Root trainer pots. Many pot designs train the roots. One example is a truncated plastic cone in which a seedling is planted. There is a drainage hole at the bottom and the main tap root tends to grow towards this. What this achieves is to encourage the roots to grow a denser system of root hairs.
A conspicuous sign of water problems is the wilting of leaves. [23] Giving too much water can kill cannabis plants if the growing medium gets over-saturated. This is mainly due to oxygen not being able to enter the root system. [24] Anaerobic bacteria start to accumulate due to waterlogged, stale conditions.
Attached weights forced the blade back into the ground after the root was passed, allowing as much of the ground to be furrowed as possible. Although a little unorthodox, the plough in action appearing "like a ship in a storm", [12] it proved remarkably effective, and was dubbed the "stump-jump" plough (also spelt without the hyphen).

Zone tillage is a form of modified deep tillage in which only narrow strips are tilled, leaving soil in between the rows untilled. This type of tillage agitates the soil to help reduce soil compaction problems and to improve internal soil drainage. [12] It is designed to only disrupt the soil in a narrow strip directly below the crop row.
Saturday marks marijuana culture’s high holiday, 4/20, when college students gather — at 4:20 p.m. — in clouds of smoke on campus quads and pot shops in legal-weed states thank their ...
They can be eaten raw, but are usually baked. Cooked, the rhizomes become translucent, mucilaginous, and sweet. Starch is produced by grinding or pounding the roots and soaking them in water, separating the starch granules from fibers in the roots. The starch granules of C. indica are also translucent and the largest known from any plant.
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.
A problem with no-till farming is that the soil warms and dries more slowly in spring, which may delay planting. Harvest can thus occur later than in a conventionally tilled field. The slower warming is due to crop residue being a lighter color than the soil exposed in conventional tillage, which absorbs less solar energy.
