Soluble silicon compounds in soils of different granulometric composition of the western region of Ukraine

Abstract

Аbstract. One of the most common elements in the earth's crust is silicon. In soils, its content varies widely. One hundred years ago, to the role of silicon in agriculture and human nutri on was not paid a en on. But with the intensifica on of agricultural produc on in addi on to the basic elements, nitrogen, phosphorus, potassium, the importance of which for crop yields is recognized, much a en on was paid to secondary and trace elements, in par cular, silicon. The aim of the research was to determine the content of soluble silicon compounds in the arable layer of chernozem-type soils depending on their par cle size distribu on. The research was conducted on arable lands of Novoushitsky district of Khmelnytsky region. In soil samples were determined: par cle size distribu on and content of frac ons of different sizes according to SSTU 4730:2007; pH of salt extract according to SSTU ISO 10390:2001; humus content according to SSTU 4289:2004; the content of exchangeable compounds of calcium and magnesium by extrac on with 1.0 M KCl solu on. Silicon compounds in soils were determined by the method of Mullen and Riley with extrac on of silicon by the method of V.V.Ma chenkov. Studies that were conducted on agricultural soils of Khmelnytsky region have shown that the content of silicon compounds in soils is related to the par cle size distribu on of Ґрунтознавство та агрохімія

Spatial Heterogeneity of Soil Silicon in Ukrainian Phaozems and Chernozems

“…With the intensification of agricultural production, in addition to the basic elements, i.e. nitrogen, phosphorus, potassium, the importance of which for crop yields is recognized, much attention was paid to secondary and trace elements, in particular, silicon [Bykova et al, 2020]. In some regions, fertilizing the soil with the silicon-containing materials is becoming standard agricultural practice for growing rice, sugar cane, sugar beet.…”
