What are the benefits of applying organic fertilizer to peanuts for their growth and development?
What is peanut stem rot? Peanut stem rot is also called peanut stem rot disease or foot rot. Before the seedlings emerge, the affected cotyledons turn dark brown. The pathogen invades the base of the plant stem along the cotyledon stalk, first producing lesions that ooze yellow fluid, which later turn brown. As the lesions develop, they cause the tissue at the stem base to rot. When the lesions expand and encircle the stem base, the aboveground part wilts...
(1) Organic fertilizer contains various nutrient elements such as nitrogen, phosphorus, and potassium, making it a complete fertilizer with comprehensive nutrients. Organic fertilizer has high fertilizer efficiency, long-lasting effects, and stable effectiveness, and can continuously supply the nutrients needed throughout the life of the peanut. (2) Organic fertilizer is composed of excreta and remains produced in the life activities of animals and plants. During fermentation and decomposition, these substances generate heat, raise the soil temperature, promote the activity of microorganisms and rhizobia, accelerate soil maturation, and benefit the activity of roots and rhizobia.
(3) Long-term application of organic fertilizer can improve the soil and enhance the soil's capacity to store water, conserve moisture, and retain fertilizer.
(4) Through microbial decomposition, organic matter synthesizes humus and decomposes to produce elements such as nitrogen, phosphorus, and potassium. At the same time, it produces carbon dioxide, increases carbon nutrition, and helps the decomposition and transformation of mineral fertilizers.
(5) Mixing organic fertilizer with chemical fertilizer can fully leverage the role of chemical fertilizer.
