Growing plants in general and Jatropha curcas L. in particular requires knowledge and understanding of the environmental conditions these plants require to grow and thrive. Regarding the factors influencing plant growth, an understanding of soils probably is the most important one. In subtropical and tropical areas (this is where Jatropha belongs) variation in soil type, pH, and nutrient content is huge. In the case of growing Jatropha it is even more crucial to understand (at least) the soil conditions since there is very little specific information about Jatropha soil conditions itself. Another important factor of cours are the climatological conditions rain and temperature.
