The Effect of Mycorrhiza, Phosphorus and Humic Acids on Increasing the Content and Availability of N, P, and K During Vegetative Growth and Wheat Harvest

Abstract

Mycorrhiza (M1) led to a significant increase in the availability of nutrients (K, P, N) in the soil during the growth stage. Moreover, treatment with phosphorus (P2) led to a significant increase in the availability of macronutrients (K, P, N) in the soil. The addition of humic acids also significantly increased the availability of K, P, and N in the soil. The joint interaction between fungal roots and humic acids was to provide the greatest amount of macronutrients in the soil during the vegetative development and harvest stages. The mutual interaction between mycorrhizae and phosphorus in the M1P2 treatment resulted in the greatest nutritional availability. The macronutrient levels in the soil during the vegetative development and harvest phases are as follows: 46.19 mg.kg-1 soil for the first nutrient, 35.41 mg.kg-1 soil for the second nutrient, 222.91 mg.kg-1 soil for the third nutrient, 39.28 mg.kg-1 soil for the fourth nutrient, and 26.00 mg.kg-1 soil for the fifth nutrient. The combined effect of the research components resulted in a substantial rise in the presence of macronutrients (potassium, phosphorus, nitrogen) in the soil during the stages of plant growth and harvest. The concentrations of these nutrients were measured at 53.81, 39.07, 253.82, 43.80, 30.55, and 210.62 mg kg-1 soil for potassium, phosphorus, nitrogen, respectively.
