Humic acids from vermicompost positively influence the nutrient uptake in mangosteen seedlings
The application of growth promoting substances, such as humic acids, during the formation of fruit seedlings can benefit growth and increase the plant nutrient uptake and translocation. This study aimed to evaluate the effect of the application of humic acid doses (0 mg L-1, 2 mg L-1, 20 mg L-1, 40...
