Assessing environmental impacts of rehabilitated Degraded uplands in watershed with Jatropha plantation
For sustainable development and optimal use of natural resources environmental consideration are required to be integrated in planning, designing and implementation of development projects.
Using chemical fertilizers and pesticides for increased agricultural productivity has led to intensive cultivation of marginal lands and there-by-there degradation. Vegetation measure is one of the most practical and economical methods for pollution control and land reclamation but often difficult and slow due to the hostile growing conditions.
As Jatropha is a plant, which can grow in dry region, and able to grow on degraded uplands it can be a good candidate to rehabilitate the degraded lands. The present work focused on the study of Environmental Impacts due to Jatropha plantation in degraded lands in two villages i.e. Velchal and Kothlapur planted at revenue lands.
Studies on the microbial parameters, various psychochemical and biological parameters of the soil samples with and without Jatropha plantation were studied using standard procedures. It was observed that the soils in presence of Jatropha plantation enhanced the mean microbial population (%), soil moisture content (%) and particle density over the control soils.
It was observed that the soil nutrients such as potassium, phosphorus, zinc, boron and sulfur were lower in Jatropha plantation soils than in control soils.
