1. Right from the first application of Nongda fertilizer, the results were remarkable—Mr. Hao XX was overjoyed. With an investment equivalent to the usual cost, yields increased by 500 jin per mu; at an average price of 6 mao per jin, this translates to an additional income of 300 yuan per mu.
2. Mr. Hao XX stated that next year, all 1,000 mu of his potato fields will be fertilized with Nongda fertilizer, and he has recommended that other farmers also use Nongda fertilizer, as it both improves soil health and boosts yields.
