I would like to know the prize of the Jatropha Curcas seeds. I am from Argentina (South America) and I am very interested in buying large amounts of them. I would also be very grateful to receive some information about the following aspects: 1- Which type of Jatropha do you supply, the toxic or the non toxic one? 2- Which is the maximum amount of Jatropha seeds that I can get from you? 3- Which is the better way of transportation in terms of costs? 4- How many kilogrammes do I need to cultivate one hectare with a density of 1650 plants (2 x 3 mts spaced) per/ha? 5- Do you supply information about the cultivation process, climate, soil, etc? Thanks, Carlos Motura
