While the tractor tracks and places in their immediate vicinity (up to tens of centimeters) (photo) have certainly several times higher conductivity against the rest of the field, described places created by sowing machine may exhibit conductivity increased by tens of percent.
Wakati tracks trekta na maeneo ya jirani yao haraka (hadi kumi ya sentimita) (picha) na hakika kadhaa Times Higher conductivity dhidi ya mapumziko ya shamba, Ikielezewa maeneo zilizoundwa na mashine ya kupanda yaweza kuonyesha conductivity Kuongezeka kwa makumi ya asilimia.
