Nitrogen is essential for healthy plant growth and good yield. Straight nitrogen fertilizers are often the major source of this important nutrient.
Fertigation" is the combined application of water and nutrients to a crop – a mix of fertilizer and irrigation. It can be adapted to all types of crops, but is most common in cash-crop segments, rather than broad-acre or arable crops.
Foliar applications are used for targeted input at key growth stages. By spraying directly onto the crop, nutrient availability can be controlled and soil interaction avoided.
