We tested four types of fertilizers on potatoes… and here are the yield results: T3: Manure + horn meal → 8.3 T/Ha T2: NPK fertilizer → 8.2 T/Ha T1: Bone meal → 6.29 T/Ha T4: Manure alone → 6 T/Ha The manure + horn meal combination is the most effective. It improves both growth and vegetative development, as well as tuber yield. Economically: ✔️ Up to 130,000 Ar in earnings with T3 ✔️ More profitable than chemical fertilizers

Main characteristics pH: 3.98 → highly acidic soil Mineral nitrogen: high Phosphorus: high Potassium: moderate The soil has already good nutrient potential, but high acidity reduces plant access to nutrients.
