Oil Mill Essentials: "Peanut Meal"
In the corner of traditional oil mills, large amounts of unassuming peanut meal are often stacked. This oil pressing byproduct is rich in organic matter and can even become a golden fertilizer for plant growth after scientific treatment. This article will delve into the secrets of using peanut meal for flowering, and introduce you to a natural nutrient solution for home gardening.
The Plant Nutrition Code of Peanut Meal
Treasure trove of Organic Matter and Trace Elements
Peanut meal contains 5.8% nitrogen, 1.3% phosphorus, and 1.5% potassium, as well as abundant amounts of calcium, magnesium, and other medium elements. Its crude protein content is as high as 45%, and it can produce 18 amino acids after decomposition. These components form a slow-release nutrient matrix that continuously nourishes plant roots.
Microbial Activation Mechanism
The actinomycetes produced during the fermentation process can effectively inhibit soil-borne diseases. Each gram of fermented product contains 230 million CFU of live bacteria, significantly improving the soil microecology. Experimental data show that the soil porosity increases by 27% and the water retention capacity improves by 35% when using peanut meal.
Four-Step Practical Application Method
Raw Material Pre-treatment Techniques
Place the peanut meal in a 45°C environment and expose it to sunlight for 6 hours, achieving a 99% UV sterilization rate. Add 3% diatomaceous earth during grinding to accelerate the grinding efficiency and increase mineral content. controlling the particle fineness between 80-120 mesh is most beneficial for fermentation.
Smart Fermentation Technology
Oil Mill Essentials: "Peanut Meal"
Adopt a three-stage temperature-controlled fermentation: maintain 28°C for the first 3 days to activate the strains, 35°C for the middle 7 days to accelerate decomposition, and reduce to 25°C for the last 15 days to stabilize the nutrients. Add 2% brown sugar as a catalyst to reduce the fermentation period to 22 days.
Scientific Application Scheme
Mix with the substrate at a 1:15 ratio, adding 8-10 grams per liter of soil for potted plants. For ground plants, apply along the drip line in a 15cm deep circular trench, and using it with Trichoderma can increase nutrient absorption by 42%. It is recommended to apply once in spring and autumn.
Safety Guidelines
Unfermented raw material contains 3.2% free fatty acids, which can cause a sudden drop in pH if used directly. It is recommended to mix with 5% wood ash to adjust the acid-base balance. For succulent plants, dilute to 1/3 concentration, and for orchid plants, use with pine phosphorus to prevent root rot.
By systematically using peanut meal fertilizer, the number of roses can increase by 60%, and the growth rate of pothos can increase by 45%. This combination of traditional wisdom and modern horticulture has opened up a new eco-friendly and economical path for home gardening. It is recommended to use an EC value tester to monitor soil fertility, making plant care more scientific and precise.
