Fertilizers have important elements which promote plant growth and development. Currently, chemical fertilizers are preferred in agriculture because of their effectiveness, abundance, and high nutrients content, as compared to natural or organic fertilizers. However, the increased use of chemical fertilizers has been implicated in human health and environmental quality. Thus, less harmful fertilizers are needed in modern agriculture as an alternative of chemical fertilizers. Application of humic fractions mixture as a fertilizer could be useful in promoting plant growth and selected soil chemical properties. Furthermore, there is dearth of information on the effects of this fertilizer on crops growth and development. Thus, three studies wer...
