Only 20% of imported Japanese strawberries pass pesticide residue testing
The Consumers' Foundation sampled local and imported strawberries in January this year. Of the twelve strawberry samples tested, only the Korean strawberries had no pesticide residues detected; the remaining eleven strawberry samples were found to contain one to seventeen types of pesticide residues, and six of them did not meet the allowable agricultural residue limits, giving an overall failure rate of 50%. Broken down by place of origin, Japan's failure rate was even higher

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.

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 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
