Nitrogen: Friend or Foe? by Dawn West, All About Lawns Columnist Nitrogen -- without it your lawn's growth slows, its color fades, it thins and withers. But with too much of it, the story is just as bad: your lawn burns, turns brown, and dies.

Nitrogen is used by plants for lots of leaf growth and good green color. Phosphorous is used by plants to help form new roots, make seeds, fruit and flowers. It's also used by plants to help fight disease.

Soil Nitrogen Content I had my soil tested and was told that it has poor nitrogen content. How can I build the nitrogen content in a safe, organic way?
| |
TOTALLY PRACTICAL: Stop Nitrogen Drawdown Mulch in the garden is a vital ingredient for suppressing weeds and reducing evaporation. Some mulches, however, can cause problems with nitrogen deficiency.
| |
Nitrogen can really "green up" a lawn. However, some forms of it are very mobile and can leach through the soil to contaminate the water supply if not properly applied.
| |
Nitrogen helps plants make the proteins they need to produce new tissues. In nature, nitrogen is often in short supply so plants have evolved to take up as much nitrogen as possible, even if it means not taking up other necessary elements.
| |
Nitrogen is a mobile nutrient it is in constant motion. Nitrogen applied to the soil can be used by plants, washed off the soil surface, lost to the air as a gas, or leached through the soil).
| |
NitrogenVery important plant nutrient to help plants to develop foliage and stem growth. It is the main ingredient of lawn food and lawn greeners. A silly trick is to write your name on your lawn by sprinkling urea in the shape of the words.

Nitrogen (N)--promotes development of new leaves Phosphorus (P)--aids in root growth and blooming Potassium (K)--important for disease resistance and aids growth in extreme temperatures Sulfur (S)--contributes to healthy, ...

NITROGEN CYCLE -- The transformation of nitrogen from an atmospheric gas to organic compounds in the soil, then to compounds in plants and eventually the release of nitrogen gas back into the atmosphere.
| |
N Nitrogen produces strong, lush leaf growth. but used to excess it can delay flowering and cause a soft floppy plant. P Phosphorus makes for strong root development and balances the nitrogen in strengthening top growth and excess can stunt a plant.
| |
The nitrogen contained in grass clippings removed from a lawn almost equals the recommended application rate for healthy turf (about 5 pounds of nitrogen per year per 1000 square feet).

NPK Nitrogen, Phosphorous and Potash; the three main food elements necessary for plant life. Nitrogen is required for foliage and growth, phosphorous for flowers and potash for roots. Nut A hard and single- seed fruit found in many trees and shrubs.
| |
Surplus NitrogenMany gardeners waste nitrogen and manures; farmers do otherwise. Farmers only need a quarter to a third of nitrogen to mix with an inch of compost, horse, or cow manure.
| |
Too much nitrogen fertilizer after mid summer will keep a plant in a growth state when it should be going into dormancy. Warm weather spells during the winter can break dormancy in a plant that has gone dormant.
| |
Manufactured nitrogen fertilizers are normally made from petroleum or natural gas. Being relatively high in nutrient content, smaller volumes are required, and the fertilizer can burn if over applied.
| |
Green matter- nitrogen rich organic material, like lawn clippings and kitchen scraps (no meat!)-is then added to the brown matter at ratio of 1:1.
| |
If additional nitrogen is needed, apply approximately 0.15 pounds actual nitrogen per 3 bushels (3 3/4 cubic feet) of carbon rich materials such as leaves. Table 5 lists estimated amounts of various nitrogen sources to add.
| |
The 'big three' are nitrogen (N), phosphorus (P) and potassium (K) - the letters in brackets are their chemical symbols. Think of these as 'meat and two veg'.
| |
Feeding Use a high- nitrogen liquid fertilizer. Mix it 1/4 strength and feed the plant weekly from mid- spring until late summer. Discontinue feedings in winter.
| |
Plants will not be able to utilize nitrogen and other food properly. Ultimately, the very process of photosynthesis will be adversely affected to such a degree that plants will weaken and die. They will give way to fungus and other disease.
| |
Cultivate a half cup of low nitrogen fertilizer such as (5-10-10) into the soil when the stems are about 2 or 3 inches high. Use care not to damage the roots, and try to keep the fertilizer from direct contact with them.
| |
Elements most necessary to them are carbon, hydrogen, oxygen, and nitrogen, with various mineral substances present in the soil. Carbon is the most abundant.
| |
N-P-K ( Nitrogen- Phosphorus- Potassium) are the 3 most abundant ingredients listed on every fertilizer label. They are always in this order. You will see them on the label as three numbers.
| |
Maintain moderate to high nitrogen fertility during periods favorable for dollar spot development.
| |
That blue stuff (and most of the fertilizers available today) rely on water soluble nitrogen as their primary ingredient, and that is not a very good thing for our garden or the environment.
| |
Clippings add nitrogen back into the soil and cut down on the need for fertilizer.
| |
Remember, however, that the more woody your mulch, the more nitrogen will be used by the soil bacteria to break it down -- nitrogen your raspberries need.
| |
To prevent nitrogen deficiency in corn, which would result in premature yellowing of leaves and smaller ears, scatter fertilizer along the row or side dress when the plants are about a foot or two high.
| |
(Check your soil test results to see how much you need.) Slow release sources of nitrogen applied at planting can meet nitrogen needs for the entire season.
| |
The bacteria and other microscopic beasties in the soil require nitrogen whilst decomposing raw material, and they get it from the soil. If too much of the raw kitty litter etc.
| |
For most blue grass lawns, two to five lbs of nitrogen/1000 sq.ft. is sufficient. Apply this in a fertilizer balanced by phosphorus and potassium.
