*Diatomaceous Earth (DE) - is an all natural source of plant available silica and trace elements. DE is a naturally occurring silica sediment that improves plant defences and reduces drought and heat stress. Silica (Si) is taken up and deposited in plant tissue, enhancing the plant's ability to deal with both biological and environmental stresses. It improves structural strength for reducing lodging and pest attack and is used for its natural insect repelling properties. It also improves photosynthetic activity and utilisation of fertilisers.
