Yes. Assuming that you are not an agricultural sciencegraduate, I am answering this question for you. Soil sample under test is classified as saline-sodic soil. It requires reclamation before it can be used for crop cultivation. Add adequate irrigation water and deep plough the field. Dig 3 feet deep and three feet wide trench all over the border of the field to permit free drainage of water used for irrigation. Apply liberal quantities of greenleaves such as neem,pongamia,gliricidia,subabul,indigo etc and tample the same in to the field and allow to decompose in presence of adequate moisture for a period of 20 days. Repeat to drain away the water with dissolved salts and to enrich organic matter content of the soil at least three times and finally test the soil for pH and EC. Both should come down to below 8.00 and below 4 mS/dcm respectively. Once you ensure this, you can plan to grow sorghum,bajra,fingermillet, pearlmillet, the crops that are capable of providing good yields.

Some soils (actually we should address as substrate/waste etc for it) could be found in large quantities. For example mine tailings/wastes are very saline (high EC values) and sodic (high pH values), you cannot irrigate such large quantities. But compost usage is a good option for soil amelioration. Is there any other solution to manage such soils or wastes?

Salt exhaustive crops such as Acacia species can be successfully grown planting them during rainy season if assured irrigation facilities are not avaiable in a given region. It is also essential to cover the land with leaf litter to prevent direct exposure of the land to sunlight i.e., mulching as it is called. Not even a drop of rain water should be allowed to go as surface runoff and instead it should travel downward to facilitate dissolution of salts present in excess in such soils. Land should never be designated as waste land since it is unethical to do so since it is manmade due to improper management in any part of the world.

Professor Reddy has very clearly solved the problem. With usual methods of treatment like washing etc. plantation of some aromatic plants with ago-forestry, selecting trees resistant to these soils may help reclaim these soils quickly. Meanwhile, this practice may accrue more profit than the traditional cropping.

I think your soil or substrate may be a waste/tailings of mining operation. You did not mention about it. Could you explain your material? If it is large quantities, it may be establish here salt or alkaline condition tolerant plant/tree species for reclamation.
