Spring is a very important period for farmers. While some crops are only preparing for sowing, others are already entering the phase of active growth. However, it is during this time that crops often fall into the “trap” of unstable weather conditions. Cold soil, sharp temperature fluctuations, and excessive phosphorus nutrition create ideal conditions for the occurrence of hidden deficiency. One of the most important micronutrients during this period is zinc.
Zinc is the main driver of metabolism and the “architect” of the plant’s hormonal system, as it is responsible for the synthesis of auxin (a growth hormone). Without auxin, a plant simply cannot grow in height, develop a strong root system, or form a future yield.
In spring, several factors affect zinc availability, even if there is enough of it in the soil:
Low soil temperature. At temperatures below 10–12°C, the root system functions extremely slowly. The diffusion of zinc ions to the roots almost does not occur.
Antagonism of phosphorus and zinc. The desire of farmers to give crops a strong start through high rates of phosphorus fertilizers often plays a bad joke: excess phosphorus blocks zinc uptake by forming insoluble compounds.
pH level. In alkaline soils (pH > 7), zinc becomes practically unavailable. A similar situation is observed in very light, sandy soils due to its leaching.
Symptoms that can cost you up to a third of your yield
The main danger of zinc deficiency is that it often occurs in a hidden form. When visual symptoms become noticeable, irreversible yield losses may already reach up to a quarter of the total harvest. The plant enters a state of “energy stagnation” due to metabolic disruptions.
What to look for in the field:
- Corn (4–6 leaves): The appearance of wide white or light-yellow stripes on both sides of the central leaf vein and shortened internodes are characteristic signs of zinc deficiency. As is well known, this is the period when the number of rows in the ear is formed, which significantly affects future yield.
- Sunflower: Even with perfect emergence, some plants begin to lag behind in growth; leaves become small, often narrower than usual, with wavy edges or deformed blades. Due to disrupted auxin synthesis, internodes shorten. Leaves begin to grow from a single point, forming a rosette. The plant appears “pressed” to the ground.
- Cereal crops: Reduced tillering and a change in leaf color to light green or yellowish (bronze). Longitudinal stripes appear on the leaves which, unlike in corn, may be dotted; leaves become brittle and may break at the most affected areas. The most dangerous issue is poor tillering — plants cannot form the required number of productive shoots. Later, this leads to poor grain filling in the ear.
- Fruit trees: Zinc deficiency is especially pronounced, as it paralyzes growth processes; leaves at the ends of shoots cluster into dense bunches, becoming small and rigid. The tissue between veins turns light green or yellow, while the veins and a narrow strip of tissue along them remain bright green, creating a “marbling” effect.
Rapid support and strategic protection
When roots cannot absorb zinc from cold soil, the only solution is foliar feeding. This is a direct “injection” of zinc into the plant’s metabolic system. However, not all zinc fertilizers are equally effective. For rapid recovery of metabolism, it is recommended to use professional chelated complexes such as MAKOSH Zn 8.
Why MAKOSH Zn 8? The product is designed for rapid elimination of zinc deficiency and activation of all related metabolic processes in the plant. The effectiveness of MAKOSH Zn 8 is based on a balanced composition:
- 8% zinc in chelated form ensures maximum availability.
- 2.5% amino acids and 8% organic acids ensure fast and efficient penetration of zinc into the cell.
- 5% nitrogen and 10% sulfur activate internal enzymes and ensure optimal plant growth and development.
Conclusion: Work proactively, not reactively
Zinc deficiency in spring is not just a temporary growth delay, but a serious blow to the financial outcome of the season. The peculiarity of this micronutrient is that its deficiency at early stages programs the plant for low productivity, which cannot be fully compensated by later fertilization.
Remember: the cost of preventive foliar feeding is minimal compared to the value of lost yield. Do not wait for visible symptoms when losses become obvious. Provide your crops with a reliable “zinc foundation” now to get the maximum from each plant at harvest.
