Takeaways

• 😀 Proper seedling medium is key to preventing seedling diseases. Consider using biotron and sterilized soil to ensure healthy growth.
• 😀 🌧️ Protect seedlings from rainwater to prevent water splashing onto them, which can lead to diseases like damping-off.
• 😀 🧂 While adding small amounts of salt to POC (liquid fertilizer) is acceptable, ensure it's done in the right proportions to avoid harming the plants.
• 😀 🌿 Use calcium hydroxide cautiously, as it can increase soil pH but will not generate gas if kept in a sealed container.
• 😀 💡 Dolomite lime should be used sparingly, as excessive use can affect the soil negatively. It’s useful during extreme weather, like heavy rainfall.
• 😀 💰 Price fluctuations in the agricultural market are inevitable due to overproduction during harvest seasons. Farmers should survey market demand before planting.
• 😀 🌱 If you have shaded land, consider planting ornamental plants or low-light vegetables, and use photosynthetic bacteria to boost plant growth.
• 😀 🦠 Pesticide resistance can develop if pesticides are misused. Follow proper guidelines for pesticide mixing to prevent resistance and ensure effective pest control.
• 😀 🌶️ Chili plants may wilt suddenly due to changes in weather and poor immunity. Ensure they have good growing conditions to minimize stress.
• 😀 💧 Aerated water can improve oxygenation in the soil, promoting microbial activity that supports plant growth and helps combat soil-borne pathogens.

Q & A

Why are my chili seedlings dying despite using sterilized seed media and Trichoderma?

The problem could lie in the growing medium or the sterilization process. Ensure that you are using a balanced medium such as 70% biotron (charcoal husk) and 30% well-decomposed manure or soil. Also, make sure your seedlings are protected from direct rain exposure, as it can cause seedling rot. Sterilizing the media by steaming or using hot water before planting can also prevent disease outbreaks.

Does dolomite lime harm the soil?

Dolomite lime can be harmful if used excessively and continuously. It can be beneficial in certain situations, like balancing pH during extreme weather conditions, but overuse may degrade soil quality. Use small amounts, like 200-300 grams per 20 liters of water, for better results and avoid unnecessary long-term use.

Will calcium hydroxide produce gas if sealed tightly?

No, calcium hydroxide does not produce gas when sealed tightly. It reacts with water to release heat and increase the pH of the solution, but it does not generate gas in a sealed container.

What happens when POC (organic liquid fertilizer) is mixed with salt?

Adding a small amount of salt (about 1 gram per liter) to POC will still allow microbial growth, as long as the salt concentration is controlled. Salt should be used sparingly, as excessive amounts can harm both plants and beneficial microbes in the soil.

Is activating Trichoderma in leachate effective?

Yes, Trichoderma can be effectively activated in leachate. To do so, mix 100 grams of Trichoderma, 100 grams of sugar, and 50-100 grams of carbohydrates with 1.8 liters of leachate. Let the mixture activate for 5 days, which will enhance microbial activity and promote plant health.

Why do farmers face low prices during harvest season?

Low prices during harvest seasons are due to oversupply in the market, where the supply of produce exceeds demand. To combat this, farmers should explore alternative markets, identify crops with consistent demand, and possibly work with local businesses to avoid selling at a loss.

Which crops grow well in shaded or limited sunlight areas?

In areas with limited sunlight or shade, consider growing ornamental plants or certain vegetables like leafy greens. Additionally, applying photosynthetic bacteria can help enhance the photosynthesis rate of horticultural crops, improving growth despite limited light.

Why are fungal pests harder to control now compared to before?

Fungal pests are harder to control due to the development of resistance, often from improper pesticide use (e.g., using incorrect dosages or mixing incompatible products). Overuse of the same pesticides can cause pests to become resistant, making control more difficult. It's crucial to follow proper pesticide mixing guidelines and rotate chemicals.

Why do chili plants wilt and die suddenly during rain in hot weather?

Chili plants may wilt and die suddenly due to stress caused by rapid changes in temperature and humidity during rain in hot weather. These conditions weaken the plant's immune system, making it susceptible to diseases. Using resistant varieties and ensuring proper care can mitigate this issue.

What is the effect of aerator water on plants?

Water enriched with oxygen, when applied to plants, increases microbial activity in the soil. This enhances nutrient breakdown, produces beneficial metabolites, and helps suppress pathogens, improving overall plant health and growth.
