Weed control is a type of pest control, which attempts to stop or reduce growth of weeds, especially noxious weeds, with the aim of reducing their competition with desired flora and fauna including domesticated plants and livestock, and in natural settings preventing non native species competing with native species.
The first step to removing weeds from your lawn and garden is identification. Learn about 20 common types of weeds and how to treat them.
The rows formed slow surface water run-off during rainstorms to prevent soil erosion and allow the water time to infiltrate into the soil. Soil conservation is the prevention of loss of the topmost layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination
With soil solarization, the seed bed is covered with a clear plastic sheet which heats the soil to a temperature that kills pests, pathogens, and weeds. With occultation, black plastic or silage tarps are laid over the soil, creating a moist and warm environment in which weed seeds germinate, and then die due to lack of light.
The fabric itself can be made from synthetic or organic materials, sometimes from recycled sources. When placed under a thin layer of soil or mulch, landscape fabric is unfortunately ineffective at blocking weeds because they can grow above or through the fabric. Once weeds grow through the fabric, they become extremely difficult to remove ...
Weeds may also act as a "living mulch", providing ground cover that reduces moisture loss and prevents erosion. Weeds may also improve soil fertility; dandelions, for example, bring up nutrients like calcium and nitrogen from deep in the soil with their tap root, and clover hosts nitrogen-fixing bacteria in its roots, fertilizing the soil directly.
Cover crops manage soil erosion, soil fertility, soil quality, water, weeds, pests, diseases, biodiversity and wildlife in an agroecosystem—an ecological system managed and shaped by humans. Cover crops can increase microbial activity in the soil, which has a positive effect on nitrogen availability , nitrogen uptake in target crops , and ...
Tillage is able to control weeds because when the soil is overturned, the vegetative parts of the plants are damaged and the root systems are exposed causing desiccation. [8] Generally, the younger the weed is, the more readily it can be controlled with tillage. [6] To control mature perennial weeds, repeated tillage is necessary.
