In arid and semi-arid regions, water-saving irrigation is the primary mode of local agricultural production. Since the chemical fertilizer is the principal source of nitrous oxide (N2O) emissions, we present results from a two-year (2016–2017) field experiment on a potato field to verify the general influence of water-saving irrigation on N2O emissions. A split-plot experiment was established with two irrigation systems and two fertilizer treatments, which give a total of four treatments. Two different irrigation systems were investigated: (i) flood irrigation with nitrogen fertilizer (NF-FI)

SUMMARY Biological N2 fixation represents the major source of N input in agricultural soils including those in arid regions. The major N2-fixing systems are the symbiotic systems, which can play a significant role in improving the fertility and productivity of low-N soils. The Rhizobium-legume symbioses have received most attention and have been examined extensively. The behavior of some N2-fixing systems under severe environmental conditions such as salt stress, drought stress, acidity, alkalinity, nutrient deficiency, fertilizers, heavy metals, and pesticides is reviewed. These major stress

Lower nitrogen use efficiency (NUE) is a major yield limiting factor in semi-arid regions due to poor organic contents of the soils. There is a close relationship between soil organic matter and NUE of fertilizers. Therefore, this study was conducted to assess the effect of sole N fertilizer and its combinations with organic amendments (farm manure combinations) on N use efficiency and crop productivity. For this purpose, a two-year field study was conducted to access the influence of integrated use of synthetic N fertilizer (urea) and farm manure on N use efficiency and wheat productivity. Tr

Data from a long-term trial on rates of fertilizer nitrogen (N) application to maize (Zea mays) were used to validate a cropping systems simulation model (APSIM) and then to apply the model to explore the risk associated with N fertilizer use by smallholder farmers and management strategies to minimize that risk. On average, maize growth and development in response to N was simulated with a degree of accuracy that justified its use in analysis of risk associated with N use in these semi-arid regions of Zimbabwe. APSIM was then configured to simulate the response to N over a 46-year climate rec

AbstractCoupled aquaponics is the archetype form of aquaponics. The technical complexity increases with the scale of production and required water treatment, e.g. filtration, UV light for microbial control, automatic controlled feeding, computerization and biosecurity. Upscaling is realized through multiunit systems that allow staggered fish production, parallel cultivation of different plants and application of several hydroponic subsystems. The main task of coupled aquaponics is the purification of aquaculture process water through integration of plants which add economic benefits when selecting suitable species like herbs, medicinal plants or ornamentals. Thus, coupled aquaponics with closed water recirculation systems has a particular role to fulfil.Under fully closed recirculation of nutrient enriched water, the symbiotic community of fish, plants and bacteria can result in higher yields compared with stand-alone fish production and/or plant cultivation. Fish and plant choices are highly diverse and only limited by water quality parameters, strongly influenced by fish feed, the plant cultivation area and component ratios that are often not ideal. Carps, tilapia and catfish are most commonly used, though more sensitive fish species and crayfish have been applied. Polyponics and additional fertilizers are methods to improve plant quality in the case of growth deficiencies, boosting plant production and increasing total yield.The main advantages of coupled aquaponics are in the most efficient use of resources such as feed for nutrient input, phosphorous, water and energy as well as in an increase of fish welfare. The multivariate system design approach allows coupled aquaponics to be installed in all geographic regions, from the high latitudes to arid and desert regions, with specific adaptation to the local environmental conditions. This chapter provides an overview of the historical development, general system design, upscaling, saline and brackish water systems, fish and plant choices as well as management issues of coupled aquaponics especially in Europe.

This chapter focuses on controls and patterns of soil moisture in the Jornada Basin. First we describe general properties that commonly contribute to soil water heterogeneity; second, we offer a brief overview of soil water research in the Jornada Basin; and last, we describe specific patterns of soil water content and availability observed in the Jornada Basin. Our goal is to describe general patterns of soil water that are likely to occur across the Chihuahuan Desert region. In arid and semiarid regions, water is typically thought to be the most limiting resource to biological activity (Noy-Meir 1973), though colimitation by water and nitrogen may be a more general rule (Hooper and Johnson 1999; see also chapter 6). The availability of water affects plant productivity, microbial activity, activity of biological soil crusts, nutrient cycling, and organic matter decomposition. It also directly and indirectly affects soil erosion, chemical weathering, and carbonate formation. There are several hypotheses addressing how water availability affects plant productivity in desert environments. Beatley (1974) proposed that various functional types (e.g., shrub, perennial grass, annual forb) have different seasonal rainfall thresholds to trigger phenological responses. The annual productivity of functional types is therefore determined by the timing and amount of rainfall. Westoby (Noy-Meir 1973) proposed the pulse-reserve paradigm to explain population dynamics of desert plants. In this view, a rain event triggers a pulse of production. Some of that production is used to generate new tissue, but part of the production is diverted into reserves. The amount of reserves in part determines the next production pulse, as well as the minimum size of the next trigger event. Rainfall is highly variable both spatially and temporally in arid regions; therefore, understanding patterns of rainfall and interactions between rainfall patterns, soil characteristics, temperature, and topography are critical to predicting ecosystem responses. The relationship between average annual precipitation and plant productivity across arid regions has substantial predictive ability (Le Houérou 1984). However, for a given site, the relationship between annual precipitation and yearly plant productivity has limited explanatory power (Lauenroth and Sala 1992).

A soil is acidic if the pH value of the soil solution is less than 7.0. This condition is met in many soils where rainfall exceeds evapotranspiration, including Alfisols, Histosols, Inceptisols, Oxisols, Spodosols, and Ultisols—almost half of the ice-free land area worldwide. Soils of the humid tropics offer examples of acidic soils (Ultisols and Oxisols), as do soils of forested regions in the temperate zones of Earth (Alfisols, Histosols, Inceptisols, and Spodosols). Soils in peat-producing wetlands and those influenced strongly by oxidation reactions, such as rice-producing uplands, can be mentioned as examples in which the biota play a direct role in acidification. The phenomena that produce a given proton concentration in the soil solution to render it acidic are complex and interrelated. Those pertaining to sources and sinks for protons are shown in Fig. 11.1, which is a special case of Fig. 1.4 with “free cation or anion” in the center of the latter figure now interpreted as H+. In addition to the biogeochemical determinants of soil acidity, the field-scale transport processes wetfall (rain, snow, throughfall), dryfall (deposited solid particles), and interflow (lateral movement of soil water beneath the land surface down hill slopes) carry protons into a soil solution from external sources. Their existence and that of proton-exporting processes, such as volatilization and erosion, underscore the fact that the soil solution is an open natural water system subject to anthropogenic inputs that may dominate the development of soil acidity. Industrial effluents, such as sulfur and nitrogen oxide gases or mining waste waters, that produce acidic deposition or infiltration, and nitrog-enous fertilizers, the transformation and transport of which produce acidic soil conditions, are examples of anthropogenic inputs. Despite all this complexity, proton cycling in acidic soils at field scales has been quantified well enough to allow some general conclusions to be drawn. Acidic deposition, production of CO2(g) and humus, plus proton biocycling, all serve to increase soil solution acidity, whereas proton adsorption and mineral weathering serve to decrease it.

It naturally adapts to the adverse environments of extreme heat and water scarcity and prevents further desertification in addition to producing fruits with high nutritional value. It is seen in many parts of the world that traditional cultivation practices such as mixed planting and chemical fertilizers have led to low fruit quality resulting in low market values. Long generation time also hinders production of the dates. Tissue culture is therefore considered the most promising sol
