is fertilizer extracted ?

Yes!\n\nComparison of the Ammonium Oxalate Extraction of Fertilizer for K2O, Method 983.02, with the Ammonium Citrate/EDTA Extraction, Method 993.31 \nNatalie F. Newlon \n\nThe direct available method for phosphorus in fertilizers, Method 960.03, is an Official Method for extraction of both P2O5 and K2O. Because K2O is much more soluble and easier to extract than P2O5, the conditions of the extraction procedure are set for efficient extraction of P2O5, and the extraction of K2O is, in effect, a bonus. In 1993, a modified extraction procedure, using an extractant of ammonium citrate/ethylenediaminetetraacetic acid (EDTA) solution, was evaluated for P2O5 and then collaboratively studied. This now-modified extraction procedure for phosphorus is Official Method 993.31, which is used extensively as an alternative to Method 960.03 for phosphorus because it is less labor-intensive. Method 993.31 was also evaluated in our laboratory for K2O extraction, but it was never formally collaboratively studied for K2O. To demonstrate the suitability of Method 993.31 as an extraction procedure for K2O, as well as P2O5 in fertilizers, Method 993.31 extraction for K2O was compared with Method 983.02, the traditional ammonium oxalate extraction procedure for K2O. A wide range of fertilizer samples was extracted by using both procedures. The t-test for samples containing <30% K2O had a t-value of 1.23 and a probability of 0.22, which indicates there was no significant difference in the results obtained by the 2 extraction methods. The t-test for samples containing >30% K2O had a t-value of 0.30 and a probability of 0.77, also indicating no significant difference. It is recommended that Method 983.02 be modified to include the ammonium citrate/EDTA extraction procedure as an additional option for extraction of K2O from commercial fertilizers.

KH2 is potassium hydride. This is not absorbable by plants. The phosphate is though (PO4).\n\nGo find yourself a good N-P-K fertilizer.

no, only to fertilize the eggs.

agricultural - as fertilizer\n\nIt also is able to be used as an explosive when combined with an oxidizer or accelerant. Timothy Mcvey used this in his bomb that destroyed the federal building in Oklahoma City. It is or was used in blasting for construction purposes as well. Its sale in quantity is now monitored due to its potential abuse, so I hope you're a farmer.

Depends how contaminated, contaminated w/ what and how much soil. \n\nMost counties have ag agents so start there and ask. Also soil testing is common for house building so call a local realtor or developer if you can't find one in the phone book.

Depends on the soil and what chemical process was used, but mostly plant nutrients. Very helpful website below.

hi...yes it is very true that while boosting crops with the use of chemical fertilizers  kill the fertility of the land in the long run. with every successive years u have to put more chemical fertilizer than u used in the previous year to boost the crop.\nBut if you use natural fertilizers like fertilizer made of cow dung and other waste material..will not only help to boost ur crop but also increase the fertility of land with every successive year.\nNow a days people also take help of "music" to boost the crop.\nAnd now it is  a proven fact that music does help in it. U have to just put speakers surrounding ur field and with regular interval play some music...and u will definetly get better results.\nGud luck.....

Even S--- Can be used as fertilizer so no you are not usless although you may be a peice of S---

In agriculture phosphate refers to one of the three primary plant nutrients, and it is a component of fertilizers. Rock phosphate is quarried from phosphate beds in sedimentary rocks. In former times it was simply crushed and used as is, but the crude form is now used only in organic farming. Normally it is chemically treated to make superphosphate, triple superphosphate, or ammonium phosphates, which have higher concentration of phosphate and are also more soluble, therefore more quickly usable by plants.

yes,but its just soil. earthworms are decomposers so they release nutrients back into the soil

Try the following companies:\n1. Reliance Group\n2. Nagarjuna group\n3. Paradeep Phosphates\nAnd all the pharma and fertilizer companies

Yes.  One of the main ingredients in fertilizers is Potassium, along with Nitrogen, and Phosphorus.  The human body uses potassium in a wide array of instances.  As an example, sports trainers typically suggest eating bannanas due to their high potassium content to prevent cramping during strenuous exercise.

WTF?....lol\n\nhttp://www.waksmanfoundation.org/labs/wisteb/extract.htm

sorry i dont really know, but a kit designed for extraction might work o.k. I'm guessing that you have tried regular high salt or phenol based methods and these have not been successful, perhaps repeating the extraction protocol on the resulting product may help.\n\nhad to laugh at the above answer, clearly has no idea but has got the hang of copy and paste!

not for an extended period of time. Poop has had all of the nutrients already filtered out and used by the body, it is just the waste product left over and has minimal nutritional value. It could possibly be recycled once or twice for the left over kernels that did not get digested the first time through.

Yea, the first answer is right.  Among many other factors, soils are made up of parent material that has decomposed.  It mostly depends on what kind of rock they came from.
