“…[ 56 ]. For example, a portion of Ca is absorbed on the hyphae’s surface in the form of calcium oxalate (CaOx) crystals [ 57 ]. The formation of CaOx was significantly increased by the presence of bicarbonates released by calcite and nitrates from fertilization [ 58 ].…”

Granular Calcite Stimulates Natural Mycorrhization and Growth of White Spruce Seedlings in Peat-Based Substrates in Forest Nursery

The acidity of peat-based substrates used in forest nurseries limits seedling mineral nutrition and growth as well as the activity of microorganisms. To our knowledge, no study has yet evaluated the use of granular calcite as a covering material to increase pH, calcium and CO2 concentrations in the rhizosphere and ectomycorrhizal development. The objective is to compare different covering treatments on early colonization of the roots by ectomycorrhizal fungi, as well as the growth and calcium nutrition of white spruce seedlings in the forest nursery. Three treatments were used to cover the plant cavities (Silica (29 g/cavity; control treatment), Calcite (24 g/cavity) and calcite+ (31 g/cavity)) and were distributed randomly inside each of the five complete blocks of the experimental design. The results show that calcite stimulates natural mycorrhization. Seedlings grown with calcite have significant gains for several growth and physiological variables, and that the periphery of their root plugs are more colonized by the extramatrical phase of ectomycorrhizal fungi, thus improving root-plug cohesion. The authors discuss the operational scope of the results in relation to the tolerance of seedlings to environmental stress and the improvement of their quality, both in the nursery and in reforestation sites.

Although lime is currently the most commonly applied material for soil acidity correction in Brazil, calciummagnesium silicate application may efficiently replace this source due to its higher solubility and silicon supply, which is beneficial for plant development. This study aimed to evaluate the efficiency of surface liming and silicate application on soil chemical attributes as well as soybean and maize nutrition, yield components, and grain yield. The experiment was conducted in a Rhodic Hapludox in Botucatu-SP, Brazil. The randomized complete block design contained 16 replications. Treatments consisted of two materials for soil acidity correction (dolomitic lime, calcium/magnesium silicate), applied on October 2006 to raise base saturation up to 70%, and a control, with no acidity correction. Soybean and maize were sown in 2006/2007 and 2007/2008, respectively. After 18 months Ca-Mg silicate corrected soil acidity up to 0.60 m, and increased exchangeable base levels up to 0.40 m. Silicate increased silicon concentrations in plant tissues in both crops as well as phosphorus in soybean. The application of both sources increased calcium and magnesium concentrations as well as yield components and yield grains of soybean and maize. Soil acidity correction improved the efficiency of fertilizers applied for grain production.Keywords: acid soils, Brazilian 'Cerrado', liming, annual crops 363 Surface application of limestone and calcium-magnesium silicate in a tropical no-tillage system

“…Calcium carbonate (CaCO 3 ) is a major component of calcareous soils, which cover up to 13% of the Earth's land surface (Summerfield 1991), and corrections of low pH by liming are common amendments for acid soils (Monfort-Salvador et al 2015). The CaCO 3 content in calcareous soils varies from a few percent to 95% (Marschner 1995).…”

This study aimed to determine the capacity of monosilicic acid [Si(OH) 4 ] to mitigate nutritional and metabolic disorders in plants induced by high levels of soil calcium carbonate (CaCO 3), which raises soil pH and lowers solubility of soil micronutrients. Plants (Cucumis sativus L.) were grown in a soil with increasing rates of Si(OH) 4 at two CaCO 3 doses. Biometrical parameters, leaf chlorophyll and leaf and stem nutrients as well as leaf metabolic responses, using a metabolomics approach, were evaluated. Additionally, extractable Si and Si plant availability were examined. Manifestations of Si-induced effects in cucumber were highly CaCO 3-dependent. In the-CaCO 3 plants, Si(OH) 4 addition induced distinct plant-beneficial effects, such as enhanced transport of iron (Fe) and manganese (Mn) to stems and/or leaves, accompanied with enhanced leaf abundance of metabolites (αtocopherol, galactinol, threonic and ferulic acids) potentially involved in plant defence mechanisms against diverse environmental stresses. Biostimulant activity of Si(OH) 4 was not evident in plants grown in the CaCO 3-treated soil, characterized by reduced extractability and bioavailability of Si, compared with the untreated soils. The low physiological effectiveness of Si(OH) 4 on the CaCO 3-treated soil is likely due to a significant decrease in plant availability of Si, against a background of drastic plant performance impairment at high pH values induced by CaCO 3 excess.
