INVENTION
Russian Federation Patent RU2067804
METHOD FOR TREATMENT OF SOIL
Name of the inventor: Major RA .; Suvorov VI .; Solovyov NL .; Akimova OV
The name of the patentee: Major Rudolf Arsen'evich
Address for correspondence:
Starting date of the patent: 1994.07.12
The invention relates to the field of agriculture. The soil treated by mulching peat crumbs, pre-mixed with calcium compounds. According to the invention peat is further added ammonium lignosulfonate in an amount of 0.02 - 0.5% by weight. based on dry substance, followed by stirring. As the calcium compound used is calcium carbonate, which is made in an amount calculated by the formula given in the description.
DESCRIPTION OF THE INVENTION
The invention relates to the field of plant and can be used in agriculture for growing vegetable and fruit crops in the open field, but also in fruit growing.
There is a method of mulching the soil with peat litter humidity of 50 - 60% of the layer thickness of 2 to 10 cm drills or mulchers. For mulching using peat fen and transition type with medium or high degree of decomposition. However, this peat is acidic medium exchange acidity is in the range of pH 3.5 5.5 (Major R. Bazin ET Popov MV Use of peat and peat deposits in the national economy. M. Nedra, 1992, p. 239).
The disadvantage of this method is that when peat mulch plowing the soil after cleaning mulchiruemoy culture in interrow processing tree trunks or processing plants, the soil will be observed acidification of the solution, which would adversely affect the subsequent crops.
There is a method of processing crop seeds (copyright certificate USSR N783333, cells S09K 17/00;. A01S 7/00, 1980), including mulch peat crumbs, pre-mixed with calcium carbide in a weight ratio of 1 5 parts by weight 100 parts by weight peat and humidified to a moisture content of 70 - 80% of field capacity, which accelerates the growing of plant seeds.
The disadvantages of this method are unsolved problems associated with wind erosion used for peat mulch.
The present invention is to provide a method for peat soil mulching, which would take into account both the change in acidity peat soil plowing with decreasing exposure to wind erosion peat.
The stated object is achieved in that the tillage method by peat mulch crumb premixed with the calcium compound in Peat ammonium lignosulfonate was further added in an amount of 0.02 0.5% by weight. based on dry substance followed by stirring, and calcium compounds are used as calcium carbonate, which is introduced in an amount of: 
Where 
introducing the dose of calcium carbonate per 1 ton of peat kg;
Collar nut hydrolytic acidity of peat, mEq / 100 g; 
RH peat
m sl weight ammonium lignosulfonate in terms of absolutely dry matter, kg / t.
Advantageously, the moisture content of the peat chips used for mulching, was 50 to 60%
It is advisable to mulch the soil with peat thickness of 2 to 10 cm.
Tillage both calcium carbonate and ammonium lignosulfonate allows to achieve positive results associated with mulch, fertilizer, deoxidation and mulch and protection from wind erosion. This combination of positive results achieved by empirically selected amounts of reactants introduced into the soil. Changing their relationship does not allow you to perform a task in the invention.
Best Mode for carrying out the method.
Example.
To prepare the mulch peat moss with humidity 54% was added calcium carbonate and ammonium lignosulfonate.
Introducing the dose of calcium carbonate is calculated according to the formula.
Producing intimate mixing and soil mulching peat layer of varying thickness, from 2 to 10 cm.
Subsequently stirred and peat and the soil samples were taken to determine the acidity of the mixture. The controls were the results of experiments with pure peat.
The data obtained from comparative tests proposed and known methods of mulching the soil are given in the table.
Investigation of the protective properties of ammonium lignosulfonate was conducted in an environmental chamber under the influence of air flow rate of 10 m / s for pure samples of peat and peat with additives; at a humidity of 30% ash particles from the surface of the sample was pure peat 10% from the surface with the addition of peat ash particles ammonium lignosulfonate was not observed.
Peat treated ammonium lignosulfonate, more effectively resists wind erosion. And the presence of calcium carbonate in the peat used for mulching, has a positive effect on soil fertility.
The invention is now passed laboratory tests and can be used for growing crops.
CLAIM
1. A method of treating soil by the peat mulch crumb premixed with the calcium compound, characterized in that the peat is further added ammonium lignosulfonate in an amount of 0.02 0.5 parts by weight based on dry substance followed by stirring, and calcium compounds as calcium carbonate is used in an amount determined by the relation
Where introducing the dose of calcium carbonate per 1 ton of peat kg;
H g hydrolytic acidity of peat, mEq / 100 g; RH peat
m sl weight ammonium lignosulfonate in terms of absolutely dry matter, kg / t.
2. The method of claim. 1, characterized in that the moisture content of the peat chips 60 should be 50
3. The method of claim. 1, characterized in that the peat soil mulching chips stacked layer thickness of 2 to 10 cm.
