soil ecosystem

A. castellanii can be found at high densities in various soil ecosystems.

It focused on maximizing the crop yield while maintaining a good soil ecosystem.

Scottnema is responsible for about 10 percent of the carbon processed in the Dry Valleys soil ecosystem.

The decaying mulch of good old manure and compost, full with a myriad bacteria, is required for a healthy soil ecosystem.

In traditional agricultural systems, tilling disturbs the soil ecosystem, affecting biotic and abiotic factors.

The whole of the planet's soil ecosystems is called the pedosphere where a large biomass of the Earth's biodiversity organizes into trophic levels.

When not properly recycled it can leach into the soil, harming microorganisms and disrupting the soil ecosystem.

Since EPNs are applied in agricultural systems at a rate of 1,000,000 individuals per acre, the potential for unintended consequences on the soil ecosystem appears large.

Aside from EPNs, the soil ecosystem includes predatory, bacteriovorous, fungivorous and plant parasitic nematode species.

Besides the grazing effect, another barrier to top down control in soil ecosystems is widespread omnivory, which by increasing the number of trophic interactions, dampens effects from the top.

An increase in primary productivity will result in a larger influx of leaf litter into the soil ecosystem, which will provide more resources for bacterial and fungal populations to grow.

The Family Geoplanidae, common name Land planarians (Platyhelminthes, Tricladida, Geoplanidae) is an understudied but important group of flatworms that belong to the soil ecosystem.

As part of the soil ecosystem land planarians feed mainly on other invertebrates such as earthworms, slugs and snails, termites, isopods, and other land planarians.

When arable land replaced pasture over much of Britain between the 1950s and 1980s, there was little in the soil ecosystem to hold nitrate back (only rarely is it all used by the crops).

Tree roots, fungi, bacteria, worms, ants, beetles, centipedes, spiders, mammals, birds, reptiles, amphibians and other less familiar creatures all work to create the trophic web of life in soil ecosystems.

Population level diversity is what provides ecosystem services, such as the keystone role that salamanders play in the soil ecosystems, including the nutrient cycling that supports wetland and forested ecosystems.

Learning objectives include physical properties of soil and soil formation, soil ecosystems, chemical properties of soil, soil conservation and land use management, and soil surveying, among others.

Concerns about effects of non-native earthworms on Park soil ecosystems have not yet led to the banning of worm bait, but anglers are urged to dispose of unused worms in garbage containers.

A review of the effects of Bt crops on soil ecosystems found that in general they "appear to have no consistent, significant, and long-term effects on the microbiota and their activities in soil".

Dry Valley soil ecosystems are characterized by large variations in temperature and light regimes, steep chemical gradients and a high incidence of solar radiation with an elevated ultraviolet B (UVB) light component.

The scientific themes particular to Micro are the rich diversity of life contained in soil ecosystems, which is remarkably well-adapted to its environment, and the physics of being small, first explored by Leonardo Da Vinci.

Conventional farming practices that rely on tillage have removed carbon from the soil ecosystem by removing crop residues such as left over corn stalks, and through the addition of chemical fertilizers which have the above mentioned effects on soil microbes.

Disinfection methods used prior to surface disposal of municipal sewage cannot be used with septic tanks because disinfection would prevent wastewater treatment by killing the septic tank and soil ecosystems catabolizing the putrescible contents of the wastewater.

Realizing his mistake, Vin Drake fakes an emergency and rushes the seven graduates to a Tensor generator - an incredible technology developed by Nanigen to shrink humans or artifacts with strong magnetic fields, so that they can then investigate soil ecosystems.
