MICRONUTRIENTS : |
|
|
13 STL’s are equipped for the analysis of Micronutrient in soil samples
|
|
|
Karnal, Ambala, Jagadhari, Gurgaon, Narwana, Rohtak ,Mohindergarh, Rewari, Hansi,
Sirsa, Jind, Ballabgarh and Gohana |
|
|
Four micronutrient- Zn, Fe, Mn & Cu are analysed in the laboratories
|
|
|
Critical limits of Micronutrients :
|
|
|
Zn < O.6 ppm Fe < 4.5 ppm
Mn < 2.0 ppm Cu < 0.2 ppm
|
|
|
1.0 lakh samples are analysed annually for micronutrients
|
|
|
Remaining Laboratories are being upgraded for micronutrient analysis
In phased manner
