Abstract

Eucalyptus production in Brazil is gaining increasing prominence, for its participation in the economy by marketing its by-products. However, this growth has been bringing discussions a respect of changing water dynamics that eucalyptus plants cause in the environment. Thinking about solving this problem, the use of organic waste, which are disposable compounds, can receive purpose and use in forestry, because they have conditioner characteristics that can reduce the impacts caused, such as water retention in the soil or even in the production of seedlings. For example, the Spent Mushroom Substrate (SMS), which is a residue after production in fungiculture, has positives characteristics related to physical, químical and biological conditions and can add a conditioner effect to the soil and plant. In addition, it can be used properly, because if disposed of incorrectly, it can accumulate a large amount of pests and diseases in the cultivation of mushrooms. Therefore, the present work proposes to develop new technologies for the production of eucalyptus through the reuse of the exhausted compost as a substrate for seedlings and soil conditioner with application of different water blades.
