Cálculo de Calagem

Liming calculator for soil correction using agronomic methods.

The Liming Calculation tool is essential for farmers, agricultural technicians, and agribusiness professionals. Developed by FATEC Shunji Nishimura in Pompeia/SP, this application allows for the precise calculation of the amount of lime needed for soil correction.

🌱 MAIN FEATURES:

📊 BASE SATURATION METHOD
• Calculation based on base saturation (V%)
• Considers CEC, current V, and desired V
• Automatic adjustment for limestone PRNT
• Results in t/ha (tons per hectare)

⚗️ ALUMINUM NEUTRALIZATION
• Alternative method based on exchangeable Al
• Considers soil Ca and Mg content
• Recommendation for acidic soils

🧪 GYPSUM CALCULATION
• Determination of agricultural gypsum needs
• Correction of subsurface layers
• Consideration of clay content

📅 APPLICATION PLANNING
• Corrective application schedule
• Split application of high doses
• Ideal application time

💰 COST ANALYSIS
• Investment calculation per Hectare
• Comparison between limestones
• Total cost per area

✅ BENEFITS:

• Intuitive and easy-to-use interface
• Works offline - ideal for field use
• Multiple calculation methods
• Precise calculations based on agronomic formulas
• 100% free and ad-free

👨‍🌾 IDEAL FOR:

• Farmers and rural producers
• Agricultural technicians
• Agronomists and consultants
• Agronomy students
• Agricultural cooperatives

📱 EASY TO USE: Simply enter the soil analysis data (pH, CEC, base saturation, nutrient content) and the application automatically calculates the amount of limestone needed.

🔬 TECHNICAL BASIS:
Based on the recommendations of IAC Bulletin 100 and Embrapa methodologies for correcting tropical soils.
