Abstract
A method to change and optimise the level of acidity and the mineral composition of a soil that has undergone salinization or changes in the optimal level of acidity as a result of natural phenomena or anthropic activities, said method comprising the treatment of the soil with an aqueous suspension of hydrophilic sulphur having peculiar features of acidity and granulometry of the suspended phase. The above treatment allows at the same time a rapid fertilisation of the soil and is a faster and more effective way of disposing of excess sulphur resulting from the processes of purification of fossil fuels.
Claims (12)
1. Method for modifying the chemical composition of a soil, comprising the treatment of said soil with a suitable amount of an aqueous suspension of hydrophilic sulphur with a concentration in S comprised between 0.5 and 300 g/L, preferably between 5 and 200 g/L, more preferably between 15 and 150 g/L, pH comprised between 0 and 4, more preferably between 0.5 and 2, said sulphur having an average granulometry of between 2 and 100 Î1⁄4ιη (micron), measured with the "light scattering" method.
2. Method according to claim 1 , wherein said treatment comprises the distribution on the soil's surface of a quantity of said hydrophilic sulphur aqueous suspension such that the average quantity of S distributed on the soil is between 10 and 500, preferably between 50 and 300, g/m2 of soil.
3. Method according to any of the claims 1 or 2, wherein said aqueous sulphur suspension comprises from 0.05 to 10.0 %, preferably from 0.1 to 5 %, by weight of polythionic acids, with respect to the total weight of the suspension.
4. Method according to any of the preceding claims, wherein said soil comprises an overall ion concentration such as to result in an electrical conductivity of the medium greater than 1.0 dS m-1, preferably greater than 2.0 dS m-1.
5. Method according to any of the previous claims, wherein said soil has a pH higher than 6.5, preferably higher than 7.0.
6. Method according to any of the preceding claims, wherein said hydrophilic sulphur suspension also comprises at least one suspension agent.
7. Aqueous suspension of hydrophilic sulphur, having the following features: concentration in S between 15 and 300 g/L, preferably between 15 and 150 g/L, pH between 0 and 4, preferably between 0.2 and 2.0, said sulphur having an average particle size between 2 and 100 Î1⁄4ιη (microns), measured with the "light scattering" method.
8. Aqueous suspension of hydrophilic sulphur according to claim 7, having a PZC comprised between 1 and 3.
9. Aqueous suspension of hydrophilic sulphur according to claims 7 or 8, which is obtained by a process which includes making an aqueous solution of S02 react with H2S, at a temperature equal to or lower than 100°C, preferably between 5°C and 40°C.
10. Aqueous suspension of hydrophilic sulphur according to any of the preceding claims from 7 to 9, for use as soil improver.
11. Aqueous suspension of hydrophilic sulphur according to any of the preceding claims from 7 to 10, having a pH comprised between 0.5 and 1.95
12. Method according to any of the previous claims from 1 to 6, in which the treatment of the soil is carried out with an aqueous suspension of hydrophilic sulphur according to any of the claims from 7 to 9.
