Mineral Soils

Acid soils limit crop production on 30-40% of the world's arable land and up to 70% of the world's potentially arable land. Over 60% of the total arable lands in Serbia are acid soils. Soil acidity is determined by hydrogen (H+) in soil solution and it is influenced by edaphic, climatic, and biological factors. Major constraints for plant growth on acid mineral soils are toxic concentrations of mineral elements like Al of H+ and/or low mineral nutrient availability due to low solubility (e.g. P and Mo) or low reserves and impaired uptake (e.g. Mg2+) at high H+ concentrations. Aluminum (Al) toxicity is primary factor limiting crop production on acid soils. This review examines our current understanding of mechanisms of Al-toxicity, as well as the physiological and genetic basis for Al-toxicity and tolerance. Inhibition of root growth by Al leads to more shallow root systems, which may affect the capacity for mineral nutrient acquisition and increase the risk of drought stress. Of the two principal strategies (tolerance and avoidance) of plants for adaptation to adverse soil conditions, the strategy of avoidance is more common for adaptation to acid mineral soils. At the same, the short view of the most important genetics tolerance mechanisms, developed and determined in some small grains genotypes, is showed as well.

Soil acidity and aluminum toxicity are considered most damaging soil conditions affecting the growth of most crops. This paper reviews the results of tests of pH, exchangeable acidity and mobile aluminum (Al) concentration in profiles of pseudogley soils from Cacak-Kraljevo basin. For that purpose, 102 soil pits were dug in 2009 in several sites around Cacak- Kraljevo basin. The tests encompassed 54 field, 28 meadow, and 20 forest soil samples. Samples of soil in the disturbed state were taken from the Ah and Eg horizons (102 samples), from the B1tg horizon in 39 field, 24 meadow and 15 forest pits (a total of 78 samples) and from the B2tg horizon in 14 field, 11 meadow, and 4 forest pits (a total of 29 samples). Mean pH values (1M KCl) of the tested soil profiles were 4.28, 3.90 and 3.80 for the Ah, Eg and B1tg horizons, respectively. Soil pH of forest samples was lower than those in meadow and arable land samples (mean values of 4.06, 3.97 and 3.85 for arable land, meadow and forest samples, respectively). Soil acidification was especially intensive in deep horizons, as 27% (Ah), 77% (Eg) and 87% (B1tg) soil samples had the pH value below 4.0. Mean values of total exchangeable acidity (TEA) were 1.55, 2.33 and 3.40 meq 100 g-1 for the Ah, Eg and B1tg horizons, respectively. The TEA values in forest soils were considerably higher (3.39 meq 100 g-1) than those in arable soils and meadow soils (1.96 and 1.93, respectively). Mean mobile Al contents of tested soil samples were 11.02, 19.58 and 28.33 mg Al 100 g-1 for the Ah, Eg and B1tg horizons, respectively. According to the pH and TEA values, mobile Al was considerably higher in the forest soils (the mean value of 26.08 mg Al 100 g-1) than in the arable soils and meadow soils (the mean values of 16.85 and 16.00 mg Al 100 g-1, respectively). The Eg and B1tg horizons of the forest soil had especially high mobile Al contents (the mean values of 28.50 and 32.95 mg Al 100 g-1, respectively). High levels of mobile Al were especially frequent in the forest soils, with 35% (Ah), 85.0% (Eg) and 93.3% (B1tg) of the tested samples ranging above 10 mg Al 100 g-1.

Micronutrient Uptake

Crop production on acid soils can be improved greatly by adjusting the pH to near neutrality. Although soil acidity is commonly corrected by liming, there is evidence that animal manure amendments can increase the pH of acid soils. Fresh cattle manure and agricultural lime were compared for their effects on soil acidity and the production of canola (Brassica napus L.) and wheat (Triticum aestivum L.) in a greenhouse study. Canola and wheat yield, the nutrient content of grain and straw, and selected soil properties were determined on a Gray Luvisol (pH 4.8) from the Peace Region of Alberta. Soil pH increased with lime and manure applications, and canola and wheat yields were higher in limed and manure-amended soils than unfertilized, unlimed soils. Macronutrient uptake by canola and wheat was generally improved by liming and manure applications, and micronutrient uptake was related to the effects of lime and manure on soil pH. An economic analysis compared the costs of using cattle manure and lime to increase soil pH to 6.0. The costs of applying lime and fresh cattle manure to increase soil pH were compared, based on the fees for purchasing and applying lime or loading, hauling and applying manure. The nutrient value of manure was calculated based on the quantities of plant-available N, P and K in fresh manure. At distances less than 40 km, it is economical to substitute fresh cattle manure for agricultural lime to increase soil pH of acidic soils. However, good manure management practices should be followed to minimize the risk of nutrient transport and environmental pollution from agricultural land amended with cattle manure.

Aluminum Accumulation

Aluminum (Al) toxicity is a limiting factor for crop production in acid soils, which cover approximately 60% of the Brazilian territory. This study aimed to evaluate the effects of Al on growth and tissue Al concentration of two Pfaffia glomerata accessions (BRA and JB/UFSM). Plantlets were grown in a hydroponic system with five Al concentrations (0, 50, 100, 150 and 200mg L-1) for 7 days. Most of the evaluated parameters presented significant interaction between both P. glomerata accessions and Al levels in nutrient solution and, in general, Al treatments negatively affected plant growth, especially roots. Moreover, BRA accession showed higher Al accumulation in its tissues than JB/UFSM and, consequently in BRA accession the growth was impaired substantially. Furthermore, the results suggest that, between P. glomerata accessions studied, BRA is less appropriated for medicinal uses when grown in soils with high Al levels, due to the higher accumulation of tissue Al content.

Soil Quality Index

Arable lands are needed for sustainable agricultural systems to support an ever-growing human population. Soil quality needs to be defined to assure that new land brought into crop production is sustainable. To evaluate soil quality, a number of soil attributes will need to be measured, evaluated, and integrated into a soil-quality index using the multivariable indicator kriging (MVIK) procedure. This study was conducted to determine the spatial variability and correlation of indicator parameters on a field scale with respect to soil quality and suitability for use with MVIK. The variability of the biological parameters decreased in the order of respiration > enzyme assays and qCO2> microbial biomass C. The distribution frequency of all parameters except respiration were normal although the spatial distribution across the landscape was highly variable. The biological parameters showed little correlation with each other when all data points were considered; however, when grouped in smaller sections, the correlations were more consistent with observed patterns across the field. To accurately assess soil quality, and arable land use, consideration of spatial and temporal variability, soil conditions, and other controlling factors must be taken into account.

Major Factors

Soil acidity is one of the major factors limiting soil fertility and crop production in large areas of Ethiopia. A two-month incubation experiment was conducted to evaluate the effects of lime, vermicompost (VC), and chemical phosphorus (P) fertilizer on selected chemical properties of Dystric Nitisols in Ebantu District, Western Ethiopia. The treatments comprised of three rates of lime (2, 4, and 6 tons CaCO3·ha−1), VC (2.5, 5, and 7.5 tons·ha−1), and mineral P fertilizer (20, 40, and 60 kg·P·ha−1) each applied alone and in various combinations. The experiment was laid down in a completely randomized design with two replications. The results showed that the highest increment of pH from 4.83 at the control to 6.05 and reduction of exchangeable Al from 1.70 to 0.09 cmolc·kg−1 were obtained from combined application of lime at 4 tons CaCO3·ha−1 and VC at 7.5 tons·ha−1. The most significant decrease in exchangeable acidity (0.17 cmolc.kg-1) was observed in soil that was treated with 6 tons CaCO3·ha−1 lime applied alone (93%) and combined application of lime at 4 tons CaCO3·ha−1 with VC at 7.5 tons·ha−1 by (81%). The highest contents of OM (4.1%) and total nitrogen (0.29%) were obtained from combined application of lime at 4 tons CaCO3·ha−1 and VC at 7.5 tons·ha−1. Integrated application of chemical P (60 kg·P·ha−1) with lime (2 tons·ha−1) plus VC (7.5 tons·ha−1) resulted in Bray-II P increased by 45% relative to control. The various combinations of the treatments also improved exchangeable Ca2+ and Mg2+. The results indicate that integrated use of lime, vermicompost, and chemical P fertilizer can improve soil acidity and availability of nutrients. However, the real potential of the amendments used in this experiment should be further assessed under field conditions using a test crop.

The paper reveals the experimental results of long-term agroecological monitoring of agricultural land, conducted by Tomsk state agrochemical service, and experiments on designing the measures to improve efficiency of acidic arable land. In Tomsk region, 83% of arable land is acidic and the degree of acidity increases annually. Every 10 years weighted average pH is reduced on 0.1-0.2 units; the area of acidic soils increases. There is an urgent need for liming these soils in order to improve efficiency of agricultural production in Tomsk region. According to the calculations, the region requires 3,248 million tons of chalky flour. The region has its own large deposits of limestone, for example Kamenskoe (61 million tons), located 50 km from Tomsk, where it is possible to produce valuable meliorant, increasing efficiency of agricultural production. The authors make case, that for successful development of agricultural production in Tomsk region, it is necessary to design and implement long-term target program “Chalking of acid soils in Tomsk region”, which assumes compensation for agricultural producers for the part of the cost of liming; design and technical support of works; local production of limestone meliorants. Implementation of the acidic soil liming program will increase annual crop production in Tomsk region on 54.9 - 129.2 thousand tons of grain units, therefore it will increase annual income on 494.1 - 1162.8 million rubles (in 2017 prices), as well as ensure further increase in agricultural land fertility with high fertilizer efficiency, product quality and profitability.

AbstractThe purpose of this review was to show the importance of silicon (Si) in agricultural production. Si is a second most abundant element both on the surface of the earth and in the soil. Si in plants leads to an increase in horticulture production. It has been demonstrated to have multiple direct and indirect beneficial effects on growth and development of many plants. The beneficial effects of Si are especially pronounced in the plants exposed to abiotic and biotic stresses. Si enhances tolerance of plants to metal toxicity. Si uptake by plants improves agricultural crop quality and yield. Si application could therefore improve crop production under adverse climate and soil conditions. Si can positively influence plant growth and yield, in particular, under stress conditions. Si may increase the uptake and translocation of mineral elements in plants. The application of stabilised silicic acid is called the ‘silicic acid agro technology’ (SAAT). SAAT increases root system size, length of stem/tillers, leaf area, chlorophyll content and nutrient uptake, resulting in higher yield and improved. SAAT decreases effect of biotic and abiotic stresses. Therefore, SAAT is proposed as an element in sustainable cropping strategies.

Soil acidity is one of the forms of soil degradation affecting sustainable crop production adversely in the Ethiopian highlands. In order to contribute to soil acidity amelioration and crop productivity improvement on acid soils, an experiment was conducted to investigate the effects of lime, mineral P, FYM, compost, and rhizobium on growth, nodulation, and nutrient uptake of faba bean (Vicia faba L.) in cultivated acid soil under greenhouse conditions. Twenty treatments were tested in isolations as well as suitable combinations. The treatments were arranged in a completely randomized design with three replications. The results showed that application of 8 t FYM·ha−1 + 30 kg P·ha−1 + 5 t lime·ha−1 produced significantly (P<0.001) higher plant height (58.67 cm), number of branches (13.78) and leaves per plant (37.11), shoot dry weight (5.14 g per plant), tissue N (3.83%) and P (0.219) contents and uptakes, and soil N (0.28%) and P (7.61 mg·Kg−1) after harvest. However, significant increases (P<0.001) in nodule number (153.33) and nodule dry weight (131.33 mg per plant) were obtained due to application of 4 t FYM·ha−1 + 15 kg P·ha−1 + 10 t lime·ha−1. The increased above-ground biomass, and nodulation could be due reducing soil acidity, and the supply of N, P, and other nutrients in FYM through mineralization. Therefore, combined use of lime, FYM, and P fertilizers could improve the growth characteristics, nodulation, and nutrient uptake of faba bean in acid soil of Lay Gayint district. However, the treatments should be tested in the field to verify the greenhouse results.

Seven surface and eight subsurface acid soils, sampled from six Canadian provinces, were cropped to barley in a greenhouse experiment. The soils were limed at determined rates to produce the following soil conditions: I, soluble Al to 8 ppm; II, exchangeable Al to 2 meq/100 g soil; III, base saturation to 60%; and IV, full base saturation. The adjustments were not as precise as intended, but they did provide means for finding relations between soil acidity measurements and barley yield response to lime. Both a 5-day equilibration method and a rapid method for soil analysis showed that soluble Al and percent base saturation correlated better with barley yields than did exchangeable Al and pH. The 5-day equilibration method gave the better correlations, with soluble Al, percent base saturation, exchangeable Al and pH accounting for 68, 73, 40 and 39% of the variation in barley yields, respectively. Although this study indicated that soluble Al and percent base saturation gave equally good predictions of Al-sensitive crops to liming, the soluble Al measurement is simpler and, therefore, more suitable for general diagnostic purposes.
