manure

Hi
A few years ago I put manure which had aminopyralid in it on my plot, with disastrous consequences. Since then I have tried to make as much organic compost as possible, from my garden at home and from the allotment.
I grow far more leafy veg than I need, such as perpetual spinach, which regrows well and is relatively disease free. Comfrey, nettles, torn up unprinted cardboard all help to bulk it up.

However in all honesty I am still struggling to get the soil as enriched as it would have been by the application of manure, so if anyone has found an answer to this I would also be very interested to know.

I wish I could find a local farmer who has cows,

I'm assuming it's emphasis on cow manure is because of the abundance of cows in India. The video labels it the "Vedic" method.  Chicken, rabbit, horse, they all work well.
Ivor is right. You have to replace what you take out when you harvest. My plants did well without manure or fertilizer but the beds were new at the time. If I were to keep that up year after year I'd start to see a significant decline. This fall I'll be planting crimson clover as a cover crop. Have you looked into green manure at all?

As mentioned, compost or digging in green manure are a good alternate for breaking up the soil structure and adding vegetable matter (for sandy soils, this helps to retain water) - all the right ingredients to encourage natural soil flora and fauna (worms) to flourish which digest the material to provide nutrients that plants can take up.  Neither manure or compost are really about providing immense amounts of NPK but do release a lot of essential micro nutrients that plants need for healthy growth - which is why using leaves from those plants with deep roots such as comfrey are ideal compost material as they take up nutrients that other plant roots can't reach, which break down and released into the compost.  Bear in mind that no matter what you use, during this process some of the nitrogen are taken up by the soil bacteria and fungus as they multiply but when their food source becomes scarce, they die off releasing the nitrogen back to the soil.  Another reason why digging it all in autumn is probably better than just before planting in spring.  If you want to improve the nutrition of soil, why not start up a wormery - this is more or less doing the same thing as filling up compost bins with kitchen waste but probably more efficient and a rich source.

Seaweed is probably a v good alternative if you can get loads and often. I use that a lot.

I also pile  a load of manure (local horse stable owner drops it off at allotments free) on over winter and can see the difference. An added bonus is weed suppression.

seaweed is very good

I might question the weed suppression - horse manure probably has more weed seeds than any other manure that I know of!

You may have a point about the weed suppression/causing properties of horse manure. I've found it does help keep things under control in the raised beds though, and what is produced weed wise is quite easily hoed off...when I get round to it!

I also use mushroom compost, can get a load delivered for very little cash, which lasts all year.  And free mushrooms!
