Benefits, Implementation Methods and Technical Points of Soil Testing and Formulated Fertilization for Crops
For crop growth, when the soil nutrients are insufficient, artificial fertilization is indispensable. So what is soil testing and formulated fertilization? How is it carried out? What benefits does it have? What techniques are involved? It is reported that soil testing and formulated fertilization is based on soil testing and fertilizer field trials, and according to crop nutrient requirements, soil nutrient supply capacity and fertilizer effects, on the basis of rational application of organic fertilizers, it proposes the application amounts, application periods and application methods of nitrogen, phosphorus, potassium and medium and trace element fertilizers.

Strawberry Cultivation: Experience Sharing on Soil Testing and Formula Fertilization
1. Fertilizer requirements: Strawberry growth requires nitrogen, phosphorus, potassium, and various trace elements such as boron, magnesium, zinc, iron, and calcium. Early growth requires phosphorus, the early-to-mid stage requires large amounts of nitrogen, and the entire growth period requires potassium. With severe nitrogen deficiency, the leaves turn yellow, become partially scorched, and are slightly smaller than normal leaves.

How to apply formula fertilization to hybrid watermelons
Hybrid watermelons require high water and high fertilizer. According to calculations, producing 1000 kg of watermelons requires 5 kg of N, 2 kg of P2O5, and 5 kg of K2O. If hybrid watermelons are planted on medium-fertility soil with a yield of 3000 kg per mu, then 15 kg of N, 6 kg of P2O5, and 15 kg of K2O are required. When fertilizing, achieve

How is soil testing and formulated fertilization carried out for rice cultivation?
I. Technology Introduction Based on the fertilizer requirement characteristics of major crops and formulated fertilization technology, soil testing and formulated fertilization mainly follows three principles: first, combining organic fertilizer with inorganic fertilizer; second, combining macro, secondary and trace elements; third, combining land use with land maintenance, with input and output in balance.

Key Technical Points for Soil Testing and Formulated Fertilization in Sweet Potato Cultivation
1. Fertilizer requirements: Of the three major elements nitrogen, phosphorus and potassium, sweet potato has the greatest demand for potassium, followed by nitrogen, then phosphorus. Sweet potato likes potassium, and increasing potassium fertilizer has a clear effect on both yield and quality. Sweet potato absorbs few nutrients at the seedling stage; from the branching and tuber-setting stage to the vigorous stem and leaf growth

How to choose fertilizer varieties for formula fertilization of winter wheat
According to many years of production practice over large areas, applying formula fertilizer for winter wheat once as base fertilizer (all base and topdressing applied in one go) is an economical and efficient fertilization method. Such wheat fields generally show strong but not excessive wheat seedlings, well-developed root systems, thick and sturdy stems, strong disease resistance, large spikes with many grains

How to do soil testing and formulated fertilization for tea planting
In tea fertilization, our province commonly has problems such as insufficient organic fertilizer use and an unreasonable ratio of nitrogen, phosphorus and potassium application. Soil testing and formulated fertilization for tea should, on the basis of adhering to the combination of organic and inorganic fertilizers, control the total amount of nitrogen fertilizer, especially control the amount of nitrogen fertilizer applied later, improve

Key Technical Points of Soil Testing and Formula Fertilization for Rice
Based on the technical principles of soil testing and formula fertilization, and combined with the actual work of soil testing and formula fertilization in Pulandian City, 10 technical steps in the experimental process of soil testing and formula fertilization for rice were summarized. 1. Site selection: Select locally representative plots, and arrange experimental plots according to the areas of high-, medium-, and low-fertility farmland. The fertility status of the experimental site should be uniform and consistent, and the fertilization status of the previous crop should be as similar as possible. 2. Soil sampling and testing: Collect soil samples before plowing, using a "plum blossom shape" or "snake shape" to take 15-20 points, with a vertical depth of
