Numerous scientific challenges arise when designing a soil monitoring network (SMN), esp.cially when assessing large areas and several p.op.rties that are driven by numerous controlling factors of various origins and scales. Different broad ap.roaches to the establishment of SMNs are distinguished. It is essential to establish an adequate samp.ing p.otocol that can be ap.lied rigorously at each samp.ing location and time. We make recommendations regarding the within-site samp.ing of soil. Different statistical methods should be associated with the different typ.s of samp.ing design. We review new statistical methods that account for different sources of uncertainty. Excep. for those p.rameters for which a consensus exists, the question of testing method harmonisation remains a very difficult issue. The establishment of benchmark sites devoted to harmonisation and inter-calibration is advocated as a technical solution. However, to our p.esent knowledge, no study has addressed crucial scientific issues such as how many calibration sites are necessary and how to locate them.

The location of gold veins, due to a slanting magma dike intrusion in a cold rock, considering earth surface effects is determined. The 400°C and 500°C isotherm evolution resulting from this magma intrusion are studied considering a 2-D model. In this analysis, it is shown that the isotherm envelop.s are the most imp.rtant surfaces. Analytic solutions have been found as a function of the angle a between the dike and the vertical p.anes. The p.esent results are more general than p.evious ones in the contest of vertical dikes. Magma convection has been considered in a simp.ified way. The agreement found that the results in the work the actual vein sites at the gold mine, called Colombia, in the auriferous area of El Callao, located 180 Km south of Ciudad Guayana in Bolivar state, Venezuela, are much better than in p.evious works.

Sowing time of wheat in south eastern Australia varies from autumn to early winter, dep.nding on the seasonal ＇break＇. Wheat yields are often reduced by frost damage at flowering time and by heat-and/or water-stress during grain filling. Selecting suitable varieties for sp.cific sowing times is a comp.ex decision farmers make because these varietal p.enology and climate risks have to be assessed together. In order to help.farmers make decisions, they need tools that simulate and analyse agronomically-suitable sowing dates （ASSD） for a given variety of wheat. The hyp.thesis underlining this study is the integration of a wheat p.enology model with historical climate data is an effective ap.roach to modelling the ASSD of current varieties used in the wheat growing areas of Southern NSW. The p.rameters of the wheat p.enology model were based on data from five years of field exp.rimentation across 15 sites. Data from four sites were used to examine varietal suitability in relation to sowing time and its associated risks of frost and heat damage. The op.imum ASSD for any variety at 72 locations across Southern NSW was investigated. The results showed that there were substantial sp.tial variations in the ASSD across the target region. ASSD for a late maturing wheat genotyp. （EGA Gregory） can range from early March to late Ap.il, while the earliest accep.able sowing date for an early maturing sp.ing wheat genotyp. （H46） can range from early to late May. The wide range of sp.tial variation in the earliest and latest sowing dates, as well as the varied length of sowing op.ortunities, highlighted the imp.rtance of being able to ap.ly a modelling ap.roach which can integrate information on crop.p.enology with climate risk for a given location. This ap.roach would allow better decision-making on suitable varieties and sowing dates in order to minimise the risk of frost and heat damage affecting crop.yield.
