Soil in a sentence

He listed the key steps to soil health: Limit soil disturbance; keep the soil covered; have live roots growing throughout the year; and use crop diversity to increase soil diversity.

AMF was also significantly correlated with soil biological fertility variables such as soil fungi and soil bacteria, including soil disease.

Soil bulk density is equal to the dry mass of the soil divided by the volume of the soil; i.e., it includes air space and organic materials of the soil volume.

Soil organic matter The use of different species in rotation allows for increased soil organic matter (SOM), greater soil structure, and improvement of the chemical and biological soil environment for crops.

So, where "active" soil organic matter is a key to productive soil, soil with low microbial activity provides significantly fewer nutrients to plants; this is true even though the quantity of biomass left in the soil may be the same.

When the organic component of a soil is substantial, the soil is called organic soil rather than mineral soil.

Encouraging Soil Samples: Soil samples from a 2020 soil sampling program returned values ranging from 5 parts per billion (ppb) gold to 32 ppb.

Members of the Brzostek Lab at West Virginia University marvel at the soil pit they dug to measure how miscanthus roots and soil microbes contribute to forming long-lived deep soil carbon.

Weeds help to pull nutrients from the soil and bring it to the surface, so they are good for the soil, and, by identifying which weeds are growing where, you can use them to guide you about your soil: is it too compact, does it lack certain nutrients?

Charles Wortmann, Extension soil and nutrient management specialist; Bijesh Maharjan, Extension soil and nutrient management specialist; and Laila Puntel, soil fertility and precision ag specialist, contributed to this report.

The greening of that patch over the past six months shows the progress of sand-to-soil practices, such as land reclamation, bringing soil from elsewhere to the area, or literally breaking sand down into soil using chemical compounds.

Biology in the soil thrives on a consistent temperature that doesn’t exceed 100 degrees F. Soil not covered by armor can reach temperatures of 125 degrees or more, driving biology deeper in the soil or into dormancy.

Using IRT to determine whether to irrigate dry beans can be simpler than using soil moisture sensors, because soil probes need to be installed just right and calibrated to the specific soil type in order to work correctly, according to Qiao.

She was elected to serve as the 2017 Chair of Soil Biology and Biochemistry Division of the Soil Science Society of America and is an Adjunct Faculty member with the Department of Crop and Soil Science at Oregon State University.

Simply broadcasting seed and allowing it to work into the soil naturally through frost-heaving might be effective, but having soil preparation done first to improve seed-soil contact is important for successful dormant-seeding.

By applying the three principles of minimum soil disturbance, legume-based cropping and the use of organic mulch, farmers can improve infiltration, reduce evaporation and soil erosion, and build up organic soil content.

Cultivation decreases soil nitrogen by exposing soil organic matter to decomposition by microorganisms, and soils under no-tillage maintain more soil nitrogen than tilled soils.

Plants derive a large proportion of their anion nutrients from decomposing organic matter, which typically holds about 95 percent of the soil nitrogen, 5 to 60 percent of the soil phosphorus and about 80 percent of the soil sulfur.

Soil analysis revealed about 1,900 times higher concentration of americium inside sandy soil particles than in the water present in the soil pores; an even higher ratio was measured in loam soils.

Soil analysis revealed about 4,000 times higher concentration of curium at the sandy soil particles than in water present in the soil pores.
