Is there a way to make my own fertilizer? is there a site or a store i could go to and get the raw ingredients for a CHEMICAL fertilizer. i am doing this for orchids, so compost is out of the question and will not help me at all. i need to design three specific types of non-urea nitrogen fertilizers 30-10-10 30-30-10 10-30-30 i would buy them but anything i find similar to those have urea nitrogen which inhibits orchids from absorbing certain micronutrients. i'm basically looking for a build-a-bear workshop but for fertilizer instead of stuffed animals. also, if anyone knows where fertilizers like these with trace elements of iron, manganese, zinc and other such micro-nutrients pre-made with NO urea-based nitrogen in them, i would love to know where to find them. thanks ugh what is it with you people (for those of you that gave me legitimate answers i'm not speaking to you)? IT'S AN ORCHID!!! it's not in soil, it's in bark. the bark CANNOT hold compost or manure and i'm not putting chicken sh** or bat sh** or cow sh** on my f***in house plants. not only would the BARK (NOT SOIL) that my plant is in not be able to hold it and therefore not deliver any of the amazing benifits to my orchid, but my house would stink. I realize orchids grow in the rainforest with no chemicals. but that is in NATURE. birds poop on the trees and decomposing matter gets stuck in the crevices of bark on the trees or rocks where they live and the roots are able to pull those nutrients along with the trace minerals in rain water. I however have no desire to capture rain water as standing water in your yard promotes mosquito larvae. i'm not seeking knowledge, i know all this, i'm seeking information, which ARE two different things. don't answer if you're unknowledgeable. I am very knowledgeable about compost and its long-lasting slow-release benefits over chemical fertilizers. IN DIRT, where it can sit for a long time and the nutrients can be released slowly. but my orchid is not in dirt and i shant be covering it in droppings of any kind, therefore i need to substitute chemicals. I was merely asking if anyone knew of the fertilizers i needed, or if there was a place to design a water-soluble fertilizer using non-urea based nitrogen.

How do you separate sand, copper sulfate and urea? We're given a mixture of sand, copper sulfate and urea (a valuable fertilizer) in a film canister We have to separate them and find what weight of each substance was present in the mixture Here is some information about the 3 substances: Urea: Colour: white. Soluble in both water and meths Copper sulfate: Colour: blue. Only soluble in water Sand: Colour: yellow. Insoluble in both water and meths You may have 30mL of meths and 30mL of distilled water At the end of this (since we are going to do this in class) you should have the copper sulfate, sand and urea separated and dry so they can be individually weighed. There will be a prize for the person that is closest to the weighs that have been measured into the sample jar. If ANYONE knows how to separate this mixture please write down the method All answers appreciated Thank you

Algae help in controlling ammonia in a tank? i just came across this: "algae (GW form) will flourish off of the ammonia/ammonium and phosphate, remembering that algae can consume phosphate easier than plants because of their thin cell walls, the algae uses up the ammonia/ammonium and phosphate, but it doesn't go away...because algae can quickly switch which nutrient it scavenges...it moves to nitrates. " source: http://www.aquahobby.com/articles/e_freshwater_algae.php Is it possible to keep algae along with vegetation in a tank to check levels of ammonia and other "toxins" which are other wise harmful to the fish. i have a common pleco and im sure that along with proper nutrient and light control i can check the amount of algae i need in the tank. I have already collected a sample of green algae from my garden and added it to a seperate bowl of water along with phosphate fertilizers and a little urea to grow it quick(few hours to a day maybe). i intend on transfering the algae...little by little to the main tank(ensuring that no water containning the urea,fertilizer,etc comes along) to the main tank.The algae looks fine and green and mossy so far. however i want to be sure it is not toxic and wont kill my fish. cna anyone please advice with regard to the above.

Air conditioning system : why the equalizing line is icing? Its a Carrier water cooled condenser type, chilled water acu system for a Dehumidifier system. Used at the urea fertilizer bulk store. System not running.Suspected TRV defective. Ordered to change new filter drier (block filter) and change new TRV (TRAE30HW90 6A ), purge the affected area. charged in gas-R22 and run system. Continue to charge in gas to LP 60 psi and HP 225 psi, load was 38.5 amps. Require 41 amps @ LP 70 psi, HP 250 psi approx. nominal ratio. At 38.5 Amps the equalizing line started to frost (icing). This shows that there is liquid flow to the return line. At this point the amps drop to 34 amps and LP 38 psi in a period of 20 min.The other system combined to the same chiller is running good with HP 240 psi, LP 68 psi @ 41 amps. I also tried charging up more gas but the gas did not want to go in. Continued to run system as it is and there was no change. Whats the remedy to this condition? Tks, Allan
cold starting compost pile tips? It is winter in the NE with temps around freezing. A month ago I chopped up my first garden and the collection cooked for a bit then stopped. Since then, I have chopped up all the leaves "leaving" a damp pile around 4' diameter. The leaves weren't cooking so I added in some Urea fertilizer ( 45-0-0 about 3lbs) for nitrogen and wet the mix while stirring. Is it too cold to start cooking? My efforts aren't producing much heat but the leaves are very slowly turning black. Did I add enough nitrogen? The previous little cooker did not stink and I didn't add the entire 5 Lb bag as I wanted to avoid a problem. Would it make a difference if I could jump start it with some heat? I am thinking of reflected sunlight, or greenhouse effect... I would not simply want to add heat for the entire process though. It would eventually have to be self sustaining. I am also thinking that a winter compost pile may require an insulated container, but this would only work if I could get it started in the first place.

L/min. Carbon dioxide at 223°C and 41 atm flows into the reactor at a rate of 600. L/min. What mass of urea is produced per minute by this reaction assuming 100% yield?
help...........!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1? i honestly have no idea how to do it, please shoe me and tell me the answer. thanks Urea (H2NCONH2) is used extensively as a nitrogen source in fertilizers. It is produced commercially from the reaction of ammonia and carbon dioxide. 2 NH3(g) + CO2(g_------heat and pressure------> H2NCONH2(s) + H2O(g) Ammonia gas at 223°C and 90. atm flows into a reactor at a rate of 690. L/min. Carbon dioxide at 223°C and 47 atm flows into the reactor at a rate of 600. L/min. What mass of urea is produced per minute by this reaction assuming 100% yield?
chem help...ideal gas law? Urea (H2NCONH2) is used extensively as a nitrogen source in fertilizers. It is produced commercially from the reaction of ammonia and carbon dioxide. 2 NH3(g) + CO2(g) H2NCONH2(s) + H2O(g) Ammonia gas at 223°C and 90. atm flows into a reactor at a rate of 690. L/min. Carbon dioxide at 223°C and 47 atm flows into the reactor at a rate of 600. L/min. What mass of urea is produced per minute by this reaction assuming 100% yield? g/min please show me how to get the answer b/c i need to study for my exam thanks for the help 2 NH3(g) + CO2(g) --heat and pressure----> H2NCONH2(s) + H2O(g)
