Fertilizers are rich in nutrients and are beneficial to all types of crops. However, improper use can lead to poor results. Before applying fertilizers, it's important to conduct a soil test to determine the specific needs of the land. Based on the crop's nutrient requirements, a "consumption plan" should be developed to ensure proper application.
The main sources of fertilizer include ammonium and other compounds such as tetradecadecandundecane. These materials are particularly effective in slightly alkaline soils due to their acidic nature. When blending urea with other fertilizers, the ratios must be adjusted according to the type of crop being grown.
For example, wheat and corn may require different formulations depending on the region. In areas with drought conditions and low fertility, nitrogen and phosphorus fertilizers are essential. In regions where water is abundant but potassium levels are low, adding potassium fertilizer can significantly improve efficiency.
Crops like tobacco and sweet potatoes should avoid chlorine, so sulfur and potassium-based fertilizers are recommended. Trace elements such as boron, manganese, copper, zinc, molybdenum, iron, and chloride play important roles, but their necessity depends on the specific soil and crop conditions.
Brassica crops, such as rapeseed, benefit from added boron in the formula. Corn that lacks zinc requires higher amounts of zinc fertilizer. Garlic thrives with sulfur, making phosphogypsum an excellent addition. Cotton benefits from molybdenum and calcium, which help boost yield and quality.
Most fruit trees prefer iron, and adding black pods or organic matter to the soil can enhance their growth. The formula has received recognition and is widely promoted across Henan Province for its effectiveness and affordability.
Each county has a local station responsible for promoting these formulas, and these stations are usually under provincial supervision. The main brand is "Wo Li," while another popular one is "Chuang Li." For many years, this approach has been praised for delivering high-quality results at a low cost. It’s a practical and science-backed method that helps farmers achieve better harvests.
