Figure 3From: Controlled root targeted delivery of fertilizer using an ionically crosslinked carboxymethyl cellulose hydrogel matrix The effect of loading dose and RTDV synthesis condition on the growth of wheat plants. The plants were either supplied with 20-20-20 fertilizer daily as a positive control (“red horizontal line”) or RTDVs at the start of the experiments. The RTDVs were loaded with 20-20-20 fertilizer: 22% dose, 24 h drying (“blue triangle symbol” RTDV 4), 44% dose, 24 h drying (“pink triangle symbol” RTDV 9), 44% dose, heating during cross-linking (“green triangle sysmbol” RTDV 10). Plant height (mean ± S.D., n = 3) is reported.Back to article page
