  abstract = {{C}ollaborative research in the {M}acrofauna project has enabled development of some techniques that presently are at different stages of advancement, from promising pilot experiments (tomato production and inoculation in plant nursery bags at {Y}urimaguas and in {I}ndia) to the fully developed technique of massive worm production and biofertilization of tea gardens in {T}amil {N}adu ({I}ndia) (patent deposited). {F}ailures have also helped to gain better insight into the potential feasibility of techniques that had been considered in the objectives of this project. {E}ndogeic earthworms (#{P}ontoscolex corethrurus$) may be produced in large quantities, i.e.about 12000 worms (1.6-2.8 kg live wt)/m2/year in specific culture beds using either sawdust ({Y}urimaguas, {P}eru) or a mixture of high and low quality materials ({T}amil {N}adu, {I}ndia) mixed into soil as substrates. {C}ost of production of 1 kg of earthworm biomass through bed culture is about 3.6 {E}uro, much lower than the cost of hand collection of worms from pastures/grasslands where these species are abundant (6-125 {E}uro depending on the cost of labour and earthworm density). {T}he theorical value of an active earthworm community with an average biomass of 400 kg live wt has been estimated at 1400 {E}uro, the price that it would cost to reintroduce an equivalent biomass produced in our culture units, indicating the cost of land restoration. {D}irect inoculation of earthworms in the field to improve production may only affect plant growth positively if a large biomass (greater than 30 g live wt/m2) is inoculated from the beginning. {A}n alternative may be to concentrate the inoculum in small areas regularly distributed across the field...
