What is the best time to apply manure to a field for optimal plant growth?

The best time to apply manure to a field is before planting. This is because the manure will have sufficient time to break down and incorporate into the soil, providing essential nutrients to the plants when they need them the most. Applying manure during planting or after planting may cause root damage and result in poor plant growth. Additionally, applying manure during fruit-forming stage may lead to excessive vegetative growth and delay the fruiting process. Therefore, it is important to apply manure before planting and ensure proper soil incorporation for optimal plant growth.
