Description
Summary:The adoption of in-situ soil and water conservation techniques are the need of the day all over the country. Taking into consideration this logic, the experiment on practical implementation of the conservation measures along with impact assessment was undertaken at AICRP for Dryland Agriculture Dr. PDKV, Akola. In which impact assessment of continuous contour trenches (CCTs) on hydrological, agronomic, soil nutrient status has been made. In this paper the results related to soil nutrient losses are presented. The small catchment was divided into two parts one is treated with CCTs and other is without CCTs. From the recorded data and nutrient status analysis, it was observed that in CCT treated (T1) micro-catchment Nitrogen, Phosphorous and Potassium was more by 25 %, 15.31% and 9.96% respectively over untreated (T2) micro-catchment. The micro-nutrients viz. Zinc, Ferrous, Magnesium and Copper in CCT treated micro-catchment was observed more by 15.56 %, 7.70%, 23.07% and 37.54% respectively over untreated (T2) micro-catchment. The pH and EC was also observed to be more in CCT treated (T1) micro-catchment as compared to untreated (T2) micro-catchment. These results conclude that in CCT treated micro-catchment the losses of nutrients had been reduced which ultimately useful for plant growth. Thus continuous contour trenches are useful for conservation of soil nutrients.
