Qualitatively processed field - an effective way to control pests

Qualitatively processed field makes it possible to increase the yield of crops, get rid of weeds, prevent soil erosion.

Landslide and preplant field cultivation

To determine the correct method of soil cultivation, it is necessary to take into account:

• Composition and density of the soil;
• Terrain relief;
• Clogging of the site;
• Culture, which occupied the field in the previous year.

Processing can be autumn (in autumn) and pre-plant (spring).

Before plowing, plowing is carried out on the plowland. In this case, the vegetation remaining after harvesting is crushed and submerged into the ground together with the weeds that have grown stronger after harvesting . Soon, some of the remaining grains germinate, with a green carpet treated field. What is the name of the method of their destruction? Provocation. After all, the sprouts provoked by peeling will disappear after plowing. And not the ascending seeds, getting deep into the earth, lose their germination in 4-5 years (some for 2 years).

Usually the field is burned once, but if the predecessor was a 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 processed across the slope so that the soil does not wash off with water streams.

In spring, the field is fertilized and loosened: harrowed, cultivated and plowed. The organic is applied after thawing the earth by 10 cm and the area is treated with discs. Mineral fertilizers - before plowing or loosening. In this case, the treated field gets rid of the surface crust, reducing the evaporation of moisture. Another part of the weeds is dying. Fertilizers fall where the root system of plants will subsequently develop.

How to deal with perennial weeds

To combat weeds that have a long rhizome (pink sage , convolvulus), a method of exhaustion is used. Plant roots systematically pruned. On the plot you can do it manually. On the field, this method is more difficult to apply, especially in the early autumn plowing.

Not so long ago , a creeping field , covered with hard stems , was able to overcome the grass . What is the name of this radical method? Strangulation. The paddies deserve it, because his shoots grow with terrible force. It turns out that at a depth of 20 cm the germination of the rhizomes almost ceases. If during the active growth the field is disced and smelled with the use of skimmers, the number of this annoying weed will be greatly reduced.

Than weed fields from weeds

These methods are quite effective. But if in the spring for some reason you have a poorly processed field, then all the weeds will remain. Fight them with herbicides, which are divided into:

• Selective;
• Nonselective.

Selective only act on weeds. Cultivated plants are not damaged. Can be applied to the treated field after germination of the main culture.

Non-selective act on all plants that are affected, except genetically modified. Process a field on which only weeds grow, after harvesting or early spring.

There are the following herbicides of continuous action :

• Contact;
• System.

Contact affects only that part of the plant, where the herbicide hit. They quickly destroy annual weeds. In the systemic, the active substance gradually moves to the growth points, causing their death. Well removes couch grass, sow.

The fight against weeds is a costly and troublesome business. But the result is worth it.
