In some previous studies on agricultural soils, long-term N fertilizer application seemed to stimulate the growth of AOB [ 13, 27].
The foam stabilized the soil long enough for it to be excavated, then the miners lined the exposed walls with watertight concrete rings.
Translation: to combat the plague of resistant Italian ryegrass, Mississippi's cotton farmers must hit their fields with a "residual" herbicide in the fall – meaning one that hangs around in soil long enough to kill ryegrass for a while, and then come back with yet another herbicide in the spring, to make sure the job has been done.

Many of these drugs, including fluoroquinolones, sulphonamides, and tetracyclines, are relatively stable molecules that can persist in water, sediment, or soil long after excretion from humans or animals after therapy, thus providing possible selective advantages to resistant bacteria (23 ).
While it is known that plants uptake amino acids from soil, long term studies that link amino acid uptake to measures of plant performance and potential reproductive effort are not typically performed.
The influence of leaching and microorganisms on simazine attenuation in an agricultural soil long-term treated with this herbicide was studied.
Increasing DMR increased the time that water was continuously available to plants in the upper 15 to 30 cm of the soil (longest wet period, LWP).
