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
in all FBO treatments., MenosIn tea plantations of Southern China, a pilot experiment using the FBO technology was installed

The feasibility of thermography as a technique for plant screening aiming at drought-tolerance has been proven by its relationship with gas exchange, biomass, and yield. In this study, unlike most of the previous, thermography was applied for phenotyping contrasting maize genotypes whose classification for drought tolerance had already been established in the field. Our objective was to determine whether thermography-based classification would discriminate the maize genotypes in a similar way as the field selection in which just grain yield was taken into account as a criterion. We evaluated gas exchange, daily water consumption, leaf relative water content, aboveground biomass, and grain yield. Indeed, the screening of maize genotypes based on canopy temperature showed similar results to traditional methods. Nevertheless, canopy temperature only partially reflected gas exchange rates and daily water consumption in plants under drought. Part of the explanation may lie in the changes that drought had caused in plant leaves and canopy structure, altering absorption and dissipation of energy, photosynthesis, transpiration, and partitioning rates. Accordingly, although there was a negative relationship between grain yield and plant canopy temperature, it does not necessarily mean that plants whose canopies were maintained cooler under drought achieved the highest yield. |
