The low NUE observed for plants in agricultural soils is in part due to the nature of conventional fertilizers which, once applied, will release a large amount of nutrients in the early stage of plant growth, leaving too little at later stages. [] To overcome this issue, controlled release fertilizers (CRF) have been explored as an approach to deliver …

Nitrogen (N), phosphorus (P), and potassium (K) are the primary nutrients plants require, each serving a critical role in plant health. Organic options, while slower to take effect, improve long-term soil fertility. Synthetic choices offer immediate nutrient availability, which is beneficial for fast-growing or nutrient-deficient plants.
