To maximize the return on fertilizer investment and ensure minimal environmental damage, it is necessary to follow sound, research-backed guidelines.
To maximize returns from your fertilizer dollar, consider these four points:
- What nutrients are needed?
- How much of each nutrient is needed?
- What source of fertilizer should be used?
- How and when should they be applied?
The recommended time for nitrogen application is April 1-30, but it can be applied in May as well. Applying nitrogen fertilizer prior to April 1 has the potential for being lost to leaching and denitrification and can stimulate early weed growth.
A complete soil fertility program is essential for maximum sugarcane yields and profits. Use soil tests properly. Know the lime and fertilizer requirements for each field on which you grow sugarcane, and apply the plant nutrients according to the recommendations and soil test results. Avoid unproven and “miracle” products. Producers will harvest better yields and make more profit if they follow the recommendations.
