CULTAN Fertilization

According to a study from the Czech Republic, injecting nitrogen into the soil leads for a higher dry matter content of the plant.^[3] Dry matter content is important because the nutrients found in plants are found in the ‘dry’ section, not the water that is also in the plant. CULTAN fertilization, like all forms of injection fertilization, allows for a more precise application and a more uniform distribution of the fertilizer. These methods allow the spread of nitrogen regardless of the condition of the field (wet, muddy) and reduce soil compaction caused by tractors moving along the field. Soil compaction can eventually lead to erosion. Labor is also significantly reduced when compared to convention, surface fertilization.^[2]

Research has shown that average total yield is lower in crops that have been injected with nitrogen.^[3] The equipment used to inject fertilizer into the ground is more expensive than the typical spraying equipment, so injection is mostly used on smaller produce operations.
