Understanding Phosphorus

With all of that in mind, what are the symptoms that come with a phosphorus deficiency? Stunted growth could be from any number of different nutrient deficiencies. There are some ways to be able to tell and distinguish to give the gardener an opportunity to compensate for any potentially fatal crop or soil deficiencies. Plants that are deficient in phosphorus are stunted in growth as well as they typically have a very unusual dark-green coloration to them.

There could also be the development of anthocyanin pigments that give off a reddish-purple color in the cases of extreme phosphorus deficiencies. If your plant is exhibiting these types of discolorations, then the time to act is right now if the plant is to grow to its potential. These different colorations could be natural from your plant species, however. A few more symptoms to look for include a significantly lesser leaf expansion and a much smaller leaf surface area. Less leaves on the plant could also be the side-effect of low phosphorus levels. Also, be sure to check that the root mass looks appropriate and strong as lessened root growth is a very strong indicator of a low P level in your soil. Some of the other effects that a lower level than needed of P could include delayed maturity, poor quality forage, fruit, vegetable and grain crops, as well as a much higher sensitivity to plant illness.

Keep all of these factors in mind as you watch the growth of your plants to be able to diagnose a deficiency of phosphorus and take the necessary actions to be able to compensate for such a scenario. We are proud to offer Liquid Bloom and Mag-Pro to be able to help combat these devastating effects which a phosphorus deficiency has against all plants."

The importation of P indirectly from poor countries to feed rich ones IS a major issue. Growing in Africa to feed Europe.....NICE

Aside from that, 80% of know deposits of high grade P are in Northern Africa.

I can't believe it, finally a thread that actually belongs in the Advanced section!!!

Cheers OP.

major issue? i think most would argue the consistent instability, corruption, and war within most african governments and countries is more of a "major" issue vs the mining of a mineral. but we all have different priorities

One in the same. The exploitation of one people for benefit of another. European owned farms growing and packaging food in Africa to feed themselves in Europe is no different. No worries there is plenty of Food aid to go around right?

Sounds to me like you have just come around here to start shit with me? For what reason if I may? Did you watch any of the videos? If not, than move along without commenting.

Thank you sir

I cringe while listening to people talk as if the farmer is the sole reason but this video seems somewhat balanced. Phos will start wars soon.......if we don't figure it out.

It IS figured out, just no one is listening.

We have no phosphorus deficiency in our soils,
we have a deficiency of microbial life to mine it.

Nothing a few applications of a thin layer of GOOD compost, combined with a few tweaks to farming methods (no-till, perennial ground covers..) can't resolve.
