  • Applying organic fertilizer to vegetables has its rules; more is not always better

    Traditional agriculture holds that vegetable fields should be given large amounts of organic fertilizer, and some even believe that the more organic fertilizer, the better. But according to the results of many trials in various places in recent years, appropriately increasing the application of organic fertilizer can effectively control excessive nitrate in vegetables, while blindly increasing organic fertilizer will cause excessive nitrate in vegetables. The nitrate contained in vegetables...

  • What effect does applying organic fertilizer to corn have on its growth

    Manure, green manure, and decomposed straw can all be called organic fertilizer. Organic fertilizer is rich in organic matter and various nutrients, and is the most complete natural compound fertilizer in terms of nutrients. It can not only directly provide nutrients to crops, but can also activate potential nutrients in the soil and increase the content of available nutrients in the soil. Organic fertilizer...

  • Why is it not advisable to apply too much organic fertilizer to vegetables?

    Traditional agriculture holds that vegetable fields should be heavily fertilized with organic fertilizer, and some vegetable growers even believe that the more organic fertilizer, the better. However, according to the results of many experiments carried out in various places in recent years, appropriately increasing the application of organic fertilizer can effectively control the nitrate content of vegetables, while blindly increasing the application of organic fertilizer will cause the nitrate content of vegetables to exceed the standard. Vegetable nitrate...

  • How to apply fertilizer scientifically in hot and dry weather

    It is not advisable to apply large amounts of undecomposed cake fertilizer. Cake fertilizer has a relatively small carbon-to-nitrogen ratio and decomposes quickly, easily generating high temperatures. Applying undecomposed cake fertilizer will raise the local temperature, cause root burn and affect seed germination, and will also attract underground pests. The cake fertilizer should be crushed and soaked in human urine until it heats up before application. Compound fertilizer cannot be used alone...

  • Methods and Key Technical Points for Applying Phosphate Fertilizer in Orchards

    In spring and summer, the periods before and after flowering of fruit trees are stages prone to various diseases (physiological diseases and pathogen toxin diseases). At this stage, in addition to necessary chemical prevention, timely application of phosphorus and potassium fertilizers is also a good choice. However, many fruit growers tend to apply only nitrogen fertilizers (such as urea, high-nitrogen...

  • How to apply insecticides scientifically? Correct methods and techniques

    To control crop pests with pesticides and achieve the best insecticidal effect, in addition to selecting the right targeted agent and applying it at the right time, you should also pay special attention to the following two issues that are easily overlooked. Different agents and different application methods should be chosen according to the part of the plant the pest damages, so that the pesticide is delivered to the right place. For example, for pests that damage...

  • Apply phosphate fertilizer this way, and crops will resist drought and increase income

    Crops absorb phosphorus fastest during the seedling stage, and the seedling stage is also the critical period for phosphorus nutrition. If phosphorus is deficient during the seedling stage, it will affect the later growth of the crop. In our province, spring temperatures are low, soil microbial activity is weak, and the release of soil available phosphorus is low. In addition, low soil temperature weakens the root system's ability to absorb nutrients, making it difficult to meet the crop's needs during the critical period of phosphorus nutrition. ...

  • What are the precautions for applying diammonium phosphate?

    Phosphorus promotes soybean root growth and is beneficial for the formation of root nodules. When the supply of phosphorus in the soil is insufficient, although soybean rhizobia can invade the roots, they do not form nodules. Molybdenum fertilizer is an essential trace element for nitrogen fixation in root nodules, and when the soil is deficient in phosphorus, applying molybdenum fertilizer alone actually reduces the number of root nodules. Phosphorus's effect on the amino... in root nodules

  • How to apply foliar fertilizer to grapevines? These techniques must be mastered

    Spraying grapevines with foliar fertilizer gives the leaves a wide fertilizer-receiving surface, acts quickly, saves labor and fertilizer, and is a commonly used fertilization method for grapes. Generally, absorption begins 2 hours after the fertilizer solution is sprayed, and 88% of a urea solution can be absorbed within 24 hours after spraying. Spraying 0.2%-0.3% urea solution mixed with 0.1% boric acid or borax or multi-element boron fertilizer during the flowering period can...

  • Methods and Techniques for Scientifically Applying Phosphate Fertilizer to Wheat

    Wheat is a crop with a relatively high phosphorus requirement, and scientifically applying phosphate fertilizer is one of the key measures to improve phosphate fertilizer efficiency, reduce fertilization costs, and promote high-quality and high-yield wheat. 1. Apply after mixing and composting with organic fertilizer. Organic fertilizer is rich in organic matter, phosphoric acid, and various organic weak acids, which can turn insoluble phosphorus into soluble phosphorus...
