(54) METHOD FOR TREATING SALTED SOILS

I

The invention relates to agriculture, namely to agriculture, in particular to methods of dealing with saline soils on land arable land.

There is a method of dealing with saline soils, which includes a two-Russian treatment without mixing the Rus and simultaneously adding gypsum or other ameliorants directly to the solonetz horizon when it is loosened. Ll.

The disadvantage of this method of amelioration of solonets is the absence of active loosening of the solonetz horizon, which does not ensure a high degree of contact of the ameliorant with the entire soil mass.

There is also known a method of two-layer amelioration, which includes the introduction of granular capillary-containing ameliorant into the upper loosened sodic layer and under it liquid acid-containing products with subsequent or simultaneous deep soilless soil loosening, 21,

However, introduced chemical ameliorates without actively mixing them with the soil do not give a significant ameliorative effect.

The aim of the invention is to accelerate the ameliorative process and improve the effective fertility of old arable sod soils.

The goal is achieved by the fact that the upper Russian is loose to agronomically valuable

10 of the structure, simultaneously with the active loosening, ameliorate is introduced, mixing it with the soil and displacing the soil of the upper tusk toward the treated part of the floor by the width of the passage of the unit,

15, while the opening lower rus is actively loosening, involving soil calcium salts of the sunflower horizon with mixing them with a solonetz horizon.

With a shortage of soil salts, simultaneously with the active loosening of the soil of the lower Rus, drip-containing ameliorant is introduced.

FIG. 1 shows the profile of the old tillage soponets; in fig. 2 - profile of its upper and lower Rus after active treatment, while A - - plowed horizon, B. - remaining solontsy horizon after plowing of the virgin lands; В “- subsurface horizon.

The method is carried out with the help of a ripper plow having two types of working bodies: passive and active. The passive belong to the hull working bodies from the plow PN-4-35} to the active - cutters (vertical and horizontal). Body working bodies are used for cutting soil layers to the corresponding depth of the upper and lower Rus (Fig. 2).

To prevent mixing of the Rus on the plow there is a shield-dump.

A hopper is mounted on the ripper plow, from which improver is fed to be mixed with the soil at the moment of its crushing by mills.

The arable horizon (A.dudu) with a capacity of 23-24 cm is subjected to active crumbling to an agronomically valuable structure with the simultaneous introduction of a me- dorete into it and mixing it with the soil mass and moving it to the side of the treated floor to the width of the passage of the unit. In such a case, the open lower rus, consisting of a part of the horizon AjiQ, B and B ft, also crumbles, mixes the soil with soil Calpevium salts, or, if necessary, ameliorated ameliorates, and leave them in place. During the subsequent passage of the aggregate, the upper rus will be mixed into the promeliorized lower, and so on.

The proposed method of processing sodic soils provides a high degree of contact with ameliorant with its soil mass in each ore-produced river, which leads to an acceleration of the ameliorative process, a rapid growth of effective fertility of old arable sod soils, and an increase in its economic efficiency.

The use of this method in the national economy will significantly reduce the reclamation period by accelerating the process of displacing movable sodium from the soil absorbing complex of the reclaimed arable layer as a result of good contact of the calcium ameliorant with the soil while actively mixing them throughout

the treated volume of the reservoir. Thus, it is possible to quickly and significantly increase the effective fertility of old arable plantations, reduce the payback period of capital expenditures for their amelioration.

Claims (2)

1. The method of processing sodic soils, including two-lined loosening without mixing the soil of the Rus and the introduction of an ameliorant, characterized in that, in order to speed up the ameliorative process and increase the effective fertility of the old arable saline soils, the upper layer is loosened to an agronomically valuable structure, simultaneously with the active loosening the ameliorant is added, mix it with the soil and shift the soil mass of the upper rusa, in the direction of the processed part, the floor is the width of the passage of the unit, while the opening lower rus is actively loosening, involving soil calcium salts of the sunflower horizon with alternating stallation them solonetz horizon. 2. The method according to claim 1, of which is due to the fact that with a lack of calcium soil salts at the same time with active loosening of the soil of the lower Rus, calcium-containing ameliorant is introduced.
