The issue addressed relates to an area of 1891694 ha of which 1183343 ha are agricultural land (62, 56) located in the south-west of Romania and refer to the use of soil chemical and physical properties as an acceptor for certain crop systems, with minimal undesirable effects both for plants to be grown, as well as soil characteristics and groundwater surface quality. It is therefore necessary on a case-by-case basis, measure stoc or rect the acidic reaction by periodic or alkaline calculations, the improvement of plant nutrition conditions through ameliorative fertilization and the application of measures to improve the physical state, sufficient justification for the need to develop short and long term strategies for the protection and conservation of edifying factors and the need to respect the frequency of field and laboratory investigations at all 8x8 km grids of the National Soil-Grounds Monitoring System (organized by I.C.P.A.) and completing it with the relevant pedological and agrochemical studies.

Abstract Data on land use in Maine are assembled from USDA Forest Service inventories, the Census of Agriculture, and other sources. Regression analysis is used to estimate the relationships between land use and determinants of land use such as land rents and soil characteristics. The fitted models are used to project changes in land use to 2050. We project declines in private timberland area, though these losses are small on a percentage basis. Continued declines in agricultural land area and increases in urban land area also are projected. Land use policies that influence land rents such as preferential tax assessment programs can be used to deter socially undesirable land use changes. North. J. Appl. For. 16(2):82-88.

South Moravia

To analyse the potential changes in soil characteristics and associated impacts on the land price, the region of South Moravia was selected, strongly threatened by erosion and by claiming the most valuable land in suburban territories due to industrial and housing expansion. For the detailed analysis of the impacts of erosion and land appropriation in the region of South Moravia, the model territories of Brno surroundings with the municipality of Dolní Heršpice and Hustopeče surroundings with the municipality of Starovice were selected. The price of land degraded by potential erosion in the South Moravian region fluctuates between 88 and 2 400 EUR/ha. In the past 180 years, 148 ha of agricultural land in the total value of 822 815 EUR have been used for construction in the location under study in Dolní Heršpice. Further growth of the municipality should involve additional appropriation of agricultural land in the value of 411 000 EUR. In the studied land block of 100.5 ha, located in the Starovice municipality area, water erosion caused degradation in the total value of 92 000 EUR in the period 1978–2013. Extensive losses of fertile agricultural land are to be expected in the future. Their main causes are continuing land appropriation and degradation processes – soil erosion.

The efforts to utilize the agricultural land need a proper understanding of the soil characteristics. The soil characteristics themselves are influenced by the factors that regulate and control the soil forming and pedogenesis processes. The main soil forming factors in this study was the different ages and composition of parent materials from the eruption of Mt. Tangkuban Parahu in West Java. This research was done to comprehend the pedogenesis and to figure out the soil classifications that developed in two geological formations (Qyd and Qvu) and two ages of eruption (Holocene and Pleistocene) of Mt. Tangkuban Parahu. The study was conducted in Ciater, Subang Regency and Jatinangor, Sumedang Regency in West Java Province. The study consisted of four stages: preparation, field survey and soil sampling, laboratory analysis and presenting the report. The results showed that Pedon of Jatinangor consisted of three different stratifications of ages. The clay mineralogical composition was dominated by kaolinite, whereas mineralogical composition of the sandy fractions (heavy fractions) was augite-hypersthene. Pedon of Ciater also consists of three different stratifications of age. The clay mineralogical composition was dominated by allophane, while mineralogical compositions of the sandy fractions (heavy fractions) were green amphibole-hypersthene in the overlying horizons and amphibole-augite in the underlying horizons. The stage of soil formation on both pedon were cambic or viril. The soil classification according to Soil Taxonomy were Acrudoxic Durudands, medial over loamy-skeletal, isohyperthermic in Ciater Pedon and Fluventic Eutrudepts, fine, kaolinitic, isohyperthermic in Jatinangor Pedon.Key words: slow sand filter, activated carbon, silica sand, sand, gravel, zeolite

Spring Snowmelt

There are few computer models that can simulate winter freeze–thaw conditions and spring snowmelt hydrology for agricultural tile drained lands. DRAINMOD, which is used widely to simulate tile drainage flows, has not been extensively applied during colder periods in eastern Canada. This study analyzes the performance of DRAINMOD for surface runoff and subsurface drainage predictions in southern Quebec during spring snowmelt. The model was tested with five years of field data. DRAINMOD was found to be adequate in predicting spring snowmelt hydrology, except for subsurface drainage at one site. It was found that soil characteristics had a major influence on model performance.

Earthquacke on 30th of September 2009 in West Sumatra had ruined Padang Pariaman, Agam, and Padang city districts.  The damage was not only caused by the earthquake itself but also due to the landsliding following the earthquake, such as in Tandikek.   Hundreds of people, houses, buildings, schools, as well as agricultural land (ricefield and dryland farming) were burried in Lubuk Laweh, Kepala Koto and Cumanak.  This research was conducted by employing survey method and by observing the phenomenon of tuff pumice on how it was affected by earthquake and water.  Then, soil characteristics were analysed based on soil physical data from previous research.  Several soil characteristics analysed were soil texture, bulk density, structure and depth of solum, organic matter content, and permeability.  Land characteristics were determined through field visit.  Some land condition being observed was slope (percentage and length), stone exposed, soil water depth, and land use.  Additionally, besides from field visit, the data were also obtained from topography and morphology maps derived from Google Earth.  Rainfall data (monthly and annually) were collected from several nearby meteorology stations.  Analyses for degree of landsliding risks for an area were used soil and land characteristics criteria causing landsliding.  Based on field visit, it was seen that the research area was still susceptible to landsliding.  This was due to the parent materials of the soil deriving from tuff pumice which is crumb structure and loamy texture on the top layer.  Climate, especially annual rainfall in study site was high enough (approximately 4322 mm) which was evently distributed all year long without dry month.    Slope of the area was > 45%, especially areas hit by landsliding.  Land use was not based on soil conservation rule, such as coconut and arenga pinneca, and other mixed trees were planted on the area having > 45% slope.  The results of the soil characteristic analyses  showed that HARKAT interval of lansliding threat was 13 and land characteristics showed 20.  Summation of HARKAT values from soil and land characteristics was 33.  This number showed that the study site had high degree of landsliding risk.  The possibility of areas would be hit by lansliding were Partamuan, Koto Timur,  Sungai Geringging, and around Maninjau lake.Keywords : earthquake, soil and land characteristics, tuff pumice, wet tropical
