Cálculo de Calagem

About Cálculo de Calagem

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.

Developed by the Applications Laboratory (LAPPS Studio) of FATEC Shunji Nishimura in Pompeia/SP, Brazil.
