Didin nitrification inhibitor

Loads on the internet. Did a lot of work on it many years ago in relation to composting, but never actually put it into practice. Quite a lot of work been done over the years as an admixture to manures.

This is an interesting synopsis;

I have actually still got a few tonnes of clinopitilite in bags, left over from the work we were doing at the time. Always thought it was a topic worth further exploring. Including its potential use in AD plants that have too high an ammonia content. As part of our gasification plant we now produce a biochar by product, which has intriguingly similar properties in relation to abdsorption into micro pores.

There was mention at the annual Frontier beano this week of mandatory inclusion of urease inhibitors in urea fertilisers. Yet another cost increase that we’ll be expected to take on the chin, and I wouldn’t be surprised to find that anything that disrupts urease also disrupts soil biology in a negative way.

Should also mention that their soils guy also strongly recommended that even with an inhibitor added farmers should apply urea in at least 3 or 4 splits, and that a single big hit was highly detrimental to soil.

There are two types of inhibitor I think. Those like Didin-dicyandiamide- which quite correctly interrupts the 'soil biology' so modernly quoted-the nitrosomas bacteria I think, and provides slow release as the soil warms. Using this type you can chuck the whole lot on in early March & done. It works, we did it here for many years, but price against urea, slow application-600l/ha+ and Didin at £20/ha made us change to bulk urea & trailed Kuhn pneumatic. But urea has issues in dry times.... The other type, which we are using this year is the addative to reduce volatilisation in dry weather. SKW Piagran product-£20/T premium over base and incorporated through the granule as formed, not a coating that can shell off like Koch.We share the spreader so when go-able, the machine goes to get round. So a bit of insurance against having to go in a dry time, rather than waiting for rain, is worth it. Operational efficiencies of the product expected also, up towards that of AN-so will monitor & possibly shave rates in the future.
