Dataset for Paper: Cellulose Acetate Microbeads for Controlled Delivery of Essential Micronutrients

The use of biodegradable materials to control the delivery of micronutrients to soil and plants has been explored, as it is an essential element in increasing agricultural yields. In this work, we developed a novel and efficient way to prepare biodegradable cellulose acetate beads containing zinc for use as controlled release fertilizers. Experimental work covered includes particle sizing, SEM imagery and ICP-OES to determine zinc release rates from beads.

Data in this dataset will include excel files, 3D models, and imagery.
