About Perdas na Colheita
The Harvest Loss 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 assessment of grain losses during harvesting operations.
🌾 MAIN FEATURES:
📊 LOSS ASSESSMENT
• Calculation of losses on the cutting platform
• Losses due to threshing and separation
• Losses due to grains in the soil
• Results in kg/ha and sacks per hectare
⚙️ HARVESTER ADJUSTMENT
• Identification of misadjustments
• Suggestions for adjustments
• Optimization of harvesting parameters
• Reduction of waste
🧮 ASSESSMENT METHODS
• Square method (0.5 m²)
• 1 m² square method
• Grain counting
• Grain weight
💰 ECONOMIC IMPACT
• Calculation of loss per hectare
• Estimation of total crop loss
• Cost-benefit analysis of adjustments
• Value of loss in reais (Brazilian currency)
📈 ANALYSIS OF EFFICIENCY
• Percentage of losses
• Comparison with acceptable standards
• Harvest history
• Trends over time
✅ BENEFITS:
• Intuitive and easy-to-use interface
• Works offline - ideal for field use
• Multiple evaluation methods
• Precise calculations based on technical standards
• 100% free and ad-free
👨🌾 IDEAL FOR:
• Farmers and rural producers
• Combine harvester operators
• Agricultural technicians
• Agronomists and consultants
• Agricultural cooperatives
• Harvesting service providers
📱 EASY TO USE: Simply collect samples in the field using the sampling square, count or weigh the lost grains, and the app automatically calculates the losses and their economic impact.
🔬 TECHNICAL BASIS:
Based on Embrapa recommendations and technical standards for evaluating grain harvest losses, especially soybeans, corn, and wheat.
🎯 REFERENCE STANDARDS:
• Soybeans: acceptable losses up to 60 kg/ha (1 sack/ha)
• Corn: acceptable losses up to 120 kg/ha (2 sacks/ha)
• Wheat: acceptable losses up to 90 kg/ha (1.5 sacks/ha)
⚠️ IMPORTANCE:
Harvest losses represent significant losses. A loss of just 2% in 100 hectares of soybeans can represent more than 200 sacks lost! This application helps to identify, quantify, and reduce these losses.
🔧 TECHNICAL FEATURES:
• Automatic unit conversion
• Adjustment for grain moisture
• Calculation for different crops
• Report export
Developed by precision agriculture experts, the app is constantly updated with industry best practices.
