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 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...

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...

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...

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...

How to tell real phosphate fertilizer from fake? Here are a few practical methods
1. The role of phosphorus: the swelling element (the main nutrient for swelling of crop roots, stems, leaves and fruits), the energy of cell division. Deficiency symptoms: the most direct manifestation is uneven crop sizes in the field, especially obvious in orchards, and now most field crops also show this, with individual plants showing...
