Signs That Your Crops Need More Nitrogen Now
Nitrogen is a necessary element for healthy plant growth; fertilizers typically contain a mix of nitrogen, potassium, and phosphorus, but nitrogen is so necessary that you will often find high-nitrogen fertilizers available for plants that are low in just that specific element. Nitrogen is readily available — thank goodness — but you do want to be sure that your plants are actually low in nitrogen and not another element. You don't want to waste money and fertilizer while not helping your plants.
