Foliar feeding cannot be done at will; only by mastering the correct method can it be effective
Foliar topdressing of vegetables is a fertilization method in which fertilizer is dissolved in water and sprayed onto the leaf surface. This method is simple, convenient to apply, low in cost, quick in effect and high in benefit. It is especially suitable for topdressing trace elements and plays a positive role in increasing vegetable yield and quality, but it must be done scientifically and reasonably. 1. Fertilizer types...

Correct Methods and Technical Key Points for Foliar Fertilization of Vegetables
Spraying an aqueous solution of the nutrients plants need onto the leaves, so that plants directly absorb effective nutrients through their leaves, is a technique called foliar fertilization of vegetables. Compared with soil fertilization, this technique has the advantages of rapid conversion, high fertilizer use efficiency, and promotion of nutrient uptake by the root system. Foliar fertilizers can be broadly divided into macro...

What is the correct method for foliar feeding of fruit trees?
1. Types, timing and amounts of spray fertilizer. 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 spray 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; decomposed...

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...

Scientific application methods and technical key points for potash fertilizer
Potassium is one of the three essential fertilizer elements. Many vegetables often require more potassium than nitrogen and phosphorus; well-grown vegetables contain potassium at 2.5%-7% of their dry matter, higher than their nitrogen and phosphorus content. Most vegetables absorb more potassium than nitrogen; for example, the nitrogen-to-potassium ratio absorbed by cucumber is 1:(1.5-1.7), by pumpkin is 1:2.1, and by tomato is 1:...

Application Methods of Potassium Fertilizer in Vegetable Cultivation
There are many types of potassium fertilizer, and different types have different application methods. Commonly used potassium fertilizers include potassium chloride, potassium sulfate, potassium-magnesium fertilizer and plant ash. Potassium chloride and potassium sulfate are physiologically acidic fertilizers and should be applied together with lime and organic fertilizer. For chlorine-sensitive crops such as potatoes, potassium chloride and potassium-magnesium fertilizer with high chlorine content should not be applied...

How to tell good phosphate fertilizer from bad? A few practical methods
August to October is the suitable sowing period for autumn crops in the south, such as rapeseed, broad beans, green manure, potatoes and various autumn vegetables, all of which are sown during this period. Experienced farmers know that autumn crops emphasize the application of phosphate fertilizer; this is based on the causal relationship between crops, soil and fertilizer, and is determined by phosphate fertilizer itself...

How to identify organic fertilizer? A few practical methods to teach you
1 Water soaking method Take a cup, soak an organic fertilizer sample in water, then use your hand to crush the organic fertilizer soaked in the water, stir it a bit and you can intuitively see the raw materials of the organic fertilizer; then let it sit for a while, if the organic fertilizer and water separate within a short time, it means the organic fertilizer has a high specific gravity and contains more soil. 2 Smell method Carefully...

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...
