Although Brazil is one of the world's leading exporter agricultural products, country highly dependent on importation potassic fertilizers. K-bearing silicate rocks are reported as potential solutions to reduce external K dependency. This work evaluated extraction from Verdete rock, a glauconite-bearing rock containing 10 % K2O, by solubilization with organic acids. Firstly, was reacted during ...

Abstract Wheat productivity is severely hampered by drought, owing to its negative impacts on crop growth and development. For obtaining better yield, the of drought should be ameliorated. Therefore, current study scrutinizes potential different silicon (Si) forms minify drought-associated reduction in yield changes nutrients accumulation. In a strip plots design based randomized complete block...

Purpose. The problem of heavy metal Cd pollution in the soil is still very serious. widely used treatment measure situ passivation chemical remediation technology. Some studies have shown that single application phosphate or silicate can control cadmium pollution, but few been conducted on effect thermal activation temperature nano and silicate-combined transformation form soil. Materials metho...

In this paper, the influence of water glass types, modulus glass, alkali content, consumption, and plant fibers on mechanical strengths alkali-activated blast furnace slag powder (BFS) is investigated. Moreover, fiber types pretreatment measuring temperature performance BFS are further considered. Results indicate that activated by potassium silicate shows higher than sodium silicate. The with ...

Some researchers report that one potential tool for reducing fungicide requirements on turfgrasses may be the use of silicon (Si) fertilizers. Silicon has been reported to suppress diseases on various crops in the last decade (Raid et al., 1992; Cherif et al., 1994; Deren et al, 1994; Seebold et al, 2000; Seebold et al., 2001). Researchers in North Carolina found that brown patch and dollar spo...
