Agricultural Meteorological Elements and their Observations

Agricultural meteorology is concerned with every aspect of local and regional climates and the causes of their variations, thus making standard observation of climatic elements a fundamental necessity (e.g. . It is also concerned with any climatic modifications which may be introduced by human management of agriculture, animal husbandry or forestry operations (e.g. Stigter, 1994a). Physical elements of climate are observed to assist the management of agricultural activities. Such management includes determining the time, extent and manner of cultivation and other agricultural operations (sowing, harvesting, planting, application of biocides and herbicides, ploughing, harrowing, rolling, irrigation, suppression of evaporation, deign, construction and repair of buildings for storage, animal husbandry etc.) and different methods of conservation, industrial use and transportation of agricultural products.

Disease-warning systems are decision support tools designed to help growers determine when to apply control measures to suppress crop diseases. Weather data are nearly ubiquitous inputs to warning systems. This contribution reviews ways in which weather data are gathered for use as inputs to disease-warning systems, and the associated logistical challenges. Grower-operated weather monitoring is contrasted with obtaining data from networks of weather stations, and the advantages and disadvantages of measuring vs. estimating weather data are discussed. Special emphasis is given to leaf wetness duration (LWD), not only because LWD data are inputs to many disease-warning systems but also because accurate data are uniquely challenging to obtain. It is concluded that there is no single "best" method to acquire weather data for use in disease-warning systems; instead, local, regional, and national circumstances are likely to influence which strategy is most successful.

INTRODUCfION This bibliography of the agricultural climatology literature includes many aspects of the broad field of agricultural climatology. Much overlapping with related fields occurs. Topics related to agricultural climatology include crop and animal physiology, agricultural meteorology, general climatology and meteorology, and statistics. This bibliography was created to help researchers and students interested in obtaining historical and current literature in the field of agricultural climatology. The period of record of these references is 1735-1987. This bibliography is divided into two parts. Part I deals with agroclimatological topics for field crops such as cotton, maize, millet, rice, sorghum, soybeans, sunflower; horticultural crops such as vegetables, fruits and turf; forages, pasture, and hay; and livestock. This volume, Part II,deals with more general and non-crop-specific topics in agricultural climatology such as water, drought, eva};X)rationand eva};X)transpiration,crop water use and requirements, temperature and solar radiation, heat units, plant res};X)nseto climatic stress, climatic normals and analysis, crop yield models and forecasting, climatic and agroclimatic classification, agrometeorology, phenology, agroclimatic information gathering and dissemination, agroclimatic assessments, and statistics and computers in agroclimatology. The entire bibliography (Parts I and II) is continually up:lated and available in Professional File 1 and Lotus 123 2 formats for the IBM pc3 and can be obtained by sending a 5 1/4" or 3 1/2" diskette to the author.

Information is nowadays one of the crucial elements of contemporary life, and its accessibility affects frequently the possibility of decision making and managementat the top administration level as well as at the level of a particular system user. Modern agriculture, as other spheres of activity, needs actual information supporting end users (farmers and agricultural advisors) in their decisions and activities. Agrometeorological services facilitates better use of meteorological conditions in planning individual works and more efficient plant protection. Furthermore this data can lead also to yield increase. In Poland, the agrometeorological service is provided by the Institute of Meteorology and Water Management-National Research Institute (IMGW-PIB). In the article, the Polish Agrometeo service and its planned development is described in details. Also some problems and recommendations concerning the service development are listed.

The quantified meteorological observations are important in agriculture to increase productivity. One of the instruments used are automatic weather stations. Stations used in Mexico, generally acquired technologies in developed countries, so that, when the equipment brakes, cannot be repaired because of the cost and lack of knowledge. For agricultural research, most commercial stations are not always the most appropriate, since they are no adjustable parameters required for the research. This paper presents the development of a prototype of an automatic weather station by students from the Technological Institute of the Laguna, which can be adjusted to different sensors and sampling times. Also, the installation of the prototype is detailed in the experimental field of Antonio Narro Agrarian Autonomous University, Unit the Laguna, followed by the statistical validation obtained by correlating readings to historical prototype of two commercial stations installed in a smaller radius than 10 km. Global radiation for a correlation of 0.95 and 0.91 temperature was obtained. Finally scope and limitations of the prototype in agriculture are also analysed.
