🌱 SOIL TESTING SOP Agarwood Plantation – Step-by-Step Standard Procedure 🌿 Introduction Agarwood एक high-value और sensitive plantation species है। सफल plantation की सबसे पहली और सबसे महत्वपूर्ण प्रक्रिया है — scientific soil testing। सही soil selection plantation risk को कम करता है, growth improve करता है और long-term ecological sustainability सुनिश्चित करता है। ✅ 1. Objective of Soil Testing Soil testing का मुख्य उद्देश्य: ✔ Soil suitability check करना ✔ Fertility level समझना ✔ Drainage capacity analyse करना ✔ Plantation risk minimize करना 👉 Agarwood sensitive plant है — गलत soil selection भारी financial loss का कारण बन सकता है। 🕒 2. When to Do Soil Testing ✔ Best Time Plantation से 2–3 महीने पहले Summer season (April–May) ideal ❌ Avoid Monsoon season Fertilizer application के तुरंत बाद 🌾 3. Soil Sampling SOP (Field Level) Step-by-Step Collection Method 📍 Step 1 — Sampling Spots Select करें 1 acre land = minimum 5 samples Zig-zag pattern में sampling करें 📍 Step 2 — Depth of Sampling Top soil depth: 6–8 inches Grass और debris पहले remove करें 📍 Step 3 — Sample Collection Required Tools: Soil auger / spade Clean bucket Sample bags Process: 5 spots से soil लें Properly mix करें 500 gm composite sample तैयार करें 📍 Step 4 — Labelling Clearly लिखें: Farmer name Village name Survey number Sampling date 🔬 4. Parameters to Test (Most Important) 🌿 Soil pH Ideal: 5.5 – 7.5 Problem: High pH → Nutrient lock Low pH → Root damage 🌿 Soil Texture Best: ✔ Sandy loam ✔ Loamy soil Avoid: ❌ Heavy clay soil ❌ Rocky soil 🌿 Organic Carbon Ideal level: 👉 Above 0.5% Low carbon = Poor plant growth 🌿 NPK Levels Essential nutrients: Nitrogen (N) Phosphorus (P) Potassium (K) 🌿 Drainage Capacity Check: Water infiltration rate Water holding capacity 🌿 Salinity / EC Ideal EC: 👉 Less than 1 dS/m 🧪 5. Laboratory Testing SOP Where to Test Govt Soil Testing Lab Krishi Vigyan Kendra (KVK) Certified private labs Submission Process Soil testing form fill करें Labelled sample submit करें Receipt collect करें Report Timeline 👉 Usually 7–15 days 📊 6. Interpretation SOP (Very Important) Agarwood Soil Suitability Scale Parameter Suitable Not Suitable pH 5.5–7.5 Above 8 Organic Carbon >0.5% <0.3% Drainage Good Waterlogging EC <1 >2 🔧 7. Soil Correction SOP (If Unsuitable) Problem Solution High clay soil Add sand, FYM, compost Low organic carbon Vermicompost, green manure, cow dung High pH soil Gypsum + organic compost Waterlogging risk Drainage channels, raised beds 📁 8. Documentation SOP Kisan Mitra must maintain: ✔ Soil testing report file ✔ Field mapping record ✔ Soil correction recommendation sheet ⚠️ 9. Risk Warning SOP Never start plantation if: ❌ Soil pH above 8.5 ❌ Permanent waterlogging ❌ Hard rocky land ⭐ Golden Rules of Soil Testing ✔ Always take composite sample ✔ Test before plantation planning ✔ Never skip drainage check ✔ Follow soil correction advice 📋 Simple Soil Testing Checklist (Field Use) Before plantation confirm: ☑ Soil sample collected ☑ Lab test completed ☑ Report verified ☑ Soil suitability confirmed ☑ Corrections applied
