How to select plants for degraded areas and erosion control?
DEFLOR Bioengineering provides in this section for its customers, professionals and interested parties the selection of plants according to the location and situation of the impacted area. Just fill in the data of the company/professional and data regarding soil type, climate, plant desirable characteristics, items which rise any doubt should remain uncompleted.The Technical Sales Department will assess the information and email all of the possible alternatives of selected plants, and the technician will choose the species with 1, 2 or more unanswered criteria. The quantities of seeds provided are for single species, and the actual quantities will be calculated and divided by the number of selected species.

In the case of vetiver grass, the planting should be done preferably in row lines, and across to the area steepness, based on 6 to 8 plants/linear meter, and each row should be spaced 1 to 3 meters wide. For species whose planting/sowing is done by seeds, the technician may refer to the characteristics stated in the Selection Report to check for the planting methods and analyze the seed cultural value, thus avoiding any future trouble. The amount of seeds to be applied was calculated based on the cultural value indicated, and if the cultural value is lower, the amount should be added in the same proportion.

The report issued by computer is sent to the client, with the respective amounts of seeds, cultural value and species. The amount of seeds indicated should be divided by the number of selected species, and the species selection will be based on the number of unanswered attributes, i. e., by technical criteria, species with 1 or more unanswered criteria, according to the local situation, experience or customer need, may be selected.
