However, conservation tillage delays warming of the soil due to the reduction of dark earth exposure to the warmth of the spring sun, thus delaying the planting of the next year's spring crop of corn. [10] No-till – plows, disks, et cetera are not used. Aims for 100% ground cover.
Another possible benefit is that because of the higher water content, instead of leaving a field fallow it can make economic sense to plant another crop instead. [25] 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.
An example is the Three Sisters, the inter-planting of corn with pole beans and vining squash or pumpkins. In this system, the beans provide nitrogen; the corn provides support for the beans and a "screen" against squash vine borer; the vining squash provides a weed suppressive canopy and a discouragement for corn-hungry raccoons.

The stale seed bed technique of weed control was developed before herbicide use began. It reduces the soil's seed bank or quantity by allowing the weed seeds both opportunity and time to germinate, sprout, and appear before the intended crop is planted. Once the weeds appear, they are easily eliminated by various methods that minimize further ...
Aerial video of a sprayer (unfolding and driving) A sprayer is a device used to spray a liquid, where sprayers are commonly used for projection of water, weed killers, crop performance materials, pest maintenance chemicals, as well as manufacturing and production line ingredients.
It is based on in-depth understanding of chemical ecology, agrobiodiversity, plant-plant and insect-plant interactions, and involves intercropping a cereal crop with a repellent intercrop such as Desmodium uncinatum (silverleaf) [4] (push), with an attractive trap plant such as Napier grass (pull) planted as a border crop around this intercrop ...

Thlaspi arvense is a foetid, hairless annual plant, growing up to 60 cm (24 in) tall, [2] with upright branches. The stem leaves are arrow-shaped, narrow and toothed. It blooms between May and July, with racemes or spikes of small white flowers that have 4 sepals and 4 longer petals. [3]
