Practicalities of biochar application…

….. onto a flooded field.

Today we added biochar to a flooded paddy in Krabeil Reil, Pouk District. This farm could have been drained, but this was not part of his usual land preparation routine since it is easier to plough when the land is wet. So we went ahead and added biochar on the field which was submerged in about 20cm of water.

Plots were marked out, and the bags put into the plots where they needed to be spread, however the bags quickly soaked up the water in the field and became heavier so were more difficult to spread than on a dry field. After the bags had been emptied, and during this process roughly spread across the plots, it was also more difficult to see how evenly the biochar had been spread.

The flooded paddy meant that incorporation by hand would have been more difficult, but the land will still be ploughed again which will incorporate the biochar sufficiently, then the farmer expects to plant in about one week. The layout of this plot is as in the nearby trial in Krabeil Reil.

There was no sign of the biochar moving from the plots, since most of it sank quickly after application. Some appeared to float for a while before sinking, but since the water was not moving, it was not thought that the biochar was moving away from the plot.
