The productivity map of your corn industry and variable fee fertilizer application recommendations on EOSDA Crop Checking. The sector on the screen higher than is divided into five zones based on the NDVI index. Based on the map, samples needs to be taken in various zones of the sector with reduced vegetation, taking note of Zone 3 and Zone four.
The surface area geology about the whole examine spot comprises the Tertiary Dupi Tila development, which unconformable overlays the Gondwana (Permian) coal-bearing sediments. These are typically folded into an asymmetric syncline or basin, whose axis strikes around north-south. An important fault varieties the eastern limit in the deposit, beyond which, Archaean basement rocks (Pre-Cambrian) are current promptly below the Dupi Tila. Many lesser faults were recognized within the coal basin by geophysical seismic survey. The Gondwana sequence comprises predominantly sandstones, with subordinate siltstones and mudstones, which have up to 6 coal seams within the centre on the basin. The bottom of such, Seam VI could be the principal concentrate on seam of the Barapukuria coal mine which seam has an average thickness of 36 m (Imam 2013).
