Soil Conditioners: Boosting Soil Health and Farmer Productivity

Healthy soil is the foundation of productive farming. For farmers, ensuring that their land is fertile, nutrient-rich, and capable of sustaining crops is paramount. One of the most effective ways to achieve this is through the use of soil conditioners. Soil conditioners are substances added to soil to improve its

## Top dressing for healthier, high-yield maize: a practical guide for farmers Maize farming remains one of the most important agricultural activities for farmers across Kenya and the region. Whether grown for food or income, maize performance depends heavily on proper nutrition throughout the growth cycle. Many farmers focus a lot on planting fertilizer but underestimate what happens next. In reality, the stage after establishment, especially top dressing, is where yield potential is either built or lost. Top dressing is the practice of applying fertilizer after the maize crop has already emerged and established. This second feeding supports rapid vegetative growth, strong stalk development, and proper cob formation. When done correctly, top dressing can make a very clear difference in crop uniformity, plant strength, and final harvest. --- ## Why top dressing is critical in maize farming At planting, maize is usually supplied with a starter fertilizer such as DAP PLUS or another phosphorus-rich blend. This helps with early root development and seedling vigor. However, as maize grows, its nutrient demand increases sharply, especially for nitrogen. Nitrogen is responsible for leaf growth, chlorophyll formation, and overall plant energy. Without enough nitrogen during the vegetative stage, maize turns pale, grows slowly, and produces smaller cobs. Top dressing ensures that maize does not run out of nitrogen at the most demanding growth stage. In addition to nitrogen, calcium plays an important supporting role. Calcium strengthens plant cell walls, improves nutrient movement within the plant, and supports strong stalk formation. This is especially important in high-yield fields where heavy cobs can easily cause lodging if stalks are weak. --- ## When to top dress maize Timing is everything when it comes to top dressing. The most effective time to top dress maize is when the crop reaches knee height, also known as the V6–V8 growth stage. This usually occurs about four to six weeks after planting, depending on rainfall, soil fertility, and temperature. At this stage, the maize plant has developed enough roots to efficiently absorb nutrients, and the demand for nitrogen is very high. Applying fertilizer too early leads to losses, while applying too late limits cob development and final yield. A simple field guide is this: when maize reaches your knee and has strong green leaves, it is ready for top dressing. --- ## Which fertilizer to use for top dressing For maize top dressing, nitrogen is the key nutrient. While many farmers traditionally use urea, SeedPro recommends using **CalciTopper 26:0:0** as a more balanced and efficient option. CalciTopper 26:0:0 contains **26 percent nitrogen** together with **calcium**, making it ideal for maize at the top-dressing stage. The nitrogen drives rapid leaf growth and photosynthesis, while calcium strengthens plant tissues, supports nutrient uptake, and helps the crop stand firm until harvest. Unlike urea, which is highly prone to nitrogen losses through volatilization especially under hot and dry conditions, CalciTopper is more stable in the soil. This means more of the applied nitrogen is actually used by the maize crop rather than being lost to the atmosphere. CalciTopper is particularly useful in areas with acidic soils, weak stalk problems, or where farmers aim for higher yields and better crop uniformity. --- ## Recommended rates for CalciTopper 26:0:0 The amount of fertilizer to apply depends on soil fertility, previous fertilizer use, and expected yield. However, a practical guideline for most maize fields is as follows: If maize was planted using **DAP PLUS or another phosphorus-based starter**, apply **CalciTopper 26:0:0 at knee height**. Recommended application rate: * **150–200 kg per hectare of CalciTopper 26:0:0** * This is equivalent to approximately **60–80 kg per acre** Fields that are vigorous and well managed can use the lower rate, while weaker fields or high-production systems can benefit from the higher rate. Always ensure even application across the field to avoid uneven crop growth. --- ## Best practices for applying CalciTopper To get the best results from top dressing, proper application is just as important as choosing the right fertilizer. Apply CalciTopper when the soil has moisture or just before expected rainfall. Moisture helps dissolve the fertilizer and move nutrients into the root zone. Avoid applying during extreme dry conditions or just before heavy storms that can wash nutrients away. Broadcast the fertilizer evenly along the rows, keeping it a short distance from the plant base to avoid scorching young roots. Light incorporation with a hoe or timely rainfall will further improve nutrient availability. Consistent spacing, correct plant population, and good weed control will allow the maize to fully benefit from the applied nutrients. --- ## Combining top dressing with foliar feeds While top dressing supplies the main nutrients, foliar feeds can be used later to correct specific deficiencies or boost performance during tasseling and grain filling. Foliar nutrition should support, not replace, soil-applied fertilizers. Using CalciTopper as the main top dressing ensures the crop has a strong nutritional foundation, while foliar feeds can fine-tune performance when needed. --- ## Common mistakes to avoid during top dressing One common mistake is delaying top dressing until maize starts showing severe yellowing. By then, yield loss has already begun. Another mistake is uneven application, which leads to patchy growth and uneven cob sizes. Over-application should also be avoided. Too much nitrogen can result in excessive leafy growth at the expense of grain filling and may increase lodging risk. ## Final thoughts Successful maize farming is not just about planting and waiting for rain. It is about timely decisions, correct nutrition, and using the right products at the right stage. By starting with a strong planting fertilizer like DAP PLUS and following up with **CalciTopper 26:0:0 at knee height**, farmers can support healthy growth, strong stalks, and well-filled cobs. This balanced approach to maize nutrition leads to more consistent yields and better returns at harvest.18 December 2025
