The Benefits of Deep Fertilizer Application and the Correct Application Methods
In recent years, production practice has proven that deep fertilizer application is a technical measure for improving fertilizer efficiency, reducing costs and increasing yields. I. Main forms of deep fertilizer application technology 1.1 Deep application of base fertilizer Use a fertilizing and soil-preparation machine, or add a fertilizer box and fertilizer-discharging device to a moldboard plow or paddy field tillage machine, so that while turning the soil it applies...

Reasonable Application Methods for Water-Soluble Fertilizers
Plants need to absorb various nutrients for growth and development. However, what determines crop yield is the nutrient factor present in the smallest relative amount in the soil, and yield also changes relatively within a certain limit as this factor increases or decreases. This is usually explained using a water-filled wooden bucket. The bucket is made of staves representing different nutrient contents and factors...

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...

Correct Application Methods for Water-Soluble Fertilizers
Water-soluble fertilizer (WSF) is a multi-element compound fertilizer that dissolves completely in water. It dissolves rapidly in water, is more easily absorbed by crops, and has a relatively high absorption and utilization rate. More importantly, it can be applied in facility agriculture such as spraying and drip irrigation, achieving...

How can phosphate fertilizer efficiency in wheat fields be improved? Practical methods shared
1. Apply after mixed composting and fermentation with organic fertilizer. Organic fertilizer is rich in organic matter, phosphoric acid and a variety of organic weak acids, which can turn insoluble phosphorus into soluble phosphorus. It not only greatly improves the utilization rate of phosphate fertilizer, but also effectively overcomes the problem of phosphate fertilizer burning seedlings. 2. Apply in combination with nitrogen fertilizer, potassium fertilizer, and zinc fertilizer...

Correct Methods and Techniques for Spraying Foliar Fertilizer on Fruit Trees
Spraying Period and Dosage 1. Nitrogen fertilizer should generally be used in the early and late stages of fruit tree growth, appropriately combined with phosphorus and potassium fertilizers. An appropriate spraying concentration can effectively promote new shoot growth, increase fruit yield, and benefit flower bud differentiation. The concentration for urea is 0.2-0.3% in the early stage and 0.3-0.5% in the late stage; for decomposed human manure...

How to choose foliar fertilizer for strawberries? Master these methods and key points
Strawberry is a herbaceous plant that thrives in warm and humid environments. In recent years, greenhouse strawberry cultivation has developed in various regions, yielding considerable profits. As the national strawberry market has improved, the national strawberry planting trend in 2006 reached a historic high. Faced with overwhelming foliar fertilizer advertisements, strawberry growers are at a loss...

Foliar fertilizer spraying methods for vegetables vary by variety
Leafy vegetables such as Chinese cabbage, spinach, shepherd's purse, etc. need more nitrogen, so the fertilizer sprayed should mainly be urea and ammonium sulfate, with a urea spraying concentration of 1%-2% and ammonium sulfate of 1.5%, sprayed 2-4 times per season, preferably during the early growth stage. Fruiting vegetables such as chili peppers, eggplants, tomatoes, green beans and various melons have a...

How do you judge whether phosphate fertilizer is good or bad? Here are a few practical identification methods
Topdressing with foliar fertilizer is one of the most commonly used, economical and fast-acting fertilization methods in vegetable cultivation. It involves mixing fertilizer into an aqueous solution of a certain concentration and spraying it directly onto crop leaves to make up for the insufficient nutrient supply caused by the weak nutrient uptake capacity of the roots. Extensive application has shown that topdressing with foliar fertilizer can improve vegetable yield and quality,...
