Open Area
The increase in crop yield and quality has been studied in numerous field trials.
Potatoes
Yield increased from 900 grams per plant to 1,200 grams. The average potato size also increased. Large and medium potatoes prevail over small potatoes. In the trial, a yield increase of up to 38 percent of marketable potatoes of 30-60 mm was detected in the “Irga” potato variety. A 41 percent increase in efficiency was also found in the fraction over 60 mm.
Onion
Fertilization was carried out in accordance with usual good practice. Up to 17 percent higher efficiency has been measured. The quality of crops also increased. The percentage of marketable crop in the total harvest also increased significantly.
Sugar Beet
It shows an increase in yield of up to 21 percent compared to sugar yield.
Corn
Fertilization was carried out as usual in accordance with good practice. Up to 14.7 percent higher grain yield was measured compared to the control.
Strawberry
Increased shoot and root development in strawberry cultures. Adding it to strawberry cultures immediately after growing in greenhouses resulted in vigorous growth of shoots and roots. Additionally, the dry weight of the plants increased, proving increased nutrient uptake.
Basil
It has been shown that humic acid application is effective on growth and yield parameters. Humic acid application with H4 concentration (15 g/l for 0.5 m²) showed the best increase in growth and yield, but the largest plant height was observed in H2 (5 g/l for 0.5 m²).
Wheat
Thanks to the positive effect of the application, a 24 percent increase in the water retention capacity of the soil was achieved.
