Assessing saturated hydraulic conductivity from the dielectrically-predicted dry bulk density
Provedor de dados: 111
Autores: WIJAYA, Krissandi; Kuncoro, Purwoko Hari; Nishimura, Taku; Setiawan, Budi Indra.
Direct measurement of saturated hydraulic conductivity (Ks) and dry bulk density (rb) is often laborious, time consuming, and expensive. Predicted dry bulk density (rb-ADR) using Amplitude Domain Reﬂectometry (ADR) probe has been employed to predict saturated hydraulic conductivity (Ks_ADR) after a slight modification on the previously available Non-Similar Media Concept (NSMC) model. All the predicted values were validated using the corresponding measured data of 108 undisturbed samples for each of 0-15 and 15-30 cm soil depths observed. The proposed “Dielectric NSMC” model could describe rb_ADR dependencies of Ks_ADR better than the other proceeding models for the both ranges of soil depths observed. The proposed model tended to slightly underestimate...

Almost all countries in the world have used lettuce hydroponic cultivation in planthouses because it is appropriate for plant growth and production. The microclimate inside planthouse is an environmental factor that affects plant growth and development. Vegetables planted in the planthouse have a great deal of water requirement. Selecting a method with a more accurate estimation of crop evapotranspiration is a critical factor for efficient water management. In this research, the climates that are affecting the lettuce evapotranspiration with modification of floating hydroponic technique inside the planthouse were investigated. The objectives of this research are to figure out the microclimate, the appropriate model of the potential evapotranspiration, and...

Water application in the plant house is usually done by surface irrigation and manual micro-irrigation. Because of the conventional irrigation system’s inefficiency, water-saving irrigation has been developed. Smart or automated irrigation usually uses a microcontroller to maintain irrigation timing and soil moisture conditions. This automation is highly efficient in water application and can increase plant productivity. However, this system is costly and the irrigation components are not always available for smallholder farmers. Here we develop an automatic irrigation technology based on the capillarity principle that dramatically reduces the cost. This irrigation technology does not use any microcontroller device and the components can be easily...
