Abstract

There are studies that demonstrate several benefits of humic substances in agriculture. Based on this, this mini review aimed to present the main effects of the use of humic substances on the soil and the plant. For this, bibliographical references were used with an approach to humic substances on a world scale. Overall, the review showed that the chemical, microbiological and physical properties of humic substances can ensure an increase in agricultural productivity as a result of the benefits it promotes for the physical and chemical structure of the soil, for root development and plant metabolism, generating benefits in increasing agricultural productivity.

Keywords

Plants, Humic, Agriculture, Microbiological structure

Introduction

The agriculture in Brazil has been presenting a constant social and economic growth, with employment and income generation, in addition to significant increment of the gross domestic product (GDP)of the country. However, one of the current difficulties is the generation of technologieswith renewable and sustainable sources,which respect the environment and ecosystem. Among those concerns, soil fertility management has been the main target of national researches being developed in the country. As those researches advanced, there were several management system transitions with the aim to attain crop yield records and also in an attempt to resolve certain soil science paradigmssuch as production versusconservation.The Brazilian agriculture became highly competitive against international competitors. The firsttechnological leap was the No-tillage System, with preservation of residues (straw) for organic matter provision, with benefits that have been proven. Since then, theorganic matterhas been themain targetin terms of soil benefitsassociated with productivity and sustainable agriculture.

 Sustainable Development: Reality Or Myth? Since the United Nations Environment Conference in Stockholm (1972), the concept of sustainable development has steadily made its way among individual scientists and international organizations. The apotheosis of this development was the adoption by the United Nations in 2015 of the 17 Sustainable Development Goals. However, many scientists and politicians were skeptical about the concept of sustainable development, since the results of implementing sustainable development in different countries were far from expected. Many decisions taken at the level of the UN and other international organizations turned out to be unfulfilled. In my opinion, as well as some other Russian scientists, the concept of sustainable development is an unrealistic project, it is a myth, although it is very positive and humane. Sustainable development goals can be achieved only by the most economically developed countries entering the era of post-industrialism. In...

 How to Treat Cancer Properly Cancer is one of the deadliest diseases in the world, chemotherapy is effective under some conditions, but has too heavy side effects, and it is not effective to a considerable proportion of cases while the side effects are often life-threatening, drugs (not unhealthy addictive drugs mentioned in reference four, the drug in reference four only mean those makes people addictive but does no good to health, destroying health quickly) are not always available to improve the condition. However, sport is a potential treatment that is effective to cancer before the cancer is disseminated, this gets little attention but is true both in theory and practice. The physical activities that have moderate intensity and duration should have devastating effects on cancer cells, they make the body hot and reduce the nutritional resources that cancer cells can get, also renew the proteins in the body and improve one’s mood, cancer cells are hard to live when one is activ...

 From Bronchial Asthma to Tuberculosis: Unravelling the Cytokine-Macrophage Axis in Diverse Diseases Cytokines, tiny proteins secreted by cells, play a critical role in mediating communication and interactions between cells. They also function as immunomodulating agents, adjusting immune responses. When released into the bloodstream or tissues, cytokines bind to specific receptors on target immune cells, triggering cellular responses. Cytokines are implicated in various diseases, including asthma, COPD, HIV infection, and multiple sclerosis. This review delves into the intricate interplay between cytokines and macrophages, focusing on their roles in inflammation and the immune response. Macrophages, which are scavenger cells of the immune system, exhibit remarkable heterogeneity, reside in diverse tissues, and play crucial roles in both innate and acquired immunity. They can be activated for proinflammatory or anti-inflammatory functions, contributing to tissue destruction or regen...
