No RAIZ procuram-se soluções para uma<br />

maior eco-eficiência <strong>da</strong> Indústria.<br />

RAIZ looks for the best eco-efficiency solutions.<br />

No âmbito do trabalho <strong>de</strong>senvolvido ao nível<br />

<strong>da</strong> Investigação Aplica<strong>da</strong> — tanto na área<br />

tecnológica como florestal — <strong>da</strong> Consultoria<br />

e <strong>da</strong> Formação, muita <strong>da</strong> acção do RAIZ tem<br />

incidido sobre soluções que favorecem uma<br />

exploração sustentável <strong>da</strong> fileira florestal.<br />

Para isso tem concebido ferrament<strong>as</strong> que<br />

permitem o diagnóstico do solo e do estado<br />

nutricional dos povoamentos <strong>de</strong> eucalipto o que,<br />

a médio prazo, garante uma exploração<br />

equilibra<strong>da</strong> <strong>da</strong> floresta e a utilização dos<br />

terrenos mais a<strong>de</strong>quados a ca<strong>da</strong> tipo <strong>de</strong><br />

produção. Para chegar a este ponto, foram<br />

essenciais os trabalhos <strong>de</strong> zonagem<br />

<strong>de</strong>senvolvidos nos últimos anos, com<br />

a caracterização dos solos em tod<strong>as</strong> <strong>as</strong><br />

Nos primórdios <strong>da</strong> indústria <strong>da</strong> p<strong>as</strong>ta e do papel,<br />

em alguns c<strong>as</strong>os, po<strong>de</strong>ria trazer resultados<br />

inesperados. O trabalho do RAIZ permite,<br />

In the scope of Applied Research — both in the<br />

are<strong>as</strong> of technology and forestry — Consultancy<br />

and Training, a great <strong>de</strong>al of the work un<strong>de</strong>rtaken by<br />

RAIZ h<strong>as</strong> been focused on the provision of solutions<br />

which promote a sustainable forest chain.<br />

Hence, it h<strong>as</strong> <strong>de</strong>signed the necessary tools to<br />

diagnose the soil and nutritional conditions of the<br />

eucalyptus plantations, which in the medium<br />

term, will guarantee a well-balanced operation<br />

of the forestry area and the choice of land that is<br />

more appropriate for each specific production.<br />

To reach this stage, it is fun<strong>da</strong>mental to<br />

un<strong>de</strong>rtake soil zoning works throughout the<br />

Portucel Soporcel group´s property, a t<strong>as</strong>k that<br />

will take several years to complete.<br />

In the early <strong>da</strong>ys of the pulp and paper industry,<br />

it w<strong>as</strong> impossible to estimate the levels of<br />

productivity, water consumption or nutritional<br />

needs of each specific planted area, which in<br />

some c<strong>as</strong>es led to unexpected results. The<br />

activity performed by RAIZ not only <strong>de</strong>fines the<br />

soil’s chemical properties, but also its stone<br />

content, slope or nutritional needs, through the<br />

characterisation of soil samples. Once this<br />

information is matched with the available <strong>da</strong>ta on<br />

the climate conditions in the different are<strong>as</strong>, it<br />

will i<strong>de</strong>ntify homogeneous soil zones, after which<br />

it can be <strong>de</strong>ci<strong>de</strong>d which species to plant. As the
