oh yeah, and a universal thing to do, add carbon to the soil, in this case, i bought 4kg of sugar and will cut a small hole in the bags and sprinkle it all over the garden area... carbon improves soil's nutrient buffering capacity by feeding bacteria that produce goop that has an ion exchange effect... i also thought about this too - to maybe put my cat's used litter, which will be full of ammonia, and scatter it sparingly over the ground to boost the nitrogen, since that also helps with green and growth
