INTERNATIONAL SOIL SCIENCE SYMPOSIUM on SOIL SCIENCE & PLANT NUTRITION, Samsun, Türkiye, 2 - 03 Aralık 2023, ss.254-258, (Tam Metin Bildiri)
Sustainable agriculture emerges as a system that protects the environment
and natural agricultural resources, has lower production costs and higher net
returns. As the basic principles of sustainable agriculture in the world,
minimum amount of agricultural chemicals should be used in order to protect
the environment and increase productivity. The use of different chemicals to
increase crop productivity may have adverse effects on ecosystems. Due to the
rapid increase in human population, the demand for nutrition needs continues
increase in food production. However, biotic and abiotic stresses caused by
pests and climate change significantly reduce crop productivity in agriculture.
Silicon can act as an anti-stress agent and play a protective role against abiotic
and biotic environmental stresses. Silicon can provide economic and ecological
benefits in plant growing. Silicon is also an advantage for sustainable
agriculture, as it is the second most abundant element in the world. Extractable
forms of Si in soil include amorphous, active and water-soluble silicon element.
Plants generally can uptake Si as the forms of orthosilicic (H4SiO4) or silicic
acid (Si(OH)4) through their roots. The availability of Si by the plant depends
on the humidity, temperature, pH and the accompanying ions in the
adsorption-desorption process of silicon in the soil. Especially in recent years,
soil and foliar Si treatments have been made against Si deficiency in plants. In
this review, the importance and applications of silicon for agriculture are
emphasized.
