Evaluation of chañar seed cake from biodiesel production as a soil amendment

One of the major problems for biodiesel producers is the disposal of the seed cake after expelling oil from seeds. Every ton of biodiesel results in 2.5 to 3 tons of seed cake as byproduct. The physicochemical characteristics of this residue indicate that it could be converted into valuable organic...
