Vegetable Wastes NPK Contribution Partially Inaccurate
“(NPK). Vegetable wastes primarily contribute nitrogenous compounds and potassium, supporting chlorophyll synthesis and vegetative growth, while animal-derived wastes supply calcium, phosphorus, and slow-release organic nitrogen through collagen and protein degradation.”
Summary
Vegetable wastes supply nitrogen, phosphorus, and potassium, not only nitrogenous compounds and potassium as claimed. Animal‑derived wastes do indeed provide calcium, phosphorus, and slow‑release organic nitrogen from collagen and protein degradation, so that portion of the statement is correct.

N is one of the essential elements which play a significant role in agriculture growth and development. N plays an important role in metabolic activities, vegetative growth, fruit quality, and yield (Chen et al., 2017; Liu et al., 2018). The N application on plant growth and development primarily manifests through alterations in biomass.

Compost can be applied more evenly and with better control than manure. The nitrogen in compost is not as readily available to plants as the nitrogen in fresh manure, but the availability of phosphorus, potassium and other nutrients from compost is similar to, or higher than, the availability of those nutrients from fresh manure.

The age of the natural fertilizers is another important factor. When natural material decays and is rained on, it loses nutrients, especially potassium and, to some extent, nitrogen.
