Influence of Various Soil and Water Conservation Methods on the Moisture Balance at Coffee Plant Root Zone

Background: The study of the moisture balance can be used to suppose the plants water requirement and the plants water use efficiency. The moisture balance influenced by climate factor, therefore climate change can affect the moisture balance especially in rainfed. Therefore, an effort is needed to manage soil moisture in rainfed as a climate change mitigation measure: soil and water conservation. This study aimed to determine the influence of soil and water conservation on the moisture balance in the coffee root zone. Methods: This study was conducted at people’s coffee plantation of Argotirto village, Sumbermanjing Wetan District, Malang Regency, located between 8.2411-8.1443 S and 112.4031-112.4634 E. Observation were made on February to November 2020, divided into observations in the wet season, dry seasons and flowering period. The observation plots consisted of terraced plot (P0), terraced + straight silt pit (P1), terraced + L-shaped silt pit (P2) and terrace + biopore (P3). The observation variables were: soil physical characteristics and moisture balance components there were precipitation, percolation, runoff, evapotranspiration and soil moisture storage. Result: At P1, the runoff depth was 80.89% lower and the percolation was 44.22% higher than P0. The total soil moisture storage at P1 was 20.06% higher than P0 in the dry season, indicating that P1 could increase the period of surplus moisture in the dry season.

Application of Multi-dimensional Technology in Water Conservation Monitoring of Power Transmission and Transformation Production and Construction Project

Under the background of the new era, as the production and construction projects of soil and water conservation began to fully promote the “integration of heaven and earth”, the traditional application technology has been unable to meet the needs of practical development, and the power transmission and transformation production and construction projects put forward higher application requirements. Therefore, on the basis of understanding the current implementation of soil and water conservation monitoring work, this paper analyzes how to reasonably use UAV technology in practical monitoring work according to the multi-dimensional technical means proposed in the new era, and conducts performance analysis according to the practical verification.
