Hi,
so i have to do a science project and i am doing”How much fertilizer do you need to grow a healthy plant?”
so i am doing 3 plants and giving them different amounts of fertilizers.
then i measure on how much they grow.
and i am using a spray fertilizer
but i odn’t know what would be the “right” amount of fertilizer to give so i can do one lower and higher.
how many seconds should i give my plant to fertile?
oh and what would be the controlled,manipulated,and responding variable?
thanks!
There is no “right” amount for fertilizer. The correct amount will depend on the fertility of the soil you’re using.
I would do this:
1 radish with the recommended amount of fertilizer that is listed on the package. If you’re growing indoors, use the amount and frequency listed for “houseplants.”
1 radish with 1/2 the recommended amount of fertilizer that is listed on the package.
1 radish with no fertilizer.
Make sure you use the same soil from the same source (potting soil from a bag would be best). The unfertilized radish is your control. Make sure they get the same amount of light, heat, and water. If you want to do one “higher” I would use a fourth radish with twice the recommended amount of fertilizer.
However, if your question is “How much fertilizer do you need to grow a healthy plant?” then you probably want LESS fertilizer rather than MORE, because you’re trying to figure out exactly how much you can get away with and still have a healthy plant. Make sense?

Why are car companies/plants shying away from the traditional manual transmissions in automobiles?
I noticed Dodge Chrysler and a lot of car companies have that auto shift gear box. That’s so wack, compared to the traditional clutch. It just goes from side to side for gears, no more clutch. It’s really still an automatic to me because the clutch is gone. I see now why American cars are not being bought as much as foreign cars now. We (car consumers) want the traditional clutch to come back in effect. It’s the sportscar feel behind the wheel, you can’t feel it behind a Dodge Charger because there’s no clutch anymore, no matter how fast you make it. My favorite car is the Corvette, however, if someone tried to sell me a automatic I would not take it because it wouldn’t feel the same without the manual transmission. What’s your opinion on this?
The auto makers make cars that sell. While there is a small market for manual transmission cars, the great demand is for the automatics. There are many people in this world who can not drive a stick. Others can drive, but prefer an automatic transmission.
Water and fertilizer takes forever to absorb in my lawn. What can I do about this?
It sounds as if you have a drainage issue. Whilst the absolute way to clear this would be to dig your lawn up and install a drainage system, potentially involving pipes etc, there are other things that you can do that are less drastic.
As has been mentioned, aeration done at least annually, will improve surface drainage, and you can assist this by brushing in some sharp grit into the holes that you create. These holes and grit will help improve the amount of air around your grass roots, which will leave your lawn stronger and healthier.
You could also look at drainage around the edges of your lawns, perhaps lowering the soil a little, so that there is improved run-off away from lawn – you could also help with run-off channels, that will help some of the water to soak away – obviously working with, rather than against, any natural gradients.
As a temporary solution, you could dig a trench, that would collect a lot of water, potentially removing this by pumping, or hard graft lifting out by buckets etc. I’m guessing that the water table right now is also fairly high, such that water levels may only be slightly lower than the surface. There’s little that can be done, in this case, apart from getting rid of some of the underlying water, which could be hard work, as you’re partly going against natural systems. If your lawn is situated at a a very low level, then water will continue to drain in its direction, so improved drainage is the only longer term solution.
Otherwise, mow and remove any clippings always, and clear thatch on a regular basis, as this will absorb water at surface level and keep it lying around for longer.
Prolonged programmes that aerate and add drainage material do help with improving overall drainage. It’s usually impractical to completely dig up and replace the underlying poorly draining surface, but a perfectionist may seek that as a solution, if they have plenty of time and money of course.
Hope this helps. Good luck! Rob
Site-Specific Water and Fertilizer Application by a Wireless
Human urine makes an excellent high nitrogen liquid fertiliser for most plants. Dilute it 10 to 1 and pour it over and or round fast growing plants once a week; like vegetables, Green manure crops and sugar cane. Indeed just about anything that you want to push along rapid green growth
Studies indicate that each person’s waste fluids can provide enough nitrogen, phosphorous and potassium to grow a year’s supply of wheat and maize for that person. According to some studies, human waste can be an even more effective fertilizer than animal manure.
Urine, which comprises 90 percent of human waste, contains about 80 percent of our waste’s fertilizer value. It can be applied to field crops without treatment because it is generally sterile. By the way “fresh urine” does not contain any bacteria, unless the person has a urinary tract infection, so you could even use it to wash out wounds without causing any infections,
Human urine can be used as an alternative to chemical fertilizer to reduce pollution in air, water and soil and help avoid or control other environmental hazards which surface due to the use of chemical fertilizer, Human urine contains nitrogen, phosphorous and potassium at a much higher ratio than in commercial fertilizers and is environmentally safe to use.
If you want to use urine to fertilize your gardens, keep in mind that when urea becomes ammonia, it also becomes volatile and part of it strips into the air. Both ammonia and nitrates are also very soluble and if not picked up by plant’s root systems can enter groundwater with the irrigation water. So it would be best to keep gardens moist but not over watered, but these are similar problems faced by people who use other forms of fertilizers.
Problems urine causes
Most toilets use between 50 and 100 litres of water daily to flush away one to 1.5 litres of human excrement.
Urine is the largest contributor of nutrients to waste water, estimated as 50% of phosphorus and 80% of nitrogen.
The high level of nutrients in sewerage runoff leads to the consequent growth of algae, resulting in the lack of oxygen and the death of plants and animals on river, estuarine and sea beds.
Problems Chemical Fertilizers cause
Serious environmental hazards are often associated with the use of chemical fertilizers. In industrialized countries, for example, indiscriminate use of these substances has polluted water supplies. Dangerously high levels of chemicals have been reported in nearly one-fourth of Europe’s groundwater supplies.
Advantages of Urine Fertilizer
One advantage in using urine, as a fertilizer is that much of the urine is available in ideal chemical forms: nitrogen is in the form of urea (ammonia/ammonium which is present at concentrations of approximately 3.5 g/l), phosphorus as superphosphate and potassium as an ion. Urine is almost free from heavy metals – for example, cadmium – because even if we ingest them, they will tend to bind to the liver and kidneys, making the urine much lower in such contaminants than commercial fertilizers.
Urea outside the body quickly becomes ammonia and will be oxidized by special bacteria (called nitrifiers) into nitrates. All these ‘reactive’ nitrogen sources can be used to form amino groups for new amino acids, thus then being made into proteins. So make other steps to encourage the soil life in your garden, eg things lie mulching etc.
It helps conserve pure or town drinking water
Reduces the rate and amount of chemical fertilizer runoff into the groundwater and surrounding waterways
Reduces the amount of sewerage runoff
Reduces nutrient build-up in waterways and estuaries and oceans
Reduces your gardening costs, because of less reliance on buying chemical fertilizers.
Uses
Probably best used for non-edible plants, green manure crops and fruit orchards, though there is some usage being noted for edible crops. Apply in under fruiting plants, not onto foliage and fruits.
In a Hydroponics set-up, use it diluted, probably at a ratio of either 10- 20 to 1(water- urine), but keep a close eye on both the ph level and the level of individual salts of the mix in the nutrient storage container.
Dilute urine is also a good additive to a compost pile. Urea also helps break down lignin, accelerating the decomposition of woody materials. On the other hand, urine from somebody with a urinary tract infection or from unknown sources should probably be pasteurised or put in a long-term compost pile (of a year or longer)
before it is used on food crops.
When using a urine fertilizer in container plants, a 10:1 (water: urine) ratio can quickly burn plants in medium to small containers because of the salt and urea build-up, even at a 15:1 dilution rate is very strong for the medium to small containers. While at 20:1 you can use it more frequently (once or twice a week) with good benefits and little danger.
Unfermented urine can supposedly be sprayed as a fungicide. Indigenous people in southeastern Mexico claim that the use of urine as a fungicide was a traditional Mayan practice. However there needs to be a lot more research as to the validity or not of their claims.
While in Korea, they spray the undiluted urine as an insecticide, but again I do not know of any research to prove or disprove their claims.
So why not get out there, and help the environment by assisting in reducing the nutrient flow into the natural ground water and water ways, while saving yourself a bundle in fertilizer costs.

Use Fertilizers Sparingly – Washington Waters, ours to protect, public service announcement
i want to add some to my bamboo.
do i have to wash them first?
do i add the water first or the crystals?
i put some in a small glass just to see how goes. the problem is i bought them in colors but they just became transparent now! is that okay??
You should be able to add these without any problem, as long as what was used to color them was non-toxic. I’ve purchased aquatic plants rooted in this.
You shouldn’t need to wash them.
I would add the water first, then add some crystals to the water. The recommended mix is 2 ounces of dry crystals to at least 1.5 gallons of water, but you won’t need that much of either if all you’re planning to do is fill a vase for the bamboo. Just remember that the leaves shouldn’t be in the water crystals, but above the mix, and that the mix doesn’t provide any nutrients, so you’ll need to add a fertilizer periodically.
Fertigator Mojo Feeder Tops The List For Fertigation Systems
Those looking for a fertilizer injecting system otherwise known as fertigation have a couple new cool little systems to contemplate about. Fertigator has always been one of the best manufacturers of fertigation systems and technology, but the Fertigator Mojo feeder tops the list as the best fertigation system we have found available to date. The benefits of the Fertigator Mojo are huge. The system supplies grass and plants with small doses of fertilizer on a consistent basis through a pre existing irrigation system. This allows the plants to thrive on in a nutrient rich environment. The Mojo will make your yard the neighborhoods idol. The system and fertilizer is also much cheaper than calling out a pest control operator that charges $60.00 a visit to spray down your yard once a month. Fertilizing your yard with the old out dated method results in over feeding as the plants use up the nutrients during the first couple days after treatment. After a week or two the lawn endures a time of near starvation, until the next chemical treatment. This process is repeated month after month and is very stressful on the plants which causes problems down the road. The system works by reading the sprinkler system timer to determine when and how much fertilizer should be injected. The system is very precise so there is no over spraying possible as in some other systems. The fertilizer is pulled from its container and injected into the proper valve for distributor on the yard or plant material. Each zone will be programmed to deliver exactly the right amount of fertilizer for that zone. Injection rates can vary from 0 to 19 pulses for every two minutes to eight minutes. All this makes the Fertigator Mojo by far the best fertigation system on the market at a reasonable price as they go for about $299.25 on average, some of the other off brand systems with less options we have found to be a headache and can cost as much as $1000.00 for a single home unit.
