Tarımda Su Kıtlığına Yenilikçi Çözüm :’Hidrojeller’

Öz

Günümüzde iklim değişikliğinin çok yönlü etkileri, artan gıda talebi ve nüfus artışı su tüketimini ciddi ölçüde arttırmakta, su kaynaklarının kontrolsüz şekilde azalması ise günümüz dünyasının önemli sorunlarından biri olan su kıtlığına sebep olmaktadır. Yüksek miktarda su tutabilme/salabilme, tekrar kullanılabilme, zararsız ve ekonomik olma gibi özellikleri nedeniyle hidrojellerin kullanılması su kıtlığını önlemek için son derece yenilikçi bir çözümdür. Hidrojellerin tarımsal uygulamalarda doğru ve bilinçli kullanımı; (i) tarımda su ve toprak verimliliğinin arttırılmasını (ii) doğal çevrenin güvenliğinin sağlanmasını ve arazi erozyonunun önlemesini (iii) kurak bölgelerde bitki gelişiminin ıslah edilmesini ve (iv) tarım kimyasallarının kontrollü ve etkili kullanılabilmesini sağlamaktadır. Bu derleme makalede, hidrojellerin tarımsal uygulamalarda sağladığı avantajlardan, hidrojellerin su tutma mekanizmasından ve bu konuda önceden yapılmış çalışmalardan kısaca bahsedilecektir.

Innovative Solution to Water Scarcity in Agriculture: 'Hydrogels'

Öz

Nowadays, the multifaceted effects of climate change, increasing food demand, and population growth significantly increase water consumption, and the uncontrolled decrease in water resources causes water scarcity, which is one of the important problems of today's world. The use of hydrogels is a highly innovative solution to prevent water shortages, due to their high water retention/release, reusability, and being harmless and economic. The accurate and conscious use of hydrogels in agricultural applications. (i) increases water and soil productivity in agriculture (ii) ensures the safety of the natural environment and prevents land erosion (iii) improves plant growth in arid regions and (iv) enables the use of agricultural chemicals controlled and effectively. In this review article, the advantages of hydrogels in agricultural applications, the water retention mechanism of hydrogels, and previous studies on this subject will be mentioned briefly.
