President discusses experiment with potassium waste as fertilizer on Dzerzhinsky test field

"You have chosen a very right place."

President on the experiment conducted at the Dzerzhinsky test field.

The idea is as follows:

- Introduce potassium plant waste into the soil and see what yield can be achieved on this not-so-good field — in this case, corn.

- The field was divided into six plots. Each received different fertilizer combinations, and the yields were compared.

- The best result was achieved on the plot where compost with sludge was applied.

- The President proposes using this approach on low-fertility lands, but first calls for a comprehensive study and a scientific approach.

- The experiment will continue.

Main question: "What to do with these sludges?"
