Bizarre - me too.
Or look up Victoria Palmer...
We grew a field of lucerne here after the oil crisis in the early '70s it did really well. Initially we made hay with it but as we moved more towards silage - and nitrogen - it got lost in the clamp and we didn't continue. Soils are naturally acidic pretty light, we adjoin gravel quarries...
We had similar decision to make but AGA was oil with 135 boiler. Now have wood pellet boiler for heating and water. It's on RHI payment, without that I'd go with oil and you can resite it so no issue with piping etc. Cooking is a gas range with bottled gas, uses 2 x 48? a year. All...
How about mustard for a month, followed be a winter cereal grazed off with sheep after Christmas for tillering and weed control. I'm pondering similar decision on problem fields. I normally spring crop but no opportunity for weed control.
What was your starting base, and what have you been doing to increase levels please?
Indirect evidence should be adequate to prove the utility of OM ie. productivity, input use, profitability etc.
I did it more to have evidence to show what I was trying to achieve and hopefully an upward trend. Never know here when it might help to deal with some bureaucrat or even with marketing claims.
The best measure is the health and productivity of stock and crops.
What's the OM content of peat? Soils like the Fens in England and the Liverpool plains in NSW must have had a very high content when first farmed and still high now.
I've tested some fields this year and have results varying between 3.8 and 4.7% That's after in the teens of years in set aside...
