Why can't the crops grow well even though a lot of fertilizer has been used?
This is the confusion of many farmer friends!
In fact, the problem may lie in the utilization rate of fertilizers - after traditional chemical fertilizers are applied to the soil, nitrogen fertilizers are prone to volatilization and loss, while phosphorus and potassium fertilizers are often trapped in the soil. How can we extend the fertilizer's effectiveness while unlocking soil nutrients?
Learn to utilize potassium fulvate from mineral sources. It is known as a slow-release agent for nitrogen fertilizers and an absorbent for phosphorus and potassium fertilizers. Today, let's lift the veil on its mystery.
How to use it scientifically? Remember these four points
1. Base fertilizer/top dressing: Mix with compound fertilizer and organic fertilizer, apply 1-2 kilograms per mu, reduce the loss of nitrogen, phosphorus and potassium, and prolong the fertilizer effect
2. Foliar spraying: Dilute 800 to 1000 times and spray during the seedling stage and flowering and fruit setting stage of crops to promote rapid absorption of phosphorus and potassium.
3. Pay attention to mixed use: Avoid mixing with strongly acidic (such as zinc sulfate) or strongly alkaline (such as Bordeaux mixture) fertilizers and pesticides. The best effect is achieved when the pH value is between 5 and 8.
4. Long-term use: Soil and root care are more important. Potassium fulvate from mineral sources is not only a fertilizer enhancer but also a soil conditioner. Long-term use can reduce soil compaction, lower salt content and make the land more fertile as it is cultivated. Especially in plots with severe continuous cropping obstacles and soil acidification and salinization, when used in combination with organic fertilizers, the effect is immediate.
