Hi guys, i have an allotment and am worried that the quality of the soil has deteriorated, we have rotavated in loads of well rotted horse poo and used chicken manure pellets and grown green fertiliser which we turned in to the soil.
The crops last year did okay but not as well as I had hoped.
Can anyone tell me what I could use to improve the nutrient levels in the soil, which is a mix of reasonable well draining loam and heavy, wet , claggy clay type stuff.
Has the recent deluge washed out what was there. I am not a big fan of chemicals but would compromise my principals on this occasion.
All advice great fully accepted. Thanks.
