Questioni also am doing a project on whether commercial fertilizer will make a plant grow bigger than cow manure would. which one do you think would make a plant grow bigger
AnswerIt depends on your Soil. Cow Manure, in modest doses, would definitely yield the best results if you have a healthy sample of Soil. Commercial Fertilizer tends to induce deficiencies. But remember: No plant will ever grow bigger than its DNA pre-determines. People tend to forget that.
Good luck on your project, Charlie.
