Pineapples grown in acid soils containing high levels of manganese (Mn) can exhibit iron deficiency because Mn interferes with iron bio-functioning. This situation is commonly corrected with regular iron sprays. Soil Mn concentration can be reduced by liming, but pineapple growers keep the soil pH below 5.0 because it helps reduce the incidence of rots caused by Phytophthora sp. This study was ...
Calcium (Ca)-loaded biochar was produced from rice husks by loading the Ca source with subsequent carbonization and examined evaluation of P adsorption capability about method, availability oyster shells as alternative, effect temperature. Ca-loaded prepared at 650°C had CaCO3 form, that 400°C unconverted Ca(OH)2 less CO2 generation. Moreover, silicon in might have existed an amorphous structur...
Background & Aims: Numerous studies showed that vitamin D has direct effect on the innate and acquired immune system. Serum levels of vitamin D play an important role in the incidence of infectious disease and also the outcome of its treatment. Materials & Methods: In this observational and cross-sectional study, the serum levels of vitamin D, calcium, and, PTH in 44 patients with different ...
This research was aimed at investigating the effects of foliar application of calcium silicate and sodium silicate on growth and biochemical characteristics and leaf elements of chrysanthemum. This study was conducted as a factorial with completely randomized design and silica source at two levels (calcium silicate and sodium silicate) and concentration of silica at five levels (0 (control), 50...
