How to Apply Organic Fertilizer in Orchards in Spring? Detailed Methods and Techniques

Precautions: Choosing commercial organic fertilizer. First, clarify the source of the raw materials. Second, conduct a small-area trial demonstration with the chosen commercial organic fertilizer first. Be careful to apply it after it is fully decomposed. Most organic fertilizers, such as newly purchased chicken manure and cow manure, often carry harmful substances such as pathogens, and using them directly is harmful to crops, so they should be piled up for fermentation before use.

Precautions: Controlling the application rate. Organic fertilizer has a large volume and low nutrient content, and must be applied in large amounts to meet crop needs, but more is not always better. Fruit crops have relatively high fertilizer requirements, generally around 2000 kg.

Precautions: Combining organic and inorganic fertilizers. Organic fertilizer has complete nutrients, but supply is often insufficient during peak crop growth demand; inorganic fertilizer decomposes easily and is conducive to crop absorption, but has insufficient lasting effect. Applying organic and inorganic fertilizers together can meet crop fertilizer requirements.

Precautions: Mainly deep application as base fertilizer. Organic fertilizer has a lasting effect and releases nutrients slowly, so it is generally applied as a base fertilizer. Applying organic fertilizer during deep plowing helps soil and fertilizer blend together, promotes the formation of soil aggregates, and effectively improves soil properties.

Apply in combination with biological fertilizer. The biological bacteria in biological fertilizer can accelerate the decomposition of organic matter in organic fertilizer, and at the same time can decompose and transform harmful substances in organic fertilizer. Generally, when applying organic fertilizer as a base, 150-200 kg of biological fertilizer can be applied per mu; when applying as a top dressing, 20-25 kg can be applied per mu.
