Soil Testing
When & how to test
Test soil every 2-3 years or before a new crop rotation. Measure pH, NPK, organic matter, EC, micronutrients.
1
Take 15-20 sub-samples per field using zigzag pattern
2
Mix into composite sample, send 500g to lab
3
Interpret results against crop-specific optimal ranges
4
Apply corrective amendments before planting
⚖️
pH Management
Optimal ranges
Most crops prefer pH 6.0–7.0. Acidic soils: apply agricultural lime. Alkaline soils: use sulfur or ammonium sulfate.

🔄
Crop Rotation
4-year plan
Rotation breaks pest cycles, improves fertility, reduces disease.
Y1
Legumes (fix nitrogen — soy, chickpea, lentil)
Y2
Cereals (wheat, barley — exploit nitrogen)
Y3
Root crops (potato, beet — break cereal pests)
Y4
Brassicas or fallow (soil rest, weed break)
💧
Drip Irrigation
Best for: vegetables, fruits
Most water-efficient method (90-95% efficiency). Delivers water directly to root zone.
Setup: Emitters every 30-50cm, flow 2-4 L/hr. Use pressure regulators (0.5-1.5 bar). Frequency: Daily or every 2 days based on ETc. Fertigation: Inject soluble fertilizers through drip system for 30-40% more efficiency.
🌊
Flood / Furrow
Best for: rice, large cereals
Low cost, suitable for flat terrain. Efficiency 40-65%.
Furrow depth: 20-25cm for most cereals. Application rate: 60-90mm per irrigation event. Scheduling: Apply when soil moisture falls to 50% depletion of field capacity. Leveling: Laser-level fields to reduce runoff by 30%.
💦
Sprinkler Systems
Best for: cereals, pastures
Efficiency 70-85%. Good for large areas and undulating terrain.
Types: Center pivot (large-scale), lateral move, solid set. Application rate: 5-15mm/hour — must not exceed soil infiltration rate. Timing: Irrigate at night or early morning to reduce evaporation losses. Frost protection: Sprinklers can protect crops at -2°C to -8°C.
🔍
Integrated Pest Management (IPM)
4-tier approach
1
Prevention: Use resistant varieties, clean seed, proper spacing, crop rotation
2
Monitoring: Scout fields weekly, use pheromone traps, economic thresholds
Chemical control: Only when threshold exceeded, least toxic option first

Remote Sensing
NDVI & crop health
Use satellite imagery (Sentinel-2, Landsat) or drone NDVI to assess crop vigor. NDVI ranges: 0.2-0.4 sparse vegetation, 0.4-0.7 moderate crop, 0.7-1.0 dense healthy canopy.
Free tools: Google Earth Engine, Crop Monitor (FAO), EOS Crop Monitoring.
📍
Variable Rate Application
GPS-guided precision
Apply fertilizer at variable rates based on soil maps and yield history. Reduces input costs 15-25% while maintaining yields.
Equipment needed: GPS controller, variable rate spreader/sprayer, soil EC maps. Software: AgLeader, John Deere Operations Center, SST Summit.
🌡️
Soil Moisture Sensors
Real-time irrigation triggers
Install tensiometers or capacitance sensors at 20cm and 40cm depth. Automate irrigation to trigger at defined matric potential (e.g., -25 kPa for vegetables).
Saves 20-40% water vs scheduled irrigation. Connects to IoT platforms for remote monitoring.

Biohazard Level:Class A Biosecurity Alert
Aggressive perennial aquatic weed capable of doubling biomass in 5 to 15 days. Forms dense mats that block water intake pumps, choke irrigation flow, and cause severe eutrophication.

Deploy floating boom containment barriers around intake gate.
Initiate mechanical skimmer harvesting before seed dispersal.
