I know too much nitrogen can burn plants. But, what about too much phosphorous? |
It's less of a problem because most people don't apply as much phosphorous as they do nitrogen and phosphorous doesn't move as readily through the soil as does nitrogen. But too much of any chemical fertilizer can burn plants. Organic fertilizer sources are less likely to burn since they have a lower concentration of nutrients and often need to break down further before plants are able to utilize them. Chemical fertilizers are immediately available for plant roots to uptake. |
