In some part of my land the soil is shallow (depth is only 1.5 to 2.5 feet) and some calcareous rocks/hard rocks can be seen. This is almost >1 Acre and want to make it useful. I was planning to grow Casuarina Tree in very shallow place 1 to 2 feet soil depth and other plans timber trees like Kumil, Terminalia arjuna and few other native trees. Please let me know if you have any suggestion on what can grow in these type of lands. I don't want to do seasonal crops or fruit trees. Appreciate your response.
