Abstract
 
An automatic water management system for agriculture land was developed based on mini PC as controller to manage irrigation and drainage. The system was integrated with perforated pipe network installed below the soil surface to enable water flow in and out through the network, and so water table of the land can be set at a certain level. The system was operated by using solar power electricity supply to power up water level and soil moisture sensors, Raspberry Pi controller and motorized valve actuator.
 
This study aims to implement the system in controlling water level at a soybean production land, and further to observe water footprint and carbon footprint contribution of the soybean production process with application of the automated system. The water level of the field can be controlled around 19 cm from the base. Crop water requirement was calculated using Penman-Monteith approach, with the productivity of soybean 3.57t/ha, total water footprint in soybean production is 872.01 m3/t. Carbon footprint was calculated due to the use of solar power electric supply system and during the soybean production emission was estimated equal to 1.85 kg of CO2.

Solid Biomass Supply for Heat and Power: Technology Brief

Solid biomass from forests, farms and cities provides a major energy source for heat and power generation, potentially accounting for a fifth of global energy consumption by 2050 amid accelerated adoption of renewables. But wood and crop residues need to be collected from widely dispersed sites and stored for use at the optimal time, and at a cost-effective scale, in district-heating systems, power plants, and combined heat and power plants.
