Tillage erosion is the soil movement and erosion by tilling a given plot of land. [3] A similar practice is contour bunding where stones are placed around the contours of slopes. Contour plowing has been proven to reduce fertilizer loss, power, time consumption, and wear on machines, as well as to increase crop yields and reduce soil erosion.
Agricultural wastewater treatment is a farm management agenda for controlling pollution from confined animal operations and from surface runoff that may be contaminated by chemicals in fertilizer, pesticides, animal slurry, crop residues or irrigation water. Agricultural wastewater treatment is required for continuous confined animal operations ...
Breaking down organic substances, degradation, involves interactions among microorganisms in the soil. Sorption affects bioaccumulation of pesticides which are dependent on organic matter in the soil. Weak organic acids have been shown to be weakly sorbed by soil, because of pH and mostly acidic structure.
At least 40 million acres in the United States, an area larger than the state of Georgia, are covered by turf grass, the standard lawn plant. Leaf blowers, lawn mowers and fertilizer: How lawns ...
Soil loses nutrients, like nitrogen and fertilizer, and its ability to store water. [17] [note 2] Decreases the water infiltration rate of soil. (Results in more runoff and erosion [17] [19] as the soil absorbs water more slowly than before) [note 3] Tilling the soil results in dislodging the cohesiveness of the soil particles, thereby inducing ...
Common attributes of soil degradation can be salting, waterlogging, compaction, pesticide contamination, a decline in soil structure quality, loss of fertility, changes in soil acidity, alkalinity, salinity, and erosion. Soil erosion is the wearing away of topsoil by water, wind, or farming activities. [54]
Lawn burweed (Soliva sessilis) germinates in the fall as early as September and flourishes throughout the winter. In late winter to early spring, tiny white flowers that produce the spiny seeds ...
where water tables are shallow, the irrigation applications are reduced. As a result, the soil is no longer leached and soil salinity problems develop; stagnant water tables at the soil surface are known to increase the incidence of water-borne diseases like malaria, filariasis, yellow fever, dengue, and schistosomiasis (Bilharzia) in many ...
