How long do these organic fert's last in the soil before you should reapply?

Blood as a Nitrogen source is fast compared to other organics. Like synthetics, the "feasible residusal" is probaly from 4-8 weeks depending on soil, amoint of precipitation, & growth expectation.

Bome Meal is extremely slow. If adequate quantities of calculated P were applied initially, you may not need anymore this year at all. Not all that P will release in our lifetimes. Even the most highly soluble synthetic P source (DAP) will last about 50 years when soil incorporated.
