Aim and basis | उद्देश्य और आधार
English
Calculate nutrient sources for a hypothetical exercise and observe approved application. Record whether the target is per tree or per area and whether P/K are oxide or elemental units. Check product grade and credit nutrients from all sources. Calculation is not proof of chemical compatibility or a crop recommendation.
हिन्दी
काल्पनिक लक्ष्य गणना और स्वीकृत प्रयोग देखें।प्रति पेड़/क्षेत्र औरP/K आधार लिखें।grade,सभी source credit लें।गणना chemical compatibility/crop recommendation नहीं।
Worked example | हल
English
Suppose a teaching target is100gN and50gP2O5 per unit. DAP18-46-0 required=50/0.46=108.70g, supplying19.57gN. RemainingN=80.43g;46%N urea required=80.43/0.46=174.86g. Recheck totals before rounding. These amounts are not an orchard dose recommendation.
हिन्दी
उदाहरण100gN,50gP2O5 लक्ष्य।DAP108.70g सेN19.57g;शेष80.43gN,urea174.86g।rounding पहले कुल जाँचें।ये बाग dose नहीं।
Mixing and placement | मिश्रण और स्थान
English
Do not physically combine products merely because their nutrient arithmetic works. Moisture,chemical reactions,solubility and storage can make mixtures unsuitable. Use only supervisor-verified compatible materials and an approved application method; protect trunk/roots and avoid concentrated contact with young tissue.
हिन्दी
केवल गणित मिलने से उत्पाद न मिलाएँ।नमी,reaction,घुलनशीलता,storage से मिश्रण अनुपयुक्त हो सकता।supervisor verified compatibility और विधि लें;तना-जड़/युवा ऊतक से concentrated संपर्क बचाएँ।
Record | रिकॉर्ड
English
Table:target,grade,product mass,nutrient supplied,credits,placement,date and conditions. Record mass units consistently and distinguish planned from actually weighed quantities. Observe response over time; immediate leaf colour is not a complete assessment of nutrient-use efficiency.
हिन्दी
लक्ष्य,grade,भार,दिया पोषण,credit,स्थान,date,दशा लिखें।इकाई समान,planned/वास्तविक तौला अलग।बाद प्रतिक्रिया देखें;तुरंत रंग पूरी दक्षता नहीं।
Practice / Record | अभ्यास / रिकॉर्ड
Ignoring DAP nitrogen would cause excess totalN in the example.
DAP काN भूलने से कुलN अधिक होगा।
Self-check & viva | स्वयं जाँच
Try answering before opening the answer. / पहले स्वयं उत्तर दें।
DAP for50gP2O5 at46%? | कितना?
108.70g approximately. |लगभग108.70g।
Does arithmetic establish compatibility? | क्या?
No. | नहीं।
Exam answer plan: define the term, explain the mechanism, add a labelled diagram or calculation where relevant, state assumptions and limitations. / उत्तर क्रम: परिभाषा, क्रियाविधि, उपयुक्त चित्र/गणना, शर्तें और सीमाएँ।
