Choose a balanced fertilizer with an appropriate NPK ratio, such as a general-purpose, slow-release granular fertilizer with equal NPK ratios. When preparing the planting hole for seedlings, mix a small amount of balanced fertilizer into the soil to provide a nutrient-rich environment.
Seaweed. This product is kelp that is ecologically harvested, dried and ground into a powder. It comes to you in either powder or liquid concentrate. Mixed with water, it can be used alone or with fish emulsion as a foliar spray or soil drench. This is the “black gold” of organic fertilizers.
Among the synthetic nitrogen fertilizers produced from anhydrous ammonia, urea has been leading the fertilizer market in world agriculture since the 1960s, which can be attributed to the nonhazardous properties of an organic compound that can easily be applied to the soil or mixed with other fertilizers to prepare NPK formulations.
Commercial fertilizers for Okra NPK ratio . Different NPK ratios are available for Okra fertilizers. The most common is the 10-10-10 ratio, which means that fertilizer has 10% nitrogen (N), 10% phosphorate (p), and 10% potassium (K). When choosing the NP ratio for your Okra fertilizer, be sure to consider the needs of the plant.
The results showed that both fertilizers influenced the maize rhizosphere microbial community but the organic amendments provided the most stable microbial community; these results were also found by Zhang et al. , in which higher levels of NPK treatments (60 kg of NPK fertilizer as N/ha) negatively affected the microbial community structure
