The main objective of this study is to evaluate suitability of shrink-swell soils for surface irrigation system based upon a parametric evaluation system in low irrigation potential (7%) of cotton growing Yavatmal district, Maharashtra, India. The thirty three shrink-swell soil series on basaltic landforms were identified from reconnaissance soil survey on 1:50,000 scale and evaluated for surface irrigation methods using Geographic Information System (GIS). The standard weekwise rainfall data showed that the rainfall is less than 20% of total precipitation during September and December, the top A horizon reaches to wilting point and needs supplementary protective irrigation to cotton based cropping systems . It was estimated that ten soil mapping units (1.8 Mha and 13.89%) of shrink-swell soils on moderate slopes (5 to 8%) were evaluated as suitable for surface methods and calculated the irrigation intervals that vary from 8.61±1.35 days for cotton to 8.9±1.4 days for wheat and 10±1.64 days for sugar cane. The study emphasized the utility of soil resource maps helps to delineate the soils with large PAWC(>200mm) with slight yield advantage and will serve as benchmark sites to monitor the interrelationships of soil water dynamics with respect to climate and cotton yields.

Hau Giang is one of 13 provinces in the Mekong Delta. Total land area is 162,171 ha (statistics 2014), agricultural land is 141,217 ha accounting for 87.08 % of natural area. To exploit the reasonable land and provide a scientific basis for adjusting the land use planning to 2020, the evaluation of land resources in Hau Giang was carried out. To apply the land evaluation methodology of FAO to research on natural conditions, socio-economic related to land use to evaluate land resources as well as to apply for geographic information system (GIS) and automatically land evaluation system (ALES) gave results positively, quickly and efficiently. Evaluation results showed that Hau Giang had four major land groups with 11 land mapping units; alluvium land group accounted for 37.26 % of natural area. From the map overlay has been integrated 28 land units. Basing on 44 LUTs surveys was selected for 16 LUTs to have development prospects to evaluate land suitability. Land use was divided into 5 main groups: alluvial land belonged to riverside Hau, slightly saline land was not submerged and was shallow, and low-lying saline land was flooded and saline land was salty. To combine with evaluating the current state of land use, productive techniques and socio-economic development needed supplementing of land use planning by 2020 as follows: (1) agricultural land is 141,217 ha (87.08 %); (2) non-agricultural land is 20,918 ha (12.90 %) and (3) unused land is 36 ha             (0.02 %) of natural area.

In this study, a fuzzy logic system was used to optimise a parametric evaluation system in surface and sprinkler irrigation systems. This study was performed on a surface area of 5,175 ha in the Fath-Ali region located in the Ardabil province of Iran. It was indicated that for the sprinkler and surface irrigation system, an area of about 385.06 ha (7.4%) and 159.81 ha (3%) of land is “highly suitable” and an area of about 286.1 ha (5.5%) and 312.69 ha (6%) is “moderately suitable”, respectively. About 2,810.08 ha (54.3%) and 2,744.17 ha (53.02%) were respectively “marginally suitable” for the sprinkler and surface irrigation systems. The “currently not suitable” suitability included about 1,322.88 ha (25.5%) and 1,746.05 ha (33.7%) and the “permanently not suitable” suitability included about 370.91 ha (7.1%) and 212.28 ha (4.1%) in the zone under study. According to the results, there is a major difference between the “highly suitable” land obtained through the two methods and the area of the “highly suitable” land using the sprinkler irrigation method is about two times the area of the “highly suitable” obtained through the surface irrigation method.

Ethnopedological studies have mainly focused on agricultural land uses and associated practices. Nevertheless, peasant and indigenous populations use soil and land resources for a number of additional purposes, including pottery. In the present study, we describe and analyze folk knowledge related to the use of soils in non-industrial pottery making by peasant potters, in the municipality of Altinho, Pernambuco State, semiarid region at Brazil. Ethnoscientific techniques were used to record local knowledge, with an emphasis on describing the soil materials recognized by the potters, the properties they used to identify those soil materials, and the criteria employed by them to differentiate and relate such materials. The potters recognized three categories of soil materials: “terra” (earth), “barro” (clay) and, “piçarro” (soft rock). The multi-layered arrangement of these materials within the soil profiles was similar to the arrangement of the soil horizon described by formal pedologists. “Barro vermelho” (red clay) was considered by potters as the principal ceramic resource. The potters followed morphological and utilitarian criteria in distinguishing the different soil materials. Soils from all of these sites were sodium-affected Alfisols and correspond to Typic Albaqualf and Typic Natraqualf in the Soil Taxonomy (Soil Survey Staff, 2010).

The article is devoted to substantiating the prospects for increasing the marginal volumes of agricultural production for export in the next four years. Two scenarios of such production are considered: 1) expansion and 2) intensification of the use of land resources. As part of the development of the first scenario, an analysis of the distribution of unused agricultural land, including arable land, by federal districts was carried out. Also, based on the forecast of the introduction of additional annual volumes of acreage in the subjects of the Federation, the calculation of additional volumes of agricultural production, which can be expected in the next four years, was carried out. The analysis of data on the increase in the yield of export-oriented crops over the past five years has been carried out, in the framework of the second scenario, the calculation of the projected additional yield due to the intensification of agriculture is presented. The results of the study indicate that the intensification of agriculture will have the greatest impact on the growth of production and export of agricultural products in the near future.

Historical surface irrigation of pastures in the Dutch province of Noord-Brabant: visible traces of a failed experiment In the second half of the 19th century, some major changes occurred in the water management of the eastern and southern provinces of the Netherlands. Unlike the low-lying western parts of the Netherlands which were characterised by polders and had a long history of formal water boards, the higher eastern and southern parts of the Netherlands were characterized by brook systems and sandy soils, and had no centralised water boards until 1850. From the 1850s onward, water boards were introduced in these higher regions as well, and agronomical scientists and organisations like the Nederlandse Heidemaatschappij endeavoured for the modernisation of agricultural water management. One of their priorities was the introduction of modern forms of surface irrigation of pastures, in order to increase crop yields. In various places modern irrigation systems were constructed. From the 1900s onward, these systems were abandoned due to the introduction of new chemical fertilizers, among others. This article describes the construction and abandonment of one of these modern irrigation systems that was located in Liempde, in the province of Noord-Brabant. The local farmers were not interested in the new technique, and within a few years the system was transformed in a poplar plantation. Nowadays, the area is part of a nature reserve. Nonetheless, the global layout of the irrigation system is still visible.

N Loading

The nitrogen (N) balance in a double-cropped, effluent spray irrigation system was examined for several years in southern Australia. The amounts of N added by irrigation, removed in the crop, and lost by ammonia (NH3) volatilisation, denitrification, and leaching were measured. Results from the project provide pig producers with the knowledge necessary to evaluate the efficiency of such systems for managing N, and enable sustainable effluent reuse practices to be developed. Oats were grown through the winter (May to November) without irrigation, and irrigated maize was grown during the summer/autumn (December to April). Approximately 18 mm of effluent was applied every 3 days. The effluent was alkaline (pH 8.3) and the average ammoniacal-N (NH4++ NH3) concentration was 430 mg N/l (range: 320 to 679 mg N/l). Mineral N in the 0- to 1.7-m layer tended to increase during the irrigation season and decrease during the winter/spring. About 2000 kg N/ha was found in the profile to a depth of 2 m in October 2000. N removed in the aboveground biomass (oats + maize) was 590 and 570 kg N/ha/year, equivalent to ≈25% of the applied N. Average NH3volatilisation during the daytime (6:00 to 19:00) was 2.74 kg N/ha, while volatilisation at night (19:00 to 6:00) was 0.4 kg N/ha, giving a total of 3.1 kg N/ha/day. This represents ≈12% of the N loading, assuming that these rates apply throughout the season. The balance of the N accumulated in the soil profile during the irrigation season, as 15N-labelled N studies confirmed. The high recovery of the15N-labelled N, and the comparable distribution of 15N and Br in the soil profile, implied that there was little loss of N by denitrification, even though the soil was wet enough for leaching of both tracers.

Agricultural land use planning should always be guided by a reliable tool to ensure effective decision making in the allocation of land use and activities. The primary aim of this study is to develop a user friendly system on a spatial basis for agricultural land suitability evaluation of four groups of agriculture commodities, including food crops, horticultural crops, perennial (plantation) crops, grazing, and tambak (fish ponds) to guide land use planning. The procedure used is as follows: (i) conducting soil survey based on generated land mapping units; (ii) developing soil database in GIS; and (iii) designing a user friendly system. The data bases of the study were derived from satellite imagery, digital topographic map, soil characteristics at reconnaissance scale, as well as climate data. Land suitability evaluation in this study uses the FAO method. The study produces a spatial based decision support tool called SUFIG-Wilkom that can give decision makers sets of information interactively for land use allocation purposes.This user friendly system is also amenable to various operations in a vector GIS, so that the system may accommodate possible additional assessment of other land use types.

Relevance. The effective use of agricultural land is a fundamental prerequisite for the successful implementation in the agro-industrial complex of the task of providing the population with food, and production with raw materials. At the same time, the issues of methodological support of the procedures for determining the integral indicator for assessing the use of agricultural land, established on the basis of a theoretically grounded unified approach based on quantitative methods, have been developed with insufficient completeness. Actualization of the issues of improving the theory and practice of assessing the effectiveness of the use of agricultural land in agricultural production is becoming one of the priority tasks of land reclamation science. The purpose of this work is to create a methodological basis for the process of assessing the use of agricultural land, which guarantees the comparability of the considered options for agroproduction in different natural and economic conditions.Methods. The research is based on the method of point assessments for indicators of agricultural land exploitation and the formation on their basis an integral criterion of land use efficiency. The proposed procedure includes: analysis of statistical data characterizing the dynamics of the values of indicators of used land resources, calculation of local assessments of the feasibility of their exploitation and assessment of the efficiency of land use according to a generalizing criterion represented by the sum of these local assessments.Results. A methodology has been developed and a method has been created for determining the efficiency of the use of agricultural land, based on a generalized integral assessment of the operation of agricultural land, which allows to identify bottlenecks in agricultural production and outline rational directions for the development of land use. The testing of the algorithm of the methodology and capabilities of the scale for the integral assessment of the efficiency of the use of land resources was carried out on the example of the Non-Black Earth Zone of the Russian Federation. Shown is an unsatisfactory (below the national average) contribution of agricultural production to the gross regional product. On the whole, positive dynamics of agricultural production in the Non-Black Earth Zone was established, which is achieved due to the development of animal husbandry, which is an effective factor in the formation of modern efficient agriculture of the territory, with the orientation of the crop production system on the raw material basis of feed production or the sector of the economy of the agro-industrial complex of the territory.
