Density - Nitrogen Ratio
• Learn about the latest trends and information on corn crop management with this training camp.
• Recommendations of optimal sowing and fertilization density. Everything to achieve the best performance.
Block 4. Density and use of nitrogen: the most used is urea, but does this complement the needs of our plant How many kilos of fertilizer (ammonium sulfate, urea, nitroperfect, nitromag, etc.) to use per hectare? What is the optimal density of each of the hybrids? find the sweet spot so that the yield is the most profitable and leaves more money to the farmers.
The optimum stocking density in all crops should be oriented to:
Avoid very low densities that limit the yield potential per unit area. The low populations cause considerable losses of humidity in the soil and favor the development of weeds.
Avoid very high densities that imply significant drops in the growth rate of the plants and, as a consequence, in yield. Plants tend to compete more in growth, sunlight capture, penetration and expansion of their root system, thus increasing lodging problems. Since the growth rate of the plants does not only depend on the planting density, its management should inevitably consider the environmental conditions that the crop could experience during its vegetative cycle (characteristics of the soil, water, climate, etc.) and other variables of crop management.
the selection of the density can determine an important part of the result of the culture. The correct choice must be based on a precise characterization of the environment and be linked to other crop management decisions (mainly sowing date and hybrid). Additionally, the selection of the density must consider aspects of the producer and his aversion to risk. Finally, it is important to consider that the sowing conditions (sowing and seed quality) and emergency (temperature and humidity) must be met to achieve the desired density objectives.
The balanced and efficient management of fertilization in corn nutrition is essential to obtain high and sustained yields that lead to a high profitability of the crop.
