What methods are there to improve fertilizer use efficiency?
1. Fertilizer application rate. The application rate of compound fertilizer is based on the amount of nitrogen. Compound fertilizers contain multiple nutrients and mostly belong to the nitrogen, phosphorus and potassium three-element type. Except for special fertilizers for legume crops, which are mainly phosphorus and potassium fertilizers, all take nitrogen as the main nutrient, and in the nutrient ratio nitrogen is always dominant, matched with corresponding phosphorus and potassium nutrients. For one...

How to tell real fertilizer from fake? Keep these methods in mind
As the saying goes: "Fool the land for a moment, and the land fools you for a year." Once farmers buy and use fake or inferior chemical fertilizers, the losses caused are hard to make up for, which both dampens farmers' enthusiasm and harms farmers' interests. Below are the common methods for identifying real and fake fertilizers: Visual inspection First look at the fertilizer packaging. The fertilizer packaging bag must indicate the product name, nutrient content (grade), trademark, net weight, standard code, factory name and address, contact phone number, production license number and fertilizer registration number, etc. If the above markings are absent or incomplete and the packaging is rather rough, it may be fake or inferior compound fertilizer. Pay special attention to fertilizers whose packaging bag seals show obvious signs of being opened; this phenomenon may indicate adulteration. In addition, pay attention to the production date on the production certificate inside the fertilizer bag. If fertilizer is stored for too long, the total nutrients will be lost. Second, look at the fertilizer's granule size (or crystalline state). High-quality fertilizer has relatively uniform granule size and specific gravity, a smooth surface, and is not prone to absorbing moisture or caking, while fake and inferior fertilizer is exactly the opposite, with uneven granule sizes, a rough surface, high moisture, and easy caking. Third, look at the fertilizer's color. High-quality fertilizer has very uniform color, with no obvious color difference, and the entire granule is uniform from the inside out. Most fake fertilizer, however, is colored on the surface and easily loses its color.

Application Methods and Technical Key Points of High-Efficiency Organic Fertilizer
I. How to Apply High-Efficiency Organic Fertilizer to Vegetables 1. Application Rate: According to the nutrient requirements of various vegetable crops, apply 60-100 kg per mu as base fertilizer for each crop of vegetables. Baosheng High-Efficiency Organic Fertilizer is mild in nature, and applying more is unlikely to cause fertilizer burn; for vegetables, melons and fruits with high economic value or high yield, the application rate may be increased by 20-50%. Baosheng...

Key Technical Points and Detailed Methods of Foliar Fertilization
Do not spray in extremely hot weather or before rain, so as to avoid burning the seedlings or losing fertilizer nutrients. The best time to spray is in the early morning or afternoon each day, and after spraying, wait 7-10 days before spraying again. When spraying on cereal crops or crops with smooth leaves, add 0.1% adhesive (such as laundry detergent or dish soap), etc. Otherwise, the effect...
