(Universidad Austral de Chile, 2020)In dairy cattle, genetic selection for milk yield was generally based on 305 days lactation records that were calculated from available monthly test-day milk yield records. A test-day milk yield record, multiplied by the ...
-
(Elsevier, 2014)Evapotranspiration (ETd) is a key controller in the ecohydrological processes of semi-arid landscapes. This is the case of the dry land in Chile’s central-southern zone, where forestry, farming and livestock activities ...
-
(Instituto de Investigaciones Agropecuaria, 2014)Crop evapotranspiration (ETc) is essential for irrigation scheduling. The amount of water consumed can be estimated by multiplying the reference evapotranspiration (ET0) by a crop coefficient (Kc); the value of Kc is ...
-
(Springer, 2015)Chile needs to diversify its energy supply, and should establish policies that encourage the production and use of biofuels. The demand for energy resources increases with population growth and industrial development, ...
-

(2010-03)A non-destructive impact sensor to measure on-line fruit firmness was evaluated. This sensor is an adaptation of a static model used in the laboratory to measure fruit quality and was installed in an experimental fruit ...
-
(SOC. chilena ciencia suelo, 2018-03)The control of iron chlorosis by synthetic Fe chelates is costly, and their application can have adverse environmental impacts. We investigated the effectiveness of alternative strategies to prevent Fe chlorosis in avocado ...
-
(2014)One of the major problems for biodiesel producers is the disposal of the seed cake after expelling oil from seeds. Every ton of biodiesel results in 2.5 to 3 tons of seed cake as byproduct. The physicochemical characteristics ...
-
(ELSEVIER SCIENCE BV, 2008-10)Direct measurement of soil saturated hydraulic conductivity (Ks) is time-consuming and therefore costly. The ROSETTA pedotransfer function model is able to estimate Ks from soil textural data, bulk density and one or two ...
-
Evaluation of impacts of management in an anthropogenic peatland using field and remote sensing data (ESA, 2015)Peatlands are a type of wetland characterized by the accumulation of organic matter, called peat, and are important carbon reservoirs. In areas with poor drainage, human-induced forest fires and logging can produce flooded ...
