Injecting slurry

[Bald Rick]

With the looming whole Wales NVZ on the horizon, thought is turning to managing slurry in a way that may reduce the fingering
So the question is

How often can you inject in to grassland without seriously damaging the root mass?

 

[Ted M]

We go every 5-6 weeks with trailing shoe, so bit kinder on the ground than a disc.
Anything from 2-4000 gal/acre depending on the thickness of the slurry

 

[bez]

We find that going every 5 weeks with the disc injector doesn’t cause the damage we thought it would.
Ours is a shallow disc injector, so maybe we aren’t going deep enough to do any lasting damage.
It makes a real tidy job.

 

[jimmer]

Aye up lads, there will be a top of the range second hand slurry injector for sale in 6 months

 

[Carwyn31]

We inject all silage ground after each cut 5/6weeks and dont see any issues. Have massively cut down the fertiliser bill aswell since startimg injecting

I saw a joskin injector tanker demonstrated here in '07 when we got our province wide NVZ. It didn't catch on.

Issue 1 Bouncing over stones, stones rising, and machine wear.

Issue 2. Might be ok after 1st cut when ground is hopefully dry. But I saw it demonstrated in early spring, and the tractor could hardly pull it when the injector was in work. And it was nice enough ground. Tractor peeled off big sods. Disaster demonstration. Ended up having to just touch the injector on the surface and dribble it on.

Yeah, that’s what we thought as it’s rare to get the soil at an ideal state but there was also the question of root damage
Looking at trailing shoe as a better alternative perhaps one that cuts a narrow slot in front of the outlet ?

We have a 7.5m mastek dribble bar and you can put 3000 gal/acre every 5 weeks no bother and wouldn't know where youd been. But the talk is dribblers could well be outlawed by 2025

Also think that there are potentially better N use/ less AN from trailing shoe.
Have to be conscious that Wales is highly likely to go all NVZ from January so the days of the splash plate are about to disappear

im not sure how they can if I’m honest. Every herd around here wouldn’t have enough storage just like that. Some still only have a few weeks worth.

Cant see how someone can think spreading slurry nov-feb is a effective use of slurry?

Grass still grows down here that time of year and get a reasonable response for the tack sheep

Don't keep more than 6 cows.

far more effective spread in nov/ dec when conditions are correct compared to a pissing wet Oct when it’s just going to run off.

we see plenty of response here. Aim to spread the grazing platform before Christmas and then onto the silage ground somewhere around mid jan.

Agree with you there, been in a NVZ for 10+ years, makes little sense with the cut off dates, why they can’t automatically extend the window if September/October have been especially wet rather than everyone having to faff about applying for a derogation is beyond me.

don’t get me wrong something needs to change because people are taking the pee. Maybe easier for me to say because the chances of our slurry entering a water course are about as close to zero as you can get. But still nvz doesn’t really seem to be the answer. If it is I expect there will be some big grants required to get up to standard.

We've had full use of splash plates for 12 years of NVZ. But that is changing, with those in the high stocking rate derogation being forced down that road soon, followed by all contractors in 2022 I think.

Wouldn't like to see dribble bars go. I think they're a great job. More width than trailing shoes, and basically do the same job. No one could walk into a field and tell the difference.

I've just finished third season I think with our 10m tanker model, and have an older plate-only ferry tanker, which wouldn't be too easy to convert.

 

[Dead Rabbits]

What is the definition of injection ? Truly knifing it in can be very destructive at certain times of the year.

A compromise that seemed to work ok here is two wavy Coulters about 2 inches apart with a drop hose between the Coulters. Only run up to 8000 gallon/acre with it but it all went in the ground pretty well.

I’m not so sure, it’s looking like the polluter pays principal may apply, NAW not flush with cash.

Slurry tankers on the road from G five days a week. How they plan to enforce it in West Wales is beyond me.
