ಸಾವಯವ ಕೃಷಿಗೆ ಬದಲಿಸಿದ ಮೇಲೆ ಫಲ ಕಡಿಮೆಯಾಗುವ ಕಾರಣ | C:N ಅನುಪಾತದ ರಹಸ್ಯ

In this video, I share my personal journey of managing a coconut orchard through conservation agriculture practices – without chemical fertilizers and tillage. Starting in 2019, I adopted three principles:
✅ Minimum tillage
✅ Mulching with coconut fronds and natural weeds
✅ Maintaining biodiversity in weeds (no intercropping)

Initially, I faced yield reduction due to the sudden withdrawal of chemicals. Later, I realized the problem was nutrient imbalance caused by high C:N organic matter like coconut fronds and grasses. Microbes decomposing these materials consumed soil nitrogen, leading to temporary nitrogen deficiency, bud withering, and yield loss.

To overcome this, I introduced practices to balance the C:N ratio:
🌱 Growing low C:N green manure crops (velvet beans, horse gram, glyricidia)
🌱 Applying cow dung slurry + cow urine, enriched with Trichoderma culture
🌱 Recycling coconut fronds to release potash after decomposition

👉 By supplying low C:N organic matter, microbes decompose faster without robbing nitrogen from soil. In return, they release nutrients back to crops. This way, if we feed microbes smartly, they feed our crops richly.

This approach not only restores yield but also builds long-term soil fertility in a sustainable way.

💡 Tip for weekend farmers: If cow dung or cow urine is not easily available, at least grow green manure crops in your orchard to avoid nutrient lock-up.
