Hi there.. as Ray and I have no experience with this sort of a situation I was wondering if anyone could give me some idea on how the pasture and soil will be likely to be affected after the fire last week.
Are we likely to lose topsoil? Will the grass grow back or will we have to re-sow?? I don’t even know what sort of grass we had except that it was thick and lush before it started to dry out for summer.
I understand that this is like asking how long is a piece of string but any information will be gratefully accepted. I’ve spoken to the dpi who directed me to information sheets on their website but the pdf on pasture regeneration spoke of “cool” fires, “hot” fires etc and that really just confused me more. Certain fires can scour the soil and damage it considerably apparently.
I’m at a loss to know where to begin with this one.. :geek:

Give these guys a call, they are pretty well on top of all soil issuses and great to talk too.
Feel free to post any good advice they offer.

Between these two there is not much else they don’t know about soil.November 29, 2006 at 12:16 am #282673starkMember
Lolly a cool fire is one that burns fast like a grass fire with little heat in it,a hot fire is where trees and rubbish has generally burnt in the one spot for a long time
%90 of grasses will regenerate themselves but so will weeds and if you have wattles around expect thousands of them to sprout
If you have the dollars now would be good time to disk soil and plant with a pasture while the ground is clear if not you will still end up with grass but with weedsNovember 29, 2006 at 2:56 am #282674AnonymousInactive
yep with Stark on that one,,,
Knowing what FSF looks like, I dare say you guys suffered a cool fire.. (did you lose and tree or two ?? it may have got “hot” around any dropped branches that may have burnt…
With Stark here as well.. get a disc into the sucker.. and if you can , buy some native grasses, either seeds or tubes.. and get them in the ground. I know at Wail nursery they have tubes of grasses (around 20cm height) for 50c I got $5 worth the other day, and planted them in,, trying to get them all established now while the weeds have fissled out for the summer.November 29, 2006 at 4:09 am #282675bazmanMember
You should be able to buy improved Pasture seed at your local produce/feed shop.
I mixed up a bucket with half dolomite half seed, then used a 2lt milk bottle to spead the seed around.
Find out the best grass for your area when you sow it add some legume seed like clover or lucene, this will help add nitrogen to your soil.November 29, 2006 at 5:04 am #282676AnonymousInactive
Or if you are really nice to Ziggy (the other Dan) he may be able to get you some Vetch, which is fantastic for nitrogen (as long as you slash it before it seeds/flowers)
After thinking about it, I would be taking this oppurtunity to really get in a do some hard work, like running swales into your FSF Swamp.. I’m sure once harvest is over Dan and could come give a hand…November 29, 2006 at 1:16 pm #282677ziggyMember
just remember it is a long dry summer and discing it now will almost surely bring it up too fine and it will blow. The best thing to do is to leave alone and as soon as we get a rain of say 20 points there will be a germination, if it is disced it may not get as much germination of plants as the water goes straight through the top soil. In the meantime if it does start to blow the top soil away. then look at doing something like ripping a narrow furrow in every half metre or so. At the moment a lot of my neighbours have either over grazed there padocks or dug up there failed crops, in doing this they will lose a lot to wind errosion so you can expect big dust storms in comeing months because of this. Some seeds are lost in fires for eg: ryegrass as it is very small and the heat gets in it, other larger seeds sirvive the heat well and it pops the outer coating to help it germinate. Fire is a very usefull tool sometimes, it also puts ash into the soil which can be good. As far as the carbon side if things it is a bit like the biofuel in that it releses carbon gathered over the last growing season. It is really hard to go past cell or strip grazing as a weed control system. cultivation of any sort before sowing winter crops is very bad for the soil in most cases depending on the conditions, it is the old ways (so to speak). Looking from the road today as I went past it appears to be quite a fast burn which is the usual on a windy day. This means that the top of the plant is burned off and quite a lot of the lower part is left ( this can be seen in the wheel marks after the burn has been through). If there is enough unburned plant stem and root loosing the top soil shouldn’t be a problem. Takeing all this into acount I would definately say leave it and if you wish sow something, do it after the first break in about the first week in may.
