College of Agriculture, Al-Qasim Green University discussed a master dissertation on the effect of adding agricultural sulfur and spraying with humic acids on the readiness of some nutrients in the soil and the growth and yield of potatoes by the postgraduate student, Mr. Rami Munther Abd Al-Kadhim.

The dissertation aimed at identifying the effect of adding agricultural sulfur to the soil on the readiness of nutrients and spraying with humic acids on the growth and yield of potatoes, as well as finding the best combination to achieve the highest yield of potatoes and some other soil characteristics.

The dissertation confirmed that the treatment of adding agricultural sulfur at level S2 (1500 kg h-1) achieved the highest growth indicators for the potato crop and nutrients in the soil and tubers compared to the comparison treatment S0. Also, spraying with humic acids at level A2 (50 g fertilizer / 100 liters of water) gave the highest growth indicators for the potato crop and the highest yield and number of tubers, and the dual interaction treatment S1A2 also achieved an increase in the percentage of dry matter and some other characteristics.

The dissertation recommended adding agricultural sulfur with humic acids (soil addition) as a soil conditioner, as well as its nutritional role and conducting other experiments on field crops such as wheat and barley, in addition to using spraying with humic acids at a concentration of 50 g of fertilizer/100 liters of water, and emphasizing the addition of agricultural sulfur before planting for another period.
