Article develops recommendations for the use of reducing (incentive) coefficients in land tax calculation of on agricultural lands, taking into account the quality of land and interrelation between an increase and decrease in soil fertility, which leads to an increase in land tax. In calculating land taxation, this is formed based on the normative value of agricultural land. The calculation of the normative value of agricultural land is inextricably linked with the soil quality index (SQI), which determines the fertility of the soil. As decreasing and increasing coefficients in the growth of productivity in 11 agriultural farms of “Pakhtaobod” massif of Nishan adiminstrative district of Kashkadarya province, when the normative value changed for the better, the amount of land tax decreased by 18.933.000 UZS (19.5%) and in 10 agriсultural farms the increase in the amount of land tax by 7.070.820 UZS (15.8%) in the negative condition.

The objective of this work was to construct a simple index based on the presence/absence of different groups of soil macrofauna to determine the ecological quality of soils. The index was tested with data from 20 sites in South and Central Tabasco, Mexico, and a positive relation between the model and the field observations was detected. The index showed that diverse agroforestry systems had the highest soil quality index (1.00), and monocrops without trees, such as pineapple, showed the lowest soil quality index (0.08). Further research is required to improve this model for natural systems that have very low earthworm biomass (<10 g m-2) and a high number of earthworm species (5-7), as it is in the tropical rain forest, whose soil quality index was medium (0.5). The application of this index will require an illustrated guide for its users. Further studies are required in order to test the use of this index by farmers.

Soil Quality Assessment

Assessment of the soil natural fertility is important in the socio-economic stability and development of each territory. Purpose: This study is devoted to the method of solving an important socio-economic problem – determining the soil fertility index. Research methodology. In the course of the research the methods of the theory of soil quality assessment, mathematical statistics, field and laboratory researches of the numerical values forming the estimated cost of soils are used. Natural soil fertility is represented by the five most important groups of factors: morphological, physical, agrochemical, physicochemical and environmental. Each group of factors may include a number of individual indicators that researchers believe are the most influential in assessing this type of soil. Soil quality is a complex natural functional system that cannot be obtained from direct measurements, but can be determined with a certain degree of confidence by processing the values that most fully characterize the soil. In this regard, a number of methods and methodological approaches to their definition have been developed. To this end, we have chosen a five-point rating scale, which makes it possible to assess each factor in a single evaluation system. The scientific novelty. Based on known methods of soil quality assessment, the authors propose a methodological approach that allows not only to assess the determination of the soil quality index and its accuracy but also the influence of individual factors on the index value. Results: classification of the factors forming the soil quality index, their scores` assessment and methodology of database processing have been developed, and their practical application and confirmation have been found in experimental studies. Practical significance. This can be used by experts in the field of soil assessment to develop proposals and recommendations for public authorities and local governments to address land administration issues.

Physiochemical parameters of soil under Shorearobusta forest was estimated to evaluate the soil fertility status and soil quality index in different altitudes of community managed forest of Khairani Municipality Chitwan district Nepal. Altogether 75 soil samples were collected from the forest area at five different depths. Sandy clay loam and sandy loam texture was found in surface and subsurface layer respectively. The mean soil pH of altitudinal strata was 5.57 which is moderately acidic and showed decreasing trend with increasing soil depths. Average bulk density ranged from 1.14 to 1.30 in all attitudes. Organic carbon varied from 0.30 to 1.30% and organic matter ranges from 0.52 to 2.23%. The amount of mean available phosphorus seem low to medium rating in these forest strata. Mean exchangeable potassium varied from 61.89 mg kg-1 to 96.02 mg kg-1 in different altitudes. Most of these soil attributes decreased with the increasing depth. Pearson correlation analysis among the different soil parameters were showed statistically significant at the 0.01 level (2 – tailed) and 0.05 levels (2 - tailed).One way ANOVA of the studied soil parameters in different altitudes observed that they were statistically significant at 0.05 level (p ≤ 0.05). The overall soil fertility status of the Kankali Community Forest is low to medium. An average SQI was found 0.55 (fair) up to 120 cm depths,slightly decreased with increasing soil depths. Regulation of Leaf litter collection and adoption of appropriate silvicultural operation may help to increase the fertility status and site quality of Kankali community forest.

Abstract. Assessment of soil quality is one of the key parameters for evaluation of environmental contamination in the mining ecosystem. To investigate the effect of coal mining on soil quality, opencast and underground mining sites were selected in the Raniganj Coafield area, India. The physical, chemical, biological parameters, heavy metals, and PAHs contents of the soils were evaluated. Soil dehydrogenase (+79%) and fluorescein (+32%) activities were significantly higher in underground mine (UGM) soil, whereas peroxidase activity (+57%) was higher in opencast mine (OCM) soil. Content of As, Be, Co, Cr, Cu, Mn, Ni, and Pb was significantly higher in OCM soil, whereas, Cd was higher in UGM. In general, the PAHs contents were higher in UGM soils probably due to the natural coal burning in these sites. The observed values for the above properties were converted into a unit less score (0–1.00) and the scores were integrated into environmental soil quality index (ESQI). In the unscreened index (ESQI-1) all the soil parameters were included and the results showed that the quality of the soil was better for UGM (0.539) than the OCM (0.511) soils. Principal component analysis was employed to derive ESQI-2 and accordingly, total PAHs, loss on ignition, bulk density, Be, Co, Cr, Ni, Pb, and microbial quotient (respiration: microbial biomass ratio) were found to be the most critical properties. The ESQI-2 was also higher for soils near UGM (+10.1%). The proposed ESQI may be employed to monitor soil quality changes due to anthropogenic interventions.

Purpose. The aim of the article is the development of scientifically substantiated proposals on state stimulation of the process of investment of farms of the corporate sector of the agrarian economy in increasing the fertility of agricultural lands in the conditions of transformation processes of land relations. Methodology of research. In conducting the study, its methodological and theoretical basis is the dialectical method of cognition and a systematic approach to the study of the fundamental provisions of economics for investment activities in the agricultural sector of Ukraine. A set of special methods of economic research was used in the research process. The conclusions of the research are formulated with the help of abstract and logical method. The method of theoretical generalization was used in the critical analysis of the results of research by domestic scientists on the substantiation of economic incentives to increase the fertility of agricultural land. Results. The economic levers of the state regulation of nature use in the production of agricultural products are substantiated, which provides for the use of a comprehensive combination of payments for the rational use of agricultural land and penalties for reducing soil fertility. Originality. A scientific approach to the reproduction of land resources in agricultural enterprises is proposed, which is based on a set of organizational and economic tools for socially responsible activities, in particular: development of programs for targeted use of agricultural land and providing them with appropriate funding, calculation of land tax and other changes in soil quality, which will increase the fertility of agricultural land. Practical value. The implementation of the proposed economic stimulus measures will help increase the rational land use of agricultural producers and improve soil quality. The use of the proposed measures is possible only with a well-established system of agrochemical assessment of agricultural land. Key words: fertility, capital investments, agricultural lands, state, agricultural commodity producers.

Data Variability

The Bajío—Mexico’s central lowlands—is a region of economic importance because of its agricultural industry. Over time, agricultural practices have led to soil deterioration, loss of fertility, and abandonment. In this study, six agricultural soils were analyzed: AGQ, CTH, CTJ, JRM, CRC, and CYI, and used to develop a soil quality index (SQI) that includes the use of physicochemical, biological, and ecophysiological indicators to differentiate soil quality. Principal component analysis (PCA) was used, reducing the indicators from 46 to 4, which represents 80.4% of data variability. It was implemented the equation of additive weights using the variance of the principal components as a weight factor for the SQI. The developed SQI was according to the indicators WHC, SLT, N-NO3−, and qCO2, differentiating the quality of soils from the agricultural management in low quality (JRM < CYI < AGQ) and moderate quality (CTJ < CRC < CTH). The use of biological and ecophysiological indicators added to the PCA and the equation of additive weights allowed establishing an SQI with a minimum of indicators, sensitive to agricultural management, facilitating its interpretation and implementation for the Mexican Bajío region and soils in similar conditions around the world.

This paper presents a new approach to assess the soil quality by aggregate indices using the Relative Soil Quality Index (RSQI) proposed by Ho Ngoc Pham. RSQI is integrated from the individual indices into a simple formula for overall assessment of the soil quality. RSQI is different from other approaches. Particularly, the individual indices and the weighting factors of Pham are calculated from the analytical laboratory data and the environmental standards, respectively, and not self-regulated as in methods of some other authors. In this paper, the authors applied the RSQI to assess the Soil Environmental Quality of rice intensive cultivation areas through a case study in Haiduong province in 2013. The RSQI is calculated for sampling points in 12 districts and simulated the Soil Environmental Quality on GIS map. The results show that the Soil Environmental Quality of rice intensive cultivation areas in Haiduong is predominantly divided into three levels: good, moderate, and poor. According to the report of General Statistics Office for Haiduong province, rice intensive cultivation areas in 2013 achieved a relatively high average rice yield of 5.90 tonnes per hectare; it means actual soil properties are in line with results of the research.
