Seedmeal- Enough Nitrogen?
I converted the recommended nitrogen (per soil test) to a seedmeal based fert. using soybean meal and alfalfa meal. I converted and measured so that the amount of N present in the seedmeal is exactly that of what is recommended I applied.
I'm wondering, though, is there some other variable I'm looking over? Will my seedmeals be able to provide sufficient N or does it need to be supplemented with another source? |

Just because N is present in a raw organic input doesn't mean that the N will be available immediately for your crop. It may take the entire season for just a percentage of that N to be available. The plant based nutrients are tied up in proteins in the meals and are released as microbes break them down over time. It's a good long term solution to increase plant available nutrients in the soil but if you need more N availability organically in the short term then supplementing regularly with a liquid Fish hydrolysate or Fish emulsion is an effective solution.

Some people put bloodmeal in the planting hole, what do you think of that? |

Blood meal is OK too as a fairly rapid source of N. The rate of mineralization of organic N from both plant and animal sources depends on soil temperature mostly, warmer soils in summer are optimal for the microbes to multiply and do their job. |

I am using blood meal this year as top dressing. It is my understanding that seed meals and feather meals are more of a sustained but slow release source of N.
I am not sure that accuracy is really required with measuring. I am sure that you will be fine. |

Will probably just add a bit of low, organic all purpose to the planting holes
