  Modern Techniques in Horticultural Research  - (MTHR)|  Stephy Publishers 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 signifi...

  Modern Techniques in Horticultural Research - (MTHR)| Stephy Publishers Abstract The move towards a de-carbonised world, driven partly by climate science and partly by the business opportunities it offers, will need the promotion of environmentally friendly alternatives, if an acceptable stabilisation level of atmospheric carbon dioxide is to be achieved. This requires the harnessing and use of natural resources that produce no air pollution or greenhouse gases and provides comfortable coexistence of human, livestock, and plants. This study reviews the energy-using technologies based on natural resources, which are available to and applicable in the farming industry. Among these are greenhouses, which are necessary for the growth of some plants (i.e., vegetables, flowers, etc.) in severe climates. However, greenhouses require some air conditioning process to control their temperature and relative humidity to suit specific plants. To achieve this, a novel air humidifier and/or de...
