Some weed seeds (such as those of Bermuda grass and species of bindweed) may persist under the barrier and within the soil seed bank. [3] Termites are attracted to the area. [11] While they are a natural part of the ecosystem that transforms the weed barrier into rich soil, they can pose a hazard to nearby wood-framed structures.
Landscape fabric (a.k.a., weed barrier) is a textile material used to control weeds by inhibiting their exposure to sunlight. The fabric is normally placed around desirable plants, covering areas where other growth is unwanted. The fabric itself can be made from synthetic or organic materials, sometimes from recycled sources.
Companion planting of carrots and onions. The onion smell puts off carrot root fly, while the smell of carrots puts off onion fly. [1]Companion planting in gardening and agriculture is the planting of different crops in proximity for any of a number of different reasons, including weed suppression, pest control, pollination, providing habitat for beneficial insects, maximizing use of space ...
This mulch can prevent soil erosion, reduce weeding, conserve soil moisture, and increase temperature of the soil. [28] Ultimately this can reduce the amount of work a farmer may have to do, and the amount of herbicides applied during the growing period. The black and clear mulches capture sunlight and warm the soil increasing the growth rate.
Peas were shown to reduce the density of Colorado potato beetles. [13] Pumpkin: Cucurbita pepo: Corn, (in trad.

Concrete used for canal lining is typically non-reinforced, as a way to reduce cost. A common method for constructing concrete lining is the use of slip forms, which are drawn down the length of the canal as the concrete is poured. [3] Hand laying of concrete or prefabricated sections are also used when only a short distance needs to be covered ...
The overall mass of concrete can be reduced by 35–50% depending on the design, [1] as a consequence of reduced slab mass, as well as lower requirements for vertical structure and foundations. Biaxial slabs commonly span up to 20 metres at a thickness of around 500 mm. [ citation needed ] The added strength also reduces the acoustic ...
