What are the main components of plant ash?
In traditional farming wisdom and modern horticultural practices, plant ash has always occupied a unique position. This natural product is not only a catalyst for plant growth but also an important resource for ecological agriculture.
In-depth interpretation of the core components of plant ash
A treasure trove of mineral elements
Plant ash contains 6%-12% potassium carbonate, and its water-soluble characteristics make it a quick-acting potassium source. In addition to the main components, it also contains 1.5%-3% phosphorus, as well as a perfect combination of trace nutrients such as iron, magnesium, and zinc, forming a unique mineral element matrix.
Analysis of acidity and alkalinity characteristics
The pH value is maintained between 11.6-12.5, which is alkaline. This property gives it unique advantages in soil improvement, especially suitable for neutralizing acidic soil and adjusting the physical structure of compacted clay.
Guidelines for the application of plant fertilizer technology
Principles of crop adaptation
It is particularly effective for solanaceous plants (potatoes, tomatoes) with a high demand for potassium, cucurbitaceous crops (watermelons, pumpkins), and economic crops such as grapes. Experimental data show that reasonable application can increase the yield of solanaceous fruits by 15%-22%.
Scientific application methods
① Base fertilizer application: 50-100 kilograms per mu, needs to be thoroughly mixed with the tillage layer; ② Foliar spray: When configuring a 3% extract, it must be filtered three times to avoid leaf burn; ③ Seedling application: As a mulch, maintain a 1cm thickness to improve the germination rate.
Compatibility taboos
Strictly prohibited from mixing with ammonium nitrogen fertilizers (ammonium sulfate, ammonium bicarbonate) to avoid nitrogen volatilization loss. When used in combination with calcium superphosphate, it is recommended to apply with an interval of 7-10 days to prevent phosphorus element fixation failure.
Case studies of ecological agricultural practice
In organic grape cultivation, using plant ash in combination with fermented compost can effectively prevent downy mildew, and increase the fruit sugar content by 2-3 degrees Brix. When used in potted flowers, adding 5% of the matrix can significantly enhance the ability to resist lodging.
In summary, as a natural mineral fertilizer, plant ash has demonstrated unique value in modern sustainable agriculture. Mastering its alkalinity characteristics and element composition, combined with scientific application techniques, can revitalize traditional resources and provide reliable support for the healthy growth of plants.
