In tea plantations of Southern China, a pilot experiment using the FBO technology was installed
in three replicated plots 15x30 m each allocated to four different treatments: control, FBO with
full organic fertilisation and no pesticide application, FBO with 50% inorganic fertilization, with
application of either chemical or bio pesticides. FBO restores soil function by creating small
islands with full ecological functionality in a degraded soil. The islands are trenches 1.5m in
length, 30cm wide and 45 cm deep, filled with soil and two sorts of organic matter of contrasted
qualities and inoculated with earthworms. The choice of earthworms and organic matters and
their specific spatial array are key elements for the success of the technology.
Macro fauna communities were greatly changed after one year. Ants were no longer over dominant
in FBO treatments since the abundance and diversity of termites, Diplopoda and predators had
significantly increased. After 18 months, macro fauna abundance was 240 ind m-² in FBO
trenches and 370 on average in the control plot. Earthworms were only found in FBO treatments.
The FBO increased soil aggregation in the three layers (0-10; 10-20; 20-30 cm); total abundance
of macro aggregates was increased 11.7 times in the FBO 100% as compared with the
conventional plot. Effects were more important in deep layers (10-30cm) than surface layers (0-
10). Biogenic aggregates mainly made by earthworms comprised over 30% of total aggregation

Popularly known as pupunha, Bactris gasipaes Kunth is a palm tree native to the Amazon region whose planting has extended to the Southern and Southeastern states of Brazil. The production and consumption of peach palm generate a huge volume of by-products. It is estimated that approximately 84% of the total weight of the palm are lignocellulosic wastes. The white-rot fungus Pleurotus ostreatus was used for biological pretreatment of peach palm lignocellulosic wastes (inner sheath and peel) for improving the enzymatic saccharification and production of glucose. Non-treated and pre-treated B. gasipaes inner sheath and peel were submitted to hydrolysis by a commercial cellulase preparation from T. reesei. The amounts of total reducing sugars and glucose obtained from the 30d-pretreated inner sheath were seven and five times superior, respectively, when compared to those obtained with the non-pretreated inner sheath. However, the pre-treatment did not cause any improvement in the saccharification of the B. gasipaes peel. Scanning electronic microscopy of lignocellulosic fibers was done to verify the structural changes caused by the biological pretreatments. Upon the biological pretreatment the lignocellulosic structures of the inner sheath were substantially modified to less ordered ones. The main features of the modifications were detachment of the fibers, cell wall collapse and, in several cases, formation of pores in the cell wall surfaces. The peel lignocellulosic fibers showed more ordered fibrils and no modification was observed after pre-treatment. In conclusion, P. ostreatus pretreatment considerably improved saccharification of the B. gasipaes inner sheath (7-fold), but ´pretreatment of the peel was largely ineffective.
