Effective soil pollution control involves various methods and practices. These include understanding the baseline of soil environment quality through sensitization and surveys, controlling mining and industrial pollutants with strict supervision, and promoting reforestation and afforestation for pollutant absorption and improved soil health. Minimizing chemical fertilizer use, ensuring proper waste disposal, and encouraging organic manure usage are vital steps. Recycling and reusing waste materials, incorporating proper land use planning, adopting organic farming and agricultural land management, and fostering education and awareness activities are integral to preventing soil contamination. By implementing these measures, we can successfully control soil pollution, ensuring environmental protection, human health preservation, and overall sustainability.
As C.A. (Kees) Kan said, it is not clear what control you mentioned.
In any case, if you need to monitor soil pollution, you should first start with a statistical sampling plan to get an idea of the distribution of the pollution.
