Why does human urine kill grass

Open Access Journal of. Research Article Volume 2 Issue 6. Sample preparation Soil Ten kilogram 10Kg of soil sample was measured and mixed with water to wet the soil. Urine The urine samples were diluted separately with the aid of a calibrated measuring cylinder at different concentrations for both male and female samples ranging from 50, , and ml respectively i.

Planting of Seeds Seven 7 seeds of Zea mays were sown in each of the prepared pots for both male and female urine samples respectively Growth parameters Plant height The height of a plant was measured with meter rule every two weeks.

Number of leaves A plant was randomly selected for all plant and the numbers of leaves per this plant were counted every two weeks and the average number of leaves was calculated for each plant per treatment. Leaf area One plant was selected for each of the treatments. Stem girth This was measured using a thread which was later transferred to a meter rule to get the readings. Quantitative phytochemical analysis The leaves of Zea mays were harvested at the end of the experiment.

Growth parameters Two weeks after planting The result of the growth parameter after two weeks of planting is presented in Table 1. Practical Guidance on the Use of urine in Crop Production. Jemba PK.

Though one particular pee might hardly make a difference, just think of the effects from huge numbers of conscientious pee-ers!

Grist thanks its sponsors. Become one. I am delighted to report that with your question, I can finally start a folder entitled Creative Ways to Battle Invasive Species. First, we discussed feeding them to our dogs ; now we turn to peeing on them. That, and writing me a question is akin to joining my circle of trust. For plants, human urine can be a blessing or a curse, depending on amount, concentration, soil composition, and plenty of other variables.

That yellow stream is mostly water, but it also contains nitrogen, potassium, and phosphorus , which just happen to be the key ingredients in garden fertilizer. Knowing that, then, is it any wonder that some gardeners have been using it for years as a treat for their tomatoes, and that go-getting researchers have experimented with large-scale pee-collection projects in lieu of chemical fertilizers?

A group of Finnish scientists grew bigger beets with sprinkled urine than with mineral fertilizer. Apparently proving a wee change can make a big difference. There is one thing: salt. We all excrete some salts Westerners in particular because of our diets , which harm plants in high enough doses.

Would peeing on invasive species help drown them out? You can attempt to eradicate some invasives by consistently peeing on them, but it will take a lot of pee. If you and a bunch of friends teamed up on the same plant, making sure to saturate the roots, well, maybe Steinfeld estimates about 6 cups of undiluted urine in one day would do the job on one dandelion.

Your Robot Wrangler is well equipped in handling yellow patches and will renew your lawn in no time. Residential lawn care is a time-consuming business.

Call for a quick estimate Replant the area with urine-resistant grass. Kentucky Bluegrass and Bermuda are the most sensitive to urine, while Ryegrass and Fescue are the best for dog urine.

Use a lawn repair treatment. Dog urine lawn treatments use organic enzymes and soil cleansers to flush the salts out. Fertilize and water.
