Última COMPARATIVE ANALYSIS OF SPLIT-WINDOW ALGORITHMS FOR ESTIMATING SOIL TEMPERATURE R.C. Suelo Nutr. Veg. Vera,Leonardo; Parra,Juan C; Morales,Luis; Mattar,Cristián; Jorquera-Fontena,Emilio. The ability to estimate soil temperature (Ts) from satellite information is highly useful, since this is one of the main input variables in various models designed for estimating biophysical parameters. A comparative analysis is made of various Split-Window algorithms used to estimate soil temperature from data provided by the Advanced Very High Resolution Radiometer (AVHRR) sensor on board of satellites of the National Oceanic and Atmospheric Administration (NOAA). The algorithms compared are those proposed by: Prata and Platt (1991); Uliveri et al. (1992); Sobrino et al. (1993); Caselles et al. (1997); Sobrino and Raissouni (2000). The temperature estimates were validated with data of the soil temperature in situ recorded in a data logger installed in a...

The main challenges confronting contemporary agronomy are being addressed according to the emerging and complex problems of our era. Agronomy corresponds to the science and profession of solving the problems ofagriculture. The emergence of agronomy in sociocultural processes and their coevolution is described, as agronomy represents the determinant for the artificialization of nature, the management of natural resources and the transformation and management of land. The integration of nature, culture and human well-being inform the tendencies that are expressed in the cultural landscape. Ecology, ecosystem, territory and cultural landscape are the resultant aspects that provide the basis for the study and development of natural resource and ecosystem...

Ano: 2012 URL: http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0718-16202012000300001 Sustainable Agriculture: Unifying Concepts Ciencia e Investigación Agraria Gastó,Juan; Vera,Leonardo; Vieli,Lorena; Montalba,Rene. This work is the product of a long process that tried to approximate the principia involved in sustainable agriculture in an attempt to analyze it. We believe that these principia are crucial for the systematic, rigorous, and consistent development of sustainable agriculture. The unifying concepts of agriculture sustainability are classified into seven fundamental principies: (i) there is a hierarchy in decision-making with respect to human actions on the landscape and environment; (ii) human impact on the land should be analyzed from different perspectives (local, global, anthropocentric, and ecocentric); (iii) the carrying capacity in an agrarian context is crucial to ecosystem management and design; (iv) humans arrange nature with little consideration...

L. Vera, R. Montalba, L. Vieli, E. Jorquera, and I González. 2015. Methodology for determining the suitability of land for the cultivation of highbush blueberry: a case study on a farm in southern Chile. Cien. Inv. Agr. 42(3): 353-364. The selection of good planting sites is critical for the success of blueberry plantations. The objective of the present study was to identify farm territorial units suitable for the establishment and management of highbush blueberry crops on a farm in southern Chile. A farm-level characterization was developed, and districts and sites were classified according to their receptive capacity. Numerical suitability valúes were subsequently obtained for each land unit identified on the farm. Four suitability categories were...
