What is the best way to test soil in a vegetable garden ?

I use the test kits they have at your local nursery. They vary in price and they are accurate enough to know if you need to add any amenities. They work like a charm for me. By the way, what vegetables are you going to grow?

Well.... you can make a universal indicator by heating up red cabbage in boiling water...remove the cabbage and the solution that remains will be a different color when placed in solutions of varying pH.  You would have to add water to the soil sample to mix it with the indicator.

If it is just about vertical infiltration, you can use Green-Ampht equation or simply Darcy's law if the soil is saturatted.\nThese require, soil properties such as porocity, field capacity, hydraulic conductivity and rainfall intensity.\n\nFor more realistic and regional studies, you can use \nWater balance method, Penman-montith method, \nThe above require all sorts of meteorologic information including solar radiation. The water balance method is much simpler but you need a long-time record. P=M method is very complex so you'll be better off to use HELP 3 model that kind of automates the process. This DOS based model can be downloaded at USGS website.

i would set up the project to include 3 different types of plants, and 5 different levels of fertilizers.  pick 3 very different types of plants that grow in different climates or conditions.  for the amounts of fertilizers, for each of the threet types of plants, put no fertilizer, this will be the control.  then put 3 varying amounts of ferilizers on the 3 of each type of plant.  i recommend 1%, 5%, and 10% (but it depends of the type and concentration of the fertilizer) of the soil quantity be replaces with fertilizer.  for the 5th of each of the three types of plants, put in 50% fertilizer, this will be your sample that shows what happens when fertilizer is totally overloaded.  i can give you a lot more ideas if you want to go in depth.  otherwise, this should give you a good start.

gather some leaves. put them in a metal drum after wetting them. wait until the leaves are decomposed - what remains is a compost fertilizer

Soil saturation. Locations and soil types are constants.

any lawn fertilizer you may find in your parents garage

Stick em in some arm fertilizer. But be patient, these things don't happen overnight.

The best test is a streak test. If you are not familiar with this, it is when you rub the mineral across a piece of unglazed porcelain plate or tile.\n\nIn a streak test the gold will leave behind a gold streak while pyrite will leave behind a black one. This works, trust me, I know. All you need is a piece of unglazed porcelain.\n\nYou said earlier about rubbing it across the skin. I have never seen this work however some cheap jewlery is made of pyrite & will leave the fingers, etc. black looking. That is after you wear it a while.\n\nGold is very dense for its size. Pyrite is not nearly as dense. You could do a density test by displacement in water but I assume from what you told me that the "gold" is in a matrix.\n\nPyrite is usually found as a mass of cubic crystals. Sometimes they take on the appearance of a nugget b/c the cubes are very tiny. Gold will not have these cubes.\n\nGold is sometimes found in quartz veins. If you have a chunk of quartz it is possible that there is some gold in there.\n\nGo with the streak test & let us know what happens.\n\n:)

Domestic Waste:\n\nYou can dig a  3 feet pit. Put all the waste add water again put the  waste add water.let is wait for 5 weeks.You dig back you will\nhave good manure for your plants.\n\nIndustrial Waste:\nDepends on whether it is hazardous or not.So we have to leave it to professionals Or one should become a professional before handling such a thing.

How much time do you have?  If you have a few weeks....\n\nGet 5 of the same type of plant.\n\nMake sure they all have the same conditions.  Same type of soil/amount   Same amount of light/temp.  If using lamps, make sure they get the same amount of lamp time.\n\nThe goal is to keep all conditions the same aside from the one variable you will be testing... \n\nSo on to the variable.  Pick 5 different substances that you will give them for fluids... IE...\n\n1. Water  2. Soda   3. Bleach   4. Miracle grow or other plant food mixxed with water.   5. Orance juice.\n\nOkay.  Water will be your control group.  You will use this as a base line to compare all of the others to.  You can of course pick whatever you want for fluids. Those are just some ideas pick whatever fluids you want.  Always make sure to have a control group (the one with water) so you have something as a base line.\n\nGive them all 25 milliliters of the subtance each day. The amount you give them depends on what plant you pick, and its size, adjust accordingly. Make sure to feed them at the same time each day.\n\nBefore you start, write down your hypothesis.. \nHow do you think each plant will do? and why?\n\nTwice a week write down how the plants look.\nHow much they have grown.\nThe plants overall health.\nAlso, write down anything else you have noticed. i.e change in color, a plant dying.  \n\nThen compare it with the plant just getting plain water.  It is doing better than the control?  worse?  same? \n\nAt the end of each week make a theory on how you think the plant will do over the next week.\n\nMake sure to factor out all variable, and keep everything aside from the substance they get the exact same.\n\nWhen done with the experiment write a conclusion.  Was your hypothesis correct? What were you right about? What were you wrong about? How did each plant fair?  What could you have changed to make the experiment more accurate??  Did you do anytyhing wrong? ie mistakenly change something?  If you repeated the experiment, do you think the results would be the same? why or why not?\n\nMake sure to fully explain all of your statements. Charts or graphs of the results are always nice.\n\nThis would work the best if you started them from seed, but you prob don't have that kind of time span.  \n\nIf this is to childish of an experiment, maybe do a plant stem grafting experiment, or a cross-pollination between plants of the same species. i.e make a hybrid plant from 2 differnt types of tomatos or different flowers.

if you experiment with potted plants, it is likely, that far more nutrient is in the soil, so you will observe nothing. (only some plants do not tolerate too much watering, too cold water, chlorinated water - fresh from tap, ) I suggest you go for hydroponia (plant in water and nothing else) so that you can get somewhere. I also suggest you use seeds so that you have larger number of identical material - lets say each experimental variant will look like three-five  dishes with 50 cress/mustard seeds each.  (TO RULE OUT CHANCE!!! ) you can try different waters and your experiment will still take up the space on one window sill or small desk. You will observe different coloration, growth rate, as the plants will experience lack of nutrients (you can also try different fertilizers, different ammount of it, do chemical tests with your waters). I dont recomment larger seeds than that, because then you will have much nutrients in the seeds themselves.\ngood luck

get yourself a bio-cycle system or a worm pit. serious, they have them in oz. it's a pit of worms that processes all of the junk (food, faeces) and puts the left over clean fluid under the garden beds. the ultimate  compost heap

The test that I'm familiar with is thin layer chromatography.  This process uses the polarizability chararacteristics of each pigment in a plant sample.  In my experiment, spinach leaves are grounded and mixed with anhydrous sodium sulfate and sand.

any plant waste ..... well u can use the vegetable waste in producing cheap and environmental freindly manure in your kitchen by throwing them into teh sand pit and covering it up after a month or so use that sand as manure
