Mushrooms need more soil nitrogen than grass does.

Furthermore, the plant can raise the pH of the soil and affect soil nitrogen levels.

He found that microbial activity and soil nitrogen increased, both indications that the bugs were decomposing.

This plant acts as a nurse plant for other species, providing shade and increased soil nitrogen for young growing plants.

Its nitrogen-fixing abilities (which increases soil nitrogen) and its use as an animal feed greatly improve agricultural efficiency.

In excess, denitrification can lead to overall losses of available soil nitrogen and subsequent loss of soil fertility.

The effects of fire on soil nitrogen associated with patches of the actinorhizal shrub Ceanothus cordulatus.

Legume: A plant, such as the soybean, that bears nitrogen-fixing bacteria on its roots, and thereby increases soil nitrogen content.

Maize cultivation draws very heavily on soil nitrogen, while beans are very effective at returning atmospheric nitrogen to the soils.

If so, that would make the mosses - which with more than 10,000 species are among the most diverse of plant groups - a primary competitor for soil nitrogen.

The benefits observed were an increased plant growth and soil nitrogen content, higher soil organic matter content, and soil aggregation.

Soil Nitrogen Testing (N-Testing) is a technique that helps farmers optimize the amount of fertilizer applied to crops.

Increases in soil nitrogen have been found to increase plant dark respiration, stimulate specific rates of root respiration and increase total root biomass.

Considered one of the world's worst weeds, it reduces crop yields and causes forage crops to fail by removing up to 80% of the available soil nitrogen.

Plant nutrients are also released from soil organic matter by decomposition, and organic matter is particularly significant as the major form in which soil nitrogen is stored.

Palmer amaranth has a tendency to absorb excess soil nitrogen, and if grown in overly fertilized soils, it can contain excessive levels of nitrates, even for humans.

Resistant cultivars, liming the soil to change soil pH to 6-7, and reducing soil nitrogen levels also help control F. oxysporum f. sp.

Cato wrote De Agri Cultura ("On Farming") which recommended tillage, crop rotation and the use of legumes in the rotation to build soil nitrogen.

Pointing to the soil's crust, a mat splotched with bacterial growths that replenish soil nitrogen, Mr. Hedden said grazing left both grass and crust in tatters.

As well as bringing nitrogen into agroecosystems through biological nitrogen fixation, types of cover crops known as "catch crops" are used to retain and recycle soil nitrogen already present.

The Illinois Soil Nitrogen Test ("ISNT") is a method for measuring the amount of Nitrogen in soil that is available for use by plants as a nutrient.

Most soil nitrogen is locked up in organic matter - living and once-living materials - and the amounts available to plants changes as weather conditions influence the decomposition of organic matter by soil microbes.

The CDI surrounding the carcass will display an increase in soil carbon and nutrients, such as phosphorus, potassium, calcium, and magnesium; changes in pH; and a significant increase in soil nitrogen.

In the absence of tillage, and in soils with depleted organic matter, crops with large root systems may build up organic matter to the point that nearly all of the soil nitrogen and phosphorus is immobilized.

In temperate climates, evergreens can reinforce their own survival; evergreen leaf and needle litter has a higher carbon-nitrogen ratio than deciduous leaf litter, contributing to a higher soil acidity and lower soil nitrogen content.
