Why is the soil removed from vehicles leaving Newfoundland?
This is what countries do to keep something from spreading to other countries. Preventitive measure to keep parasasites and deseases from spreading. Usually it is just a preventitive. I heard coutries that had mad cow desease and that sort of thing do this. That sort of thing. I dont know exactly what New Foundland possibly has, but this is why they do it.
turning over soil implies just that, normally a spade is used, digging in a full spade depth; you then removed the soil and flip it over and back into the hole you just removed it from. Essentially bringing soil from below ground to the top and moving the soil from the top part down to the bottom of the hole. the process is repeated over a given area
Inaccuracy in the particle size and therefore in soil characterization, classification and texture is the reason for why organic matter has to be removed in soil hydrometer tests. Samples may contain carbonates, organic matter, oxides and soluble salts. All four of the above-mentioned soil constituents need to be removed since they bind soil particles into bigger sizes.
By either leaving the soil to go fallow which is leaving it to grow weeds for a year to allow the nutrients to return to the soil naturally or you could plant specific plants that compensate each others nutritional needs such as one type that requires alot of nitrogen with one that releases alot of nitrogen as it rots down. You can also add manure to the soil or you can use man made fertilisers…
