In the framework of Sustaffor project (FP7-Research for SMEs, 2013-2015) a network of 8 field trials was installed, comprising almost 4,000 trees in four strongly contrasted bioclimatic areas: Semiarid, Mediterranean continental, Mediterranean humid and Montane.

These trials aim at assessing the individual and combined effects of innovative novel techniques targeting at improving the environmental, technical and economic outcomes of tree planting projects at Mediterranean and temperate conditions. These techniques were developed by 4 European SMEs:

  • A new soil conditioner developed by TerraCottem Internacional, with an improved mixture of hydroabsorbent polymers, root growth precursors and fertilizer: this technique improves water and nutrient availability at micro-site level, being an alternative to existing soil conditioners, soil amendments and emergency irrigation.
  • Four new mulching models: two versions of a new biopolymer-based biodegradable mulch (DTC); a woven jute biodegradable mulch treated with bio-based resins for enhanced durability (La Zeloise) and a long-lasting (reusable) mulch made with recycled rubber (EcoRub). These models pretend to avoid weed competition during the first years of plantation, being an alternative to chemical or mechanical weeding and to plastic mulching.

We present and discuss the performance of these novel techniques, compared to reference ones, during the first vegetative period (2014) on tree survival, growth & physiology and soil moisture. The novel techniques have proven to be a feasible alternative under different circumstances: soil conditioner was especially effective in limited sites (semiarid and montane) while mulching resulted in noticeable gains at the most productive sites (Med continental and Med humid).

Key words: eco-innovation, environmental friendly, groundcovers, SMEs, biodegradable.
