Composting Dried Mango Leaves in Eastern Paraguay

Create healthy compost from dried mango leaves using diluted urine (for nitrogen) and molasses water (for microbial activity) in Eastern Paraguay’s sandy, dry climate. Follow these steps for a 1 m³ pile of loosely heaped leaves.

Materials

Dried mango leaves: Carbon source (C:N ratio ~50:1).
Urine: Nitrogen source (C:N ratio ~0.8:1).
Molasses: Sugar source for microbes.
10 L watering can: For applying diluted urine and molasses water.

Steps

Prepare Leaves: Use whole dried mango leaves, loosely heaped to ensure airflow and prevent matting.
Add Diluted Urine: Mix 1 part urine with 10 parts water in a 10 L watering can. Apply one 10 L can of diluted urine (1:10) to 1 m² of loosely heaped leaves (~0.1 m³, 5-10 kg) to achieve a ~30:1 C:N ratio. Mix well.
Add Molasses Water: Mix 20 mL molasses with 10 L water in a watering can. Apply one 10 L can of molasses water to 1 m³ of leaves to boost microbes. Mix thoroughly.
Maintain Pile:
- Moisture: Keep pile like a wrung-out sponge (50-60% moisture). Water with a 10 L can as needed in dry climate.
- Aeration: Turn pile every 1-2 weeks to prevent matting and ensure oxygen.
- Cover: Use leaves or tarp to reduce evaporation on sandy soil.
Monitor: Pile should heat to 55-70°C within days. Compost is ready in 3-6 months when dark, crumbly, and earthy-smelling.

Material	C:N Ratio
Dried Mango Leaves	~50:1
Human Urine	~0.8:1
Wood Chips	~100:1
Ready Compost	~20-30:1

Possible Problems and Solutions

Symptoms	Cause	Remedy
Ammonia smell	Too much urine (excess nitrogen)	Add more leaves, turn pile.
Rotten egg smell, slow breakdown	Matted leaves, poor aeration	Turn pile, mix in straw for airflow.
Dry pile, no heat	Low moisture (dry climate)	Add 10 L water per 1 m², cover pile.
Slow decomposition	Low nitrogen or microbial activity	Apply one 10 L can diluted urine (1:10) or molasses water per 1 m².
Pests (ants, flies)	Excess molasses attracting insects	Reduce molasses, mix well, cover pile.
White crust on pile	Salt buildup from urine	Add 10 L water to leach salts, mix well.

Tips for Eastern Paraguay

Sandy Soil: Use a bin (e.g., pallets) to retain moisture.
Dry Climate: Compost in shade or wet season (Oct-Mar) to reduce watering needs.
Use: Mix finished compost with soil (1:3 ratio) to improve water retention. Add wood ash (potassium source) if needed.

Nutrient	Content (approx.)
Potassium (K)	5-10%
Calcium (Ca)	25-50%
Phosphorus (P)	1-2%

Expected Result: Nutrient-rich compost in 3-6 months, ideal for sandy soils.
