Once the weeds appear, they are easily eliminated by various methods that minimize further ...

make soil dry quicker after rain or irrigation, so that the soil can be worked sooner; Consequently, these translate into stronger, larger plants with more extensive root system; earlier seed emergence and crop maturity; more efficient water utilization; easier weed removal; more response to fertilizers and to new crop varieties
Brick weed is a curing and packaging method of cannabis cultivation that consists in drying the bud for a short period, if at all, and pressing it with a hydraulic press, compacting the whole plant (bud, stems and seeds) into a brick, hence the name brick weed.

Herbicide adsorption to soil colloids or organic matter often reduces the amount available for weed absorption. Positioning of the herbicide in the correct layer of soil is very important, which can be achieved mechanically and by rainfall. Herbicides on the soil surface are subjected to several processes that reduce their availability.
