A qualitatively treated field makes it possible to increase the yield of agricultural crops, get rid of weeds, and prevent soil erosion.
To determine the correct method of tillage, you need to consider:
Processing can be autumn (in autumn) and pre-planting (in spring).
Before plowing, it is peeling of soil.At the same time, the vegetation remaining after harvesting is crushed and submerged in the ground along with weeds that have become stronger after harvesting. Soon, some of the remaining grains germinate, using a green carpet on a cultivated field. What is the method of their destruction? Provocation. After all, seedlings, provoked by peeling, disappear after plowing. And not ascended grains, falling deep into the earth, lose their germination in 4-5 years (some for 2 years).
Usually the field is discled once, but if the predecessor was perennial grass, then you need to go twice in different directions.
Light soils are plowed in early September. Heavy - in early August. Fields with a slope of more than 7 degrees are treated across the slope so that the soil is not washed away by water flows.
In the spring field fertilize and loosen:harrowed, cultivated and plowed. Organics contribute after thawing the earth at 10 cm and treated area with discs. Mineral fertilizers - before plowing or loosening. At the same time the processed field gets rid of a superficial crust, reducing evaporation of moisture. Another part of the weed dies. Fertilizers get to where the plant root system will later develop.
To combat weeds having a longrhizome (thistle pink, convolvulus), use the method of depletion. Plant roots are systematically pruned. On the plot, it can be done manually. It is more difficult to apply this method on the field, especially during early autumn plowing.
Not so long ago were able to overcome the creeping couch,covered with hard stalks cultivated field. What is the name of this radical way? Strangulation Pyrei deserves it, because its shoots grow with terrible force. It turns out that at a depth of 20 cm the germination of rhizomes almost stops. If during active growth the field is discarded and plowed with the use of skimmers, the number of this annoying weed will decrease significantly.
These methods are quite effective.But if in the spring for any reason you had a poorly cultivated field, then all the weeds will remain. You will have to fight them with the help of herbicides, which are divided into:
Selective effect only on weeds. Cultivated plants are not damaged. Can be applied to the treated field after the germination of the main crop.
Non-selective effect on all plants that are on, except for genetically modified. Treated field, which grows only weeds, after harvest or in early spring.
The following herbicides of continuous action are distinguished:
Contact affects only that part of the plantwhere got the herbicide. They quickly destroy annual weeds. In systemic active substance gradually moves to the points of growth, causing them to die. Well removes wheatgrass, thistle.
Weed control is expensive and troublesome. But the result is worth it.
