the application rate that I use is over the recommended amount rate but not a problem.
