Adding phosphorus to soil without bonemeal?
After a couple of underwhelming years on my veggie patch, I've had my soil tested and found that it's very deficient in phosphorus. A quick Google tells me that blood/bonemeal is an easy way to remedy this. However, I already tried this a couple of years ago and unfortunately my neighbour's cat found it absolutely DELICIOUS, to the extent that she was literally eating the soil and even covering everything in chicken wire couldn't stop her.
So, any alternatives that do the same job but a) are still safe to put on soil where edible plants grow and b) won't encourage cats to make a mess?
