But you won't be allowed to put it on in the autumn because they've banned it!!!To a greater or lesser extent sludge gets hauled all over the country too... if eventually all sludge went through the process it would end up being transported no further than sludge whist being perhaps 40% lighter without the water content. For most farms the sewage works is a lot closer than the docks too....
I would expect properly calibrated twin discs should spread the pellets at least as accurately as a muck spreader can spread sludge, even if that might mean putting it on to stubbles at 12m rather than 24 or 36...
We really can not afford to pee P and K out to sea, we do need to recover as much as possible.
However I do share the concerns of many commentator here. The NPK is all welcome but its all the other difficult chemicals and microplastics that give concern around any applications of recovered sewage be they sludge or pelleted sludge. Independent analysis is really important.
I do like the suggestion that if ST are confident in the safely profile the best route would be give the product for free to farmers in catchments with water quality problems...
Growers should expect to pay for high purity crop nutrients but landowners should be paid and paid very well when providing a commercial waste disposal service.
No nitrogen applications of any kind unless there is a crop need, and that means osr only.
Which with insecticides useless is diminishing in area rapidly.
